Associations between diet quality, epigenetic aging and epigenome in two population-based cohorts
Eating a healthy diet, in general, was linked to slower biological aging in DNA.
Juliana F. Tavares, Dan Liu et al.
People who score well on one healthy eating scale often do not score well on another. Despite this, most healthy diets were linked to slower signs of biological aging in the body's DNA. Different diets left different marks on DNA, but those marks tended to affect the same body processes. Both groups studied came from Germany. Results may not apply the same way elsewhere.
How much people's top scores overlapped across ten different healthy-eating measures.
Two German cohorts only, links not proof of cause.
