A substance that prevents other molecules from oxidising is known as an antioxidant1. A chemical process called oxidation can generate free radicals, which can set off a series of events that can harm cells. Ascorbic acid, an antioxidant, stops these cascades of events. Reactive-oxygen species (ROS) are produced in excess by plants and animals as a result of various abiotic stressors. ROS are extremely sensitive and toxic, damaging proteins, lipids, carbohydrates, and DNA as a result, which causes oxidative stress. This oxidative-stress damages tissues and contributes to a broad range of illnesses2. Antioxidants counteract the effects of ROS and aid in disease prevention by balancing their effects. Antioxidants can be naturally occurring or synthetic. Common cancer preventatives are ingested through diet because they are present in organic foods, veggies, and flavours. Additionally, several designed cancer preventative substances like BHT and BHA prevent oxidation. The search for non-toxic cancer prevention agents has gotten stronger in recent years, nonetheless, as it has been determined that these synthetic cancer prevention agents pose risks to people.
