ABSTRACTThe sources or types of protein in the diet have long been overlooked regarding their link to cardiometabolic health. The picture is complicated by the fact that animal and plant proteins are consumed along with other nutrients and substances which make up the “protein package” so plant and animal protein come with clear nutrient clusters. This review aimed at deciphering the relation between plant and animal protein and cardiometabolic health by examining different nutritional levels (such as amino acids, protein type, protein foods, protein patterns, and associated overall dietary and nutrient patterns) and varying levels of scientific evidence [basic science, randomized controlled trials (RCTs), observational data]. Plant protein in Western countries is a robust marker of nutrient adequacy of the diet, whereas the contribution of animal protein is highly heterogeneous. Yet recent data from large cohorts have confirmed that total and animal proteins are associated with the risk of cardiovascular disease and diabetes, even when fully adjusting for lifestyle and dietary or nutritional factors. Here again, there is marked variability depending on the type of animal protein. Protein from processed red meat and total red meat on the one hand, and from legumes, nuts, and seeds on the other, are often reported at the extremes of the risk range. RCTs using purified proteins have contributed little to the topic to date, inasmuch as the findings cannot readily be extrapolated to current or near-future diets, but RCTs studying whole protein foods have shown a beneficial effect of pulses. Despite the fact that many of the benefits of plant protein reported in observational or interventional studies may stem from the protein package that they convey and the nutrients that they displace, there are also important indications that protein per se may affect cardiometabolic health via the many amino acids that are present in typically contrasting levels in plant compared with animal proteins.

  Background: Using of herbs and spices greatly affect the taste of foods, although the ingredients used are the same, different formulations of herbs will produce different flavors. Standardized seasonings are needed to produce a relatively similar food taste. Objective: The research aims to determine the use of herbs in animal and plant proteins. Method: This research was an observational research with cross sectional approach at PanembahanSenopati Hospital Bantul. The objects of this research were standardized seasonings inanimal and plant proteinsin the menu cycle of 10 days in Juny 2015. The data were analyzed descriptively and presented in tabular form and textural. Result: Standardized Seasonings in animal protein were B for satay and C for semur. Standardized seasonings in plant protein were B for bali, terik, rujak and D for bacem. The percentage of the use of seasoning than standardized seasoning for satay (148,7%), bali (130,3%), rujak(372%),for semur, terik and bacem the conformity are not not known because the standardized seasonings unwritten. The conformity of ingredient herbskind for satay (66,7%), semur (100%), bali (54,5%), rujak (50%), bacem (100%) and terik (100%).

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 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.

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 A dietary shift in favor of plant protein (PP) sources over animal protein (AP) sources has been advocated for both sustainability and health reasons, this dietary transition being noticeably associated to decreased cardiovascular and diabetes risks. The differences in amino acid composition between PP and AP may have several effects on the metabolic pathways, and in turn health impacts, which are still poorly characterized. This project aims at characterizing, with a combination of “omics” approaches, the metabolic reorientations induced by a dietary shift from AP to PP sources and understanding their health effects in a population at cardiometabolic risk. Methods We will conduct a cross-over randomized feeding trial (NCT04236518) in 20 healthy overweight males (BMI 25–35), aged 25–55, with an enlarged waist circumference (&gt; 94cm) and high plasma triglycerides (&gt;1.5g/L). Participants will be assigned for 1 month each to 2 diets containing predominantly either AP (65% AP:35% PP) or PP (35% AP:65% PP) in a randomized order, separated by a 2-week wash-out period. Lunch and diner will be directly provided while dietary guidelines will be given for breakfast and snacks. Blood, urine and stool samples will be collected at the fasted state every 2 weeks. At the end of each dietary intervention, blood and urine will be collected following a high fat meal, which challenges metabolism and vascular homeostasis. Plasma and urine non-targeted metabolomics analyses (LC-MS) will be combined with Peripheral Blood Mononuclear Cell (PBMC) transcriptomics and fluxomics analyses (D2O tracer) to get a comprehensive overview of the metabolic phenotype associated with AP or PP intake. Flow-Mediated Dilatation (FMD) and Flow Laser Doppler (FLD) will be used to measure respectively macrovascular endothelial function and microvascular skin blood flow at the fasted state and after the high-fat meal. We will also measure anthropometric parameters and analyze biochemistry and inflammatory markers. Results Not applicable (protocols abstract). Conclusions We expect the multi-omics fingerprinting to reveal subtle metabolic differences associated to AP or PP intake, with a positive effect of PP intake. Improved inflammatory status and endothelial function are also expected to be associated to PP intake. Funding Sources INRAE and Roquette Frères.

