That crispy plate of French fries might be tempting, but eating them too often could harm your health. A recent international study, published in The British Medical Journal, reveals that having three or more servings of French fries a week can increase the risk of type 2 diabetes by up to 20 percent. This research analyzed dietary data from more than 205,000 people over nearly 40 years and found the link strongest with fried potato products. Interestingly, baked, boiled, or mashed potatoes did not show the same risk.
Why French Fries May Raise Diabetes Risk
Potatoes are naturally rich in fibre, potassium, and vitamin C, but frying changes everything. Deep frying adds excess oil, increasing calorie and fat content, and produces harmful compounds that may affect metabolic health. Store-bought fries also tend to have high salt levels, which can raise blood pressure if eaten regularly.
How Diet Influences Type 2 Diabetes
Type 2 diabetes develops due to a mix of genetic, lifestyle, and dietary habits. While no single food causes it, regularly consuming fried, high-carb foods like French fries can contribute to a higher risk. Experts suggest eating more whole grains, legumes, vegetables, fruits, and lean proteins while cutting down on fried and highly processed foods.

Smarter Food Swaps for Potatoes
Researchers found that replacing three servings of potatoes a week with whole grains lowered diabetes risk by 8 percent. However, swapping potatoes for white rice actually increased the risk, proving that not all substitutions are healthy.
