有些特殊地區,土壤中合有硒,其含量若超過百萬分之0.5,則所生長的作物即有毒性,對於牲畜危害性很大,牧民經濟損失頗巨,所以硒毒的問題才引起人注意。Moxon首先研究食物中營養素與硒毒的關係,發現高醣及高脂肪膳食抗硒毒的效力很弱,而高蛋白膳食的抗硒毒效力很強。Smith用含硒的小麥配成高低蛋白膳食兩種,也證明含 In some special areas, selenium is contained in the soil, and if the content exceeds 0.5 parts per million, the crops grown are toxic, harmful to livestock, and the economic losses of pastoralists are quite huge. Therefore, the problem of selenium poisoning only causes people note. Moxon first studied the relationship between nutrients in foods and selenium poisoning and found that the effect of high-sugar and high-fat diets on selenium poisoning is weak, whereas the high-protein diet has very strong anti-selenium toxicity. Smith with selenium wheat dubbed both high and low protein diet, also proved to contain
