Ultra-processed food consumption patterns among older adults in the Netherlands and the role of the food environment

Quality of nutritional uptake of community-dwelling, care-dependent older adults in Zurich

OBJECTIVE

This study evaluated the quality of nutritional uptake of the care-dependent, community-dwelling older adults.

METHODS

Community-dwelling care-dependent elders were recruited in this study. The food items along with their nutritional content were extracted from the participants' refrigerators and categorized according to the NOVA classification (G1: unprocessed/minimally processed; G2: processed culinary ingredients; G3: processed; G4: ultra-processed). The nutritional information of the food items was entered into a dietary analysis software that analyzed the content. Data was verified for a normal distribution and non-parametric tests were applied for statistical analysis (p < 0.05).

RESULTS

100 subjects (mean age = 81.1±9.5 y; mean MMSE: 26.6±6.8) participated in this study. The participants had significantly more G1 than G2, G3 or G4 (p < 0.001) foods. Women had more G1 items in their refrigerators than men (rs = 0.372, p < 0.001). Higher socio-economic status indicated a presence of more G1 (rs = 0.313, p = 0.002), G2 (rs = 0.342, p < 0.001) and G4 (rs = 0.237, p = 0.024) foods. Higher cognitive scores revealed an increase in presence of G4 (rs = 0.238, p = 0.023) items. Participants with an increased need for assistance had less G2 (rs = -0.332, p = 0.001), and G4 (rs = -0.215, p = 0.041) foods; age had no influence.

CONCLUSION

The findings of this study confirm that the majority of care-dependent, community-dwelling adults procured healthy dietary aliments for their daily living; however, whether this correlated to the actual nutritional state of these older adults needs to be further investigated. This highlights the need for further investigation and tailored interventions to ensure good nutrition, emphasizing regular assessments and comprehensive support beyond just food access.

CLINICAL RELEVANCE

Clinicians must recognize that access to healthy food alone may not ensure good nutrition in older adults. Regular nutritional assessments, personalized dietary interventions, and additional support services like meal preparation assistance, nutritional counseling, and tailored programs are essential to address specific dietary needs and preferences.

The role of ultra-processed foods in plant-based diets: associations with human health and environmental sustainability

PURPOSE

Investigate the associations of ultra-processed foods (UPF) in healthful (hPDI) and unhealthful (uPDI) plant-based diets with all-cause mortality, greenhouse gas emissions (GHGE), and blue water consumption (BWC).

METHODS

Analyses were based on 35,030 participants (20-70 years; 74% females) from the EPIC-NL cohort who were followed up from 1993 to 1997 through 2014. Plant-based diet indices (hPDI and uPDI) and UPF consumption were calculated from a validated FFQ, assessed at baseline. Cox proportional hazard and multiple linear regression models were used to estimate associations between combined quartiles of the PDI indices and UPF consumption.

RESULTS

With lower hPDI and higher UPF diets as the reference, we observed the following. Risk estimates of all-cause mortality were 0.98 (95% CI: 0.83, 1.16) for lower UPF consumption, 0.86 (95% CI: 0.68, 1.08) for higher hPDI, and 0.78 (95% CI: 0.66, 0.89) for combined higher hPDI and lower UPF consumption. Results with the uPDI were inconclusive. Mean differences in GHGE and BWC were 1.4% (95% CI: 0.3, 2.4) and 1.6% (95% CI: -0.5, 3.7) for lower UPF consumption, -7.4% (95% CI: -8.6, -6.4) and 9.6% (95% CI: 7.2, 12.0) for higher hPDI, and - 6.8% (95% CI: -7.4, -6.1) and 13.1% (95% CI: 11.6, 14.8) for combined higher hPDI and lower UPF consumption. No apparent conflict between environmental impacts was observed for the uPDI; GHGE and BWC were lower for higher uPDI scores.

CONCLUSION

Mortality risk and environmental impacts were mostly associated with the amount of plant-based foods and to a lesser extent UPF in the diet. Shifting to a more healthful plant-based diet could improve human health and reduce most aspects of environmental impact (GHGE, but not BWC) irrespective of UPF consumption.

The association of highly processed food consumption with food choice values and food literacy in Japanese adults: a nationwide cross-sectional study

BACKGROUND

Highly processed food (HPF) consumption is increasing globally and has become a prominent public health concern. However, the relationship between HPF consumption and food choice values and food literacy is unknown. This study aimed to examine the association of HPF consumption with food choice values and food literacy.

