Abstract
We have discovered a protein with an amino acid composition exceptionally rich in glycine and cysteine residues in the giant virus mimivirus. This small 6 kDa protein is among the most abundant proteins in the icosahedral 0.75 μm viral particles; it has no predicted function but is probably essential for infection. The aerobically purified red-brownish protein overproduced inEscherichia coli contained both iron and inorganic sulfide. UV/vis, EPR, and Mössbauer studies revealed that the viral protein, coined GciS, accommodated two distinct Fe-S clusters: a diamagnetic S = 0 [2Fe-2S]2+ cluster and a paramagnetic S = 5/2 linear [3Fe-4S]1+ cluster, a geometry rarely stabilized in native proteins. Orthologs of mimivirus GciS were identified within all clades of Megavirinae, a Mimiviridae subfamily infecting Acanthamoeba, including the distantly related tupanviruses, and displayed the same spectroscopic features. Thus, these glycine/cysteine-rich proteins form a new family of viral Fe-S proteins sharing unique Fe-S cluster binding properties.

Abstract
Abstract
Skipping breakfast and late-night-eating have been associated with risk factors for type 2 diabetes (T2D). However, less is known about the link between daily timing and frequency of food intake and risk of developing T2D. The objective of the present study is to investigate the associations between circadian nutritional behaviours, defined by meal timings and frequency, and risk of T2D. 103,312 adults (79% females, mean age at baseline=42.7) from the French NutriNet-Santé cohort were included. Participants’ circadian nutritional behaviours were assessed using repeated 24 h dietary records. Associations of time of first and last meal of the day, meal frequency and of nighttime fasting duration with risk of T2D were assessed by multivariable Cox proportional hazard models adjusted for known risk factors. During a median follow-up of 7.3 years, 963 new cases of T2D were ascertained. Compared with subjects reporting on average a first meal before 8AM, those having a first meal after 9AM had a higher risk of developing T2D, HR = 1.59 (1.30 to 1.94). A late time of last meal (after 9PM) was associated with a higher risk of T2D, HR = 1.28 (1.06 to 1.54), but this association was no longer significant after adjusting for time of first meal. Each additional eating episode was associated with a reduction of the risk of T2D, HR = 0.95 (0.90 to 0.99), p-value=0.01. Overall, nighttime fasting duration was not associated with risk of T2D, except in participants having breakfast before 8AM after a nighttime fasting duration of more than 13 hours (HR = 0.47, 0.27 to 0.82). In this large prospective study, circadian nutritional behaviours were associated with risk of T2D. Daytime nutritional behaviours and specifically an early first meal was associated with a lower risk of type 2 diabetes. If confirmed in other largescale studies, an early breakfast should be considered in preventive strategies for type 2 diabetes.
Key messages
• If confirmed in other largescale studies, an early breakfast could be considered in preventive strategies for type 2 diabetes.
• Beyond nutritional quality of meals, meal timing could also be a risk factor for type-2 diabetes.

Abstract
Abstract
Background
Nutrition is a well-established risk factor for cardiovascular diseases (CVD) that can be leveraged by public health prevention strategies. In addition to dietary guidelines, front-of-pack nutrition labels (FoPNL) can help consumers make healthier food choices. Nutri-Score, a scientifically validated 5-color FopNL based on the nutrient profile FSAm-NPS has been adopted by several European countries but remains optional under current EU labeling regulation, which is to be revised end of 2022. Scientific evidence is therefore needed on the relevance of the Nutri-Score at the European level. Our objective was to study the association between the consumption of food as graded by the FSAm-NPS and CVD risk in a large European population.
Methods
This prospective analysis was conducted on a case-cohort comprising 13,308 participants without CVD risk factors at baseline, among which 5,326 first incident cases of CVD from the EPIC-CVD study (8 European countries). Food intakes were assessed using country-specific dietary questionnaires. The FSAm-NPS was calculated for each food based on its 100g content in energy, sugar, saturated fatty acid, sodium, fibre, protein, and fruits/vegetables/legumes/nuts. Multi-adjusted Cox models were computed.
Results
Overall, associations were observed between the consumption of foods with a higher FSAm-NPS score (lower nutritional value) and a higher risk of myocardial infarction (MI; HR1-SD=1.12 [1.05,1.21]; HRQ5/Q1=1.23 [1.00,1.52]). Associations with stroke were not significant. Overall, associations were more particularly observed in men.
Conclusions
In this large European population, a higher risk of MI was observed in individuals consuming on average a diet with higher FSAm-NPS foods (reflecting consumption of foods with a lower nutritional value/less favourable Nutri-Score). This adds to the evidence on the relevance of Nutri-Score as a public health tool to help consumers choose healthier food products.
Key messages
• The consumption of foods with a lower nutritional quality as graded by the Nutri-Score was associated with a higher risk of myocardial infarction in the large European EPIC-CVD case-cohort study.
• This adds to the evidence supporting the relevance of the Nutri-Score as a complementary tool to dietary guidelines to help consumers make healthier food choices.

Abstract
Abstract
Nitrates and nitrites are used as food additives in processed meats. They are also commonly ingested from water and several foods. Evidence suggests a beneficial role of dietary nitrites and nitrates in lowering blood pressure. However, associations between exposure to nitrites and nitrates from natural sources and food additives, separately, and risks of hypertension and cardiovascular disease (CVD) have not been investigated. We aimed to study these associations in the French population based prospective cohort NutriNet-Santé. Overall, 104,817 adults were included. Associations between exposure to nitrites and nitrates (evaluated using repeated dietary records, linked to a food composition database accounting for commercial brands of industrial products) and risks of hypertension and cardiovascular disease were assessed using multivariable Cox proportional hazard models. During follow-up, 3810 incident cases of hypertension were ascertained, and 2075 cases of CVD, 1004 of cerebrovascular diseases and 1079 or coronary heart diseases were diagnosed. Participants with higher exposure to nitrites from food additives and specifically those highly exposed to sodium nitrite (e250) had a higher hypertension risk compared with those who are not exposed to nitrites from food additives (HR = 1.19 (95% CI 1.08-1.31), P = 0.002, and 1.19 (95% CI 1.07-1.31), P = 0.002, P < 0.001), respectively). There was no evidence for an association between total nitrites or nitrites from natural sources, or dietary nitrates with hypertension risk (all P-values>0.3). There was no evidence for associations between dietary nitrites, or nitrates with risks of cardiovascular, cerebrovascular or coronary heart diseases (all P-values>0.2). In conclusion, we found that higher exposure to nitrites from food additives was associated with higher risk of hypertension. Our results do not support a potential protective association between dietary nitrites or nitrates and cardiovascular outcomes.
Key messages
• These results provide additional evidence in the context of current discussions about updating regulations on the use of nitrites as food additives.
• Our findings do not support any protective impact of nitrites and nitrates on cardiovascular health.

