At first, sweet potatoes and white potatoes seem almost identical in calories and carbohydrates. But once their nutrient profile is examined closely, the differences begin to show.
Sweet potatoes stand out because of their rich antioxidant content and high vitamin A levels. Their orange, purple, or reddish flesh comes from compounds like beta-carotene and anthocyanins, both known for supporting immunity and reducing oxidative stress.
Aman Puri, Founder of Steadfast Nutrition, explains, “Sweet potatoes are typically red or purple in colour due to the presence of the pigment anthocyanin — an antioxidant that enhances their nutritional value. They’re also packed with phenolic compounds, carotenoids, and vitamins A, C, and E, which support vision, immunity, and skin health.”
White potatoes, meanwhile, are often unfairly dismissed. They contain more potassium than sweet potatoes and are naturally rich in vitamin C. Potassium is especially important for maintaining blood pressure, muscle contraction, and heart function.
One medium sweet potato can provide more than the daily recommended intake of vitamin A, while white potatoes offer a stronger potassium punch. That means neither is “empty calories,” despite what diet culture often claims.
