Antioxidants are almost like celebrities: everyone knows them or at least has heard of them. We find them in everyday life, we can ingest antioxidants through our food, and they are also used in skin care products. But, honestly: if somebody would ask you to explain why they are so good and what function they fulfill - could you?
For my part, I love learning about all the things that can impact my life. Do you feel the same? Then let me take you on a little journey through the world of antioxidants and free radicals. Because without free radicals, antioxidants would not be what we value them for: the protectors of our body’s cells.
Free Radicals
So let's start by looking at free radicals. Free radicals are formed in the body. The cause of their formation can be external (exogenous) factors but also internal (endogenous) processes. For example, free radicals are part of the natural metabolism in the body. They form when the body uses oxygen to produce energy. They also fulfill essential tasks within the immune system, as they are used for chemical defense, such as against harmful viruses and bacteria.
However, "unbridled" free radicals can create a chain reaction in the body, which ends in cell and tissue damage. In technical jargon, this harmful process is called "oxidation." However, our body has various defense mechanisms to ensure that free radicals do not gain the upper hand and that everything remains balanced. These include some enzymes and also antioxidants.
Oxidative Stress
Cell damage occurs when the body is no longer able to keep free radicals under control. Then the relationship between defense mechanisms and free radicals is out of balance, and we speak of oxidative stress. This imbalance can occur when the body is exposed to negative habits and circumstances. These can fuel the formation of free radicals or weaken the body's defense against free radicals. Alcohol, smoking, physical and mental stress, lack of sleep, unbalanced diet, air pollution, too much sun, or inflammatory processes in the body are some prominent examples.
Oxidative stress today is associated with a variety of diseases. These include chronic inflammatory bowel disease, psoriasis, cataracts, and cancer. However, since some of the reasons for oxidative stress are due to our lifestyle, we can positively influence it. And we can help fight free radicals by regularly supplying the body from the inside and outside with antioxidants.
Antioxidants
Antioxidants can neutralize free radicals in the body. That is why they are also called radical scavengers. They are primarily supplied to the body through food and are contained in many foods. For example, blueberries, coffee, nuts, tomatoes, potatoes, and citrus fruits are considered excellent sources of antioxidants. Therefore, if you eat a balanced diet, you can actively support your body from the inside in the fight against oxidative cell damage.
