If you love french fries, then we have some bad news for you.

One Harvard professor says the magic number is only six. If you're looking to scoff down an entire plate then it looks like you're out of luck.

Eric Rimm, a professor in the departments of epidemiology and nutrition at the Harvard T. H. Chan School of Public Health, tells the New York Times that potatoes are near the bottom of the list when it comes to healthy vegetables.  

A study last year from the American Journal of Nutrition said that a diet heavy in fried potatoes could lead to obesity, diabetes and cardiovascular disease.

So yes, french fries aren't that great for you. Did we need a Harvard professor to tell us this?

The NY Times says that Americans eat an average of 115.6 pounds of white potatoes a year, Two-thirds are in the form of fries, chips and other processed products, according to Agriculture Department statistics.

The lesson here is either share your fries with a few people, or just order a side salad.
