Scientists in Australia ran tests on mice which found a diet of fresh fruit, veg and pulses has more benefits than simply cutting the calories. Cutting down on protein and eating more good carbohydrates could boost health and prolong life, a study suggests.
Tests on mice showed the diet has the same benefits for insulin activity, blood sugar and cholesterol levels as a 40% cut in calories. But unlike such a drastic calorie restriction dieting, it will not pose a risk of loss of bone mass, libido or fertility.
Consuming healthy carbohydrates means choosing foods such as fresh fruits and vegetables, whole grains and pulses, and avoiding refined sugar, white bread and pastries. Good sources of protein include eggs, milk, white meat and soya.
Dr Stephen Simpson, of the University of Sydney, said: “It still holds true that reducing food intake and body weight improves metabolic health and reduces the risk of diseases like Type 2 diabetes, obesity, and fatty liver disease. “However, including modest intakes of high-quality protein and plenty of healthy carbs will be beneficial for health as we age.
“Except for the fanatical few, no one can maintain a 40% caloric reduction in the long-term.” The mice were observed for eight weeks as they ate a range of diets with different protein and carbohydrate ratios in conditions where food was restricted or provided at all times.
