What is the role of antioxidants in foods?

Antioxidants play a crucial role in food by counteracting free radicals, which are unstable molecules that can cause oxidative stress in the body. This oxidative stress is linked to various health issues, including inflammation, aging, and chronic diseases like cancer and cardiovascular problems. By neutralizing these free radicals, antioxidants help to protect cells from damage and support overall health.

In addition to their health benefits, antioxidants can also contribute to the stability and freshness of food by preventing oxidative degradation. However, the primary and most significant role of antioxidants in the context of food is their protective function against free radicals. This is particularly important in foods that are prone to spoilage and nutrient loss through oxidation.

The other options focus on different aspects of food properties. Enhancing flavors relates more to seasoning and spices, while acting as preservatives involves preventing microbial growth or spoilage rather than specifically targeting oxidative damage. Providing energy is crucial for macronutrients such as carbohydrates, proteins, and fats rather than the role of antioxidants.
