What are Free Radicals and How Do They Affect Your Health?

Free radicals are natural or man-made elements that can damage cells and DNA, leading to oxidative stress. These unstable molecules are produced by your body when turning food into energy, and can also be generated by exposure to environmental toxins like tobacco, alcohol, pollution, and ultraviolet rays from the sun or tanning beds. Additionally, substances found in processed foods can contribute to the formation of free radicals. The accumulation of free radicals in the body can lead to oxidative stress, which has been linked to various health conditions.

Oxidative stress caused by free radicals has been associated with the development of chronic diseases such as cancer, diabetes, and heart disease. The damage caused by free radicals can disrupt cellular processes and contribute to inflammation and tissue damage. Over time, this oxidative stress can contribute to the aging process and increase the risk of developing chronic conditions.

It’s important to note that while free radicals are naturally produced by the body and can have damaging effects, they also serve important functions in the immune system. The body has its own antioxidant defense system to neutralize and eliminate excess free radicals. However, when there is an imbalance between free radicals and antioxidants, oxidative stress can occur. This is why consuming antioxidants through a balanced diet is essential for protecting the body against the harmful effects of free radicals.

“The accumulation of free radicals in the body can lead to oxidative stress, which has been linked to various health conditions.”
