In some cases, free radicals can also play certain physiological roles. For example, in the immune system, free radicals help the body eliminate pathogens. Additionally, some studies suggest that modest free radical production may help regulate cell signaling and metabolic pathways.
"Free radicals" are unstable compounds in the body. Just like a thief, your living habits (tobacco and alcohol), careless diet, and external factors (injury, infection, stress) can steal the electrons of healthy cells at any time, causing the cells to lose their normal functions and age and wither. Death. This reaction is called "oxidation reaction". Therefore, in general, too many free radicals are considered unfavorable.
The danger of free radicals that needs more attention is that they cause an "inflammatory reaction" in the body. When there are too many free radicals in the body, it will trigger a series of attacks, inflaming cells and even affecting every organ, causing diseases, such as: heart disease. Vascular disease, diabetes, cancer, etc.
As you get older and your body's antioxidants are insufficient to deal with oxidative reactions and extinguish inflammation (anti-inflammation), your body will begin to age, and you will find that your face begins to look older, and chronic diseases begin to appear on your body. Do you still remember why during the epidemic, the mortality rate of the elderly or those with chronic diseases after diagnosis was higher than that of the general population? Because these high-risk groups usually have to deal with too many free radicals in the body, coupled with the invasion of viruses, the body cannot resist the dual enemies and is defeated.
If you want your body to delay aging or face the attack of a virus,
Have sufficient resistance to meet the challenge,
Usually we should pay attention to the body’s high oxidation indicators!

Intracellular lipid oxidation marker MDA :
When free radicals attack the phospholipids on the cell membrane, lipid peroxidation is triggered and malondiadehyde ( MDA ) is produced. It binds to DNA and proteins to disrupt normal cell development, leading to disease. The higher the MDA , the worse the antioxidant capacity. It attacks the skin, causing wrinkles and spots, and aging the skin . It may also destroy cholesterol and damage blood vessels, leading to cardiovascular diseases such as arteriosclerosis . It may also damage the connections of DNA. Damage to the DNA structure increases the risk of cancer over time.
-
Nitrotyrosine :
It is an indicator of protein oxidative damage. When nitrotyrosine levels rise in the blood, it indicates that the body is suffering from oxidative stress. Exposing the body to chronic inflammation and oxidative stress increases the risk of cardiovascular disease, stroke, kidney failure, and other diseases.
-
CoQ10 :
CoQ10 is also a powerful antioxidant that helps protect cells from free radical damage. Because CoQ10 is involved in cellular energy production and anti-aging capabilities, it can delay cellular aging. If coenzyme Q10 is low, it means that the cells' ability to deliver oxygen and fight against free radicals is insufficient, and aging will accelerate.
To put it simply, when the antioxidant power in the body cannot keep up with the number of free radicals, the detoxification ability of the body will be weakened, and the body's appearance and internal organs will accelerate aging over time.
In addition, on weekdays, the body needs to be replenished with combat readiness supplies to enhance the body's combat effectiveness. "Antioxidants" are very important substances. Antioxidants can neutralize free radicals. After satisfying the desire of free radicals to steal things, free radicals will reduce the damage to normal cells. Consuming enough antioxidant foods or nutrients regularly can help balance free radicals and prevent oxidative stress.-
Glutathione:
It is the most powerful and efficient antioxidant in the body and is called the mother of antioxidants. Glutathione is mostly found in the liver and kidneys, providing antioxidant, detoxification, and hepatoprotective effects. Vitamins C and E, which are generally known to the public, also require sufficient glutathione to function properly.
Food: Asparagus, spinach, okra, avocado, or eating sulfur-containing compounds (broccoli, cabbage, onions, garlic) can also be converted into glutathione in the body and used by the body.
-
Selenium (Se):
When glutathione acts as an antioxidant (such as when the liver is detoxifying), it needs the help of selenium to effectively detoxify. In addition, selenium can also regulate immunity in the body and inhibit inflammation.
Food: Nuts (pumpkin seeds, Brazil nuts), shrimp, mushrooms, etc.
-
Vitamin C:
It can capture free radicals and act as a scavenger of O2 to terminate the chain reaction of free radicals and reduce oxidative damage. It can also work synergistically with vitamin E to scavenge free radicals and regenerate the reduction of vitamin E.
Food: Guava, berries (strawberries, blueberries), kiwi, red and yellow bell peppers, spinach, etc.
-
Vitamin E:
Fat-soluble antioxidants are distributed on cell membranes and can interrupt free radical lipid peroxidation.
Food: Nuts (cashew nuts, sesame seeds, walnuts, sunflower seeds), wheat germ, olive oil, etc.
-
Phytochemicals (β-carotene, lycopene, flavonoids, polyphenols):
Known as the vitamin of the 21st century. It has powerful antioxidant function to scavenge free radicals in the body, thereby reducing inflammation, effectively detoxifying, improving immunity, activating macrophages, and promoting apoptosis of cancer cells.
Food: red (tomatoes, red peppers, strawberries), orange (yellow peppers, carrots, corn), green (dark leafy vegetables), white (onions, garlic, white radish), purple (eggplant, purple cabbage, blueberry)
The body is your own. To fight against excessive free radicals in the body, long-term daily maintenance is definitely better than temporary care!
In addition, it is also reminded that when ingesting food, try to use prototype food as the main food!
