What role do antioxidants play in the diet of older adults?

Antioxidants play a significant role in the diet of older adults by helping to protect cells from oxidative stress and reducing the risk of chronic diseases. As people age, their bodies often experience increased oxidative stress due to various factors, including environmental pollutants, poor diet, and metabolic processes. This oxidative stress can lead to cellular damage, contributing to the development of age-related diseases such as heart disease, diabetes, and certain cancers.

By ingesting foods rich in antioxidants—such as fruits, vegetables, nuts, and whole grains—older adults can neutralize free radicals, which are unstable molecules that cause oxidative damage. Increased antioxidant intake is associated with reduced inflammation, enhanced immune function, and a lower incidence of chronic diseases, making it particularly important for the aging population that may already be susceptible to these health issues.

In contrast, the other roles specified—such as increasing taste and flavor, aiding in digestion, or promoting muscle growth—are not directly related to the primary functions of antioxidants in the context of aging and chronic disease management.
