A study has found that following a vegan diet for just one month was linked to slower signs of aging in the body. The finding highlights how a relatively short dietary change may affect markers associated with the aging process.

The result comes as veganism remains a minority lifestyle in the United States. Just 1 percent of Americans identified as vegan in 2024, according to the information accompanying the report.

The findings add to continuing interest in the relationship between diet and biological aging, while underscoring that the study focused on a limited one-month period rather than long-term dietary habits.
