Free Radicals
- Free radicals are molecules that have lost one or more electrons. This causes the molecules to become unstable.
- In order to return to a stable state, they must immediately regain the electron(s) they have lost.
- Free radicals are constantly formed in the body—for example, when we breathe, exercise, eat, when the body eliminates harmful substances, when we smoke, and due to various forms of radiation.
- Free radicals damage our DNA, cell membranes, lipids, proteins, and cartilage/connective tissue.
Antioxidants
- Antioxidants are substances that neutralize free radicals.
- Antioxidants neutralize free radicals
- Antioxidants must “regenerate” themselves after neutralizing free radicals. Many antioxidants work in pairs so that they can help each other regenerate.
- The body produces antioxidants on its own. One very important antioxidant is called glutathione. It is produced in the liver. Other examples of antioxidants include vitamins A, B1, B6, C, and E, as well as coenzyme Q10.
Important sources of antioxidants:
- Spices
- Herbs
- Fruit
- Vegetables in general, and colorful vegetables in particular
- Nuts
- Blueberries, blackberries, and other dark berries
- Green tea
- Fruits and vegetables are rich in vitamins and minerals that keep us healthy.
- That is why it is recommended that we eat at least 500 grams of fruits and vegetables every day.
