What are antioxidants and how do they support immune health?
Antioxidants are substances that can prevent or slow damage to cells caused by free radicals, unstable molecules that the body produces as a reaction to environmental and other pressures. They are believed to help boost the immune system, protect against free radicals, and reduce the risk of chronic diseases. By neutralizing harmful free radicals in the body, antioxidants help to maintain the health of the immune system and protect against harmful infections and diseases.
What types of antioxidants contribute to immune health?
Various types of antioxidants contribute to immune health. Vitamins C and E are potent antioxidants that enhance the immune function. Beta-carotene, a precursor of vitamin A, has antioxidant properties that boost the immune system. Trace minerals such as selenium and zinc also function as antioxidants and are essential for immune health. Phytochemicals, found in fruits and vegetables, are also potent antioxidants that support immune health.
How can one increase their antioxidant intake?
Increasing the intake of foods rich in antioxidants is the best way to increase your antioxidant intake. Fruits and vegetables are the richest sources of antioxidants. Other foods such as nuts, seeds, seafood, red meat, poultry, and grains also contain antioxidants. Another way to increase your antioxidant intake is through dietary supplements, but these should be used as a complement to a healthy diet, not a substitute.
What is the link between antioxidants and chronic diseases?
Research has shown a link between antioxidants and a reduced risk for chronic diseases like heart disease, cancer, and Alzheimer’s. The oxidative stress caused by free radicals can lead to cell damage and dysfunction, contributing to these diseases. By neutralizing free radicals, antioxidants can help protect cells from this damage and potentially prevent or slow the development of these diseases.
Can antioxidants help in preventing infections?
Yes, antioxidants can help in preventing infections. By strengthening the immune system, antioxidants help the body to fight off and resist infections. They do this by protecting immune cells from damage by free radicals and promoting the health and activity of these cells. In this way, antioxidants help to maintain the body’s natural defenses against infections.
