Inorganic salts, also known as inorganic salts, are one of the seven essential nutrients for human tissues and maintaining normal physiological functions. It can be divided into macro elements and trace elements. The content in human body is more than 5g, and the daily demand for physiological activities is more than 100mg, which is called macro elements, such as calcium, phosphorus, potassium and sodium. Trace elements, such as iron, iodine, copper, etc., are extremely small and need more than 100 mg for daily physiological activities.
Minerals are an important part of human tissues. As we all know, calcium is an important component of human bones. If you lack calcium, it will lead to osteoporosis, backache and leg pain. Iron is the main component of hemoglobin. If the body lacks iron, it will lead to anemia and fatigue.
It can also regulate human body functions and help absorb energy. The metabolism of the body is inseparable from enzymes, which must be combined with minerals to produce activity. If the body lacks minerals, it will inevitably affect metabolism, and the direct impact on blood vessels is to cause metabolic waste to accumulate on the wall of blood vessels, thus triggering a series of cardiovascular and cerebrovascular diseases; Therefore, supplementing minerals needed by human body is beneficial to the prevention and treatment of cardiovascular and cerebrovascular diseases.
It is of great significance to prevent diseases, but due to physiological characteristics and social and environmental factors, middle-aged and elderly people are prone to vitamin deficiency and mineral deficiency.
After the age of 40, the body's immunity declines, organs begin to age, and various chronic and degenerative diseases gradually become entangled. Therapeutic drugs for some diseases will interfere with the absorption or utilization of vitamins or minerals and need additional supplements.
In order to solve the contradiction between supply and demand of vitamins and minerals, we should try to balance our diet. If the diet can't meet the requirements, you can also choose appropriate mineral supplements according to your personal situation. Objective: To improve the health status and quality of life of the elderly through nutritional intervention.
Minerals will be excreted through human metabolism, because they can't combine themselves in the body, so we need to supplement them with food and drinking water, but too much intake can easily lead to poisoning, and too little intake can cause many symptoms of the human body.
1) Potassium: The main function of potassium in human body is to maintain the balance of potassium and sodium and accelerate metabolism. Appropriate potassium supplementation is helpful to prevent and treat cardiovascular and cerebrovascular diseases such as hypertension. Onion, celery, eggplant, red dates, watermelons, hawthorn and other foods are rich in potassium.
2) Manganese: Manganese can maintain sugar metabolism and fat metabolism and improve the hematopoietic function of the body. Coarse grains such as barley, brown rice, peanuts, lettuce and vegetables are the main sources.
3) Calcium and magnesium: Xiao Nan talked a lot about calcium and magnesium, and reviewed the details himself. Foods to supplement calcium: milk, nuts, shrimp skin, sesame paste and other foods.
4) Iron: animal meat, blood, fish and shrimp; Fruits and vegetables are rich in iron elements such as auricularia auricula, spinach, kelp and cherry, which are easily absorbed by the human body.
A balanced diet is irreplaceable by dietary vitamins and mineral supplements. Please don't rely on dietary vitamins and mineral supplements to prevent chronic diseases. It is necessary to exercise regularly, eat more plant foods, limit alcohol intake, prohibit smoking, and properly supplement nutritional vitamins and mineral supplements to achieve the purpose of preventing diseases and prolonging life.
