Antioxidants function by neutralizing free radicals, which can cause oxidative stress and damage to cells, potentially leading to chronic diseases. These harmful compounds are produced through normal metabolic processes, environmental factors, and exposure to toxins. Antioxidant-rich foods, such as fruits, vegetables, and nuts, can bolster the body's defenses against oxidative stress, thus reducing the risk of diseases like cancer, diabetes, and cardiovascular conditions. Additionally, antioxidants may help promote healthy aging and improve overall wellness by supporting cellular health. Emphasizing a diet high in antioxidants is vital for maintaining long-term health.
