Understanding Antioxidants and Their Role in Health
Antioxidants are essential compounds that protect the body from oxidative stress, a biological process that occurs when free radicals accumulate and cause cellular damage. Free radicals are unstable molecules that result from metabolic processes, environmental toxins, and inflammatory responses. When left unchecked, oxidative stress can contribute to premature aging, chronic inflammation, and the development of serious conditions such as cardiovascular disease, cancer, and neurodegenerative disorders. Understanding what antioxidants are and their importance is crucial for making informed dietary choices that support long-term health and disease prevention.
The human body naturally produces some antioxidants, but external sources from food are vital to maintaining an optimal balance. The most potent antioxidants include vitamins C and E, beta-carotene, flavonoids, polyphenols, selenium, and other phytonutrients found in plant-based foods. These compounds neutralize free radicals by donating electrons, preventing them from causing further damage to cells and tissues. A diet rich in antioxidant foods strengthens the body’s defenses and plays a key role in overall well-being.
