Atomic absorption spectrometry was used to test levels of serum Zn,Ca,Fe,Mg,Cu contents. 【Results】 The problems of eating behaviors in autism group were more than in the normal group. The rates of Zn, Fe or Ca deficiency were more serious in autism group than that in normal group. 【Conclusions】 The problems of eating behaviors and the deficiency of Zn, Fe or Ca among autisms is very serious.
