Are French Fries Really That Unhealthy? Here’s What Science Says

French fries are, without a doubt, one of the most popular foods in the US. According to Talker Research, Americans consume around 5.6 billion pounds of them every year. But new research suggests that eating fries too often could carry serious health risks.

A study from the Harvard T.H. Chan School of Public Health, published in The British Medical Journal, found that eating French fries three or more times per week was linked to a 20 percent higher risk of developing type 2 diabetes. To reach these findings, researchers analyzed data from more than 205,000 adults across the US.

Does that mean fries should be off the menu altogether? Not necessarily. The good news: other potato preparations, like baked, boiled, or mashed, did not show a significant link to type 2 diabetes. This suggests the problem isn’t potatoes themselves, but the deep-frying process.

Are French fries always unhealthy?

We’ll put you out of your misery: no, French fries aren’t always unhealthy. It all comes down to how they are cooked. 

Potatoes themselves are highly nutritious. As a root vegetable, they’re a good source of fiber, carbohydrates, vitamin C, magnesium, and potassium. They also provide antioxidants like flavonoids and carotenoids. In fact, research suggests that eating more potatoes may even help reduce the risk of certain diseases.

“I often tell clients to consider swapping some of the rice or pasta that they eat each week for potatoes,” nutritionist Sophie Trotman told The Telegraph. “Potatoes contain a lot of micronutrients, as well as a good amount of fiber and resistant starch, both of which are crucial to gut health and may help prevent bowel cancer.”

The healthiest ways to enjoy potatoes are boiled, mashed, roasted, air-fried, or baked. The least healthy? Processed and deep-fried versions, such as those from fast-food chains or the frozen aisle. Processing strips away many of the natural nutrients, while frying adds extra fat and calories.

The good news: you can still make French fries in much healthier ways.
