In 2002, the National Academies' Institute of Medicine released a report that recommended:
Adults should get 45 percent to 65 percent of their calories from carbohydrates, 20 percent to 35 percent from fat, and 10 to 35 percent from protein.
This is largely a consensus view of the science.
(Dr Caldwell Esselstyn Jr, on the other hand, recommends that no oils should be added to food to avoid heart disease, which might be seen in contradiction to this consensus view.)
Is there sufficient nutritional and epidemiological evidence to support the Institute of Medicine's view about the level of calories that should be obtained from fat for a healthy diet?
