Fennel Health Benefits
The iron, phosphorous, calcium, magnesium, manganese, zinc, and vitamin K content present in fennel all contribute to building and maintaining bone structure and strength.
Phosphate and calcium are both important in bone structure
Iron and zinc are crucial for the production and maturation of collagen
Bone matrix formation requires the mineral manganese
Vitamin K is important for health, as it modifies of bone matrix proteins, improves calcium absorption, and may reduce the excretion of calcium in urine.
In addition, there is evidence that potassium, calcium, and magnesium decrease blood pressure naturally. All of these are present in fennel. Dietary nitrates present in fennel and other foods have vasodilatory and vasoprotective properties. Because of this, they helps to lower blood pressure and protect the heart.
Fennel contains significant amounts of fiber. As fiber helps lower the total amount of cholesterol in the blood, it decreases the risk of heart disease.
The selenium found in fennel appears to stimulate production of killer T-cells. This suggests that it can improve the immune response to infection.
