Elderly friends pay attention to copper
Copper is an indispensable trace element in the human body and plays a very important role in maintaining the normal physiological functions of the human body.
In the elderly, due to the digestive function of the kidney, the absorption function is reduced, and the absorption of copper in the substitute food is lowered. In addition, the replacement of the elderly teeth, chewing on the food, affecting the absorption of copper, and thus copper deficiency is prone to occur.
When the body is deficient in copper, the pigment oxidase in the brain cells is reduced, and the vitality is decreased, thereby causing memory loss, confusion, unresponsiveness, gait instability, and movement disorders.
In addition, the production of elastin and collagen in the cardiovascular system depends on the catalysis and activation of copper ions. If the body is chronically deficient in copper, it will cause arteriosclerosis and lead to coronary heart disease.
Clinical studies have found that patients with iron deficiency anemia should be able to think about the possibility of copper deficiency if they are not treated well with iron.
Cancer medical research has not found that copper has a role in anti-aging, protection of skin and hair, infection with influenza and cancer.
To prevent copper deficiency in the elderly, the key is to add more copper-rich foods such as shrimp, oysters, sea bream, fish, egg yolk, liver, tomatoes, beans and nuts.
The food should be chewed to facilitate the absorption of copper, not to eat or eat less refined food.
At the same time, do not take vitamin C immediately after meals, because vitamin C will prevent the absorption of copper.
