In this modern days, children have more homework to do, more books to read, this gives their eyes more pressure to their eyes. But someone used to say that eyes are our windows, then how to protect eyes brightly and well is very difficult to many parents.
Zinc is the required nutrient for children during their growth and development. During children's growth, if they lack of zinc, it will cause dwarfism and dysplasia of intelligence. Because children is in high demand of zinc nutrition of faster growth and development. But unreasonable matching diet plan will cause inadequate zinc consumption.
Zinc can improve the optic nerve's sensitivity, when zinc nutrition ingestion is insufficient,cones in the retina photoreceptor pigment synthesis will be obstacle so as impact the distinguishment of color features. Zinc also has attribute of removing heavy metals such as lead and mercury.
Zinc largely found in animals meals, but if children eat too much meals, they could easily become fatter. Usually Chinese family eat vegetables more often. Vegetables contains rich oxalic acid, phytic acid, cellulose and other nutritions. They can severely interfere absorption of zinc.
My suggestion is children could should eat grapes and vegetables to supply zinc that they daily need.
