Fried potatoes, under the magnifying glass: frequent consumption increases the risk of type 2 diabetes. The healthiest alternatives for your plate

A new international study highlights that frequent consumption of fried potatoes – three or more servings a week – can significantly increase the risk of type 2 diabetes. An international team of researchers, who also included an specialist from the University of Cambridge, analyzed the connection between the consumption of fried potatoes and the increased risk of diabetes.

The results indicated an increase of over 20% of the risk for people who ate fried potatoes at least three times a week. Instead, this risk was not observed in those who consumed potatoes in the oven, boiled or puree.
Dr. Faye Riley, from the Diabetes UK organization, said, quoted by BBC: “This research shows that the connection between potatoes and type 2 diabetes is not as simple as it may seem.”.
The analysis was based on data from studies that followed the health status of over 205,000 US medical staff for almost four decades. During this period, the participants periodically completed food questionnaires, and the researchers documented over 22,000 cases of type 2 diabetes.

How to influence the consumption of fried potatoes The risk of type 2 diabetes: healthy studies and alternatives
“The association between high potato consumption and an increased risk of type 2 diabetes is mainly determined by the consumption of fried potatoes. A higher intake of fried potatoes – but not of baked potatoes, boiled or puree – has been related to an increased risk of type 2”wrote the authors of the study published in The British Medical Journal. The condition can also increase the risk of heart attack, stroke or kidney injury.
The researchers also found that the replacement of three portions of potatoes per week with whole grains reduces the risk of type 2 diabetes by about 8%. In contrast, replacing potatoes with white rice has been associated with an increased risk. White rice, basic food in Romania is considered a real danger in the plate.
Link between fried potatoes and type 2 diabetes: Recommendations for a healthy diet
Dr. Faye Riley, research communication coordinator at Diabetes UK, explained: “Type 2 diabetes is a complex condition, influenced by many factors, including genetics, age and ethnic origin. Eating is only a part of the story, but this study suggests that the way of preparing food can count. The results strengthen the recommendation to prioritize whole grains and to reduce the consumption of fried foods or to reduce a balancing,”
The findings, therefore, emphasize that the way foods are prepared is essential for their general health risks or benefits, as said Seyed Mohammad Mousavi, the main author of the study and postdoctoral researcher at the Harvard Public Health School: Harvard: “Not all potatoes are the same. Even a small amount of fried potatoes, less than one serving per week, is associated with a higher risk of type 2 diabetes.”
Fried potatoes vs. Bakes: How does the method of preparation influence the risk of type 2 diabetes
Frying potatoes are not only a crunchy delicacy, but also a caloric bomb that can endanger health. Unlike boiled or baked potatoes, which keep their nutritional properties almost unchanged, the fries absorb unhealthy fats from high and saturated fat oils. These fats influence how the body manages insulin, key hormone in regulating blood sugar levels. When cells become less insulin sensitive, insulin resistance, an important step towards type 2 diabetes.
“The frying increases dramatically the caloric content of the potatoes, through the fats they absorb. The frequent consumption of fried potatoes can favor weight gain, a major factor in the appearance of diabetes.” Explains Candida Rebello, director of the Nutrition and Chronic Diseases of the State University of Louisiana, who did not participate in the study.
The history of potato frying also reflects changes in the food industry. The data collected between 1984 and 2021 capture the transition from the beef used in the 1980s, to the partially hydrogenated oils from the 1990s-a major trans fat source, eliminated only after 2018. Today, fast food chains prefer vegetable oils such as canola, sunflower, soy or peanut, but it remains for the health.
When they become unhealthy boiled, baked or mashed potatoes: ingredients and preparation increase the risk of diabetes
But also how we prepare potatoes in the oven, boiled or puree can significantly influence the caloric intake and effects on health, especially when added ingredients such as butter, cream or cheese, which increase the content of fats and sugars, amplifying the risk of metabolic imbalances and type 2 diabetes.
“What do people add to baked potatoes? Butter, bacon, cheese, cream. And we don't even know if they ate them with shell!”draws the attention of Shannon Gonyean, professor of nutritional sciences at Texas Tech University, who did not attend the study, quoted by NBC News.
This question is important, because potatoes are a valuable source of fiber, essential for blood sugar control. In their natural form, without frying or fat, baked, boiled or pure potatoes can be good health allies, offering potassium, a mineral that helps regulate blood pressure.
“Potatoes can be considered healthy as long as they are not fried and do not add large amounts of fat.”explains Gonyean.
However, home preparation of fried potatoes with healthy oils, such as olive or avocado, can reduce the risk of diabetes, compared to fast food variants, Mousavi points out. Moreover, the replacement of potatoes with whole grains, such as Farro, whole bread or whole pasta, can have an even stronger impact, thanks to the lower glycemic index and the beneficial effect on the blood sugar level.
Conclusion: A balanced diet and healthy potato preparation reduce the risk of type 2 diabetes
The specialists, however, also emphasize that health does not depend on a single food, but on the whole of the daily diet. Therefore, nutritionists recommend coloring your plate with an explosion of fresh fruits and vegetables, along with whole grains and quality proteins-such as fish, beans or nuts-for a balanced diet that really supports your well-being.
The results of the new study confirm that the increased risk of type 2 diabetes is mainly linked to the consumption of fried potatoes, and not to the baked or boiled. Replacing the weekly portions of fried potatoes with whole grains or even boiled, baked or pure potatoes can significantly reduce the risk of this chronic condition. To prevent type 2 diabetes and maintain a healthy diet, experts generally recommend reducing the consumption of fried and processed foods. Adopt a balanced lifestyle and pay attention to how you prepare your food to protect your long-term health.
