You should only eat 6 fries at a time as proper portion

Bad news for those who love fries.

A Harvard professor says you should only eat six fries at a time as a proper portion.

Eric Rimm made the declaration in an article for the New York Times.

Rimm, who works at Harvard's Nutrition Department, says fries are "starch bombs."

A recent study found that people who ate fries two or three times a week had higher risks of diabetes, obesity and cardiovascular disease.

To avoid going over the six-fry limit, doctors recommend that you share a plate of fries with friends, alongside healthier foods.
