An example would be lactose intolerance, which is due to a deficiency of the intestinal enzymes that is essential for metabolism of the lactose in milk. Milk and dairy products contain lactose, a milk sugar.
Many people lack the intestinal enzyme, β -galactosidase (also called lactase), which breaks down the lactose molecule. When this enzyme is missing, lactose remains intact as it travels through the intestine.
Another example of most common metabolic food disorders is favism. Favism is caused by a deficiency of the enzyme glucose-6-phoisphate dehydrogenase in erythrocytes, which results in hemolytic anemia upon ingestion of fava beans, which contain several otherwise innocuous hemolytic agents.
