The potato is small enough to fit inside a person’s hand yet contains enough nutrients to whittle waistlines and lower blood sugar in adults with Type 2 diabetes. Yet, despite the fact that potatoes – particularly the skins – are packed with health-boosting nutrients, they routinely get a bad rap among dieters.
That may soon change, thanks to new research by Neda Akhavan, assistant professor in the Department of Kinesiology and Nutrition Sciences within UNLV’s School of Integrated Health Sciences. Akhavan recently presented her findings on the cardiovascular benefits of potatoes for those living with Type 2 diabetes to the Alliance for Potato Research and Education.
“I like doing research on food items that are highly stigmatized in the nutrition world,” she said. “Most people associate the potato as something that is mostly fried or has a lot of fat, and we wanted to shine a light on how a potato – when prepared properly – can be both functional and healthy.”
Putting Potatoes to the Test
Akhavan enlisted 24 participants for the study, all of whom had Type 2 diabetes that was well controlled with medication. Funded by the Alliance for Potato Research and Education, this is believed to be the first study of its kind to scientifically measure the cardiovascular benefits of potatoes for adults with diabetes.
Participants in the study group were each given a pre-prepared baked potato with the skin measured to 100g, with only 20 grams of carbohydrates, roughly enough to fit in one hand to incorporate as a snack or side with meals daily. The control group was given a similar potion of white rice with the same number of calories and carbohydrates. The study ran daily for 12 weeks, which is considered the minimum time needed to see changes in indices of glycemic control and cardiometabolic health.
Study participants were permitted to add herbs or spices to the potatoes, or up to ½ tbsp of butter, but they were advised not to fry their potato.