Abstract
Abstract
Nitrates and nitrites occur naturally in water and soil and are commonly ingested from drinking water and dietary sources. They are also used as food additives. The epidemiological evidence linking exposure to nitrites/nitrates with type-2 diabetes (T2D) risk is scarce. We aimed to study these associations in a large population based prospective cohort study. Overall, 104,168 adults from the French NutriNet-Santé cohort study (median follow-up time 6.7 years) were included. Associations between intakes of nitrites and nitrates (evaluated using repeated 24h dietary records, linked to a comprehensive food composition database and accounting for details of commercial names/brands of industrial products) and risk of T2D were assessed using cause-specific multivariable Cox proportional hazard models adjusted for known risk factors (sociodemographic, anthropometric, lifestyle, medical history, and nutritional factors). During follow-up, 969 incident T2D cases were ascertained. Total nitrites and nitrites from natural sources were both positively associated with higher T2D risk (HRtertile 3 vs.1=1.29 (95% CI 1.06-1.56), Ptrend=0.004, and 1.27 (95% CI 1.05-1.54), Ptrend=0.01, respectively). Participants with higher exposure to nitrites from food additives (i.e. above the sex-specific median), and specifically those having higher exposure to sodium nitrite (e250) had a higher T2D risk compared with those who were not exposed to food additive nitrites (HRtertile 3 vs.1=1.58 (95% CI 1.28-1.94), Ptrend<0.001, and 1.59 (95% CI 1.30-1.96), Ptrend<0.001), respectively). There was no evidence for an association between nitrates of any source and T2D risk (all Ptrend>0.4). In this large prospective cohort, a higher dietary exposure to nitrites (from both natural sources and food additives) was associated with higher T2D risk. These results provide additional evidence in the context of current discussions about updating regulations on the use of nitrites as food additives.
Key messages
• A high exposure to dietary nitrites (from both natural and food additive sources) is associated with an increased risk of type-2 diabetes.
• These findings support further regulations concerning the use of nitrites as food additives in processed meats.

Abstract
Abstract
Background
Artificial sweeteners are widely used today by the food industry as sugar alternatives. Potential adverse effects of these food additives on cardiovascular disease (CVD) have been suggested in experimental studies, but data from studies involving humans remain very limited. Previous cohorts have focused on artificially sweetened beverages. Our objective was to study the associations between artificial sweeteners from all dietary sources, overall and by molecule (aspartame, acesulfame-potassium and sucralose), and risk of CVDs (overall, coronary heart and cerebrovascular).
Methods
The study included 103,388 participants of the web-based NutriNet-Santé cohort (2009-2021). Artificial sweetener intakes were assessed using repeated 24h dietary records including names and brands of industrial products consumed. Multi-adjusted Cox proportional hazard models were performed. Exposure to artificial sweeteners were coded as 3-category variables: non-consumers, lower consumers (artificial sweetener intake below the sex-specific median) and higher consumers (above the sex-specific median).
Results
Compared to non-consumers, higher consumers of total artificial sweeteners had increased risk for CVD (n = 1502 incident cases, HR = 1.17 [1.01-1.35], P-trend=0.04) and more specifically cerebrovascular diseases (n = 777, HR = 1.34 [1.10-1.62], P = 0.004). Higher consumption of aspartame was associated with increased cerebrovascular diseases (HR = 1.29 [1.03-1.60], P = 0.01). Higher consumption of acesulfame-K was associated with a higher risk of CVD (HR = 1.24 [1.04-1.47], P = 0.02) and cerebrovascular diseases (HR = 1.29 [1.02-1.64], P = 0.1). No association was detected for coronary heart diseases (n = 730 incident cases).
Conclusions
These findings suggest a direct association between higher artificial sweetener consumption and increased CVD risk, in particular cerebrovascular. These results provide key novel information for the ongoing re-evaluation of sweeteners by the European Food Safety Authority.
Key messages
• In this large-scale prospective cohort (n = 103,388), artificial sweeteners (especially aspartame and acesulfame-K) were associated with increased risks of cardiovascular and cerebrovascular diseases.
• These results provide key insights to feed EFSA’s expertise for the ongoing risk assessment of artificial sweeteners.

Abstract
Abstract
Meal timings and daily night-time fasting periods can synchronise the circadian system, which regulates the cardiovascular system. The present study aims to evaluate the prospective associations between circadian nutritional behaviours, defined by meal timing and frequency, and the risk of cardiovascular diseases. We used data from 103,389 adults (79% females) in the French NutriNet-Santé study, 2009-2021. Circadian nutritional behaviours were assessed using repeated 24h food records during the first two years of follow-up. We examined the associations between circadian eating behaviours and risk of cardiovascular, coronary heart and cerebrovascular diseases by multivariable Cox proportional hazard models. During a median follow-up of 7.2 years, 2036 incident cardiovascular diseases were diagnosed. A later first meal of the day was associated with a higher risk of cardiovascular diseases (HR per hour increase = 1.06, 95% CI 1.01 - 1.12). A later last meal of the day was associated with a higher risk of cerebrovascular diseases (HR per hour increase = 1.08, 95% CI 1.01 - 1.15). Among women, a later last meal was also associated with a higher risk of cardiovascular disease (HR per hour increase = 1.08, 95% CI 1.01 - 1.15). We found no evidence for an association between night-time fasting duration nor meal frequency, with risk of cardiovascular diseases. This study suggests that the habit of eating a later first meal, and a later last meal (in women) could be associated with a higher risk of developing circulatory diseases. These results need to be confirmed in other largescale studies before they can be transferable to clinical practice.
Key messages
• Beyond nutritional quality of meals, meal timing could also be a risk factor for cardiovascular disease.
• If confirmed in other largescale studies, early breakfast and dinner could be considered in preventive strategies of cardiovascular diseases.

