Summary: Since the U.S. Institute of Medicine's recommendations on protein and amino acid intake in 2005, new information supports the need for re-evaluation. New evidence includes re-analysis of nitrogen balance data, studies on indicator amino acid oxidation, positive functional outcomes with higher protein intakes, guidance from nutrition societies, and recognition of insufficient amino acid synthesis. The convergence of empirical, theoretical, and clinical evidence suggests that protein and amino acid recommendations may be too low in certain populations.

Summary: This study aimed to investigate the relationship between dietary intake of branched-chain amino acids (BCAAs) and hypertension risk in the Chinese population. The findings showed that dietary BCAAs intake was positively associated with both systolic and diastolic blood pressure values, as well as an increased risk of hypertension.

Summary: This study evaluated the association between postdiagnostic BCAA intake and CRC-specific mortality and overall mortality among nonmetastatic CRC patients. The findings suggest positive associations between higher intake of dietary BCAAs and risk of all-cause mortality in CRC patients, with no statistically significant associations observed for CRC-specific mortality. Further research is needed to confirm these findings and elucidate potential mechanisms underlying this association.

Summary: The study found that high-SAA diets are associated with increased risk for diabetes mortality, and lowering intake towards Recommended Dietary Allowance levels could lead to reductions in lifetime risk.

Summary: The study found that higher consumption of specific dietary amino acids was associated with poorer liver health, as indicated by liver fat content, liver iron concentration, and ferritin levels. The intake of these amino acids was positively correlated with markers of glucose metabolism.

Summary: This study characterizes habitual amino acid intakes in the US population and finds that the intakes exceed the recommended minimum requirements. Furthermore, there are differences in amino acid intakes among different races and genders.

Summary: Animals regulate protein and fat intake for optimal health and survival, with honeybees actively adjusting their lipid intake to achieve balance. High-fat diets can lead to increased abdominal fat in worker bees, but do not necessarily result in higher mortality rates. Honeybees' food consumption increases with higher fat content, affecting their nutritional status and behavior.

Summary: This study found a significant association between higher dietary intake of branched-chain amino acids (BCAAs) and a reduced risk of postmenopausal breast cancer, especially for valine, leucine, and isoleucine.

Summary: Maternal dietary intake is associated with fetal alcohol spectrum disorders (FASD). A study conducted in South African communities with high rates of FASD found that more than 50% of pregnant women had inadequate intake of several vitamins and minerals, particularly in alcohol-consuming women. Inadequate maternal dietary intake may increase the risk of poor infant growth and likelihood of FASD.

Summary: Current estimates of protein requirements in children are largely based on the nitrogen balance technique, which may underestimate protein needs. Recent advances in stable isotope techniques suggest protein requirements may be up to 60% higher, especially in children engaging in higher levels of physical activity.

Summary: Scientific studies show that most vegetarians meet the total protein requirements, but little is known about their amino acid intakes. This study aimed to assess the dietary intake and serum amino acid levels of prepubertal children on vegetarian and traditional diets, and their relationship to bone metabolism markers. Results indicate that vegetarian children have significantly lower protein and amino acid intake, as well as lower serum levels of certain amino acids, compared to omnivores.

Summary: This study aimed to assess the association between diet quality and training-induced muscle mass in elite male athletes. The results showed that low-carbohydrate diet was associated with lower muscle mass in aerobic male athletes. Adequate protein intake was found to be beneficial for muscle mass gain in anaerobic male athletes. Increased intake of specific amino acids, such as isoleucine and histidine, was positively correlated with muscle mass gain, while higher valine intake was negatively associated with muscle mass among anaerobic male athletes.

Summary: This study found an inverse association between monounsaturated fatty acid intake and hepatocellular carcinoma (HCC) risk, and a direct association between total polyunsaturated fatty acid intake and HCC risk. Omega-6 PUFA intake was directly associated with HCC risk, while long-chain omega-3 PUFA intake was inversely associated with HCC risk. No significant association was observed for saturated fat and HCC risk.
