A new paper by over 20 protein experts examines widely held propositions about dietary protein, concluding that some science is insufficient or not robust enough to support certain claims. Key findings include the importance of protein quality, individual essential amino acids, and nuance in high-protein intake during weight loss.
Researchers analyzed correlations between fruit fly and human data to identify key metabolites impacting lifespan. Threonine was found to extend lifespan in flies and show promise as a therapeutic target for aging interventions.
Research at Massachusetts General Hospital has identified plasma biomarkers Tau-PT217 and Tau-PT181 as predictors of postoperative delirium. High preoperative concentrations of these biomarkers are associated with increased risk, suggesting a potential early warning sign for patients.
Researchers at Monash University have discovered that reducing two essential amino acids, threonine and tryptophan, can lead to increased calorie burn and improved health in young mice. A low-threonine diet also protected obese mice from developing type 2 diabetes.
Researchers at the University of Illinois investigated threonine biomass as a lower-cost alternative to fish meal for pig diets. Threonine biomass was found to contain more crude protein and have higher protein digestibility compared to fish meal, making it a promising source of protein for pigs.
University of Illinois researchers found that dietary fiber, particularly pectin, negatively impacted birds' ability to digest nutrients, while adequate threonine levels improved growth performance and intestinal morphology. Chicks fed high-threonine diets showed increased cytokine responses to coccidiosis infections.
A study at Michigan State University reveals a potential new way for plants to fend off pests through starvation. The research focuses on the enzyme threonine deaminase (TD2), which breaks down a key nutrient in caterpillars' stomachs, starving them.
