Effect of a Pulse-based USDA-diet on Healthspan

Status Active, not recruiting

Clinical Trial Summary

Plant-based diets are naturally low in Methionine (Met), and also low in precursor molecules (e.g L-carnitine, choline, betaine, etc.) producing microbiota-mediated proatherogenic TMAO. Among plant proteins, pulses are rich in micronutrients, and dietary fibers, making them ideal for microbiome stimulating, nutrient-dense, healthful dietary patterns. However, daily pulse intake remains low at 8% in America despite recommendations by DGA, a resource to guide health promotion across communities. A significant body of preclinical data, waiting to be translated to humans, suggests that dietary Met restriction can trigger beneficial metabolic and anti-inflammatory adaptations leading to improved chronic health and longevity. The central hypothesis is that a pulse-protein-based healthy diet can be simultaneously equivalent to omnivorous diets in protein content to prevent muscle wasting in older adults and yet naturally lower in Met and TMAO to improve glycemic control, body composition, and immunometabolic flexibility to reduce the risk of chronic diseases and improve healthspan. Using the investigator's published workflow related to all proposed aspects here, the goal is to systematically elucidate for the first time the effects of a lacto-vegetarian DGA feeding pattern with pulses as the primary protein source on a comprehensive panel of ~500 traditional and next-generation biomarkers of health, and assess the role of the gut microbiota in mediating such effects.
