Demystifying Starch in Vegetables
Starch is a complex carbohydrate that the body breaks down into glucose for energy. While vegetables are generally healthy, their carbohydrate content is a key factor in dietary planning, particularly for those on low-carb diets or managing blood sugar. The distinction between 'starchy' and 'non-starchy' is crucial. Vegetables like potatoes, corn, and peas are high in starch and calories, while many others, such as leafy greens and bell peppers, contain much less. These 'non-starchy' options are prized for their high volume, fiber, and nutrient density, making them excellent choices for filling up without loading on calories.
