A study, published in September 2023, explored the impact of different diets on biological aging, which is a measure of how fast your body is aging based on DNA methylation. They used various DNA methylation-based aging clocks to assess this in 256 participants with abdominal obesity or dyslipidemia over an 18-month period. The participants were divided into three diet groups: one following healthy dietary guidelines, one on a Mediterranean (MED) diet, and one on a polyphenol-rich, low-red/processed meat Green-MED diet. The Green-MED diet included walnuts, green tea, and Mankai, a green plant, with higher polyphenol content. The researchers found that participants who adhered more closely to the Green-MED diet had a slower rate of biological aging, as indicated by specific methylation aging clocks known as Li and Hannum methylation age. This slowing of biological aging was associated with increased intake of Mankai and green tea , and it corresponded...
