Top 10 Benefits of Flavonoids

Flavonoids are a diverse group of phytonutrients found in almost all fruits and vegetables that are beneficial to your heart health. Flavonoids are the largest group of phytonutrients, with more than 6,000 types. They are potent disease fighters. Flavonoids act as a shield in plants to protect against toxins and to help repair the damage. It is assumed that when one eats flavonoids, they act quite similarly within one’s body. As antioxidants, they help prevent damage from free radicals that can build up during normal body processes. When flavonoids prevent free radicals from building up, as a result, cholesterol decreases. Flavonoid also helps to prevent clotting of the blood, lowers blood pressure, and lowers cholesterol, decreases inflammation and help with insulin sensitivity. Some of its health benefits are as follows:

8. Improves Cardiovascular functions

9. Supports the nervous system

Research shows that Flavonoids give protection to the nerve cells from oxygen-based damage. They also help during the demanding process of nerve regeneration. These are the benefits of flavonoid intake for the nervous system.
