Association Between Ultra-Processed Food Intake and All-Cause Mortality: A Systematic Review and Meta-Analysis. Am J Epidemiol 2022; 191:1323-1335. [PMID: 35231930 DOI: 10.1093/aje/kwac039] [Citation(s) in RCA: 46] [Impact Index Per Article: 23.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2021] [Revised: 02/07/2022] [Accepted: 02/25/2022] [Indexed: 01/26/2023] Open
Abstract
Consumption of ultra-processed foods (UPF) has increased worldwide during the last decades because they are hyperpalatable, cheap, and ready-to-consume products. However, uncertainty exists about their impact on health. We conducted a systematic review and meta-analysis evaluating the association of UPF consumption with all-cause mortality risk. Five bibliographic databases were searched for relevant studies. Random effects models were used to calculate pooled relative risks (RRs) and 95% confidence intervals (CIs). Of 6,951 unique citations, 40 unique prospective cohort studies comprising 5,750,133 individuals were included; publication dates ranged from 1984 to 2021. Compared with low consumption, highest consumption of UPF (RR = 1.29, 95% CI: 1.17, 1.42), sugar-sweetened beverages (RR = 1.11, 95% CI, 1.04, 1.18), artificially sweetened beverages (RR = 1.14, 95% CI, 1.05, 1.22), and processed meat/red meat (RR = 1.15, 95% CI, 1.10, 1.21) were significantly associated with increased risk of mortality. However, breakfast cereals were associated with a lower mortality risk (RR = 0.85, 95% CI, 0.79, 0.92). This meta-analysis suggests that high consumption of UPF, sugar-sweetened beverages, artificially sweetened beverages, processed meat, and processed red meat might increase all-cause mortality, while breakfast cereals might decrease it. Future studies are needed to address lack of standardized methods in UPF categorization.

Abstract
This study investigates the extent to which aspects of the social integration of the elderly are linked to higher levels of fruit and vegetable consumption. It involved a cross-sectional study based on data from the National Study of Dependency in the Elderly, with a sample of 3278 elderly individuals. The variables of social integration considered were: frequency of meeting with close relatives, other relatives and neighbors and friends in the last 12 months; participation in recreational activities and in community groups, in addition to housing arrangements and marital status. The number of servings of fruit and vegetables consumed per day was the dependent variable. Logistic regression analysis was then conducted. In the adjusted model, more frequent encounters with siblings, in-laws and nephews, participation in community groups or organizations, are factors that increase the possibility of consuming two or more servings of fruit and vegetables a day, versus 1 serving or none; the opposite was observed when living alone. The variables of social integration that can increase the possibility of attaining the recommendation of consumption of fruit and vegetables daily (5 or more) in the adjusted model are frequency of encounters with siblings, in-laws and nephews and living alone.

Abstract
PURPOSE We aimed to synthesize the evidence on the relation between different types of potato consumption with risk of all-cause mortality, coronary heart disease (CHD), stroke, type 2 diabetes (T2D), colorectal cancer (CRC), and hypertension. METHODS Systematic searches until May 2018 were conducted in PubMed, Scopus, and Web of Science. Random effects meta-analyses comparing extreme categories, linear and non-linear dose-response analyses were conducted. RESULTS Twenty-eight reports were identified. Only total potato consumption was available for some endpoints which showed no associations with all-cause mortality (RR: 0.88, 95% CI 0.69-1.12), CHD (RR: 1.03, 95% CI 0.96-1.09), stroke (RR: 0.98, 95% CI 0.93-1.03), and CRC (RR: 1.05, 95% CI 0.92-1.20) per one daily/serving (150 g/day) increase. Consumption of one daily serving of boiled/baked/mashed-potatoes was not associated with risk of hypertension (RR: 1.08, 95% CI 0.96-1.21), but slightly with the risk of T2D (RR: 1.09, 95% 1.01-1.18). Positive associations for the risk of T2D (RR: 1.66, 95% CI 1.43-1.94) and hypertension (RR: 1.37, 95% CI 1.15-1.63) were observed for each 150 g/day increase in French-fries consumption. The quality of evidence was rated mostly low (moderate quality of evidence for the risk-associations of French-fries). CONCLUSION Total potato consumption is not related to risk for many chronic diseases but could pose a small increase in risk for T2D if consumed boiled. A clear risk relation was found between French-fries consumption and risk of T2D and hypertension. For several outcomes, the impact of different preparation procedures could not be assessed.

