Zucchini hailed as heart‑healthy superfood for adults over 50

Italian immunologist and nutrition professor Mauro Minelli explains that the common zucchini (Cucurbita pepo), which is over 95 % water, can help protect cardiovascular health after the age of fifty. Its high potassium content acts as a natural vasodilator, counter‑acting sodium‑induced blood‑pressure spikes, while its antioxidants lutein and zeaxanthin help prevent LDL oxidation that leads to atherosclerosis. The vegetable’s soluble fiber (pectin) slows sugar absorption, supporting stable blood‑glucose levels and reducing the risk of insulin resistance and type‑2 diabetes, both risk factors for heart disease. Minelli recommends brief cooking methods—steaming, quick sautéing, or raw preparation—to preserve potassium and heat‑sensitive vitamins. Regular inclusion of zucchini in the diet is presented as an inexpensive, everyday measure to lower the risk of stroke, heart attack and chronic inflammation that accompany aging.
