Eating a vegan diet may reduce a person’s biological age, research suggests.

A study looked at 21 pairs of identical twins, aged 39; one of each of the twins ate a vegan diet, while the sibling ate an omnivorous diet.

After eight weeks of a plant-based diet, the study found the participants had a “younger” heart, liver, inflammatory and metabolic system.

These changes were not seen in the twins whose diet included meat, eggs and dairy products.

Those who ate a vegan diet also lost 2kg more on average than those who did not, probably because of differences in the calorie content of meals provided during the initial four weeks of the study.

According to experts, the weight loss could have contributed to the observed differences in biological age between the groups.