The experiment was done in the experimental station ÚKZÚZ Havlíčkův Brod. There were four experimental groups (N1, N2, N3, N4) of laying hens and weekly laying intensity was observed. Hybrid ISA BROWN was used in the experiment, 405 hens in each group. The laying intensity was observed from the start of laying for 44 weeks. During laying four different diets were fed to laying hens (N1 – control group with fish meal, N2 – control group containing only of plant protein sources, N3 – experimental group with higher content of rapeseed, N4 – experimental group containing treated rapeseed). Yang model was used for the evaluation of laying curves and we found following parameters of the curves:Yang model N1: y = 97.28 * e – 0.004 * t / [1 + e – 2.054 (t – 2.549)] R2 = 0.97Yang model N2: y = 98.29 * e – 0.006 * t / [1 + e – 2.071 (t – 2.668)] R2 = 0.96Yang model N3: y = 98.49 * e – 0.005 * t / [1 + e – 1.856 (t – 2.568)] R2 = 0.97Yang model N4: y = 98.55 * e – 0.005 * t / [1 + e – 2.251 (t – 2.615)]. R2 = 0.97The results document that experimental treatments had small effect on the parameters of laying curves. It means that rapeseed had only small effect on the laying intensity and also the elimination of animal protein from the diet for laying hens had not effect on laying intensity. On the base of our results we estimated the standard equation for evaluation of laying curve:Yang model: y = 98.15 * e – 0.005 * t / [1 + e – 2.058 (t – 2.601)]. R2 = 0.99This equation can be used as standard for evaluation of laying intensity after experimental treatments or for evaluation of laying intensity of different hybrids.

Abstract The objective of the study was to investigate the effect of different protein sources and nutrient specification levels on the gut microbiome composition of nursery pigs. A total of 120 crossbred gilts (Large White ′ Landrace ′ Duroc, initial BW 6.74 ± 0.06 kg, 18 days of age) were allotted to 1 of 6 treatments: animal protein source with nursery diet specifications (AN); animal protein source with grower diet specifications (AG); plant protein source with nursery specifications (PN); plant protein source with grower diet specifications (PG); plant protein source, nursery diet specifications, and an enzyme + essential oil cocktail (PN+EOE), and plant protein source, grower diet specifications, and an enzyme + essential oil cocktail (PG+EOE). There were 4 pigs per replicate and 5 replications per treatment, in a randomized block design. On d 43, 1 pig per replicate was sacrificed, and cecum and colon digesta samples were collected for gut microbiome analysis and profiled though MiSeq 16S rRNA sequencing. Data were analyzed using univariate and multivariate methods within R. No differences in alpha or beta diversity were detected based on protein source, nursery diet specification, or inclusion of EOE; however, a number of discriminating taxa were present between pigs fed treatments with different protein sources. For instance, abundance of Parabacteroides was increased in colonic PG samples (P = 0.01) compared with AG, and abundance of Lachnospiraceae was increased in all samples of AG compared with PG (P = 0.009). Eubacterium (P = 0.044) and Turicibacter (P = 0.031) were both more abundant in colonic AN samples when compared with PN samples. In conclusion, the gut microbial communities, at large, in the cecum or colon, were not significantly modified by the presence of different protein sources in nursery diets.
