Small Meat Substitutions May Extend Healthspan and Trim Grocery Bills
Australian researchers studied about 100 adults aged 65–75 on four meal plans that swapped some meat for plant proteins and fiber for a month; all groups lost roughly four pounds, but only the plant-forward diets improved biological age (per the Klemera–Doubal method) and health markers, while the high-meat plan showed no biological-age benefit. The study suggests modest meat reduction and greater plant-protein/fiber intake can support aging healthfully without requiring a vegetarian diet; results are preliminary.