Abstract
Abstract
Type 2 diabetes (T2D) is one of the most common noncommunicable diseases worldwide, with an increasing prevalence and a considerable global health burden. Substantial evidence has linked consumption of trans fatty acids (TFAs) to an increased risk of cardiovascular disease. However, the effects of T2D remain unclear. We aimed to investigate the associations between different types of TFAs (total, ruminant, industrial and corresponding specific isomers) and risk of T2D in the NutriNet-Santé prospective cohort. Overall, 105,551 participants aged 18 years or older from the French NutriNet-Santé cohort (2009-2021) were included (mean age at baseline=42.7y (SD = 14.6y), 79.2% women). Dietary intake data, including usual TFA intake, were collected using repeated 24-hour dietary records (n = 5.7 [SD = 3.1]). Associations between sex-specific quartiles of dietary intake of TFAs and type 2 diabetes risk were assessed using multivariable Cox proportional hazard models adjusted for known risk factors. A total of 969 incident type 2 diabetes cases occured during follow-up. Total TFAs was associated with higher T2D risk (HRfor quartile 4 versus 1=1.38; 95% CI = 1.11-1.73; Ptrend<0.001). This association, specifically observed for industrial TFAs (HR = 1.45; 95% CI = 1.15-1.83; Ptrend<0.001), was mainly driven by elaidic acid (HR = 1.37; 95% CI = 1.09-1.72; Ptrend<0.001) and linolelaidic acid (HR = 1.29; 95% CI = 1.04-1.58; Ptrend=0.07). In contrast, ruminant trans fatty acids were not significantly associated with the risk of T2D. In this large prospective cohort, higher dietary intakes of total and industrial TFAs were associated with increased T2D risk. These findings support WHO's recommendation to eliminate industrially-produced TFAs from the food supply worldwide. As such, consumers should be advised to limit the consumption of food products containing partially hydrogenated oils (main vector of iTFAs) as this, specifically, may contribute to lower the substantial global burden of T2D.
Key messages
• Higher dietary intakes of total and industrial trans fatty acids were associated with increased type 2 diabetes risk.
• Our findings support WHO’s recommendation to eliminate industrially-produced TFAs from the food supply worldwide.

Abstract
Abstract
Background
Acrylamide is classified as a probable human carcinogen by the IARC but epidemiological evidence on the carcinogenicity of acrylamide from dietary sources is limited. This study aimed to investigate the associations between dietary acrylamide and breast cancer risk in the NutriNet-Santé cohort.
Methods
This prospective cohort study included 80,597 French women (mean [SD] age at baseline: 40.8 [14] years) during a mean (SD) follow-up of 8.8 (2.3) years. Acrylamide intake was evaluated using repeated 24h dietary records (n = 5.5 [SD 3.0]), linked to a comprehensive food composition database. Associations between acrylamide intake and breast cancer risk (overall, premenopausal and post-menopausal) were assessed by Cox hazard models adjusted for known risk factors.
Results
The mean (SD) dietary acrylamide intake was 30.1 (21.9) µg/d (main contributors: coffee, potato fries and chips, pastries and cakes, and bread). During follow-up, 1016 first incident breast cancer cases were diagnosed (431 premenopausal, 585 postmenopausal). A borderline significant positive association was observed between acrylamide intake and breast cancer risk overall (HRQ4 vs Q1= 1.21 [95% CI: 1.00-1.47]) and a positive association was observed with premenopausal cancer (HRQ4 vs Q1= 1.40 [95% CI: 1.04-1.88]). Restricted cubic spline analyses suggested evidence for non-linearity of these associations, with higher HR for intermediate (Q2) and high (Q4) exposures. Receptor-specific analyses revealed a positive association with estrogen receptor-positive breast cancer, which represented 86% of total cancer cases. Acrylamide intake was not associated with post-menopausal breast cancer.
Conclusions
Results from this large prospective cohort study suggest the potential deleterious role of dietary acrylamide in breast cancer etiology, especially in premenopausal women, and provide new insights that should encourage further mitigation strategies to reduce the content of acrylamide in food.

Abstract
Abstract
Background
Food additive emulsifiers are found in thousands of industrial foods and may exert deleterious effects on gut microbiota and carcinogenesis according to experimental studies. However, their associations with cancer risk has not been investigated yet. This study aimed to investigate these associations in a large population-based prospective cohort.
Methods
This study included 102,485 French adults from the NutriNet-Santé cohort (42.1y [14.5], 78.8% female, 2009-2021). Food additive emulsifier intakes were estimated using repeated 24h dietary records linked to brand-specific food composition databases on food additives. Associations with incident cancer risk were assessed using Multivariable Cox models.
Results
3,511 incident cancer cases were diagnosed during follow-up (1,026 breast, 431 prostate, and 279 colorectal cancers). Intakes of sodium citrate (E331, HR = 1.12 [1.02-1.23], p-trend=0.009), xanthan gum (E415, HR = 1.11 [1.02-1.21], p-trend=0.02), and mono- and diglycerides of fatty acids (E471, HR = 1.17 [1.06-1.28], p-trend=0.001 and total: E471, E472a-b-c-e, HR = 1.11, [1.02-1.22], p-trend=0.02) were associated with increased overall cancer risk. Higher intakes of E331 (p-trend = 0.046), sodium stearoyl-2-lactylate (E481, p-trend=0.01), total lactylates (E481-482, p-trend=0.01), total celluloses (E460-468, p-trend=0.03), carob bean gum (E410, p-trend=0.01), and E471 (p-trend=0.006) were associated with increased overall breast cancer risk. Higher intakes of carrageenan (E407, p-trend=0.04), E415 (p-trend=0.02), and triphosphates (E451, p-trend=0.03) were associated with increased post-menopausal breast cancer risk.
Conclusions
These results are the first to investigate and report direct associations between cancer risk and exposures to seven individual and three groups of food additive emulsifiers. If replicated, they may have an important public health impact, considering the omnipresence of these additives in industrial foods globally.
Key messages
• This study is the first to precisely assess exposures to food additive emulsifiers in a population-based study.
• Intakes of food additive emulsifiers were associated with increased risk of cancer.

Abstract
Iron-sulfur (Fe-S) clusters are prosthetic groups of proteins biosynthesized on scaffold proteins by highly conserved multi-protein machineries. Biosynthesis of Fe-S clusters into the ISCU scaffold protein is initiated by ferrous iron insertion, followed by sulfur acquisition, via a still elusive mechanism. Notably, whether iron initially binds to the ISCU cysteine-rich assembly site or to a cysteine-less auxiliary site via N/O ligands remains unclear. We show here by SEC, circular dichroism (CD), and Mössbauer spectroscopies that iron binds to the assembly site of the monomeric form of prokaryotic and eukaryotic ISCU proteins via either one or two cysteines, referred to the 1-Cys and 2-Cys forms, respectively. The latter predominated at pH 8.0 and correlated with the Fe-S cluster assembly activity, whereas the former increased at a more acidic pH, together with free iron, suggesting that it constitutes an intermediate of the iron insertion process. Iron not binding to the assembly site was non-specifically bound to the aggregated ISCU, ruling out the existence of a structurally defined auxiliary site in ISCU. Characterization of the 2-Cys form by site-directed mutagenesis, CD, NMR, X-ray absorption, Mössbauer, and electron paramagnetic resonance spectroscopies showed that the iron center is coordinated by four strictly conserved amino acids of the assembly site, Cys35, Asp37, Cys61, and His103, in a tetrahedral geometry. The sulfur receptor Cys104 was at a very close distance and apparently bound to the iron center when His103 was missing, which may enable iron-dependent sulfur acquisition. Altogether, these data provide the structural basis to elucidate the Fe-S cluster assembly process and establish that the initiation of Fe-S cluster biosynthesis by insertion of a ferrous iron in the assembly site of ISCU is a conserved mechanism.

