Optimal fruit and veg intake is a pound a day, says meta-study
People who want to live as long as possible should eat about a pound a day of fruit and vegetables. Chinese and American nutritionists draw this conclusion in an article published in the British Medical Journal. The researchers gathered data from 16 big epidemiological studies and re-analysed them. They had data on 833234 people.
Fruit and vegetables
Some studies express fruit and vegetable intake in servings; others use grams. For both vegetables and fruit 1 serving is about 80 grams.
Optimal health protection was obtained by eating 5-6 servings amounting to about half a kilogram per day. Higher intake does not lead to a further reduction in mortality risk.
"In addition, different types of fruit and vegetables might have different effects on cancer risk. Future studies are needed to be more specific about types of cancer and the role of different groups of fruit and vegetables."
