West Indian cherry is recognized as "the king of natural vitamin C" and "the fruit of life" in the world. The content of vitamin C in 100g fresh acerola cherry is as high as 1500-2200mg, which is 3 1 times that of lemon, 27 times that of strawberry and 8 times that of kiwifruit. Compared with synthetic vitamin C, the natural vitamins in West Indian cherries are better absorbed and act in the body for a longer time.
West Indian cherry also contains vitamin A, vitamin B 1, vitamin B2, iron, calcium and other elements. Vitamin C is an indispensable ingredient to maintain human life, which can prevent colds and scurvy, improve human immunity, promote iron absorption, resist oxidation and promote collagen synthesis. Widely used in health care, beverages, beauty and other fields.
I believe everyone is familiar with vitamin C. We often hear that vitamin C can whiten skin, resist oxidation and delay aging.
In fact, the role of vitamin C is far more than you know. Bian Xiao will learn about vitamin C with you.
What is vitamin c?
The structure of vitamin C is similar to that of glucose, and it is a polyhydroxy compound. The second and third adjacent enol hydroxyl groups in its molecule are easy to dissociate and release H+, so it has the nature of acid, also known as ascorbic acid, and is an essential nutrient for human body. Most organisms can produce ascorbic acid through metabolism, but humans are the most notable exception. They need food to get ascorbic acid.
The most common understanding of vitamin C is that "lack of vitamin C can cause scurvy". In organisms, vitamin C is a coenzyme and an antioxidant, which can protect the body from free radicals.
Small VC, big effect
1, improve human immunity: white blood cells are rich in VC, and when people are infected, the VC in white blood cells decreases sharply. VC can enhance the chemotaxis and deformability of neutrophils and improve their bactericidal ability. Promote the generation of lymphocytes and improve the body's ability to identify and kill foreign cells and malignant cells. Participate in the synthesis of immunoglobulin. Improve the activity of complement esterase in CI and increase the production of complement CI. Promote the production of interferon, interfere with the transcription of virus mRNA, and inhibit the proliferation of virus. Improve human immunity and prevent colds.
2. Treatment of anemia: It can reduce trivalent iron that is difficult to be absorbed and utilized to ferrous iron, promote the absorption of iron in intestine, improve the utilization rate of iron in liver, and help to treat iron deficiency anemia.
3. Anti-scurvy: The strength of blood vessel wall has a great relationship with VC. Microvessel is the smallest of all blood vessels, and its wall may be only one cell thick, and its strength and elasticity are determined by collagen. When VC is insufficient in the body, microvessels are easy to rupture. Therefore, when vitamin C is deficient, congestion and cyanosis will appear on the skin surface; When it happens in the body, it can cause pain and joint swelling. In severe cases, bleeding of stomach, intestine, nose, kidney and periosteum may occur.
4. Collagen synthesis: The human body is composed of cells, which are connected by intercellular substance, and the key component of intercellular substance is collagen. Collagen accounts for 1/3 of the protein of the body, which generates connective tissue and constitutes the bones of the body. Such as bones, blood vessels and ligaments. Determine the elasticity of the skin, protect the brain and contribute to the healing of human wounds.
5. Gum atrophy and bleeding: A healthy gum tightly wraps every tooth. Gingiva is soft tissue, which is prone to atrophy and bleeding when lacking protein, calcium and VC.
6. Prevention of arteriosclerosis: It can promote the excretion of cholesterol and prevent cholesterol from depositing on the inner wall of arteries.
7, strong water-soluble antioxidants: can reduce and protect other antioxidants, such as vitamin A, vitamin E, unsaturated fatty acids, to prevent free radicals from harming the human body.
8, anti-cancer: rich collagen helps to prevent the spread of cancer cells; The antioxidant effect of VC can resist the damage of free radicals to cells and prevent cell variation; Prevent nitrite and secondary amine from forming strong carcinogen nitrosamine. Someone once dissected a patient who died of cancer and found that the VC content in the patient was almost zero.
9. Protect cells, detoxify and protect liver: In human life activities, it is very important to ensure the integrity of cells and the normal metabolism. Therefore, glutathione and enzymes play an important role. Glutathione is a short peptide composed of glutamic acid, cystine and glycine, which has redox effect in the body. It exists in two forms, namely oxidation type and reduction type, and reduction type plays an important role in ensuring the integrity of cell membrane.
10, improve the body's stress ability: abnormal stimuli, such as severe pain, cold, lack of oxygen and strong mental stimulation, will trigger a state of tension against abnormal stimuli. This state is accompanied by a series of organisms, including sympathetic nerve excitement, adrenal medulla and increased secretion of corticosteroids. Adrenaline and norepinephrine secreted by adrenal medulla are converted from tyrosine, which requires VC. Vitamin C entering the human body is rapidly distributed in 20 tissues and organs. Under normal circumstances, the human vitamin C bank is 1500 mg. Most of the excess is excreted with urine, and a small part is excreted with stool, sweat and respiratory tract. However, in the case of infection, the human body needs 20-40 times as much as usual, and all drugs will destroy VC in the body, so it is very beneficial to supplement VC when the human body is in a state.
