A recent study suggests that baked and roasted potatoes can be beneficial for those with type 2 diabetes by aiding in maintaining healthy blood sugar levels and promoting weight loss. The research compared baked potatoes with an equivalent portion of white rice, concluding that potatoes, when cooked properly, can have positive effects on individuals with diabetes. It is important to note that fried potatoes, such as french fries or potato chips, are not considered healthy due to the addition of unhealthy trans fats and extra calories. Michelle Routhenstein, a preventive cardiology dietitian, explained how the frying process can turn a healthy potato into a nutritional problem, causing inflammation and other health risks.
The study was led by Neda Akhavan, PhD, RD, and involved 24 participants with type 2 diabetes. Half of the participants were given baked potatoes as a snack or side dish daily for 12 weeks, while the other half consumed an equivalent amount of white rice. The results showed that those eating baked potatoes experienced improvements in fasting blood glucose levels, waist circumference, resting heart rate, and body composition compared to the control group. It is important to highlight that the study results have not yet been published in a peer-reviewed journal, although the Alliance for Potato Research and Education was a collaborator.
While potatoes are often considered an unhealthy food choice, depending on their method of preparation, baked or roasted potatoes can offer numerous health benefits. Routhenstein emphasized the importance of avoiding fried potatoes, as they introduce unhealthy trans fats and extra calories that can worsen overall health and heart health. Baking or roasting potatoes is the healthiest way to prepare them, as it retains their nutrient content, including potassium, vitamin B6, folate, and dietary fiber. Various toppings, such as plain Greek yogurt, non-starchy vegetables, lean proteins, fresh herbs, and avocado, can enhance the flavor of a baked potato and are healthy for individuals with diabetes.
Boiling potatoes, while a better alternative to frying, is not as healthy as baking or roasting. Akhavan explained that boiling can cause the loss of minerals, such as potassium, and decrease the fiber content of the potato. Furthermore, boiled potatoes can leach into the cooking water, resulting in nutrient loss. Compared to white rice, which can spike blood sugar levels due to its refined nature, brown rice or whole grain pasta are better alternatives as they offer higher fiber content and essential nutrients. Portion control is emphasized for potatoes and rice, along with the overall diet composition throughout the day. It is also recommended to consume the potato skin, as it contains resistant starch that supports gut health and improves blood sugar and lipid profiles.
In conclusion, the study highlights the benefits of baked and roasted potatoes for individuals with type 2 diabetes. The proper preparation of potatoes is crucial, as frying can introduce unhealthy elements that are detrimental to health. Baking or roasting potatoes retains their nutrient content and offers various health benefits, including improved blood sugar levels and weight management. It is essential to consider the method of preparation and overall diet when consuming potatoes and rice, as well as the portion sizes. Including potato skins in the diet can also maximize the nutritional benefits of this vegetable and support overall health.
