Do you know the important role of copper in maintaining human health? Do you know that copper deficiency in human body can lead to anemia, skeletal malformation, diseases of heart and circulatory system, nerves and immune system?
I believe most people don't understand this. People attach importance to iron supplementation because it plays an important role in preventing anemia, especially for women and children. People attach importance to zinc supplementation because zinc supplementation can improve people's immunity. In fact, few people understand the important role of copper in health, so they don't pay enough attention to copper. A study shows that more than half (56%) people think that copper has little or no important influence on health. In addition, many adults don't get enough copper. One reason is that foods containing fat and oil contain almost no copper. Eating processed convenience foods (such as fast food) without eating enough vegetables can easily lead to insufficient copper intake. Bao Shanfen, an associate researcher in the Trace Elements Research Office of China People's General Hospital, pointed out that although there is no obvious copper-deficient area in China, there are marginal copper-deficient people, including pregnant women, children and the elderly. Current research shows that copper deficiency will reduce human immunity, make people weak, lead to brain function damage and endanger health.
Copper: an essential nutrient for human body
Copper is an important component of protein and enzymes in the body and one of the special trace elements indispensable for human health. The results showed that at least 20 enzymes contained copper, among which at least 10 needed copper to function. The growth of babies, the strength of bones, the maturity of red blood cells and white blood cells, the operation of iron, the metabolism of cholesterol and glucose, the contraction of myocardium and the development of brain all need copper.
Copper is an essential part of human diet and plays an important role in many physiological processes, especially in the period of rapid growth and development. Copper is an essential nutrient during pregnancy. The fetus absorbs copper through the mother's placenta, which is necessary for the growth and development of the fetus in the uterus, especially in the first three months of fetal life. Pregnant women strive to ensure reasonable nutrition, because only a balanced nutrition can guarantee a daily intake of 2 mg of copper.
What are the consequences of the shortage of copper?
Health experts of the World Health Organization pointed out that the lack of copper is more harmful to health than the excess of copper, especially to children and the elderly. The common characteristic symptoms of copper deficiency are anemia, dysplasia, dysentery, hypothermia and pigmentation of skin and hair.
Clinically, most cases with obvious symptoms of copper deficiency are children, especially those who are underweight at birth. The most obvious symptoms of copper deficiency in infants are anemia (even iron supplementation will not help) and skeletal malformation (bone injuries such as osteoporosis are also common).
Breast milk is the best source of copper for newborns.
Which foods are rich in copper?
The World Health Organization recommends that the intake of copper be 2 mg per day.
Foods containing the most copper include seafood (especially aquatic crustaceans, such as oysters and crabs, which absorb a lot of copper in the process of foraging in the ocean), animal liver, coarse grains, nuts and vegetables (soybeans and lentils) and chocolate. Other foods containing copper include potatoes, peas, red meat, mushrooms, papaya and apples. Tea, rice and chicken contain less copper, but people can provide enough copper because of their high intake. In addition, natural water also contains copper, but it is worth noting that the pure water that people love to drink at present also filters out copper in natural water.
