Antioxidantien im Körper: Schutzschild gegen schädliche freie Radikale

Antioxidants in the body: protective shield against harmful free radicals

Jul 31, 2023Robert Barabas-Steiner

Antioxidants are a fascinating group of nutrients that play a crucial role in maintaining our health. In this blog post, we will explain the importance of antioxidants in the body, what they are and how they protect us from harmful free radicals. Let's dive into the world of these vital molecules!

What are antioxidants?

Antioxidants are molecules that protect our body from oxidative stress by neutralizing free radicals. Free radicals are unstable molecules that are produced in the body due to natural metabolic processes or external factors such as pollution and UV radiation. Free radicals can attack cells and tissues by affecting their structure and function, which can lead to premature aging and various health problems.

The role of antioxidants in protection against free radicals

Antioxidants act as "radical scavengers" that neutralize free radicals by giving them an electron to stabilize them without becoming unstable themselves. This stops the harmful chain reaction of free radicals and protects cells and tissues from damage. It is important to understand that free radicals are not always harmful in themselves; in fact, they play a role in certain of the body's defense mechanisms. However, problems arise when the amount of free radicals in the body increases uncontrollably and the balance with antioxidants is disturbed.

Types of antioxidants

There are several types of antioxidants that work in our body, including:

01 Enzymatic antioxidants

These are produced by the body itself and include enzymes such as superoxide dismutase (SOD), catalase and glutathione peroxidase. They are highly specialized and work in specific areas of the cell to eliminate free radicals.

02 Non-enzymatic antioxidants

These antioxidants come from our diet and include vitamins such as vitamin C, vitamin E, beta-carotene (a precursor to vitamin A), and minerals such as selenium and zinc. Each of these antioxidants has specific functions and protects different parts of the cell from oxidative stress.

Antioxidants in the diet

A balanced diet plays a crucial role in providing our bodies with sufficient antioxidants. Colorful fruits and vegetables such as berries, oranges, broccoli and spinach are rich in vitamins and minerals that act as antioxidants. Nuts, seeds and vegetable oils, on the other hand, provide us with valuable non-enzymatic antioxidants such as vitamin E. Consuming these nutrient-rich foods helps protect our cells from free radical damage and promotes our health.


Antioxidants are our heroes in the fight against the damaging effects of free radicals. Their ability to neutralize oxidation processes and protect cells from damage is crucial for our health and well-being. By eating a balanced diet rich in antioxidant nutrients, we can actively contribute to building our inner protective shield against oxidative stress and thus lead a healthier life. Remember that it is important to eat a diverse range of foods to ensure that you get sufficient amounts of antioxidants and optimally support your health.
