Low variability of plant protein intake in the CKiD cohort does not demonstrate changes in estimated GFR nor electrolyte balance

Abstract Background In general, plant protein intake was inversely associated with mortality in studies in middle-aged adults. Our aim was to evaluate the long-term associations of animal and plant protein intake with mortality in older adults. Methods A prospective cohort study including 1,139 community-dwelling older adults (mean age 75 years, 56% women) living in Tuscany, Italy, followed for 20 years (InCHIANTI study) was analyzed. Dietary intake by food frequency questionnaires and clinical information were assessed five times during the follow-up. Protein intakes were expressed as percentages of total energy. Time-dependent Cox regression models adjusted for confounders were used to assess the association between plant and animal protein intake, and mortality. Results During the 20-years of follow up (mean: 12y), 811 deaths occurred (292 of cardiovascular- and 151 of cancer-related causes). Animal protein intake was inversely associated with all-cause (HR per 1% of total energy from protein increase, 95%CI: 0.96, 0.93-0.99) and cardiovascular mortality (HR per 1% of total energy from protein increase, 95%CI: 0.93, 0.87-0.98). Plant protein intake showed no association with any of the mortality outcomes, but an interaction with baseline hypertension was found for all-cause and cardiovascular mortality (p<0.05). Conclusions Animal protein was inversely associated with all-cause and cardiovascular mortality in older adults. Further studies are needed to provide recommendations on dietary protein intake for older adults.

Abstract Objective: The aim of the present study was to investigate the differences between the consumption of plant-based v. animal-based protein-rich diets on successful ageing, as well as to identify the optimal combination of dietary protein intake for facilitating successful ageing in people aged >50 years. Design: A combined analysis was conducted in older adults of the ATTICA and MEDIS population-based cross-sectional studies. Anthropometrical, clinical and sociodemographic characteristics, lifestyle parameters, dietary habits and level of protein intake were derived through standard procedures. Successful ageing was evaluated using the validated Successful Aging Index (SAI) composed of ten health-related social, lifestyle and clinical characteristics. Setting: Athens area and twenty Greek islands. Participants: A total of 3349 Greek women and men over 50 years old. Results: Participants with high consumption of plant proteins were more likely to be male, physically active, with higher daily energy intake, higher adherence to the Mediterranean diet and higher level of SAI (P < 0·001). Participants with ‘Low animal & High plant’ and ‘High animal & High plant’ protein consumption had a 6 and 7 % higher SAI score, respectively, compared with the other participants (P < 0·001). In contrast, ‘Low animal & Low plant’ and ‘High animal & Low plant’ protein intake was negatively associated with SAI as compared to the combination of all other consumption categories (P < 0·02). Conclusions: The consumption of a plant-based protein-rich diet seems to be a beneficial nutritional choice that should be promoted and encouraged to older people since it may benefit both individual’s health and prolong successful ageing.

Abstract Objectives Metabolic syndrome is a precursor to many leading causes of death in the United States including cardiovascular disease, stroke, and diabetes. Diet plays a major role in preventing or exacerbating the development of metabolic syndrome. Increasing plant protein intake may help to reduce risk of developing metabolic syndrome. The purpose of this study was to examine the possible relationship between metabolic syndrome progression and % of protein from plant sources in the diet. Methods The ARIC dataset was used to compare changes in the number of metabolic syndrome criteria (0-5) over a 9-year period to average % of protein from plant sources for 10,038 Americans age 45–64. Quartiles of plant protein intake were controlled for important covariates in linear regression. Results As hypothesized, quartiles with higher percentages of protein intake from plant sources showed a decrease in metabolic syndrome score [B (change in metabolic syndrome score over 9 years per plant protein quartile) = -0.039; 95% confidence interval (CI): -0.063, -0.016] over 9 years of follow up. Waist circumference was the most significantly associated metabolic syndrome factor (B = -0.053; 95% CI -0.030, -0.011). A decrease in BMI was similarly correlated with higher intakes of plant proteins (B = -0.077; 95% CI -0.214, -0.0112). Conclusions These results suggest that a higher intake of plant proteins could be protective against increased BMI, waist circumference, and worsening metabolic syndrome and therefore may reduce risk of cardiovascular disease, diabetes, and stroke.

ABSTRACT Background There is a current trend in Western countries toward increasing the intake of plant protein. A higher plant-protein intake has been associated with nutritional and health benefits, but these may depend on the pattern of plant-protein sources. Objective We hypothesized that the diversity of plant foods could be important to nutrient adequacy when increasing plant-protein intake in the diet. Methods Using data on 1341 adults (aged 18–64 y) from a representative French national dietary survey conducted in 2014–2015 (the third Individual and National Study on Food Consumption Survey—INCA3), we studied the links between plant-protein intake, dietary diversity (using various dimensions), and nutrient adequacy [assessed using the PANDiet (Probability of Adequate Nutrient Intake) scoring system, comprising adequacy (AS) and moderation (MS) subscores]. We simulated substituting plant-protein foods for animal-protein foods using different models of plant-protein diversity. Results We found that overall diet quality was weakly associated with total and protein diversity and more strongly with plant-protein diversity. Plant-protein intake was inversely associated with animal-protein intake, and positively with the PANDiet and MS, but not with the AS. Plant-protein intake displayed little diversity, mostly taking the form of grains (61% of plant-protein intake), and this diversity was even less marked under a higher plant-protein intake. Finally, modeled substitutions showed that reducing animal-protein intake increased the MS (by 32%) in a similar manner whichever plant protein was used for substitution, whereas it decreased the AS (by 20%) unless using a highly diversified plant-protein mix. These simulated improvements in overall adequacy included marked decreases in adequacy regarding certain nutrients that are typically of animal origin. Conclusions We conclude that in French adults the current pattern of plant-protein intake is hindering the nutritional benefits of a transition toward more plant protein, indicating that the consumption of plant-protein-based foods other than refined grains should be encouraged.

