White v. sweet potato: A nutritional debate fueled by misinformation, baseless claims and carbohydrate fears. Here’s what the evidence says — and why they both deserve a place in your diet during the holidays and beyond.

Which are really healthier?
Claim 1: Sweet Potatoes are the “superfood.”
If all you want is Vitamin A, then sure, sweet potatoes get the win. But when you pit them against white potatoes for overall nutrition value, it’s a virtual tie.

Claim 2: Avoid potatoes because of the glycemic load.
Worried potatoes will make your blood sugar and appetite spike? Both potatoes and sweet potatoes fall in the middle to high range on the glycemic load scale. Total carbohydrates and calorie intake has a bigger impact on important health markers. Plus, glycemic load is generally irrelevant to health and leanness because your blood sugar’s response to food varies.

Claim 3: Avoid all potatoes because of carbs.
Think the carbs will cause weight gain? Actually, the carbs in potatoes and sweet potatoes are mostly starch and fiber, which help you stay healthy and lean. Potatoes contain beneficial starch, which, like fiber, doesn’t digest at all. Resistant starch and fiber get fermented in the gut, producing short-chain fatty acids. Short-chain fatty acids may keep you fuller longer, act as fuel for healthy gut bacteria, prevent absorption of toxins, decrease inflammation and decrease risk of colon cancer.
