Potatoes fall in the high GI category. A cup of them can affect your blood sugar in the same way a can of soda would.
Are potatoes a low glycemic food?
Potatoes by themselves have a high Glycemic Index (GI). High glycemic index foods are a concern because they are digested quickly causing spikes in blood insulin levels, which increases the risk of diabetes and heart disease.
How do you lower the glycemic index of potatoes?
Cooking a potato makes the starch more digestible, which raises the GI. After cooling, the potato becomes less digestible again, which may lower the GI. The most healthful way to cook potatoes is to boil, steam, or microwave them without adding other ingredients.
What potato does not raise blood sugar?
Another important consideration is the cooking process. When boiled, sweet potatoes are a low glycemic index (GI) food, meaning they won't spike your blood sugar as much as regular potatoes, according to research published in the Journal of Nutrition and Metabolism.
Are potatoes high glycemic or low glycemic?
Since the starch in potatoes is rapidly digested, the glycemic index of potatoes can be almost as high as that of glucose alone. The glycemic index of glucose is 100 points; potatoes are usually listed as being in the high 80s or low 90s. However, potatoes have a higher GI score than table sugar.
