Researchers from the University of Sydney found that dietary changes can reduce biological age in older adults within four weeks. The study, published in Aging Cell, assigned 104 participants aged 65-75 to one of four diets: two omnivorous (high-fat or high-carb) and two semi-vegetarian (high-fat or high-carb). All diets derived 14% of energy from protein. Biological age, measured through 20 biomarkers including cholesterol and insulin levels, improved in three of the four diet groups. Only the high-fat omnivorous diet showed no meaningful change. The most significant improvements were seen in diets rich in complex carbohydrates and plant-based components. Researchers cautioned that the results are preliminary but suggest dietary interventions may influence aging processes even in later life.
