Vitamins, also known as vitamins, are an essential class of organic substances that are essential for the maintenance of human life. They are also important active substances for maintaining human health. Vitamins are rarely found in the body, but they play an important role in human growth, metabolism, and development.
Vitamin A
The main effects (physiological functions) of vitamin A include: maintaining vision; promoting growth and development; maintaining the integrity and integrity of the epithelial structure; enhancing immunity; scavenging free radicals.
Food sources: First, the original vitamin A, that is, various carotene, is found in plant foods such as green leafy vegetables, yellow vegetables, and fruits. The richer contents include spinach, wolfberry, pea sprouts, sweet potato, Carrots, green peppers, squash, etc.; the other is vitamin A from animal foods, this type of vitamin A can be directly used by the body, mainly in animal liver, milk and dairy products and eggs.
Deficiency: Night blindness.
Vitamin B1
Function (physiological function): Promote growth; Help digestion, especially digestion of carbohydrates; Improve mental condition; Maintain normal nerve tissue, muscles, and heart activity; Reduce airsickness, seasickness; May relieve pain after dental surgery; Sleep at night Before taking 1 to 2 tablets, the mosquito repellent helps to treat herpes zoster.
Food sources: Yeast, rice bran, whole wheat, oats, peanuts, pork, most kinds of vegetables, wheat bran, milk.
Deficiency: Vitamin B1 deficiency is often due to inadequate intake, which can easily lead to dry beriberi, wet beriberi, infantile beriberi and so on.
Vitamin B12
Role (physiological function): promote the development and maturation of red blood cells, so that the body's hematopoietic function in a normal state to prevent pernicious anemia and maintain the health of the nervous system; the presence of coenzyme can increase the utilization of folic acid, promote carbohydrates, fats and proteins Metabolism; has the function of activating Amino Acids and promotes the biosynthesis of nucleic acids, which can promote the synthesis of proteins; metabolize fatty acids, make fats, carbohydrates, and proteins be properly used by the body; eliminate irritability, concentrate, enhance memory and balance; It is an indispensable vitamin for the function of the nervous system and is involved in the formation of a lipoprotein in nervous tissues.
Food sources: Animal liver, kidney, beef, pork, chicken, fish, mussels, eggs, milk, cheese, dairy products.
Deficiency: Pernicious anemia (red blood cell insufficiency); Irregular menstruation; Yellowing of eyes and skin, Local (very small) redness (no pain or itchiness) on skin, Accompanied by molting; Nausea, loss of appetite, weight loss; Lips, tongue, and Gingival pale, bleeding gums; headache, memory loss, dementia; may cause mental depression; cause meganucleolytic anemia (pernicious anemia); degeneration of the spinal cord, degeneration of nerves and peripheral nerves; mucosa of the tongue, mouth, digestive tract inflammation.
Vitamin B2
Role (physiological function): Participate in the metabolism of carbohydrates, proteins, nucleic acids and fats to increase the utilization of proteins in the body, promote growth and development; Involved in the growth and metabolism of cells is an essential nutrient for body tissue metabolism and repair; To strengthen liver function, Regulates the secretion of epinephrine; protects the function of the skin's hair follicle mucosa and sebaceous glands; interacts with other substances to help metabolize carbohydrates, fats, and proteins.
Food sources: milk and its products, animal liver and kidney, egg yolk, salmon, carrots, brewing yeast, mushrooms, seaweed, fish, celery, oranges, oranges, oranges and so on.
Deficiency: riboflavin deficiency; seborrheic dermatitis (eyes, nose and surrounding skin with seborrheic and dander and hard palate); causing red lips, stomatitis, cheilitis, angular cheilitis, glossitis; vaginal itching Oral ulcers and so on.
Vitamin C
Function (physiological function): promotes the biosynthesis of collagen, facilitates faster healing of tissue wounds; promotes the metabolism of tyrosine and tryptophan in amino acids, prolongs the life of the body; improves the utilization of iron, calcium, and folic acid; improves fat And lipids, especially the metabolism of cholesterol, to prevent cardiovascular disease; promote the growth of teeth and bones, prevent gum bleeding; enhance the body's anti-stress and immunity to the external environment.
Food sources: citrus fruits, vegetables and so on.
Deficiency: Scurvy; Gingival atrophy, bleeding; Arteriosclerosis; Anemia;
Vitamin D
Role (physiological function): Improve the body's absorption of calcium and phosphorus, make plasma calcium and plasma phosphorus levels reach saturation; promote growth and bone calcification, promote dental integrity; increase phosphorus absorption through the intestinal wall, and increase through the renal tubules Phosphorus reabsorption; maintain normal levels of citrate in the blood; prevent loss of amino acids through the kidneys.
Food sources: cod liver oil; butter; milk; dry grinding; dried fish; beef liver; chickens and so on.
Deficiency: rickets, severe tooth decay, osteomalacia, and osteoporosis.
Vitamin E
Function (physiological function): delay the aging of cells due to oxidation, maintain youthful posture; supply oxygen in the body to make you more durable; work with vitamin A to resist air pollution, protect the lungs; prevent blood clotting; reduce fatigue; Topical traumatic topical drugs (which can be absorbed through the skin) and internal medicines can prevent scarring; accelerate healing of the burns; use diuretics to lower blood pressure; prevent miscarriage; and help reduce leg cramps and hands and feet Stiff condition; reduces the chance of suffering from ischemic heart disease.
Food sources: Kiwi, nuts (including almonds, hazelnuts and walnuts), lean meats, milk, eggs, sunflower seeds, sesame seeds, corn, olives, peanuts, camellia and other vegetable oils. Including safflower, soybean, cottonseed and wheat germ (the most abundant one), spinach and kale, sweet potato and yam. Green leafy vegetables such as lettuce, day lily, cabbage, and cauliflower are vegetables that contain more vitamin E. Cod liver oil also contains certain vitamin E.
Deficiency: Red blood cells are destroyed, muscle degeneration, anemia, reproductive dysfunction.
Vitamin K
Role (physiological function): Vitamin K controls blood clotting; vitamin K is an essential substance for the synthesis of four coagulation proteins (prothrombin, transformation acceleration factor, antihemophilic factor, and Situ factor) in the liver; lack of vitamin K It will delay blood coagulation; it will cause neonatal bleeding and will not poison even if it supplies a lot of natural forms of vitamin K1 and vitamin K2.
Food sources: beef liver, cod liver oil, egg yolk, cheese, yogurt, yogurt, seaweed, alfalfa, spinach, cabbage, lettuce, broccoli, peas, parsley, soybean oil, spirulina, alfalfa.
Deficiency: neonatal hemorrhagic disease, such as hematemesis, bowel, umbilical cord, and prepuce hemorrhage; adult abnormal coagulation, leading to bleeding gums, nosebleeds, hematuria, stomach bleeding, and stasis; hypothrombinemia, symptoms of blood Prolonged clotting time, subcutaneous hemorrhage; children with chronic enteritis; tropical diarrhea.
Amino Acids
Amino acids are organic compounds containing basic amino groups and acidic carboxyl groups. The chemical formula is RCHNH2COOH. A compound formed by replacing the hydrogen atom on the carbon atom of a carboxylic acid with an amino group.Amino acids are the basic substances that constitute protein required for animal nutrition.Amino acids can play the following roles through metabolism in the human body: â‘ synthesize tissue protein; â‘¡turn into acids, hormones, antibodies, creatine and other ammonia-containing substances; â‘¢turn into carbohydrates and fats; â‘£oxidize into carbon dioxide, water and urea, generate energy.
