Six diets were evaluated for their effect on speed of aging, plant-based and health-consci

Well SupportedThe plant-based diet was associated with the highest reductions in the speed of aging in general and twin comparisons.

Well SupportedAll dietary patterns evaluated, except for the high fast-food, low fruits and vegetables pattern, reduced the speed of aging compared to the high fast-food diet.

Partially SupportedDiet significantly influences the speed of aging, even in individuals in their early 20s.

Partially SupportedStudy authors cautioned against over-interpreting twin-pair analysis results due to the small number of twins with distinct dietary patterns.