Abstract
A systematic review and meta-analysis of prospective cohort studies was conducted to examine the association of potato consumption and risk of all-cause, cancer and cardiovascular mortality in adults. We searched PubMed, Scopus databases up to September 2018 for all relevant published papers. All analyses were performed on HRs or RRs and 95% CIs. In twenty prospective studies, 25,208 cases were reported for all-cause mortality, 4877 for cancer mortality and 2366 for CVD mortality. No significant association was found between potato consumption and risk of all-cause (0.90; 95% CI: 0.8, 1.02, p = 0.096) and cancer (1.09; 95% CI: 0.96, 1.24, P = 0.204) mortality. In addition, no significant linear association was found between each 100 g/d increments in potato consumption and risk of all-cause (P = 0.7) and cancer (P = 0.09) mortality. Moreover, nonlinear association between potato consumption and risk of cancer mortality was non-significant (P-nonlinearity = 0.99). In addition, two of three studies which examined the association of potato consumption with CVD mortality did not find any significant relationship. There was no evidence for publication bias in this study. We failed to find significant association between potato consumption and risk of mortality. Further studies are required to confirm this issue.

Abstract
KEY POINTS Sudden infant death syndrome (SIDS) is one of the leading causes of death during the first year of life and abnormalities linked to serotonin (5-HT) have been identified in many SIDS cases. Cigarette smoking and associated exogenous stressors, e.g. developmental nicotine exposure, may compound these serotonergic defects and any associated defects in cardiorespiratory function. Using neonatal rodent pups subjected to medullary 5-HT deficiency and perinatal nicotine exposure, we examined the impact of this interplay of factors on the neonates' ability to autoresuscitate at specific ages. In perinatal nicotine-exposed 5-HT deficient pups, impaired autoresuscitation along with significantly delayed post-anoxic recovery of normal breathing and heart rate was observed at postnatal day 10 (P10). We found that the interaction between 5-HT deficiency and perinatal nicotine exposure can significantly increase pups' vulnerability to environmental stressors and exacerbate defects in cardiorespiratory protective reflexes to repetitive anoxia during the development period. ABSTRACT Cigarette smoking during pregnancy increases the risk of sudden infant death syndrome (SIDS), and nicotine replacements, a key ingredient of cigarettes, have been recently prescribed to women who wish to quit smoking during their pregnancy. Serotonin (5-HT) abnormalities have been consistently identified in many SIDS cases. Here we investigated the effects of perinatal nicotine exposure in mild 5-HT deficiency rat neonates on autoresuscitation, a protective cardiorespiratory reflex. The mild 5-HT deficiency was induced by a maternal tryptophan-deficient diet, and nicotine was delivered from embryonic day (E) 4 to postnatal day (P) 10 at 6 mg kg-1 day-1 through an osmotic pump. In P10 rats, nicotine exposure exacerbates autoresuscitation failure (mortality) in mildly 5-HT-deficient rats to a greater extent than in controls (P = 0.029). The recovery of eupnoea and heart rate to baseline values following repetitive anoxic events (which elicit an apnoea accompanied by a bradycardia) is significantly delayed in 5-HT-deficient rats treated with nicotine, making them more susceptible to failure of autoresuscitation (eupnoea recovery: P = 0.0053; heart rate recovery: P = < 0.0001). Neither 5-HT deficiency nor nicotine exposure alone appears to affect the ability to autoresuscitate significantly when compared among the four treatments. The increased vulnerability to environmental stressors, e.g. severe hypoxia, asphyxia, or anoxia, in these nicotine-exposed 5-HT-deficient neonates during postnatal developmental period is evident.

