Zucchini — 17 kcal

Cooking can lower heat-sensitive vitamins like vitamin C, but it also increases the bioavailability of other nutrients such as lycopene and beta-carotene. Steaming or microwaving Zucchini preserves the most nutrients. The calorie count (17 kcal/100g) stays essentially the same.

Zucchini provides 1g of dietary fiber per 100g. Fiber supports digestive health, helps regulate blood sugar, and contributes to a feeling of fullness — all for just 17 kcal per 100g.

Vegetables like Zucchini contain a range of antioxidants including polyphenols, carotenoids, and flavonoids. These compounds help protect cells from oxidative stress. The specific antioxidant profile depends on the color and variety of the vegetable.

Both raw and cooked Zucchini have benefits. Raw preserves vitamin C and certain enzymes, while cooking breaks down cell walls and can increase mineral absorption. For the best of both worlds, try eating Zucchini in a variety of preparations.

Store Zucchini in the refrigerator crisper drawer, unwashed, in a loosely sealed bag to maintain humidity without trapping excess moisture. Most vegetables stay fresh for 5–7 days this way. Avoid cutting until you are ready to use it, as cut surfaces lose nutrients faster.