METHODS

This cross-sectional study used data from a nationwide questionnaire survey conducted in 2018 among 2232 Japanese adults aged 18-80 years. We assessed eight food choice values (accessibility, convenience, health/weight control, tradition, sensory appeal, organic, comfort, and safety) using a 25-item scale, and food literacy characterised by nutrition knowledge (using a validated 143-item questionnaire), cooking and food skills (using 14- and 19-item scales, respectively), and eight eating behaviours (hunger, food responsiveness, emotional overeating, enjoyment of food, satiety responsiveness, emotional undereating, food fussiness, and slowness in eating, using the 35-item Adult Eating Behavior Questionnaire). HPF consumption was estimated using a validated brief diet history questionnaire. The associations between HPF consumption and age, body mass index, energy intake, and each score on food choice values and food literacy were evaluated by multiple linear regression.

RESULTS

In males, one standard deviation increase in scores for cooking skill and satiety responsiveness was associated with an increase in HPF consumption by 22.1 g/4184 kJ (95% confidence interval (CI): 6.6 to 37.5) and 15.4 g/4184 kJ (95% CI: 6.0 to 24.7), respectively. In females, one standard deviation increase in age and scores for safety and nutrition knowledge corresponded to a decrease in HPF consumption by - 16.4 g/4184 kJ (95% CI: - 23.4 to - 9.3), - 9.9 g/4184 kJ (95% CI: - 19.1 to - 0.7), and - 11.1 g/4184 kJ (95% CI: - 17.0 to - 5.3), whereas one standard deviation increase in the satiety responsiveness score corresponded to an increase in HPF consumption by 13.1 g/4184 kJ (95% CI: 6.8 to 19.4).

CONCLUSIONS

This cross-sectional study suggests that several aspects of food choice values and food literacy were associated with HPF consumption in Japanese adults. Further studies are needed to confirm our findings in a broader context.

Local Food Environment and Consumption of Ultra-Processed Foods: Cross-Sectional Data from the Nutritionists' Health Study-NutriHS

This study aimed to analyze whether community food environments are associated with individual food consumption among nutrition students and newly graduated nutritionists. This cross-sectional study used data from the Nutritionists' Health Study cohort, which included 357 undergraduate nutrition students from the city of Fortaleza, Ceará, Brazil. Exposure to the food environment was defined as the proximity and availability of food outlets within a 500 m buffer from the participants' homes. Food consumption was assessed using a Food Frequency Questionnaire and analyzed according to the NOVA classification. Multi-level linear regression models with fixed effects were used to estimate the presence of food outlets within the buffer and their association with food consumption. The presence of mini-markets in the buffer in the fourth quartile was associated with lower consumption of ultra-processed foods (UPF) when observing socioeconomic and lifestyle conditions (β = -3.29; 95% CI = -6.39 to -0.19). The presence of bakeries and coffee shops was related to lower consumption of ultra-processed foods among participants when observing socioeconomic conditions (β = -3.10; 95% CI = -6.18 to -0.02). There was no clear evidence of an association between the type of food outlet and UPF consumption. The community food environment seemed to influence food consumption among study participants, although clearer and more consistent evidence on this subject is needed.

Different levels of ultra-processed food and beverage consumption and associations with environmental sustainability and all-cause mortality in EPIC-NL

BACKGROUND

The adverse health effects of high ultra-processed food and drink consumption (UPFD) are well documented. However, its environmental impact remains unclear and the separate effects of ultra-processed foods (UPF) and drinks (UPD) on all-cause mortality are not previously studied.

OBJECTIVES

To assess the association between levels of UPFD, UPF and UPD consumption with diet-related environmental impacts and all-cause mortality in Dutch adults.

METHODS

Habitual diets were assessed by FFQ in 1993-1997 among 38,261 participants of the EPIC-NL cohort. The mean follow-up time was 18.2 years (SD 4.1), 4,697 deaths occurred. FFQ-items were categorized according to the NOVA classification. Associations with quartiles of UPFD, UPF, and UPD consumption and environmental impact indicators were analyzed using general linear models and with all-cause mortality by Cox proportional hazard models. The lowest UPFD, UPF, UPD consumption quartiles were used as comparator.