Abstract
Background Questions remain about the strength and shape of the dose-response relationship between fruit and vegetable intake and risk of cardiovascular disease, cancer and mortality, and the effects of specific types of fruit and vegetables. We conducted a systematic review and meta-analysis to clarify these associations. Methods PubMed and Embase were searched up to 29 September 2016. Prospective studies of fruit and vegetable intake and cardiovascular disease, total cancer and all-cause mortality were included. Summary relative risks (RRs) were calculated using a random effects model, and the mortality burden globally was estimated; 95 studies (142 publications) were included. Results For fruits and vegetables combined, the summary RR per 200 g/day was 0.92 [95% confidence interval (CI): 0.90-0.94, I 2 = 0%, n = 15] for coronary heart disease, 0.84 (95% CI: 0.76-0.92, I 2 = 73%, n = 10) for stroke, 0.92 (95% CI: 0.90-0.95, I 2 = 31%, n = 13) for cardiovascular disease, 0.97 (95% CI: 0.95-0.99, I 2 = 49%, n = 12) for total cancer and 0.90 (95% CI: 0.87-0.93, I 2 = 83%, n = 15) for all-cause mortality. Similar associations were observed for fruits and vegetables separately. Reductions in risk were observed up to 800 g/day for all outcomes except cancer (600 g/day). Inverse associations were observed between the intake of apples and pears, citrus fruits, green leafy vegetables, cruciferous vegetables, and salads and cardiovascular disease and all-cause mortality, and between the intake of green-yellow vegetables and cruciferous vegetables and total cancer risk. An estimated 5.6 and 7.8 million premature deaths worldwide in 2013 may be attributable to a fruit and vegetable intake below 500 and 800 g/day, respectively, if the observed associations are causal. Conclusions Fruit and vegetable intakes were associated with reduced risk of cardiovascular disease, cancer and all-cause mortality. These results support public health recommendations to increase fruit and vegetable intake for the prevention of cardiovascular disease, cancer, and premature mortality.

Abstract
Objective: There's a shortage of evidence on the oral health of quilombolas. This study aims to describe oral health self-perception, as well as to verify its associated factors in quilombola communities in the state of Rio Grande do Sul. Methods: The data for this cross-sectional health survey were collected by application of a questionnaire. Since this study was part of a survey on nutritional security, the probabilistic cluster sample was estimated for the outcome of nutritional insecurity, comprising 583 individuals across quilombola communities in Rio Grande do Sul. The association between the outcome of negative oral health self-perception and sociodemographic, general health, and oral health variables was measured by prevalence ratios obtained through Poisson regressions with robust variance and 95% confidence intervals. Results: Negative self-rated oral health was reported by 313 (53.1%) of the individuals. Satisfaction with chewing ability and satisfaction with oral appearance were associated with a higher prevalence of negative perception of oral health, while there was no association between the outcome and number of teeth. Use of alcohol had a borderline association with the outcome. Conclusion: Satisfaction with appearance and chewing ability are factors associated with oral-health self-perception of the quilombolas in Rio Grande do Sul.

Gender differences in the roles for social support in ensuring adequate fruit and vegetable consumption among older adult Canadians. Appetite 2015; 92:102-9. [PMID: 25981151 DOI: 10.1016/j.appet.2015.05.011] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2014] [Revised: 04/17/2015] [Accepted: 05/11/2015] [Indexed: 12/19/2022]
Abstract
BACKGROUND Adequate fruit and vegetable consumption has been linked to reductions in all-cause mortality, stroke, and cancer. Unfortunately, less than half of Canadians aged 65+ meet the standard international guideline for adequate consumption (≥5 servings per day). Among older adults, social isolation and low social support are barriers to proper nutrition, but the effects of specific types of social support on adequate fruit and vegetable consumption are unknown. OBJECTIVE This study sought to test hypotheses regarding direct and indirect pathways through which tangible and emotional/informational social support may facilitate adequate fruit and vegetable consumption among older adults. METHODS Analyzing 2008-2009 Canadian Community Health Survey - Healthy Aging component data (n = 14,221), logistic regression models were developed to examine associations between tangible and emotional/informational social support, eating behaviors (eating alone and preparing one's own meals), and meeting the recommended guideline of consuming ≥5 servings of fruit and vegetables per day. RESULTS In pooled models, emotional/informational support was positively associated with adequate fruit and vegetable consumption (OR = 1.16; 95% CI = 1.07, 1.27). Among men, neither social support form was directly or indirectly associated with adequate consumption; among women, adequate consumption was negatively associated with tangible support but positively associated with higher emotional/informational support. Both of these associations were mediated by not usually cooking one's own meals. CONCLUSIONS Programs and policies that seek to foster social support for older adults as a means of ensuring proper nutrition should consider the nuanced mechanisms through which different social support forms may operate for men and women.

