What Makes a Vegetable Low in Starch?
Starch serves as a complex carbohydrate that plants use for energy storage. When starchy foods are consumed, the body breaks the starch into sugar molecules, which may affect blood sugar levels. Vegetables are commonly categorized into starchy and non-starchy types. Non-starchy vegetables contain less starch, carbohydrates, and calories compared to starchy vegetables, while offering more fiber and water. This makes them a suitable choice for those managing blood sugar, aiming for weight loss, or following a low-carb diet. These vegetables provide key vitamins, minerals, and antioxidants without excess calories, enabling larger portion sizes. The high fiber content in low-starch vegetables supports digestion and promotes fullness.
