Researchers at La Trobe University in Australia have found for the first time in a rigorously controlled clinical trial that people with diabetes don’t need to avoid potatoes, according to a report by Dr. Kamal Kant Kohli, published in Medical Dialogues.
It is often said that potatoes with high glycemic index should be avoided by diabetics as they may adversely affect blood sugar. But the study indicates that glycemic index is not an accurate surrogate for an individual’s glycemic response (GR) to a food consumed as part of an evening meal.
The findings show that participants had a better ‘nocturnal’ glycemic response when they ate a mixed meal with skinless white potatoes compared to an isoenergetic and macronutrient-matched mixed meal that included a low GI carbohydrate food — basmati rice.
People with type 2 Diabetes (T2D) are frequently told to avoid eating potatoes, and other high Glycemic Index (GI) foods, because of the longstanding perception that these foods make it difficult to control blood sugar levels. This is especially problematic during the night when blood sugar tends to spike — a phenomenon that has been associated with cardiovascular disease and endothelial dysfunction.
The researchers concluded that potatoes are a vegetable that is sustainable, affordable and nutrient-dense, and thus, they can play an important role in modern diets irrespective of metabolic health status.
The study has been published in Clinical Nutrition.