Abstract
Longevity is a very complex phenomenon, because many environmental, behavioral, socio-demographic and dietary factors influence the physiological pathways of aging and life-expectancy. Nutrition has been recognized to have an important impact on overall mortality and morbidity; and its role in extending life expectancy has been the object of extensive scientific research. This paper reviews the pathophysiological mechanisms that potentially link aging with diet and the scientific evidence supporting the anti-aging effect of the traditional Mediterranean diet, as well as of some specific foods. The diet and several of its components have additionally been shown to have beneficial effects on the co-morbidities typical of elderly populations. Furthermore, the epigenetic effects of diet on the aging process - through calorie restriction and the consumption of foods like red wine, orange juice, probiotics and prebiotics - have attracted scientific interest. Some, such as dark chocolate, red wine, nuts, beans, avocados are being promoted as anti-aging foods, due to their anti-oxidative and anti-inflammatory properties. Finally, an important moderator in the relationship between diet, longevity and human health remains the socio-economic status of individual, as a healthy diet, due to its higher cost, is closely related to higher financial and educational status.

Abstract
IMPORTANCE Some evidence suggests vegetarian dietary patterns may be associated with reduced mortality, but the relationship is not well established. OBJECTIVE To evaluate the association between vegetarian dietary patterns and mortality. DESIGN Prospective cohort study; mortality analysis by Cox proportional hazards regression, controlling for important demographic and lifestyle confounders. SETTING Adventist Health Study 2 (AHS-2), a large North American cohort. PARTICIPANTS A total of 96,469 Seventh-day Adventist men and women recruited between 2002 and 2007, from which an analytic sample of 73,308 participants remained after exclusions. EXPOSURES Diet was assessed at baseline by a quantitative food frequency questionnaire and categorized into 5 dietary patterns: nonvegetarian, semi-vegetarian, pesco-vegetarian, lacto-ovo-vegetarian, and vegan. MAIN OUTCOME AND MEASURE The relationship between vegetarian dietary patterns and all-cause and cause-specific mortality; deaths through 2009 were identified from the National Death Index. RESULTS There were 2570 deaths among 73,308 participants during a mean follow-up time of 5.79 years. The mortality rate was 6.05 (95% CI, 5.82-6.29) deaths per 1000 person-years. The adjusted hazard ratio (HR) for all-cause mortality in all vegetarians combined vs nonvegetarians was 0.88 (95% CI, 0.80-0.97). The adjusted HR for all-cause mortality in vegans was 0.85 (95% CI, 0.73-1.01); in lacto-ovo-vegetarians, 0.91 (95% CI, 0.82-1.00); in pesco-vegetarians, 0.81 (95% CI, 0.69-0.94); and in semi-vegetarians, 0.92 (95% CI, 0.75-1.13) compared with nonvegetarians. Significant associations with vegetarian diets were detected for cardiovascular mortality, noncardiovascular noncancer mortality, renal mortality, and endocrine mortality. Associations in men were larger and more often significant than were those in women. CONCLUSIONS AND RELEVANCE Vegetarian diets are associated with lower all-cause mortality and with some reductions in cause-specific mortality. Results appeared to be more robust in males. These favorable associations should be considered carefully by those offering dietary guidance.

Abstract
OBJECTIVE To explore older independently-living Australians' perceptions and practices about what constitutes a healthy diet for older people. DESIGN Qualitative methodology, focus groups. SETTING Independently-living retirees in Northern NSW, Australia. PARTICIPANTS A total of 29 participants in five focus groups, ranging in age from 60-93 years, with a mean age of 73.3 ± 8.8years; the majority (79%) were women. RESULTS Thematic analysis of the focus group interviews revealed four themes that best represent older people's perceptions and practices in relation to healthy eating for old age. These included: 1) healthy foods - participants believed in a hierarchy of perceived healthfulness or importance of foods; 2) quantity - participants believed that ageing was associated with a reduced dietary intake and less need for meat; 3) personal circumstances - participants acknowledged that food costs, social situations and health conditions influenced their food choices; and 4) good intention - participants acknowledged that the desire to regain or maintain wellbeing and to preserve health positively influenced their food choices. Participants were unaware of the national nutrient targets for older Australians. CONCLUSION The trend towards reduced dietary intake of meat and the indifference to dairy products expressed by many participants in this study suggests that they are at risk of not achieving the requirements for protein and calcium in particular. Failure to meet these age-adjusted nutrient targets has important implications for the health and functional capacity of older people.

