Antioxidants: Nutrition Facts and Health Perks
In the ongoing battle against chronic diseases, antioxidants have emerged as potential allies. These substances, found in various foods and supplements, help neutralise free radicals, waste substances produced by the body and environmental pressures, which can cause oxidative stress and damage cells and organs.
Free radicals, often by-products of metabolic processes, can increase the risk of inflammation and various health issues, including cardiovascular diseases, neurodegenerative diseases, diabetes, cancers, gastrointestinal diseases, inflammatory conditions, and even the aging process. For instance, oxidative stress contributes to atherosclerosis by oxidising LDL ("bad") cholesterol, triggering immune responses that lead to fatty deposits narrowing blood vessels, increasing the risk of heart attacks and strokes.
Antioxidants, on the other hand, protect DNA, lipids, and proteins from oxidative harm, helping maintain normal cell functioning and reducing tissue damage. They support the body's redox homeostasis—the balance between oxidants and antioxidants—which is critical for preventing oxidative stress-related damage and systemic inflammation. Enzymatic antioxidant systems in the body, such as superoxide dismutase and catalase, and dietary antioxidants, like vitamins C and E, vitamin A, beta-carotene, lycopene, selenium, manganese, and various phytonutrients, help maintain this balance and mitigate damage to cells and organs.
However, it's important to note that while antioxidants are beneficial, high doses of antioxidant supplements can be harmful, and caution is needed regarding supplements. For example, a high intake of beta-carotene may increase the risk of lung cancer in smokers, and a high dose of vitamin E has been found to increase the risk of prostate cancer.
The best sources of antioxidants are plant-based foods, especially fruits and vegetables. Including a fruit or a vegetable in every meal and snack, drinking green or matcha tea daily, and adding foods with rich colours to the diet can help increase antioxidant intake. Examples of antioxidant-rich foods include tomatoes, watermelon (for lycopene), green and black teas, red grapes, dark chocolate, pomegranates, goji berries, and a variety of fruits and vegetables such as carrots, peas, spinach, and mangoes.
For people at risk of age-related macular degeneration, it is essential to seek advice from a doctor about whether to use supplements and which ones to use. Consuming fruits and vegetables has been linked to a lower rate of chronic diseases, but it is unlikely that consuming added antioxidants, especially in processed foods, will provide significant benefits.
In conclusion, while antioxidants play a crucial role in defending against oxidative damage and lowering the risks of chronic diseases, it's important to maintain a balanced diet and consult a health provider before making significant changes to your supplement intake. Eating a variety of antioxidant-rich foods, both cooked and raw, is key to maintaining good health.
