Abstract Objectives To study the relationship between maternal dietary protein patterns in pregnancy and the risk of infant eczema. Methods A total of 714 mother-child pairs from a birth cohort in Guangzhou, China were studied. Maternal dietary intake was collected by a face-to-face food frequency questionnaire(FFQ) at 20–28 weeks' gestation, and protein intake of each food group was calculated for subsequent K-means cluster analysis to determine dietary protein patterns. Telephone interviews were used to collect parent-reported infant eczema data at age 6 months. The association between maternal dietary protein patterns and infant eczema was tested by using logistic regression models, after adjustment for potential confounders. Results Cumulative incidence of eczema by 6 months of age was 51.26%. Four dietary protein patterns were identified according to the dietary protein sources, including poultry pattern (characterized by a relatively higher protein intake from poultry), plant pattern (characterized by a relatively higher protein intake from grain, soybean, vegetables, nuts and seeds), dairy and egg pattern (characterized by a relatively higher protein intake from dairy, eggs, and fruits), and red meat and seafood pattern (characterized by a relatively higher protein intake from red meat, fish and seafood). Compared to the poultry dietary pattern, plant pattern and dairy and egg pattern were associated with a reduced risk of developing infant eczema: the adjusted odds ratios (95% confidence interval) were 0.572(0.330–0.992) and 0.288(0.279–0.854) respectively. No such association was observed in red meat and seafood pattern. Conclusions The maternal plant and dairy and egg dietary protein patterns in pregnancy may be preventive against infant eczema.

Background: Previous studies have suggested that maternal dietary protein was associated with allergic diseases in offspring, but few studies have evaluated the influence of dietary protein patterns. This study aimed to explore the prospective association between maternal dietary protein patterns during pregnancy and the risk of infant eczema.Methods: A total of 713 mother-child pairs from a prospective cohort in Guangzhou, China were recruited. Maternal dietary protein was estimated using a validated face-to-face food frequency questionnaire at 20–28 weeks' gestation from 2017 to 2018. Dietary protein patterns were calculated based on the sources of protein. The data of infant eczema was assessed at 6 months of age using the symptom questionnaire of eczema. Logistic regression was carried out to examine the associations between maternal dietary protein patterns and infant eczema.Results: The cumulative incidence of infant eczema at 6 months of age was 51.19%. Mothers of infants with eczema consumed more protein from poultry source during pregnancy than mothers of infants without eczema, while no statistical differences were observed in maternal intakes of protein from cereals and tubers, vegetables, fruits, red meat, fish and seafood, eggs, dairy, soybean, and nuts and seeds. Four dietary protein patterns were identified and termed poultry, plant, dairy and eggs, and red meat and fish. The cumulative incidence of eczema was 61.2, 45.8, 48.0, 51.4% for these four patterns, respectively. Compared to the poultry dietary pattern, the plant pattern and the dairy and eggs pattern were associated with a reduced risk of infant eczema, and the adjusted odds ratios (95% confidence interval) were 0.572 (0.330–0.992), 0.478 (0.274–0.837), respectively. No such association was observed for the red meat and fish dietary protein pattern.Conclusion: This is the first study that focused on the association between maternal dietary protein during pregnancy from a whole-diet perspective and infant eczema. Compared with the poultry dietary protein pattern, the maternal plant pattern and the dairy and eggs pattern during pregnancy were associated with a reduced risk of infant eczema.

Protein intake, food sources and distribution are important in preventing age-related loss of muscle mass and strength. The prevalence and determinants of low protein intake, food sources and mealtime distribution were examined in 214 Māori and 360 non-Māori of advanced age using two 24 h multiple pass recalls. The contribution of food groups to protein intake was assessed. Low protein intake was defined as ≤0.75 g/kg for women and ≤0.86 g/kg for men. A logistic regression model was built to explore predictors of low protein intake. A third of both women (30.9%) and men (33.3%) had a low protein intake. The main food group sources were beef/veal, fish/seafood, milk, bread though they differed by gender and ethnicity. For women and men respectively protein intake (g/meal) was lowest at breakfast (10.1 and 13.0), followed by lunch (14.5 and 17.8) and dinner (23.3 and 34.2). Being a woman (p = 0.003) and having depressive symptoms (p = 0.029) were associated with consuming less protein. In adjusted models the odds of adequate protein intake were higher in participants with their own teeth or partial dentures (p = 0.036). Findings highlight the prevalence of low protein intake, uneven mealtime protein distribution and importance of dentition for adequate protein intake among adults in advanced age.

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.

