Introduction
In general, fennel has certain auxiliary benefits for heart health, but its effects are limited, and it should be consumed in moderation. Fennel is rich in dietary fiber, vitamin C, and potassium. Potassium helps maintain normal heart rhythm and stable blood pressure, benefiting cardiovascular function; dietary fiber promotes intestinal motility and helps regulate blood lipid levels.
In general, fennel has certain auxiliary benefits for heart health, but its effects are limited, and it should be consumed in moderation. A detailed explanation is as follows:
Fennel contains abundant dietary fiber, vitamin C, potassium, and other nutrients. Potassium helps maintain normal heart rhythm and stable blood pressure, benefiting cardiovascular function; dietary fiber promotes intestinal motility and helps regulate blood lipid levels, indirectly reducing the burden on the heart; vitamin C, as an antioxidant, protects vascular endothelial cells and delays vascular aging.
However, as a seasoning or vegetable, fennel is typically consumed in limited quantities in daily diets, making it difficult to significantly improve heart health. Moreover, fennel is warm in nature, and excessive consumption may cause heat-related symptoms such as dry mouth and throat discomfort, which may negatively affect overall health. Therefore, intake should be controlled.
When consuming fennel, it can be combined with other vegetables and whole grains to enrich the dietary structure. During cooking, use minimal oil and salt, such as through cold mixing or stir-frying, to better preserve its nutrients.
