What is the main health risk of high levels of free radicals in the body?

High levels of free radicals in the body primarily lead to cellular damage. Free radicals are unstable molecules that can react with various cellular components, including DNA, proteins, and lipids. When these free radicals interact with cellular structures, they can cause oxidative stress, leading to the damage or degradation of these vital components. This oxidative damage is implicated in numerous diseases, including cancer, cardiovascular diseases, and neurodegenerative disorders.

Understanding the impact of free radicals on cellular function is essential since they contribute to the aging process and the progression of various chronic diseases. Maintaining a balance between free radicals and antioxidants can help protect cells from damage, highlighting the importance of antioxidants in the diet to mitigate the risks associated with elevated free radicals.
