Q:Eat what food can add inorganic salt

Most of the food contains inorganic salts, the so-called inorganic salts, also known as minerals or ash. Minerals are naturally occurring compounds or natural elements in the crust. There are about 50 kinds of minerals in the human body, although they in the human body only 4% of body weight, but it is an essential part of the organism. According to their content in the body how much can be divided into constant elements and trace elements two categories. The body is actually composed of various elements (macro and trace). Many of these mineral elements are essential components of the enzyme, which can regulate a variety of physiological functions (such as maintaining osmotic pressure, oxygen transport, muscle contraction, nervous system integrity), but also tissue and bone growth and maintenance necessary. Some (such as calcium, phosphorus, sodium, magnesium, sulfur, chloride) content is large, while others are only trace. Human essential trace elements are cobalt (such as vitamin B12), copper, fluorine, iodine, iron, zinc, chromium, selenium, manganese, molybdenum In terms of its impact on experimental animals, nickel, tin and arsenic should also be considered necessary. Most minerals (except zinc) are widely distributed in a variety of foods and can be fully supplemented by balanced and diversified diets.

When it is completely absent, the plant can not complete its life cycle; The need for such elements is specific, other elements can not replace its role, the lack of plants will be a special lack of symptoms, only to meet this element, the symptoms will be eliminated; ⑧ this element must be in the plant from the body Direct effect, not just to improve the plant growth environment indirect role.
