Plant-based and animal-based protein intake have differential effects on various aging-related health outcomes, but less is known about the health effect of isocaloric substitution of plant-based and animal-based protein. This systematic review summarized current evidence of the isocaloric substitutional effect of plant-based and animal-based protein on aging-related health outcomes. PubMed and Embase databases were searched for epidemiologic observational studies published in English up to 15 March 2021. Studies that included adults ≥18 years old; use of a nutritional substitution model to define isocaloric substitution of plant protein and animal protein; health outcomes covering mortality, aging-related diseases or indices; and reported association estimates with corresponding 95% confidence intervals were included. Nine cohort studies and 3 cross-sectional studies were identified, with a total of 1,450,178 subjects included in this review. Consistent and significant inverse association of substituting plant protein for various animal proteins on all-cause mortality was observed among 4 out of 5 studies with relative risks (RRs) from 0.54 to 0.95 and on cardiovascular disease (CVD) mortality among all 4 studies with RRs from 0.58 to 0.91. Among specific animal proteins, the strongest inverse association on all-cause and CVD mortality was identified when substituting plant protein for red and/or processed meat protein, with the effect mainly limited to bread, cereal, and pasta protein when replacing red meat protein. Isocaloric substitution of plant-based protein for animal-based protein might prevent all-cause and CVD-specific mortality. More studies are needed on this topic, particularly for cancer incidence and other specific aging-related diseases.

Background and Aims: This study aimed to examine the associations between the total protein intake as well as types and sources of proteins with the gestational diabetes mellitus (GDM) risk.Method and Results: This was a prospective cohort study of the pregnant women in Malaysia. In this study, the total, animal, and plant protein intakes were assessed using a semi-quantitative food frequency questionnaire. Of the 452 women, 48 (10.62%) were diagnosed with GDM. From pre-pregnancy to second trimester, most of the women had 10–20% of energy intake from protein (88.9–90.3%) and ≥75% of recommended protein intake (74.6–86.5%). The women in the highest tertile (T3) of total animal protein intake [adjusted odds ratio (AOR) = 2.76, 95% CI = 1.27–6.04] and red meat protein (AOR = 2.69, 95% CI = 1.27–5.70), specifically in the second trimester, had significantly higher GDM risk compared with the women in the middle tertile of intake (T2). Interestingly, the women in the T3 of egg protein in the second trimester were significantly at lower GDM risk (AOR = 0.43, 95% CI = 0.18–0.91) compared with those in T2.Conclusion: The highest tertile of animal protein (≥42.15 g/day) intake, particularly red meat protein in the second trimester was positively associated with the GDM risk, whereas the highest tertile of egg protein was inversely associated with the GDM risk. Protein intake before or during early pregnancy was not associated with the GDM risk. These findings underscore the importance of sources and types of protein intake, particularly after the first trimester of pregnancy, in relation to GDM risk.

The overconsumption of meat has been charged with contributing to poor health and environmental degradation. Replacing meat with non-meat protein sources is one strategy advocated to reduce meat intake. This narrative review aims to identify the drivers and inhibitors underlying replacing meat with non-meat protein sources in omnivores and flexitarians in developed countries. A systematic search was conducted in Scopus and Web of Science until April 2021. In total, twenty-three studies were included in this review examining personal, socio-cultural, and external factors. Factors including female gender, information on health and the environment, and lower price may act as drivers to replacing meat with non-meat protein sources. Factors including male gender, meat attachment, food neophobia, and lower situational appropriateness of consuming non-meat protein sources may act as inhibitors. Research is needed to establish the relevance of socioeconomic status, race, ethnicity, religion, health status, food environment, and cooking skills. Future studies should prioritize standardizing the definitions of meat and non-meat protein replacements and examining factors across different consumer segments and types of non-meat protein sources. Thereby, the factors determining the replacement of meat with non-meat protein sources can be better elucidated, thus, facilitating the transition to a healthier and more sustainable diet.

