Zucchini promoted as low‑calorie superfood for heart, gut and blood‑sugar health

Zucchini (Cucurbita pepo) contains about 17 calories per cup, with more than 90% water, making it a nutrient‑dense, low‑calorie food. It supplies notable amounts of vitamins A and C, magnesium, potassium and both soluble and insoluble dietary fiber, as well as antioxidants such as lutein and zeaxanthin.

The high fiber content supports digestive health by adding bulk to stool, speeding transit and feeding beneficial gut bacteria, which can lessen inflammation and symptoms of irritable bowel syndrome. Potassium and soluble fiber help lower blood pressure and reduce cholesterol absorption, contributing to cardiovascular protection. Its low glycemic index and minimal carbohydrate load make zucchini suitable for blood‑sugar regulation and weight‑management diets, especially for people with type‑2 diabetes or insulin resistance.
