Antioxidants – why we can’t do without

A topic that is in the truest sense of the word brand new in these sunny months: free radicals and their antioxidants. Even without sunburn, UV radiation can create huge amounts of free radicals in the skin. In order to combat these extremely aggressive cell destroyers effectively, antioxidants from the inside and outside are required. If we would qualify free radicals exclusively as “bad”, that would be wrong. It is not for nothing that the body produces it itself during various metabolic processes. He needs them, for example, so that the immune system can keep bacteria, viruses or inflammatory press under control. Normally, the human body’s defense mechanisms are equipped to deal with a certain excess of free radicals. But our modern lifestyle is overwhelming. In addition to UV radiation, alcohol, smoking, the inhalation of environmental toxins and even blue light from smartphones, tablets and the like all promote the formation of these molecules that damage the cells. The body’s own defense system can no longer adequately eliminate the aggressors. Oxidative stress occurs. The cells become inoperable. Not only premature aging of the skin, but many health problems begin with it. Desperately looking for an electron If you want to understand the importance of antioxidants, you have to understand how free radicals work. The chemical structure of these oxygen-containing molecules is unstable because they lack an electron. In their search for a replacement they are extremely aggressive and extremely fast. It only takes 10-11 seconds (0.000 000 000 01 seconds) to find a suitable binding partner. They snatch the required electron from this intact molecule, which can be from the cell membrane, from a protein or from DNA. This electron robbery is known as oxidation. A chain reaction starts. The stolen molecule is now also a free radical and is looking for a victim. The higher the concentration of these killer molecules, the more massive the oxidative stress and the damage in the body. Depending on which molecules are affected, cell functions are impaired, and if the membrane is damaged, even cell death occurs. With DNA damage, uncontrolled cell division (development of cancer) is the result. And much more. The radical scavengers The power of antioxidants is that they make free radicals inactive and thus harmless. How? They add the missing electron to them. These radical scavengers are divided into five groups: vitamins, minerals, enzymes, trace elements and secondary plant substances (phytochemicals).… weiterlesen
