Study shows healthy eating slows biological aging by over two years

New research has found that simple daily habits can slow the body's internal ageing process by more than two years. A study following nearly 2,700 women showed that eating more healthily for six to twelve months reduced biological age by an average of 2.4 years. Biological age measures how well the body's systems are working, and scientists say it predicts lifespan more accurately than a person's actual age.

Experts recommend eating more fruits, vegetables, whole grains, and fish, while cutting back on red meat and added sugars. Regular exercise strengthens the heart, muscles, and mood. Staying hydrated and managing stress through sleep or meditation also help. Genetics explains only around a quarter of how long people live, meaning lifestyle choices carry far greater weight.