Abstract
![]()
The heme enzyme chlorite
dismutase (Cld) catalyzes O–O bond
formation as part of the conversion of the toxic chlorite (ClO2–) to chloride (Cl–) and
molecular oxygen (O2). Enzymatic O–O bond formation
is rare in nature, and therefore, the reaction mechanism of Cld is
of great interest. Microsecond timescale pre-steady-state kinetic
experiments employing Cld from Azospira oryzae (AoCld), the natural substrate chlorite, and the
model substrate peracetic acid (PAA) reveal the formation of distinct
intermediates. AoCld forms a complex with PAA rapidly,
which is cleaved heterolytically to yield Compound I, which is sequentially
converted to Compound II. In the presence of chlorite, AoCld forms an initial intermediate with spectroscopic characteristics
of a 6-coordinate high-spin ferric substrate adduct, which subsequently
transforms at kobs = 2–5 ×
104 s–1 to an intermediate 5-coordinated
high-spin ferric species. Microsecond-timescale freeze-hyperquench
experiments uncovered the presence of a transient low-spin ferric
species and a triplet species attributed to two weakly coupled amino
acid cation radicals. The intermediates of the chlorite reaction were
not observed with the model substrate PAA. These findings demonstrate
the nature of physiologically relevant catalytic intermediates and
show that the commonly used model substrate may not behave as expected,
which demands a revision of the currently proposed mechanism of Clds.
The transient triplet-state biradical species that we designate as
Compound T is, to the best of our knowledge, unique in heme enzymology.
The results highlight electron paramagnetic resonance spectroscopic
evidence for transient intermediate formation during the reaction
of AoCld with its natural substrate chlorite. In
the proposed mechanism, the heme iron remains ferric throughout the
catalytic cycle, which may minimize the heme moiety’s reorganization
and thereby maximize the enzyme’s catalytic efficiency.

Abstract
Abstract
Background
Fermentable Oligosaccharides, Disaccharides and Monosaccharides And Polyols (FODMAPs), which are found in a variety of foods (dairy products, fruit, legumes, refined grains, sugary beverages, etc.) have been involved in risk for gastrointestinal disorders. In view of their pro-inflammatory potential and their interactions with the gut microbiota, their contribution to the etiology of other chronic diseases such as cancer has been postulated. However, no epidemiological study has investigated this hypothesis so far. Our objective was to investigate the associations between FODMAP intake (total and by type) and cancer risk (overall, breast, prostate and colorectal).
Methods
104,909 French adults from the NutriNet-Santé prospective cohort (2009-2020) were included (median follow-up time=7.7y). FODMAP intakes were obtained from repeated 24h-dietary records linked to a detailed food composition table. Associations between FODMAPs and cancer risks were assessed by Cox proportional hazard models adjusted for a large range of lifestyle, sociodemographic and anthropometric variables.
Results
Total FODMAP intake was associated with increased overall cancer risk (n = 3,374 incident cases, Hazard Ratio for quintile 5 vs quintile 1=1.21, 95% confidence interval 1.02-1.44, P-trend=0.04). Oligosaccharides seemed to be the FODMAP type particularly associated with cancer risk: a trend was observed for overall cancer (HR = 1.10 (0.97-1.25) P-trend=0.04) and colorectal cancer (n = 272, HR = 1.78 (1.13-2.79) P-trend=0.02). Associations remained stable across a series of sensitivity analyses.
Conclusions
Our findings suggest a potential role of FODMAPs in cancer onset. Further epidemiological and experimental studies are needed to confirm these results and provide data on the potential underlying mechanisms.
Key messages
In this large-scale prospective cohort of French adults, FODMAP intake was associated with increased cancer risk. These associations need to be studied in other prospective cohorts, in order to clarify FODMAPs role in cancer development.

Added sugars' deleterious effects have been established for several chronic diseases, leading food industries to turn towards high-intensity sweeteners. Their safety is debated and findings remain contrasted regarding their role in the etiology of various diseases. In particular, their carcinogenicity has been suggested by several experimental studies but epidemiological data are lacking.
Thus, our objective was to investigate the associations between sweetener intakes (total from all dietary sources, and most frequently consumed: acesulfame-K e950, aspartame e951 and sucralose e955) and cancer risk (overall and by sites).
Methods
Overall, 102,046 adults from the French NutriNet-Santé prospective cohort (2009-2021) were included. Consumption of sweeteners was obtained by repeated 24h-dietary records including brands and commercial names of industrial products. Associations between sweeteners and cancer incidence were assessed by multi-adjusted Cox hazard models.
Results
Compared to non-consumers, high-consumers had higher risk of overall cancer (n = 2527, hazard ratio=1.12, 95% confidence interval=1.00-1.25, P-trend=0.005). In particular, acesulfame-K (HR = 1.18 [1.04-1.34] P = 0.003) and aspartame (HR = 1.20 [1.05-1.38] P = 0.001) were associated with increased cancer risk. Similarly, higher risks were observed for breast (n = 723, HR = 1.25 [1.02-1.53] P = 0.01, HR = 1.39 [1.11-1.74] P = 0.003 and HR = 1.33 [1.05-1.69] P = 0.007 for total sweeteners, e950 and e951, respectively) and obesity-related cancers (n = 1509, HR = 1.16 [1.00-1.33] P = 0.02, HR = 1.23 [1.04-1.45] P = 0.01 and HR = 1.22 [1.02-1.45] P = 0.01 for total sweeteners, e950 and e951, respectively).
Conclusions
These results suggest that artificial sweeteners (especially e950 and e951), which are found in > 12,000 foods and beverage references worldwide, may be associated with increased cancer risk. These findings provide important and novel insights for the ongoing re-evaluation of sweeteners by the European Food Safety Authority.
Key messages
In this large-scale prospective cohort of French adults, intake of high-intensity artificial sweetener intake (especially acesulfame-K and aspartame) was associated with higher risk of cancer. These results provide novel insights to feed EFSA’s expertise for the ongoing risk assessment of artificial sweeteners.