Abstract Objectives Plant-based foods (PBFs) are in cutting edge of nutrition due to well-established physical and environmental health benefits. The knowledge of amino acid (AA) composition of PBFs is crucial to evaluate the protein intake. This work aims to assess how PBFs can contribute to the protein intake, according to the Mediterranean diet's reference portions. Methods Protein quality was determined in 58 PBFs belonging to cereals and tubers, vegetables, fruits, legumes, animal protein substitutes and algae available in Portuguese markets. The AA score and specific intake estimated in agreement with WHO, National recommendation and Portuguese food consumption patterns, after UPLC/PDA analysis. Results The highest protein content found in algae, with 35.1 ± 1.2 g/100g DW, and animal protein substitutes with 26.1 ± 0.8 g/100g. Regarding the essential AA scores, by food group, histidine, threonine and aromatic amino acids (AAA) present scores above 1 (1 to 3.5) and lysine, valine and isoleucine current results below 1 for all food groups, despite that lysine in legumes have a 0.9 score. Only legumes for leucine, and cereals and meat substitutes for sulfur AA have scores greater than 1. They are considering the maximum recommended portions, for Portuguese consumption, each of the food groups supplies between 400% of AAA and 100% of lysine regarding essential AA. According to data of consumption on specific plant food groups, an average of 80% of the recommended intake is represented by AAA, and the Portuguese population consumes 15% lysine. The primary sources, of essential AA that contribute to the Portuguese intake, are cereals and tubers with 67.9% of AAA in men and 56.3% in women and 10% of lysine in men and 8.3% in women. The groups of vegetables, legumes and fruits contribute less than 10% of all essential AA. Conclusions Complementarity and diversity of PBFs can reduce some essential AA to achieve the established protein recommendations. A combination of different food groups, such as cereals and legumes, should be taken into account. Increasing seaweed consumption, legumes, and vegetables should be encouraged to the general population.

During pregnancy, the accumulation of long-chain polyunsaturated fatty acids (LCPUFA) in fetal tissues places a substantial demand upon maternal lipid metabolism. As lipid metabolism is intimately linked to aspects of protein metabolism, a reduced protein intake in pregnancy may impair activities of enzymes and transport proteins responsible for supplying LCPUFA to the fetus, thereby compromising fetal development. We have investigated the effect of reduced protein intake on LCPUFA status in the non-pregnant rat and in the pregnant rat, and in fetus at day 20 of gestation. Female rats (n5 per group) were either mated and fed the control diet (180 g protein/kg) or low-protein diet (90 g protein/kg, LPD) diet throughout pregnancy, or fed the control diet or LPD for 20 d (non-pregnant animals). The fatty acid compositions of maternal liver and plasma, and fetal liver and brain were determined by GC. Feeding the LPD did not lead to any gross changes either in adult or fetal growth, or in total lipid concentrations in adult rat liver. However, the LPD was associated specifically with lower liver (42·6 %) and plasma (19·4 %) phosphatidylcholine (PC), and plasma triacylglycerol (28·6 %) docosahexaenoic acid (DHA) concentrations in pregnant rats and reduced fetal brain PC- (26·1 %) and phosphatidylethanolamine- (25·6 %) DHA concentrations. Together, these results show that variations in maternal dietary protein consumption alter DHA status in pregnancy and modify DHA accumulation into the fetal brain. The present results suggest that lower maternal protein intakes reduce delivery of DHA from the mother to the fetus, which may impair development and function of the fetal brain.

Diet in the first years of life is an important factor in growth and development. Dietary protein is a critical macronutrient that provides both essential and nonessential amino acids required for sustaining all body functions and procedures, providing the structural basis to maintain life and healthy development and growth in children. In this study, our aim was to describe the total protein intake, type and food sources of protein, the adequacy to the Population Reference Intake (PRI) for protein by the European Food Safety Authority (EFSA), and the Recommended Dietary Allowance (RDA) by the Institute of Medicine (IoM). Furthermore, we analyzed whether the consumption of dairy products (including regular milk, dairy products, or adapted milk formulas) is associated with nutrient adequacy and the contribution of protein to diet and whole dietary profile in the two cohorts of the EsNuPI (in English, Nutritional Study in the Spanish Pediatric Population) study; one cohort was representative of the Spanish population from one to < 10 years old (n = 707) (Spanish reference cohort, SRS) who reported consuming all kinds of milk and one was a cohort of the same age who reported consuming adapted milk over the last year (including follow-on formula, growing up milk, toddler’s milk, and enriched and fortified milks) (n = 741) (adapted milk consumers cohort, AMS). The children of both cohorts had a high contribution from protein to total energy intake (16.79% SRS and 15.63% AMS) and a high total protein intake (60.89 g/day SRS and 53.43 g/day AMS). We observed that protein intake in Spanish children aged one to < 10 years old was above the European and international recommendations, as well as the recommended percentages for energy intakes. The main protein sources were milk and dairy products (28% SRS and 29% AMS) and meat and meat products (27% SRS and 26% AMS), followed by cereals (16% SRS and 15% AMS), fish and shellfish (8% in both cohorts), eggs (5% SRS and 6% AMS), and legumes (4% in both cohorts). In our study population, protein intake was mainly from an animal origin (meat and meat products, milk and dairy products, fish and shellfish, and eggs) rather than from a plant origin (cereals and legumes). Future studies should investigate the long-term effect of dietary protein in early childhood on growth and body composition, and whether high protein intake affects health later in life.
