Potatoes are affordable, filling, and nutritious, but their health effects depend on how they’re prepared and eaten. Because they are high in starch, they can quickly raise blood sugar levels, especially for people with diabetes or insulin resistance.
Still, potatoes provide important nutrients like vitamin C, potassium, fiber, and resistant starch that support digestion, heart health, and immunity — especially when the skin is left on. Healthier cooking methods like baking, boiling, or steaming keep these benefits, while fried or heavily processed forms like chips and fries add unhealthy fats, salt, and calories.
In moderation, potatoes can be part of a healthy diet, but portion size and preparation make all the difference.
