Free radicals are molecules produced in the human body every day due to biological reactions that occur in cells.
They have free or unpaired electrons, so they are highly reactive. They tend to trap electrons from stable molecules to achieve their own electrochemical stability. Once the free radical manages to subtract the required electrons, the stable molecule provided to it becomes a free radical because it leaves unpaired electrons, which starts a real chain reaction and ends up destroying our cells.
These molecules are necessary to carry out certain functions and maintain health. These reactions in the body are encompassed as “cellular respiration”, which are necessary for cellular life, but the production of free radicals over time has negative effects since they alter cell membranes and genetic material, DNA in the cell. Its biological life is barely a microsecond, but it has the ability to react with everything that is around it causing damage to molecules, cell membranes and tissues.
These are responsible for neutralizing the oxidation of free radicals by releasing electrons captured by them in the blood. When our body has to tolerate an excess of free radicals for several years, organisms that are problematic for health appear.
Eating hydrogenated vegetable oils like margarine and trans acids in meat, milk fat, all of these contribute to the increase in free radicals. Antioxidants protect us from their harmful action. Fortunately, they are found in various places, either in topical or food form. Natural antioxidants are found in vitamins.
Vitamin C that abounds in citrus fruits such as lemon, orange, mandarin, kiwis, peppers, among others.
Vitamin E is found in avocado, spinach, broccoli, papaya, olive oil, milk, walnuts, almonds, chia and sunflower seeds, and oily fish.
Flavonoids, we eat them in onions, broccoli, apples, grapes, green tea, cocoa, oranges and other citrus fruits, blueberries and plums to name a few.
Beta carotene, these are found in fruits and vegetables such as carrots, mangoes, melons and tomatoes.
If we follow this type of diet rich in these vitamins, it will not be necessary to ingest any nutritional supplement or vitamins in pills of any kind, only if the doctor prescribes it that way.
The practice of these measures is beneficial to our long-term health. Do not forget that in addition to the function that these antioxidants already have to neutralize the damage of free radicals, they are also perfect allies to combat aging.
