Diet change tied to ‘younger’ biological age in older adults after 4 weeks
Researchers found this changing your diet It can slow the aging process in as little as a month – even later in life.
Researchers from the University of Sydney assigned 104 participants, aged 65 to 75, to one of four diets. Two of the diets were omnivorous and included protein from both animals and plants. Two contained 70% of the protein from plant sources.

According to the report, biomarker profiles are “generally considered a better indicator of overall health and Potential lifespan longer than chronological age“
Scientists have found that older adults who eat diets rich in complex carbohydrates and plant-based foods have reduced biological age.
After four weeks, the scientists found that participants’ biological ages had decreased in three of the four diet groups. The biological ages of dieters who ate only high-fat meat “did not change significantly.”

Study, The article “Short-Term Dietary Intervention Alters Physiological Profiles of Aging,” published in the journal Aging Cell, concluded that the most significant improvements came from “diets.” rich in complex carbohydrates and plant-based ingredients.”
A study at the University of Sydney found that participants who consumed a high-fat, omnivorous diet showed no change in their biological age, while all other types of diets reduced their age.