Abstract
BACKGROUND Few studies have evaluated the linkage between food cost and mortality among older adults. This study considers the hypothesis that greater food expenditure in general, and particularly on more nutritious plant and animal-derived foods, decreases mortality in older adults. METHODS This study uses the 1999-2000 Elderly Nutrition and Health Survey in Taiwan and follows the cohort until 2008, collecting 24-hr dietary recall data for 1781 participants (874 men and 907 women) aged 65 y or older. Using monthly mean national food prices and 24-hr recall, this study presents an estimate of daily expenditures for vegetable, fruit, animal-derived, and grain food categories. Participants were linked to the national death registry. RESULTS Of the 1781 original participants, 625 died during the 10-y follow-up period. Among the 4 food categories, the fourth and fifth expenditure quintiles for vegetables and for fruits had the highest survival rates. After adjusting for co-variates, higher (Q4) vegetable and higher fruit (Q4) food expenditures referent to Q1 were significantly predictive of reduced mortality (HR = 0.55, 95% CI: 0.39-0.78 and HR = 0.64, 95% CI: 0.42-0.99, respectively) and the risk decreased by 12% and 10% for every NT$15 (US$0.50) increase in their daily expenditures. Animal-derived and grain food spending was not predictive of mortality. CONCLUSION Greater and more achievable vegetable and fruit affordability may improve food security and longevity for older adults.

Abstract
Chronic kidney disease is considered an inflammatory state and a high fiber intake is associated with decreased inflammation in the general population. Here, we determined whether fiber intake is associated with decreased inflammation and mortality in chronic kidney disease, and whether kidney disease modifies the associations of fiber intake with inflammation and mortality. To do this, we analyzed data from 14,543 participants in the National Health and Nutrition Examination Survey III. The prevalence of chronic kidney disease (estimated glomerular filtration rate less than 60 ml/min per 1.73 m(2)) was 5.8%. For each 10-g/day increase in total fiber intake, the odds of elevated serum C-reactive protein levels were decreased by 11% and 38% in those without and with kidney disease, respectively. Dietary total fiber intake was not significantly associated with mortality in those without but was inversely related to mortality in those with kidney disease. The relationship of total fiber with inflammation and mortality differed significantly in those with and without kidney disease. Thus, high dietary total fiber intake is associated with lower risk of inflammation and mortality in kidney disease and these associations are stronger in magnitude in those with kidney disease. Interventional trials are needed to establish the effects of fiber intake on inflammation and mortality in kidney disease.

Abstract
BACKGROUND An increasing number of people over 60 years of age living world-wide undertake appropriate actions in order to identify factors to optimize their health. OBJECTIVE The study was aimed at evaluating nutritional patterns, biochemical parameters (TC, HDL, LDL, TG, glucose) and anthropometric parameters (BMI, waist circumference, arm circumference, triceps skinfold thickness) of 220 subjects over 60 years of age originating from an urban environment. METHODS Nutritional patterns were evaluated by means of a 24-h dietary recall, whereas nutritional status of the subjects was assessed based on anthropometric parameters and selected biochemical assays linked with lipid and carbohydrate metabolism. RESULTS The study demonstrated a low energy value of food rations of the analyzed seniors from Wrocław, an improper proportion of energy supply from particular nutrients: SFA (saturated fatty acid) - 14% and carbohydrates - 52%, as well as low intake of fruits and vegetables, cereal products and dietary fibre, vitamins and minerals. 70% of the women and in 50% of the men were characterized by a high concentration of total cholesterol in blood serum. In turn, ca. 15% of the subjects were shown to have an elevated concentration of glucose. A statistically significant difference was demonstrated between waist circumference of the women and men examined (91.0 +/- 11.8 vs. 100.4 +/- 10.5; p < 0.05) as well as between their glucose concentration in blood (respectively: 88.0 +/- 28.4 vs. 103.5 +/- 24.3; p < 0.05). In 25 women, skinfold thickness was over 25 mm and mean BMI reached 30. In 40 seniors, skinfold thickness exceeded 11 mm, whereas BMI was lower and reached 25. CONCLUSION In most of the examined seniors analyses demonstrated deficient nutritional patterns and disturbed processes of lipid metabolism. The study indicates the need for further extensive investigations of factors that determine the health status of the seniors.
