Overview

Trehalase deficiency is a metabolic condition in which the body is not able to convert trehalose, a disaccharide found in mushrooms, algae and insects, into glucose.[1][2][3] Individuals with this deficiency experience vomiting, abdominal discomfort and diarrhea after eating foods containing trehalose.[4][5] Studies suggest that this condition is very rare in white Americans, very frequent in Greenland natives (where it has been reported in 8% of the population), and not infrequent among Finns.[2][3][4][6] However, since ingestion of large quantities of foods containing trehalose in not common, the real frequency in unknown. Most cases appear to be inherited in an autosomal recessive manner.[2]