Abstract
Abstract
Dietary trans fatty acids (TFAs) are either natural (ruminant sources) or industrially generated by partial hydrogenation of vegetable oils. Increasing evidence demonstrated their role as cardiovascular risk factors. Their involvement in cancer etiology is suspected, but epidemiological evidence is limited so far. We aimed to investigate the associations between different types of TFAs (total, ruminant [rTFAs], industrial [iTFAs] and corresponding specific isomers) and the risk of cancer in the NutriNet-Santé prospective cohort (2009-2020). Overall, 104,909 participants were included. Usual TFA intake was estimated from validated repeated 24-h dietary records. Associations between sex-specific quartiles of dietary intake of TFA and cancer risk were assessed using multi-adjusted Cox proportional hazard models. A total of 3,374 incident cancer cases occured during follow-up (including 982 breast and 405 prostate cancers). Total TFAs was associated with higher prostate cancer risk (1.34[1.25;1.87] Ptrend=0.005). rTFAs were associated with increased overall cancer risk (HRfor quartile 4 versus 1: 1.21[1.06;1.39] Ptrend=0.03), in particular the conjugated linoleic acid isomer (CLA) (1.19[1.04;1.36] Ptrend=0.04). These associations were specifically observed for breast cancer, in particular before menopause (rTFAs: 1.78[1.11;2.87] Ptrend=0.006; CLA: 2.013[1.25;3.23] Ptrend=0.003). Several iTFAs were associated with overall (1.18[1.06;1.31] Ptrend=0.02 for transdocosenoic acid), breast (isomer 18:2t: 1.30[1.06;1.58] Ptrend=0.01; hexadecenoic acid: 1.28[1.05-1.56] Ptrend=0.02) and prostate (transdocosenoic acid: 1.52[1.09;2.12] Ptrend=0.07) cancer risks. In this large prospective study, several types of TFAs were associated with increased overall, breast and prostate cancer risks. Although further studies are needed to better understand underlying mechanisms, these results support the WHO's goal of achieving industrially produced TFAs elimination from food supplies.
Key messages
Higher intake of dietary trans fatty acids is associated with an increased risk of various cancers. Our findings support WHO’s global recommendation of eliminating industrially produced TFAs by 2023.

Abstract
Abstract
Nitrates and nitrites occur naturally in water and soil and are commonly ingested from water and dietary sources. They are also frequently used as food additives mainly in processed meats. Experimental data consistently suggest their involvement in carcinogenesis but human data is still limited. The aim was to investigate the relationship between nitrate and nitrite intakes and the risk of cancer in a large prospective cohort with detailed and up-to-date dietary assessment. Overall, 101,056 adults from the French NutriNet-Santé cohort study (2009-ongoing) were included. Consumption of nitrites and nitrates was evaluated using repeated 24h dietary records, linked to a comprehensive food composition database which includes details of commercial names/brands of industrial products. Prospective associations between nitrite and nitrate exposures and the risk of cancer were assessed by multivariable Cox hazard models. During follow-up, 3311 first incident cancer cases were diagnosed. Compared with non-consumers, higher consumers of nitrates as food additives had higher risk of breast cancer (HR = 1.24 (1.03-1.48), P = 0.02); this was more specifically observed for potassium nitrate e252, P = 0.01). Higher consumers of nitrites as food additives, and specifically for sodium nitrite (e250), had a higher risk of prostate cancer (HR = 1.58 (1.14-2.18), P = 0.008 and HR = 1.62 (1.17-2.25), P = 0.004, respectively). No significant association was observed for nitrates and nitrites from natural sources. In this large prospective cohort, nitrates as food additives were positively associated with breast cancer risk and nitrites as food additives were positively associated with prostate cancer risk. While these results need confirmation in other large-scale prospective studies, they provide new insights in a context of lively debate around the ban of nitrite additives in food products.
Key messages
Nitrates as food additives were positively associated with breast cancer risk. Nitrites as food additives were positively associated with prostate cancer risk.

Abstract
Abstract
Background
More than 330 food additives (e.g. artificial sweeteners, emulsifiers, dyes) are authorized in Europe, with a great variability of use across food products. The objective of this study was to investigate the distribution and co-occurrence of food additives in a large-scale database of foods and beverages available on the French market.
Methods
The open access Open Food Facts database was used to retrieve the composition of food and beverage products commonly marketed on the French market (n = 126 556), based on the ingredients list. Clustering of food additive variables was used in order to determine groups of additives frequently co-occurring in food products. The clusters were confirmed by network analysis, using the eLasso method.
Results
53.8% of food products contained at least 1 food additive and 11.3% at least 5. Food categories most likely to contain food additives (in more than 85% of food items) were artificially sweetened beverages, ice creams, industrial sandwiches, biscuits and cakes. The most frequently used food additives were citric acid, lecithins and modified starches (>10,000 products each). Some food additives with suspected health effects also pertained to the top 50: sodium nitrite, potassium nitrate, carrageenan, monosodium glutamate, sulfite ammonia caramel, acesulfame K, sucralose, (di/tri/poly) phosphates, mono- and diglycerides of fatty acids, potassium sorbate, cochineal, potassium metabisulphite, sodium alginate, and bixin (>800 food products each). We identified 6 clusters of food additives frequently co-occurring in food products.
Conclusions
Food additives are widespread in industrial French products and some clusters of additives frequently co-occurring in food products were identified. These results pave the way to future etiological studies merging composition data to food consumption data to investigate their association with chronic disease risk, in particular potential 'cocktail effects'.

Abstract
Abstract
Background
Excessive sugar is now recognized as a key risk factor for several cardiometabolic diseases. In contrast, the associations between sugars and cancer risk in cohort studies have been less investigated, and data is lacking regarding differential effect of sugar types and sources. Experimental data suggest that sugars could play a role in cancer etiology, through obesity but also through inflammatory and oxidative mechanisms and insulin resistance. Our objective was to study the associations between total and added sugar intake and cancer risk, accounting for sugar types and sources.
Methods
101,279 French adults from the NutriNet-Santé prospective cohort study (2009-2019) were included. Sugar intake was assessed using repeated 24h-dietary records, designed to register participants' usual consumption for more than 3,500 food and beverage items. Associations with cancer risk were assessed by multi-adjusted Cox proportional hazard models.
Results
Sugar intake was associated with increased cancer risk (2,503 cases, Hazard Ratio Quartile 4 vs 1=1.17, 95% Confidence Interval 1.00-2.37, P trend=0.02). This association was mainly driven by breast cancer (783 cases, HR Q4 vs Q1=1.51 (1.14-2.00); P trend=0.0007) and remained significant even when weight-gain during follow-up was accounted for. Associations were more specifically observed for added sugars (P trend=0.02), free sugars (P trend=0.007), sucrose (P trend=0.01), and sugars from milk-based desserts (P trend=0.02), from sugary drinks (P trend=0.002), and from dairy products (P trend=0.01).
Conclusions
These results suggest that sugar (especially added sugar), of which intake is increasing in Western countries, may represent a modifiable risk factor for cancer prevention, adding to its well-established effect on dental and cardiometabolic health. These findings provide important and novel insights to the current debate on the implementation of sugar taxation, marketing regulation, and other sugar-related policies.
Key messages
In this large-scale prospective cohort of French adults, sugar intake (especially added sugar) was associated with higher cancer risk. These results suggest that (added) sugar may represent a modifiable risk factor for cancer prevention, adding novel insights to current debates on implementing sugar-related public health policies.

