Free radicals are unstable molecules that can cause damage to cells in our body. They are formed when atoms or molecules lose an electron, making them highly reactive. This can happen due to various factors, such as exposure to pollution, radiation, or even stress. When free radicals interact with other molecules, they can lead to a chain reaction, potentially harming important structures like DNA and proteins. To combat the effects of free radicals, our body relies on antioxidants, which are substances that can neutralize these harmful molecules. Antioxidants can be found in many foods, especially in fruits and vegetables. By consuming a diet rich in antioxidants, we can help protect our cells and maintain overall health.