Abstract Objective The study was conducted to determine the prevalence of dysmenorrhea and investigate factors associated with dysmenorrhic pain among university students in Lahore, Pakistan. Design and Setting A cross-sectional study was conducted across various public and private sector universities in Lahore. Methods A self-administered structured questionnaire was used to collect data from 600 randomly selected female university students. Results The prevalence of dysmenorrhea was 91.5%. Age at menarche (odds ratio [OR] = 1.96, 95% confidence interval [CI] = 1.10–3.50) was the only significant factor associated with dysmenorrhea. The mean pain severity score among dysmenorrhic students was 5.62 ± 2.28. Most of the participants (65.8%) were experiencing moderate/severe pain. Univariate analysis showed that irregular cycle (OR [95% CI] = 1.62 [1.13–2.33]), age at menarche of ≤14 years (OR [95% CI] = 1.46 [1.05–2.04]), duration of menses of more than 5 days (OR [95% CI] = 1.42 [1.02–1.99]), stress (OR [95% CI] = 2.16 [1.54–3.03]), moderate meat/protein consumption (OR [95% CI] = 1.55 [1.08–2.21]), and medical specialization (OR [95% CI] = 1.72 [1.17–2.52]) were significantly associated with pain severity among dysmenorrhic female students. Multivariate binary logistic regression analysis revealed that medical specialization (OR [95% CI] = 1.83 [1.22–2.73]), age at menarche (OR [95% CI] = 0.603 [0.42–0.86]), regularity of menses (OR [95% CI] = 1.52 [1.04–2.22]), moderate meat/protein consumption (OR [95% CI] = 1.69 [1.16–2.45]), and stress (OR [95% CI] = 1.87 [1.32–2.66]) were independent predictors of moderate/severe dysmenorrhic pain. Conclusion The study revealed an alarmingly high prevalence of dysmenorrhea among university students. High levels of stress and early menarche were the potent determinants of moderate/severe dysmenorrhea that disturbs quality of life.

This review considers the conversion of dietary protein and amino acids into chicken-meat protein and seeks to identify strategies whereby this transition may be enhanced. Viable alternatives to soybean meal would be advantageous but the increasing availability of non-bound amino acids is providing the opportunity to develop reduced-crude protein (CP) diets, to promote the sustainability of the chicken-meat industry and is the focus of this review. Digestion of protein and intestinal uptakes of amino acids is critical to broiler growth performance. However, the transition of amino acids across enterocytes of the gut mucosa is complicated by their entry into either anabolic or catabolic pathways, which reduces their post-enteral availability. Both amino acids and glucose are catabolised in enterocytes to meet the energy needs of the gut. Therefore, starch and protein digestive dynamics and the possible manipulation of this ‘catabolic ratio’ assume importance. Finally, net deposition of protein in skeletal muscle is governed by the synchronised availability of amino acids and glucose at sites of protein deposition. There is a real need for more fundamental and applied research targeting areas where our knowledge is lacking relative to other animal species to enhance the conversion of dietary protein and amino acids into chicken-meat protein.

Meat is a non-vegetarian food and is considered as a good source of quality nutrients. Though meat protein provide the required content of good quality protein for the body, they are also associated with higher cholesterol and fat content, which prove to be a leading cause of serious health issues. This became the primary reason for increase in a shift in demands for plant-based protein source foods. The other reason is environmental impact of animal derived products. Meat analogues are plant-based good quality protein source of food that tastes like meat protein, and texture resemble that of meat. These plant-based meat analogues have some amount of anti-nutrients and allergic compounds, but they can be successfully removed by employing certain processing methods and resemble meat in its functionality properties. This approach of mimicking the plantbased foods to resemble meat involves understanding of the biochemical composition and three-dimensional structure of meat, and replicating those qualities using plant-based ingredients. In the current scenario, the best suitable methods of manufacturing meat analogue are by extrusion and structuring techniques. The meat analogues satisfy the need of meat for both vegetarians and non-vegetarians. This review attempts to outline the different manufacturing processes of meat analogue using plant-based foods, and to analyse the best suitable method.