Abstract
Abstract
Background
Cancer remains one of the leading causes of death worldwide. In 2018, following its summary report, the World Cancer Research Fund (WCRF) issued its recommendations for cancer prevention based on the nutritional risk factors with a sufficient level of evidence. Our objective was to study whether adherence to these new recommendations leads to a reduced risk of cancer.
Methods
This study included 80,604 participants from the NutriNet-Santé population-based cohort study (2009-2019). Adherence to the 2018 WCRF recommendations was assessed using the operationalized score on a 7-point scale, proposed by Shams-White et al (Nutrients 2019), including: weight, physical activity, fruit and vegetables, dietary fibers, ultra-processed foods, red and processed meat, sugary drinks and alcohol. Usual dietary intakes were assessed using repeated 24h-dietary records and physical activity level using the IPAQ questionnaire. Multi-adjusted Cox proportional hazard models were used for the analyses.
Results
A total of 2,438 incident cancer cases were diagnosed during follow-up (median: 7.4 years). The median WCRF 2018 adherence score was 3.75 (IQR: 3.25-4.50). An increase of 1-point increment in the score was associated with a decreased risk of cancer overall (HR = 0.90; 95%CI 0.86-0.90; P<.0001), and of obesity-related cancers (n = 1549 cases, HR = 0.89; 0.84-0.94; P<.0001), aerodigestive cancers (n = 390, HR = 0.83; 0.74-0.93; P = 0.001), breast cancer (n = 749, HR = 0.92; 0.85-1.00; P = 0.04) and a non-significant trends for prostate (n = 332, HR = 0.89; 0.79-1.01; P = 0.07) and colorectal (n = 218, HR = 0.88; 0.76-1.03; P = 0.1) cancers.
Conclusions
Our results suggest that a higher adherence to the WCRF 2018 recommendations for cancer prevention is associated to a decreased risk of cancer. Given the consistency between overall food-based dietary guidelines and the WCRF cancer recommendations, our result support their general promotion to the general public and transposition as public health actions.
Key messages
Following the recommendations for cancer prevention issued by the WCRF in 2018 can contribute to decrease the burden of cancer. The WCRF cancer recommendations are consistent with overall food-based dietary guidelines and should be promoted to the general public and transposed as public health actions.

Abstract
Abstract
Background
The past few decades have witnessed a substantial increase in life expectancy in Western countries, leading to an increase in the prevalence of age-related chronic diseases. Several lifestyle risk factors (i.e. smoking, adiposity, unhealthy diet, heavy alcohol drinking and lack of physical activity) have been responsible for a large proportion of premature deaths, as they can affect the incidence of age-related chronic diseases. Our objective was to predict the loss of residual life expectancy (RLE) associated with these lifestyle factors, using data from the EPIC-Heidelberg cohort, linked to an up-to-date mortality registry.
Methods
A total of 23,324 German adults, aged 40 years and above were included (1994-1998) and followed until June 2019. A multi-adjusted parametric proportional hazard model (Gompertz hazard distribution), used to predict survival probabilities, followed by a life table approach was used.
Results
At age 40, being a heavy smoker (> 10 cigarettes/day) was associated with 10.5 y loss of RLE in men and 8.3 in women. Low body mass index (< 22.5 kg/m2) was associated with a RLE loss of 3.7 y in men and 1.4 y in women, while obesity was associated with 4.4 y in men and 3.8 y in women. Heavy alcohol drinking (> 4 drinks/day) was associated with a loss of 4.5 y in men, and high red/processed meat consumption (≥ 120 g/day) was associated with a loss of 1.1y in men and 2.1 y in women. Compared with an overall healthy lifestyle, combined unhealthy behaviors were associated with a loss of RLE of 21.4 y in men and 15.5 y in women.
Conclusions
Prevention strategies encouraging the adoption of an overall healthy lifestyle, particularly by avoiding smoking, heavy alcohol drinking, excess body fatness and reducing red/processed meat consumption, help reducing premature deaths. An extension of this project using blood biomarkers measures is ongoing.
Key messages
Adopting a healthy lifestyle by avoiding or reducing the exposure to risk factors might contribute to a longer life expectancy. Tobacco use, adiposity, and alcohol are probably the main modifiable lifestyle factors affecting life expectancy.

Abstract
Abstract Chlorite dismutase is a unique heme enzyme that catalyzes the conversion of chlorite to chloride and molecular oxygen. The enzyme is highly specific for chlorite but has been known to bind several anionic and neutral ligands to the heme iron. In a pH study, the enzyme changed color from red to green in acetate buffer pH 5.0. The cause of this color change was uncovered using UV–visible and EPR spectroscopy. Chlorite dismutase in the presence of acetate showed a change of the UV–visible spectrum: a redshift and hyperchromicity of the Soret band from 391 to 404 nm and a blueshift of the charge transfer band CT1 from 647 to 626 nm. Equilibrium binding titrations with acetate resulted in a dissociation constant of circa 20 mM at pH 5.0 and 5.8. EPR spectroscopy showed that the acetate bound form of the enzyme remained high spin S = 5/2, however with an apparent change of the rhombicity and line broadening of the spectrum. Mutagenesis of the proximal arginine Arg183 to alanine resulted in the loss of the ability to bind acetate. Acetate was discovered as a novel ligand to chlorite dismutase, with evidence of direct binding to the heme iron. The green color is caused by a blueshift of the CT1 band that is characteristic of the high spin ferric state of the enzyme. Any weak field ligand that binds directly to the heme center may show the red to green color change, as was indeed the case for fluoride. Graphic abstract ![]()