RESULTS

The average UPFD consumption was 181 (SD 88) g per 1000 kcal. High UPF consumption was statistically significantly inversely associated with all environmental impact indicators (_Q4vsQ1: -13.6% to -3.0%) whereas high UPD consumption was, except for land use, statistically significant positively associated with all environmental impact indicators (_Q4vsQ1: 5.9% to 1.2%). High UPFD consumption was heterogeneously associated with environmental impacts (_Q4vsQ1: 2.6% to -4.0% ). After multivariable adjustment, the highest quartiles of UPFD and UPD consumption were significantly associated with all-cause mortality (HR_Q4vsQ1 1.20, 95%CI 1.10,1.30 and HR_Q4vsQ1 1.19, 95%CI 1.09,1.29, respectively). UPF consumption of Q2 and Q3 were associated with a borderline significant lower risk of all-cause mortality (HR_Q2vsQ1 0.93, 95% CI 0.85,1.00; HR_Q3vsQ1 0.91, 95% CI 0.84,0.99), while Q4 was not statistically significant (HR_Q4vsQ1 1.05, 95% CI 0.96,1.15).

CONCLUSIONS

Reducing UPD consumption could lower environmental impact and all-cause mortality risk, however this was not shown for UPF. When categorizing foods consumption by their degree of processing trade-offs are observed for human and planetary health aspects.

Survey-derived activity space-based exposures to fast food outlets and their cross-sectional associations with use of fast food outlets, diet quality and BMI

There is a need for conceptual and methodological innovation in food environment-health research. We compared different operationalizations of survey-derived activity space exposures to fast food outlets (FFOs) in associations with use of FFO, diet quality and body mass index (BMI). FFO exposure was determined for home, work and a maximum of sixteen other locations reported by 1728 Dutch adults. Considerable differences in count of FFO between locations were found. Adjusted linear regression analyses resulted in small, unexpected associations with use of FFO, diet quality and BMI, whereby the strength of associations differed between exposure measures. Using home and work areas may be a cost-efficient compromise to capture large parts of the exposure to FFOs.

An Analysis of the Contributors and Factors Influencing Dietary Patterns Among the Elderly Population

The normal process of aging consists of numerous behavioral, social, physical, psychological, and socioeconomic factors which may negatively affect the nutritional status of a senior. Old people are susceptible to poor nutritional status as they are mostly affected by nutritional deficiencies compared to individuals that belong to other age groups. The poor dietary pattern among the elderly leads to chronic diseases such as coronary heart disease, atherosclerosis, type 2 diabetes, hypertension, or malnutrition. Factors such as socioeconomic indicators, price of food items, marital status, psychological factors, changes in sensory functioning, access to food commodities, nutrition knowledge and cooking skills, gastrointestinal problems, oral health, and medication factors may influence the dietary pattern of an elderly individual. This review focuses on the factors affecting the eating habits of the elderly.

The longitudinal associations between proximity to local grocery shops and functional ability in the very old living with and without multimorbidity: Results from the Newcastle 85+ study

BACKGROUNDS

The very old, people aged ≥85, is a fast-growing age group with high risk of disability and dependence. To identify environmental factors that support maintenance of functional ability, the aim of this study is to investigate the longitudinal associations between proximity to local grocery shops and the ability to shop for groceries in the very old and to examine the potential variation between those living with and without multimorbidity.

METHODS

This study was based on the Newcastle 85+ study, a population-based cohort of people aged 85 in North-East England. The numbers of grocery shops were identified within a 500 m road distance to participants' residence. Multilevel Poisson regression modelling was used to investigate whether proximity to local grocery shops was associated with the ability to do grocery shopping over five years in those with and without multimorbidity adjusting for sociodemographic factors and area deprivation.

RESULTS

The very old who lived in more deprived areas were more likely to have a grocery shop within 500 m than those in less deprived areas. Proximity to local grocery shops was not associated with the ability to do grocery shopping in the participants who had none or one chronic condition (IRR: 1.00; 95% CI: 0.89, 1.12) but moderated loss of the ability in those living with multimorbidity (IRR: 0.82; 95% CI: 0.70, 0.96).

CONCLUSIONS

For the very old living with multimorbidity, proximity to local grocery shops may support their functional ability. Future research should investigate how to support older people with poor health to access local grocery shops.

