Oxidants are reactive molecules that are produced both inside your body and the environment that can react with other cellular molecules in your body such as protein, DNA and lipids. When it does that, it damages molecules and it’s what causes disease and inflammation .
Are oxidants good for you?
Oxidation can damage vital molecules in our cells , including DNA and proteins, which are responsible for many body processes. Molecules such as DNA are needed for cells to function properly, so if too many are damaged, the cell can malfunction or die. This is why antioxidants are important.
Do we need oxidants?
To understand antioxidants, first we must understand oxidants — better known as free radicals. Free radicals are natural by-products our cells create when they convert food into energy. They’re a normal part of the way our bodies function, and natural oxidants are easily tolerated .
What would happen without antioxidants?
Without antioxidants, free radicals would cause serious harm very quickly, eventually resulting in death . However, free radicals also serve important functions that are essential for health ( 1 ). For example, your immune cells use free radicals to fight infections ( 2 ).
What foods are high in oxidants?

Why are oxidants bad?
When produced in excess, free radicals and oxidants generate a phenomenon called oxidative stress, a deleterious process that can seriously alter the cell membranes and other structures such as proteins, lipids, lipoproteins, and deoxyribonucleic acid (DNA) (5-10).
How are oxidants formed?
Oxidants are also generated by different types of radiation , with X-irradiation generating the hydroxyl radical and irradiation with ultraviolet light generating electronically excited states with subsequent radical formation. Ultrasound and microwave radiation can also generate reactive oxygen species.

What is the most powerful antioxidant supplement?
Vitamin E is the most powerful antioxidant of lipid membranes. Vitamin E is deposited, in a dose-dependent way, in cellular and subcellular membranes (mitochondria, microsomes), which are rich in fatty acids, and thus becomes an integral part of these structural elements, (Fig.
