Science Daily Article: Five daily portions of fruits and vegetables may be enough to lower risk of early death

A study was done by a team of researchers in China and the United states on the health benefits of five servings of fruits and vegetables a day, compared to a study done by BMJ’s Journal of Epidemiology and Community health; saying the average person needs seven servings of fruits and vegetables per day. These servings are suggested to lower the risk of early death from diseases like cancer and cardiovascular disease. The team of researchers in China and the United states believed five servings a day was needed (sciencedaily) and that seven had no additional benefits. They looked at the results of sixteen studies of 833,234 people and 56,423 deaths (sciencedaily). The risk of death did not lower further when the servings of fruits and vegetables exceeded five per day, but according to Barrett’s law #7 correlation is not causation, so this does not definitely mean that higher servings will not do the body any good. The textbook does have information on Vitamins E, C, and beta-carotene possibly lowering the risk of heart disease, and these can be obtained from fruits and vegetables (pg.399). A specific amount of these vitamins is not mentioned in the book. I think later versions of Lifespan Development will include information on the amounts of these vitamins.
