How French Fries Clog Your Arteries

French fries are a bomb of trans fat and salt. Frequently eating french fries heightens the risk of high blood pressure, obesity, and diabetes--all of which are precursors to heart disease, says Harvard Health Publishing. In that sense, french fries can threaten peoples' lives.

In 2017, scientists studied over 4,400 people who ate potatoes. Published in the American Journal of Clinical Nutrition, the study reported a higher risk of death from french fries. Potatoes didn't increase the mortality rate, but after they were fried, participants were more likely to contract heart disease.
