Trace elements in human body can be divided into essential trace elements and non-essential trace elements according to different physiological functions. Calcium, copper, magnesium, zinc and iron are all essential trace elements in human body, which constitute the components of cells in human body and participate in the synthesis, decomposition and transformation of substances in the form of coenzyme and auxiliary activator. Trace elements participate in the regulation of metabolism, the synthesis of enzymes, the composition of respiratory chain and the growth and development of immune system, and are indispensable elements for life activities and reproduction.
Vitamins are important to human health, but trace elements are also important. Because vitamins can be synthesized in the human body, but trace elements can't, they can only be obtained from plants, even trace elements obtained from animal foods are obtained from plants.
If plants lack trace elements, they will not only grow well, but also directly affect our human health. Fortunately, trace elements necessary for plants, except boron, are also necessary for human body. Therefore, as long as we are not picky about food and eat more vegetables, all the trace elements we generally need can be obtained from food. Iron needs to be replenished. Without iron, hemoglobin cannot be synthesized, leading to anemia. Therefore, eating more iron-rich laver, black fungus and mushrooms must be good for your health.