Abstract
Abstract
Previous epidemiological studies found associations between the consumption of ultra-processed foods (UPF) and the risk of obesity-related outcomes. The aim of this study is to investigate the associations between UPF consumption and the risk of overweight and obesity, and weight trajectories, in in the French large scale NutriNet-Santé cohort.
Methods
Overall, 110260 participants aged at least 18 years from the French NutriNet-Santé cohort (2009-2019) were included. Dietary intakes were collected using repeated 24h dietary records, merged with a food composition database of 3300 different products, categorized according to their degree of processing by the NOVA classification. Associations between UPF intake and risks of overweight and obesity were assessed using Cox proportional hazard models. Associations between UPF intake and weight trajectories were assessed using linear mixed models for repeated measures with random slope and intercept.
Results
UPF intake was associated with a higher risk of overweight (n = 7063 incident cases; hazard ratio for an absolute increment of 10 in the percentage of ultra-processed foods in the diet = 1.11 (1.08-1.14); P < 0.0001) and obesity (n = 3066 incident cases; HR = 1.09 (1.05-1.13); P < 0.0001). Higher consumers of UPF (4th quartile) were more likely to present an increase in body mass index over time (β = 0.04, P < 0.0001). These results remained statistically significant after adjustment for several markers of the nutritional quality of the diet (fruits and vegetables and sugary drinks consumption, intakes of saturated fatty acids, sodium, sugar, dietary fiber or Healthy/Western patterns) and after a large range of sensitivity analyses.
Conclusions
In this large observational prospective study, higher consumption of UPF was associated with a higher risk of overweight and obesity. Public health authorities in several countries recently started to recommend privileging unprocessed/minimally processed foods and limiting UPF consumption.
Key messages
The consumption of ultra-processed food is associated with an increased risk of overweight and obesity. As the French Public Helath agency recommends, their consumption should be limited. Nutritional composition, food additives, contact materials, or neoformed contaminants might play a role in these associations and further studies are needed to understand their relative contribution.

Abstract
Abstract
Objective
To assess the prospective associations between consumption of ultra-processed foods (UPF) and the risk of cardiovascular diseases.
Methods
105159 participants aged at least 18 years (median age 41.5 years) from the French NutriNet-Santé cohort (2009-2018) were included. Dietary intakes were collected using repeated 24 hour dietary records, designed to register participants’ usual consumption for 3300 different food items, and categorized according to their degree of processing by the NOVA classification. Associations between UPF intake and risk of cardiovascular, coronary heart, and cerebrovascular diseases assessed by multivariable Cox proportional hazard models, adjusted for known risk factors.
Results
UPF intake was associated with higher cardiovascular disease risk (n = 1409 cases; HR for an absolute increment of 10 in the percentage of UPF = 1.12(1.05-1.20); P = 0.0008), coronary heart disease risk (n = 665 cases; HR = 1.13(1.02-1.24); P = 0.02), and cerebrovascular disease risk (n = 829 cases; HR = 1.11(1.01-1.22); P = 0.02). These results remained statistically significant after adjustment for several markers of the nutritional quality of the diet (saturated fatty acids, sodium and sugar intakes, dietary fiber or a Healthy pattern derived by principal component analysis) and after a large range of sensitivity analyses.
Conclusions
In this large observational prospective study, higher consumption of UPF was associated with higher risks of cardiovascular, coronary heart, and cerebrovascular diseases. These results need to be confirmed in other populations and settings, and causality remains to be established.
Key messages
The consumption of ultra-processed food is associated with an increased risk of cardiovascular diseases. As the French Public Helath agency recommends, their consumption should be limited. Nutritional composition, food additives, contact materials, or neoformed contaminants might play a role in these associations and further studies are needed to understand their relative contribution.

Abstract
Abstract
Background
The objective was to assess the associations between the consumption of sugary drinks (sugar sweetened beverages and 100% fruit juices), artificially sweetened beverages and cancer risk.
Methods
Overall, 101,257 participants aged ≥18y (mean age: 42.2) from the French NutriNet-Santé cohort (2009-2017) were included. Consumptions of sugary drinks and artificially sweetened beverages were assessed using repeated 24h-dietary records, designed to register participants’ usual consumption for 3,300 different food and beverage items. Associations between beverage consumption and the risk of overall, breast, prostate and colorectal cancer were assessed by multi-adjusted Fine&Gray Hazard models, accounting for competing risks.
Results
The consumption of sugary drinks was significantly associated with overall cancer risk (n = 2,193 cases, sHRfor a 100mL/d increase=1.18, 95% confidence interval 1.10 to 1.27, P<.0001) and breast cancer risk (n = 693 cases, sHRfor a 100mL/d increase=1.22, 95% confidence interval 1.07 to 1.39, P = 0.004). The consumption of artificially sweetened beverages was not associated with cancer risk. In specific sub-analyses, the consumption of 100% fruit juice was significantly associated with overall cancer risk (n = 2,193 cases, sHRfor a 100mL/d increase =1.12, 95% confidence interval 1.03 to 1.23, P = 0.007).
Conclusions
In this large prospective study, the consumption of sugary drinks was positively associated with overall and breast cancer risks. Of note, 100% fruit juices were also positively associated with overall cancer risk. These results need replication in other large-scale prospective studies. They suggest that sugary drinks, which are massively consumed in Western countries, may potentially represent a modifiable risk factor for cancer prevention.
Key messages
In this large prospective study (n = 101,257), the consumption of sugary drinks (including 100% fruit juice) was associated with an increase in overall and breast cancer risk. In specific sub-analyses, 100% fruit juices were also associated with an increased risk of overall cancers. The consumption of artificially sweetened beverages was not associated with cancer risk.

Abstract
Abstract
Background
Unhealthy diets are major contributors for non-communicable diseases (NCDs) and related deaths. To help consumers make healthier food choices, political authorities are considering implementing a simple label to reflect the nutritional quality of food products. The Nutri-Score, based on the nutrient profiling system of the Food Standards Agency (FSAm-NPS), was chosen by several countries in Europe (France, Belgium, Spain). Yet, its implementation is only voluntary per EU regulation. Scientific evidence is therefore needed regarding the relevance of the FSAm-NPS at the European level. Hence, our objective is to study how the nutritional quality of foods consumed graded by the FSAm-NPS relates to NCDs-related mortality in European populations.
Methods
Our prospective analyses included 501,594 adults from the EPIC cohort (1992-2015, median follow-up: 17.2y). Usual food intakes were assessed with standardized country-specific methods. The FSAm-NPS was calculated using the 100g content of each food in energy, sugar, saturated fatty acid, sodium, fibres, proteins, and fruits/vegetables/legumes/nuts. Multi-adjusted Cox proportional hazards models were computed.
Results
The consumption of foods with a higher FSAm-NPS score (lower nutritional quality) was associated with a higher risk of mortality overall (n = 50,743 events: HRQ5vs.Q1=1.06 [95%CI: 1.02-1.09], P-trend<0.001) and by cancer (n = 21,971 events: HRQ5vs.Q1=1.06 [1.01-1.11], P-trend=0.003), respiratory diseases (n = 2,796 events: HRQ5vs.Q1=1.33 [1.16-1.52], P-trend<0.001) and cardiovascular diseases, although more weakly (n = 12,407 events: HRQ5vs.Q1=1.05 [0.98,1.11], P-trend=0.04).
Conclusions
In this large multinational European cohort, consuming foods with a higher FSAm-NPS score was associated with higher mortality, supporting the relevance of the FSAm-NPS to grade the nutritional quality of food products for public health applications (e.g, Nutri-Score) to guide the consumers towards healthier food choices.
Key messages
The consumption of food products with a lower nutritional quality as graded by the FSAm-NPS score was associated with higher mortality in the large multinational European EPIC cohort. This adds support to the relevance of the FSAm-NPS to grade the nutritional quality of foodstuffs for public health applications (e.g. Nutri-Score label) to help consumers make healthier food choices.