A ciência da Nutrição no “Novo Regime Climático”

Uma das maiores preocupações da humanidade no momento atual, denominado por Bruno Latour de um “Novo Regime Climático, é o impacto negativo produzido pelas mudanças ambientais, uma vez que seus efeitos repercutem em todo o planeta. A deterioração do meio ambiente natural tem sido acompanhada de um correspondente aumento dos problemas de saúde dos indivíduos. Nos encontramos numa fase de crise de paradigma na Ciência da Nutrição, em que a mudança se torna cada vez mais necessária e urgente; o caminho que vem sendo apontado é o da ampliação das noções existentes rumo a uma visão sistêmica e holística para enfrentar os desafios e oportunidades do século XXI. Este ensaio reflexivo teórico tem como base a obra de Bruno Latour, e tem como objetivo identificar as intersecções da Ciência da Nutrição e o exercício profissional do nutricionista com a ideia da reorientação ao vetor que Latour chama de “Terrestre”, como novo ator-político no período do Antropoceno. Torna-se necessário estender o mandato da prática baseada em evidências para adotar modelos mais relacionais de pensamento crítico para a aprendizagem transformacional em nutrição, sendo uma oportunidade de colaboração para todos os profissionais da área apoiarem as pessoas a combinarem uma alimentação saudável com uma alimentação sustentável. O redirecionamento da ciência da Nutrição vai ao encontro das ideias recentes de Latour em relação a uma possível mudança do sistema de produção para o sistema de geração sintonizado com a sustentabilidade

Ultraprocessed food consumption and kidney function decline in a population-based cohort in the Netherlands

BACKGROUND

Ultraprocessing makes food products more convenient, appealing, and profitable. Recent studies show that high ultraprocessed food (UPF) intake is associated with cardiometabolic diseases.

OBJECTIVES

The aim of this study is to investigate the association between UPF consumption and risks of kidney function decline in the general population.

METHODS

In a prospective, general population-based Lifelines cohort from Northern Netherlands, 78,346 participants free of chronic kidney disease (CKD) at baseline responded to a 110-item FFQ. We used a multivariable regression analysis to study the associations of the proportion (in grams/day) of UPFs in the total diet with a composite kidney outcome [incident CKD or a ≥30% estimated glomerular filtration rate (eGFR) decline relative to baseline] and annual change in eGFR.

RESULTS

On average, 37.7% of total food intake came from UPFs. After 3.6 ± 0.9 years of follow-up, 2470 participants (3.2%) reached the composite kidney outcome. Participants in the highest quartile of UPF consumption were associated with a higher risk of the composite kidney outcome (OR, 1.27; 95% CI, 1.09-1.47; P = 0.003) compared with those in the lowest quartile, regardless of their macro- or micronutrient intake or diet quality. Participants in the highest quartile had a more rapid eGFR decline (β, -0.17; 95% CI, -0.23 to -0.11; P < 0.001) compared with those in the lowest quartile. Associations were generally consistent across different subgroups.

CONCLUSIONS

Higher UPF consumption was associated with a higher risk of a composite kidney outcome (incident CKD or ≥30% eGFR decline) and a more rapid eGFR decline in the general population, independent of confounders and other dietary indices.

A Systematic Review of Worldwide Consumption of Ultra-Processed Foods: Findings and Criticisms

A debate is ongoing on the significance and appropriateness of the NOVA classification as a tool for categorizing foods based on their degree of processing. As such, the role of ultra-processed food (UPF) on human health is still not completely understood. With this review, we aimed to investigate the actual level of consumption of UPF across countries and target populations to determine the impact in real contexts. Suitable articles published up to March 2021 were sourced through the PubMed and SCOPUS databases. Overall, 99 studies providing data on the level of UPF consumption expressed as the percentage of total energy intake were identified, for a total of 1,378,454 participants. Most of them were published in Brazil (n = 38) and the United States (n = 15), and the 24 h recall was the most-used tool (n = 63). Analysis of the results revealed that the United States and the United Kingdom were the countries with the highest percent energy intake from UPF (generally >50%), whereas Italy had the lowest levels (about 10%); the latter was inversely associated with adherence to the Mediterranean diet. High variability was also observed based on sex, age, and body mass index, with men, young people, and overweight/obese subjects generally having higher levels of consumption compared to older subjects. Overall, our findings underline the large differences in UPF intake. Since most of the observations derived from studies conducted with food questionnaires are not specifically validated for UPF, further efforts are essential to confirm the results previously obtained and to investigate further the association between UPF consumption and health status, also considering the actual contribution within different dietary patterns, which has been less investigated to date.
