Cutting down on protein and upping consumption of carbohydrates may be the key to living a longer, healthier life, new research suggests.
In tests on mice, changing the mix of protein and carbs produced the same benefits as reducing calorie consumption by 40 per cent.
Previous research has shown that strict calorie restriction can improve metabolism and extend lifespan across a wide range of species.But such a drastic strategy would be challenging for most people and may harm health.
Eating smaller amounts of high quality protein - and a lot of healthy carbohydrates - might prove more practical for humans, scientists believe.
Good sources of protein include eggs, milk, white meat and soya.
Consuming healthy carbohydrates means choosing foods such as fresh fruits and vegetables, whole grains and pulses, and avoiding refined sugar, white bread and pastries.
