substances that help to prevent cell damage

Antioxidants are substances that help to prevent cell damage.

molecules which prevent oxidation

Antioxidants are molecules which prevent oxidation, a process that produces something called free radicals.

free radical scavengers

We previously proposed that extractives in highly durable heartwood may protect wood against fungal colonization and subsequent degradation by dual mechanisms: the extractives have some fungicidal activity and are also free radical scavengers (antioxidants).

nutrients that block some of the damage caused by free radicals

Antioxidants are nutrients that block some of the damage caused by free radicals.

substances that counter the effects of free radicals

Antioxidants are substances that counter the effects of free radicals.

nutrients

Antioxidants are nutrients (vitamins, minerals, carotenoids, polyphenols and other phyto-chemicals), as well as enzymes (proteins in the body that assist in chemical reactions).

substances that reduce damage caused by oxygen

Antioxidants are substances that reduce damage caused by oxygen.

man-made or natural substances that may prevent or delay some types of cell damage

Antioxidants are man-made or natural substances that may prevent or delay some types of cell damage.

molecules that help the body combat free radicals

Antioxidants are molecules that help the body combat free radicals.

compounds that help protect against free radical damage

Antioxidants are compounds that help protect against free radical damage.

substances that destroy free radicals, which are compounds in the body that damage cell membranes, tamper with DNA, and even cause cell death

Antioxidants are substances that destroy free radicals, which are compounds in the body that damage cell membranes, tamper with DNA, and even cause cell death.

chemicals that are responsible for preventing oxidation of cells

Antioxidants are chemicals that are responsible for preventing oxidation of cells.

vitamins, minerals, and nutrients that protect and repair cells

In a nut shell, antioxidants are vitamins, minerals, and nutrients that protect and repair cells fr0m damage caused by free radicals and oxidative stress.

substances that protect the body from oxidative stress

Antioxidants are substances that protect the body from oxidative stress.

nutritionally-based substances that act as free radical scavengers

Antioxidants are nutritionally-based substances that act as free radical scavengers.

Substances that have the ability to fight radicals

Substances that have the ability to fight radicals are called antioxidants.

components that prevent the free radicals from damaging our cells

Antioxidants are components that prevent the free radicals from damaging our cells.

substances that neutralize free radicals — unstable oxygen molecules that break down skin cells and cause wrinkles

Antioxidants are substances that neutralize free radicals -- unstable oxygen molecules that break down skin cells and cause wrinkles.

compounds that neutralize free radicals -- molecules that can damage body cells and contribute to disease

Antioxidants are compounds that neutralize free radicals -- molecules that can damage body cells and contribute to disease.

nutrients () vitamins and minerals

According to the Health section of How Stuff Works, “Antioxidants are nutrients (vitamins and minerals) and enzymes (proteins inside your body) that can help to prevent and repair damage to your body’s tissue.”
