How to reduce a person's biological age - a study
Australian researchers from the University of Sydney have found that changing one's diet for four weeks can reduce the estimated biological age in older adults. The experiment involved 104 people aged 65 to 75. The most pronounced result was seen in the group with low fat and high carbohydrate intake.
Australian researchers from the University of Sydney, led by Dr. Caitlin Andrews, have discovered that a four-week dietary change can lower the estimated biological age in older adults. The experiment involved 104 Australians aged 65 to 75. Participants followed one of four diet plans. Protein made up 14% of total calories in all menus, but its sources varied: in one group, half of the protein came from plant-based foods, while in another, it was 70%. Researchers also varied the ratio of fats to carbohydrates. The effect was assessed using 20 biological markers, including insulin, cholesterol, and C-reactive protein levels. After four weeks, the estimated biological age decreased in three out of four groups. The most significant result was observed in the group with lower fat and higher carbohydrate intake: 53% of energy came from carbohydrates and 28–29% from fats. No changes were found in participants on a high-fat diet with an equal ratio of plant and animal protein. Researchers note that it is not yet known how long this effect lasts, and the results do not prove that such a diet extends lifespan or reduces the risk of age-related diseases.
