Traditional use: In some cultures, sweet potato is used topically for skin conditions. But eating them works from the inside out.
The Best Way to Eat Sweet Potatoes
Preparation Methods Ranked by Health Impact
Method Health Impact Notes
Baked/roasted Excellent Preserves nutrients; no added fat needed
Boiled/steamed Excellent May lower glycemic response
Mashed (with skin) Very good Keep the skin for fiber
Roasted fries Good Use minimal oil; bake, don’t fry
Fried (sweet potato fries) Moderate Adds significant fat and calories
Candied/casserole with marshmallows Poor Adds sugar, diminishes health benefits
The Skin Matters
Eat the skin. It contains significant fiber, vitamins, and antioxidants. Just scrub well before cooking.
What Doctors Warn About
1. Portion Control Matters
A medium sweet potato is one serving. Eating multiple large sweet potatoes in one sitting can spike blood sugar—especially if you’re diabetic.
2. Avoid “Candied” Versions
Traditional holiday sweet potato casseroles with marshmallows, brown sugar, and butter turn a healthy vegetable into a sugar-laden dessert.
3. Watch the Toppings
Sour cream, butter, brown sugar, and marshmallows add significant calories, fat, and sugar. Try:
Plain Greek yogurt instead of sour cream
Cinnamon instead of sugar
A drizzle of tahini or almond butter
4. Kidney Stones? Consider Moderation
Sweet potatoes are high in oxalates, which can contribute to calcium-oxalate kidney stones in susceptible individuals. If you have a history of stones, moderate your intake.
