Method.
Background technique
Microelement plays an important role in human body and the growth and development process of animals and plants, but due to China region
The difference of the level of economic development, the factors such as living habit and food processing mode finally frequently can lead to the " nutrition of part population
It is bad ", that is, lack micronutrient, referred to as " recessive hunger ".
Tri- kinds of microelements of Fe, Zn, Se and human health have substantial connection.Fe is one of the essential trace elements of the human body,
There are about 4~5g Fe in adult body, wherein 72% with hemoglobin, 35% with myoglobins, 0.2% with other compound forms
In the presence of remaining is deposit Fe.Deposit Fe accounts for about 25%, is mainly stored in liver, spleen and marrow in the form of Fe albumen.Fe is in people
There is many-sided function in body metabolic process, synthesizes hemoglobin, participate in the transport and storage of oxygen, the conjunction of participant's hormone in vivo
At Fe can also promote to develop, and enhance body immunity, and adjusting tissue respiration prevents fatigue.Fe shortage can seriously endanger human body
Health, Fe deficiency disease and scarce Fe anaemia have become global health problem, and patients ' life quality is caused to deteriorate.Children Fe lacks
It will cause height and body weight increase be slow, can also damage the cognitive ability of children, and be also difficult to restore after supplementing Fe afterwards.
Zn is also one of the essential trace elements of the human body, is about 2.0g~2.5g in adult in-vivo content, is mainly gathered in
The internal organ of human body, muscle, blood, in bone, a series of physiological metabolisms in Zn participant's body, to growth and development, immune function, object
Matter metabolism and reproductive function etc. play an important role.Children and adolescents are in growth and development stage, if lacking Zn will lead to development not
It is good to result even in " nanism " and intellectual development is bad.It is tired to will lead to pachylosis, loss of appetite, spirit by scarce Zn in adult body
Sensory nerve variation of idle, adolescents in male hypogonadism, cell-mediated immune dysfunction and exception etc..
Se is one of micronutrient element needed by human, and Se total amount is dispersed throughout human body each group in 3~20mg in adult body
It knits in organ and body fluid, although content in vivo is very low, Se plays important and unique effect, because it is unique one
Kind introduces protein by the factor of genetic coding, as the 21st amino acids Se for the component part of cysteine, so far
25 kinds of Se albumen are identified in human protein's group.It is now recognized that organic Se just has biological function, have anti-
