2. What are Antioxidants?
We partly covered this in the previous slide, so now you know that antioxidants act as scavengers in the body, helping to prevent and reverse cellular damage. There are two primary types of antioxidants, those created inside out bodies are called endogenous antioxidants and those obtained outside the body through diet are known as exogenous antioxidants. There are many exogenous substances out there that have antioxidant properties, but some of the most effective are thought to be vitamins A, C and E as well as beta-carotene and lycopene.
Vitamin C is the most abundant water-soluble antioxidant in the body while vitamin E is the most abundant fat-soluble antioxidant in the body. Together these substances (along with many others) help to defend against cellular damage caused by oxidation which can lead to serious and long-term health problems.
