The nutritional components of pollen are not only comprehensive, but also very high. The total content of protein is 7 ~ 10 times that of beef eggs. Iron is 20 times higher than spinach; Prototype carotene is 20 to 30 times more than carrot. The proportion of nutrients in pine pollen is reasonable, which is the same as that needed by human body. For example, there are eight kinds of essential amino acids that the human body cannot synthesize, some of which need more and some need less. The World Health Organization (WHO) and the Food and Agriculture Organization (FAO) have stipulated the required content and set the standard ratio, but it is still a mystery whether the content of pine pollen is consistent with their regulations. Moreover, it is a free amino acid, which is more easily absorbed by the human body. Therefore, the nutritional value is high.
