目的:食品安全与否,关乎人们的健康乃至生命。随着对食品安全研究的深入,发现微量元素在食品 安全及营养中占有重要地位。微量元素必须通过饮食从外界摄入,食物中微量元素含量过低或过高都会影响人体 健康。如土壤污染会导致粮食微量元素含量过高,而一些地方水与食物微量元素含量不足,这些都会影响健康。 Purpose: food safety or not, related to people’s health and even life. With the deepening of food safety research, trace elements have been found to play an important role in food safety and nutrition. Trace elements must be taken from the outside world through diet, and trace amounts of trace elements in foods can affect human health if they are too low or too high. Such as soil pollution will lead to excessive levels of food trace elements, and some places less water and food trace elements, which will affect the health.