Anthropometric Indices

Background: Adolescent girls in Afghanistan have high levels of food insecurity, yet little is known about their dietary intakes. Therefore, we aimed to study the association between dietary protein intake and anthropometric indices among adolescent girls in Kabul, Afghanistan. Methods: We conducted a cross-sectional study of 380 adolescent girls at 16 government schools from eight randomly sampled zones in Kabul. In July 2019, we assessed dietary intake, body mass index (BMI), physical activity and socio-demographic variables. Binary logistic regression models were used to estimate the associations between different protein sources (plant protein, animal protein and total protein) and stunting, wasting, overweight and obesity. Results: Participant mean age was 14.8±2 years and mean BMI was 19.8±3.6kg/m2. The mean intakes of carbohydrates from plant proteins, animal proteins and total proteins were approximately 59.4±19.6gr/day, 22.3±7.3gr/day and 81.8±27.1gr/day, respectively. Students with more highly educated fathers consumed more plant proteins (P<0.05). Participants had overall high dietary plant protein intake (mean 34.8±22.0g/day), with 66% from grains, cereals and flour. We did not find an association between dietary protein intake and stunting (OR=0.92; CI: 0.55-1.54), wasting (OR= 0.98; CI: 0.55-1.78), overweight (OR=1.18; CI: 0.62-2.25) or obesity (OR=0.84; CI: 0.19-3.58). Conclusion: While prior research suggests that dietary protein intake is associated with improved nutritional and anthropometric indices, dietary protein intake in this study was not associated with stunting, wasting, overweight and obesity. Further investigation is needed on this topic.

Abstract Objectives The objective was to examine the prospective association of major dietary protein sources with all-cause and cause-specific mortality in U.S. women. Methods We included 127,495 postmenopausal women aged 50 to 79 years old at study entry who were enrolled between 1993 and 1998 in the Women's Health Initiative from September 1993, and followed through February 2017. Prospective cohort study. We used multivariable Cox proportional hazards models to estimate adjusted HRs of all cause, cardiovascular, cancer and dementia mortality in relation to major protein sources. Results During 2,302,230 person-years of follow-up, 35,043 deaths occurred. Total protein or animal protein intake was not significantly associated with all-cause or cause-specific mortality. Plant protein intake was inversely associated with all-cause, CVD and dementia mortality, with multivariable-adjusted HRs (95% CIs), comparing the higher with the lowest quintile, as 0.91 (0.86, 0.95), 0.87 (0.79, 0.95), and 0.81 (0.70, 0.94), respectively. Substituting 5% energy from animal protein with plant protein was associated with a 13% lower risk of all-cause mortality. For major protein sources, consumption of unprocessed red meat, processed red meat, and eggs, was associated with higher risk of all-cause mortality, with multivariable-adjusted HRs (95% CIs), comparing the higher with the lowest quintile, as 1.07 (1.03, 1.11), 1.07 (1.03, 1.11), and 1.14 (1.10, 1.18), respectively, while nut consumption was associated with a slightly lower risk of all-cause mortality, with multivariable-adjusted HRs (95% CIs), comparing the higher with the lowest quintile, as 0.97 (0.93, 0.99). Substituting 4 ounce equivalent/day of total red meat with poultry, fish/shellfish, or nuts, was associated with a 8%, a 12%, and a 12% lower risk of all-cause mortality, respectively. Conclusions Different dietary protein sources have varying associations with lower all-cause, CVD and dementia mortality. Substituting total red meat with poultry, fish/shellfish, or nuts was associated with lower risk of all-cause mortality. Funding Sources NIH.

Socioeconomic status affects food choices. This study examined the relationships between socioeconomic status (SES) and animal and plant protein intake in the Korean elderly population whose protein intake is insufficient. We used cross-sectional data from 3512 Koreans aged 60 years or older, who had participated in the Nutrition Survey of the 2013–14 Korea National Health and Nutrition Examination Survey (KNHANES). One day 24-h recall data was used to estimate the daily total, animal, and plant protein intake. Household income and educational attainment were assessed by trained interviewers. After making adjustment, household income was positively associated with animal protein intake with a statistical significance in females (p = 0.030) and with a marginal significance in males (p = 0.069). However, plant protein intake did not show any significant association. In both sexes, educational attainment was positively associated with animal protein intake (p = 0.007 for males, p = 0.001 for females). Association of educational attainment with plant protein intake was negative in males (p = 0.037) and non-significant in females. (p = 0.945). High SES was associated with higher total protein intake and animal protein intake in the Korean elderly. Health policies and nutrition education are needed to improve protein intake of the vulnerable Korean elderly with low SES.
