Antioxidants contribute to healthy aging by neutralizing free radicals, which can cause cellular damage and accelerate the aging process. By reducing oxidative stress, antioxidants support the maintenance of cellular function and can lower the risk of age-related diseases such as Alzheimer's and heart disease. Foods rich in antioxidants include fruits, vegetables, nuts, and whole grains. Incorporating these foods into the diet can help improve overall health and longevity, enhancing the body's ability to combat the effects of aging. This dietary approach promotes a proactive stance toward maintaining vitality as one ages.
