The human metabolism consists of many complex biochemical reactions, most of which require the participation of enzymes. An important function of micronutrients is to make up the coenzyme components of various enzymes in the body, and also to act as activators of enzymes, thus regulating the physiological functions of the human body. If specific enzymes are deficient, the biochemical reactions of the body’s metabolism will not be carried out properly and the body will suffer from certain diseases as a result. The vast majority of people are currently in a state of micronutrient deficiency, which can lead to a variety of minor body problems. The following small body signals show that your body may lack certain micronutrients. 1, fatigue, drowsiness, weakness, difficulty concentrating, anemia – may be a lack of iron The largest function of iron is to transport oxygen from the lungs to various organs of the body in the form of hemoglobin, if iron deficiency will lead to a certain degree of oxygen deficiency in the brain and various organs of the body, so the body will appear drowsy, weakness and other phenomena. Iron deficiency anemia is a direct consequence of iron deficiency. Foods rich in iron are recommended: pork, beef, mutton, animal liver, animal blood, egg yolk, nori, kelp, black fungus, beans, etc. Among them, vitamin C helps the absorption of iron, but tannic acid in tea, oxalic acid in spinach, etc. will hinder the absorption of iron. 2, premenstrual tension, loss of appetite, decreased immunity, poor growth and development of children – may be a lack of zinc Zinc is a component of more than 100 enzymes in the body, these enzymes play an important role in the metabolism of proteins, fats, sugars, nucleic acids and so on. Foods rich in zinc are recommended: oysters, clams, mussels, lean meat, fish, animal liver and kidney, egg yolk, beans, nuts, mixed grains, etc. 3, muscle cramps, insomnia – may be a lack of magnesium The human body has about half of the magnesium stored in the bones, magnesium for maintaining bone health is essential. At the same time, magnesium ion has a sedative effect, so the magnesium deficiency of friends may have sleep-related health problems. Magnesium-rich food recommended: coarse grains, vegetables, mushrooms, nuts and fruits. 4, cramps, weakness, back pain, head sweating, sleep disturbance, bad teeth – may be a lack of calcium Calcium and human bone development is closely related, 99% of the calcium in the human body are distributed in the bones and teeth. Also, calcium plays an important role in blood clotting and in maintaining normal heart and blood vessel health. Vitamin D can promote the absorption of calcium, and sunlight can promote the secretion of vitamin D. Therefore, people with calcium deficiency should get more sunlight. Foods rich in calcium are recommended: various kinds of milk, various kinds of meat, beans, soy products, shrimp, kelp, seaweed, sesame paste, green vegetables, celery, broccoli, etc. 5, cold hands and feet, low immunity, vision loss – may be a lack of selenium Selenium can regulate thyroid function, control the body’s metabolism and blood circulation, therefore, zinc deficiency will lead to poor blood circulation, feeling cold hands and feet. Foods rich in selenium: oysters, shells, shrimp, snails, fish, sesame, malt, yeast, etc. 6, numbness in the hands and feet, weakness, weakened heartbeat, headache – may be a lack of potassium The loss of potassium in the body of people who taste heavier, often sweat, often smoke and drink will be more serious. Potassium affects nerve conduction, so potassium deficiency can make people feel numbness and weakness in their hands and feet, and can seriously affect heart health. Foods rich in selenium: fresh yellow-green vegetables and fruits and a variety of legumes. 7, dry and rough skin, increased age spots, vision loss, night blindness, low immunity, recurrent respiratory infections in children – may be a lack of vitamin A The main role of vitamin A is involved in cell differentiation and regulation of photoreceptors, so many skin diseases and eye-related diseases are related to vitamin A. Foods rich in vitamin A: animal liver, eggs and dairy products, red and orange vegetables and fruits, such as carrots, tomatoes, etc. 8, mouth ulcers, red and swollen gums, dry eyes, congested eyes, foot odor, bad breath, lusterless hair, easy to nervous – may be a lack of vitamin B B2 of the B vitamins is the most likely to be deficient, vitamin B2 is associated with almost all diseases related to the skin mucosa. The metabolism of alcohol can aggravate the loss of vitamin B2, so people who drink for years will often be accompanied by health problems such as mouth ulcers. Foods rich in vitamin B2: animal offal, dairy products, eel, crab, mushrooms, seaweed, seaweed, tomatoes, etc. 9, gum bleeding, loose teeth, frequent bruising, long wound healing time, urinary tract infection – may be a lack of vitamin C Vitamin C deficiency is mostly associated with “blood” disease, so vitamin C called ascorbic acid. It is also very important for collagen synthesis, skin strength and wound healing. Vitamin C-rich foods: most of the fresh vegetables and fruits, such as kiwi, strawberries, apples, oranges, dates, tomatoes, peppers, kale, cucumbers, cauliflower, cabbage, radishes, peas, etc. 10, diarrhea, no appetite, weakness, impatience, irritability, fetal malformation – may be a lack of folic acid Since folic acid is very important for the formation of the neural tube of the fetus, pregnant women should consume or supplement an adequate amount of folic acid before or during early pregnancy. Foods rich in folic acid: fresh fruits and vegetables, animal liver, legumes, nuts, cereals, etc.
