Sweet potatoes edge white potatoes for everyday nutrition

Health Points

• Sweet potatoes supply more vitamin A and fiber per serving than standard potatoes.
• Both tubers deliver potassium and complex carbohydrates in similar amounts.
• Preparation method influences the overall nutritional value of either option.

Nutritionists often receive questions about which potato deserves a regular place on the dinner table. The short answer is that each variety offers distinct benefits, so the best choice depends on personal dietary goals.

“Sweet potatoes are an excellent source of beta-carotene, which the body converts to vitamin A,” registered dietitian Laura Simmons explains.

White potatoes, on the other hand, provide slightly more potassium—an important mineral for blood-pressure regulation. Both vegetables supply steady energy through complex carbohydrates, making them suitable choices for active adults.

“It’s not about declaring a single winner,” Simmons adds. “It’s about how you prepare them and what else is on the plate.”

Roasting or baking preserves nutrients better than deep-frying. Adding a small amount of healthy fat, such as olive oil, can improve absorption of fat-soluble vitamins found in sweet potatoes.

Portion size remains key. A medium potato of either type counts as one serving of vegetables and fits comfortably within a balanced meal plan for adults over forty.