Abstract
Abstract
Objective
The consumption of ultra-processed foods has been increasing during the last decades, and has been previously associated with increased risks of mortality and several chronic diseases. The objective of this study is to assess for the first time the prospective associations between consumption of ultra-processed foods and the risk of type 2 diabetes (T2D).
Methods
104707 participants aged at least 18 years (median age 41.5 years) from the French NutriNet-Santé cohort (2009-2019). Dietary intakes were collected using repeated 24 hour dietary records, designed to register participants’ usual consumption for 3300 different food items, categorized according to their degree of processing by the NOVA classification. Associations between ultra-processed food intake and risk of T2D were assessed using multi-adjusted Cox proportional hazard models.
Results
Ultra-processed sugary products, fruits and vegetables, and beverages were the highest contributors of the ultra-processed category (respectively 27.9, 18.5 and 15.6%). Ultra-processed food intake was associated with a higher risk of T2D (n = 821 incident cases; hazard ratio for an absolute increment of 10 in the percentage of ultra-processed foods in the diet = 1.15 (1.06-1.25); P = 0.0009, 582252 person-years). These results remained statistically significant after adjustment for other metabolic comorbidities, for several markers of the nutritional quality of the diet (red meat and sugary drinks consumption, intakes of saturated fatty acids, sodium, sugar, dietary fiber or Healthy/Western patterns derived by principal component analysis) and after a large range of sensitivity analyses.
Conclusions
In this large observational prospective study, higher consumption of ultra-processed foods in the diet was associated with a higher risk of T2D. Public health authorities in several countries recently started to recommend privileging unprocessed/minimally processed foods and limiting ultra-processed food consumption.
Key messages
The consumption of ultra-processed food is associated with an increased risk of type 2 diabetes. As the French Public Helath agency recommends, their consumption should be limited. Nutritional composition, food additives, contact materials, or neoformed contaminants might play a role in these associations and further studies are needed to understand their relative contribution.

Abstract
Abstract
OBJECTIVE
To assess the associations between the consumption of sugar-containing and artificially sweetened beverages and cancer risk.
DESIGN
Population based prospective cohort study.
SETTING AND PARTICIPANTS
Overall, 101 257 participants aged ≥18y (mean age: 42.2±14.4y) from the French NutriNet-Santé cohort (2009-2017) were included. Consumptions of sugar-containing and artificially sweetened beverages were assessed using repeated 24h-dietary records, designed to register participants' usual consumption for 3300 different food and beverage items.
MAIN OUTCOME MEASURES
Associations between beverage consumption and overall, breast, prostate and colorectal cancer risk were assessed by multivariable Cox Proportional Hazard models adjusted for known risk factors.
RESULTS
A 100mL increase in the consumption of sugar-containing beverages was significantly associated with an increased risk of overall cancer (HR=1.08, 95% confidence interval 1.04 to 1.12, P<.0001) and breast cancer (HR=1.11, 95% confidence interval 1.04 to 1.19, P<0.002). The consumption of artificially sweetened beverages was not associated with cancer risk. In sub-analyses, a 100 mL increase in the consumption of 100% fruit juice was significantly associated with an increased risk of overall cancers (HR=1.08, 95% confidence interval 1.02 to 1.15, P=0.01). These associations were strongly mediated by the sugar contained in these beverages. In contrast, weight gain during follow-up did not appear as a strong mediator. Besides, results were similar in overweight and non-overweight participants.
CONCLUSIONS
In this large prospective study, a 100mL increase in the consumption of sugar-containing beverages in the diet was associated with an 8% significant increase in overall cancer risk and an 11% significant increase in breast cancer risk. 100% fruit juices were also associated with an 8% increased risk of overall cancers. Given the massive consumption of sugar-containing beverages in Western countries, these results suggest that they may represent a key modifiable risk factor for cancer prevention.

Abstract
Abstract
Background: While many cancer patients are affected by weight loss, others tend to gain weight, which may impact prognosis and risk of recurrence and of second cancer. The aim of this prospective study was to investigate weight variation between before and after cancer diagnosis and socio-demographic, economic, lifestyle and clinical factors associated with moderate-to-severe weight gain.
Methods: 1051 incident cases of first primary cancer were diagnosed in the NutriNet-Santé cohort between 2009 and 2015. Weight was prospectively collected every 6 months since subjects' inclusion (i.e. an average of 2y before diagnosis). Mean weights before and after cancer diagnosis were compared with paired Student's t-test. Factors associated with moderate-to-severe weight gain (≥5% of initial weight) were investigated by multivariable logistic regression.
Results: Weight loss was observed in men (-3.54kg in those who lost weight, p=0.0002) and in colorectal cancer patients (-3.94kg, p=0.0012). Weight gain was observed in breast and skin cancers (2.83kg, p=0.047, and 2.96kg, p=0.03 respectively). Women (OR=1.99[1.18-3.35]), younger patients (OR=1.78[1.05-3.03]), those with lower education (OR=2.17[1.07-4.37]), those with excess weight before diagnosis (OR=1.53[1.02-2.30]) and those who stopped smoking after diagnosis (OR=4.60[2.06-10.25]) were more likely to experience moderate-to-severe weight gain. In breast cancer patients, induced menopause was associated with weight gain (OR=4.12[1.76-9.67]), but no association was detected for tumor characteristics or treatments.
Conclusion: This large prospective cohort provided original results on weight variation between before and after cancer diagnosis, highlighting different weight trajectories. Socio-demographic and economic factors appeared to strongly influence the risk of weight gain, illustrating social inequalities in health.

Abstract
Specialized infrared spectroscopic techniques have been developed that allow studying the secondary structure of membrane proteins and the influence of crucial parameters like lipid content and detergent. Here, we focus on an ATR-FTIR spectroscopic study of Af-Amt1 and the influence of LDAO/glycerol on its structural integrity. Our results clearly indicate that infrared spectroscopy can be used to identify the adapted sample conditions.
