Ten Healthy Eating Patterns Linked to Slower Biological Aging
Researchers led by a team from Germany's German Centre for Neurodegenerative Diseases studied diet and biological aging in 6,470 people aged 30 and over.
They compared participants' scores on 10 dietary patterns with blood markers linked to biological age, which can differ from a person's age in years.
Healthier eating was linked to slower biological aging across the patterns, which included Mediterranean, Nordic, DASH and MIND diets.
Two measures focused on unhealthy plant-based eating and inflammatory foods; lower scores on those measures were linked to slower aging.
The researchers said many of the diets were linked to changes in the same biological pathways, while some had distinct associations, such as DASH with heart-related aging and MIND with cognition and memory.
The findings matter because slower biological aging may be relevant to the risk of age-related diseases, including dementia and cardiovascular disorders, but the study does not prove diet caused the effect.
The team found broadly similar associations in a separate group of 1,034 people, and further studies could examine how dietary changes over time affect biological aging.
A study linked 10 established healthy eating patterns with slower biological aging.
Researchers analyzed data from 6,470 people aged 30 and older, using blood biomarkers based on DNA methylation.
The associations appeared across all the dietary patterns, though some were stronger than others.
Researchers said more than 70 percent of the affected biological pathways were shared across the diets.
The study found an association, not proof that the diets directly cause slower aging.

What people are saying
The effects are not massive, but they are measurable and relevant for prevention
According to our data, various dietary patterns are associated with slower aging, some more, some less.
More than 70 percent of the affected biological pathways were shared across all diets
