Essential micronutrient and toxic trace element concentrations in gluten containing and gluten-free foods

摘要: For individuals following a gluten-free (GF) diet, rice is commonly the major grain. People GF diet have higher arsenic burden than general population. We conducted multielemental market basket study of and gluten containing ingredients prepared foods (Mn, Fe, Ni, Cu, Zn, Cr, Co, Se, Cd, Sb, Pb, total As, As species, Hg methylmercury). Foods were significantly in Pb lower Cu Zn. Wheat-based Cd. Mercury concentrations low (<3.5 ng/g); speciation was predominantly methylmercury. Arsenic mercury correlated. contained more Hg. Eating wide variety grains may reduce contaminant exposure increase micronutrient status compared to rice-based diet.
