Potatoes

Potatoes are a dietary staple, but there have been times when this carb-rich food has been maligned as unhealthy, due to how it’s broken down by the body. The carbohydrates in potatoes are quickly digested, meaning there’s a more immediate effect on raising our blood sugar—known as having a high glycemic index. Some dietary scientists have argued that foods with a high glycemic index are inherently less healthy and can contribute to obesity and other health problems. But there is still uncertainty about whether the glycemic index is a useful rule of thumb for the average person’s diet, and more recent studies have shown that potatoes aren’t uniquely less filling than other carbs, nor do they contribute to an early death.
A caveat here, though: While potatoes in general may not be unhealthy, dunking them in a deep fryer definitely isn’t the best way to eat them. And you can always afford to mix in some other non-starchy carbs into your diet.
