Topic: Lactose Intolerance by Ethnicity and Region
Anonymous A started this discussion 10 years ago#57,095
An estimated 65% of human adults (and most adult mammals) downregulate [decrease] the production of intestinal lactase after weaning. Lactase is necessary for the digestion of lactose, the main carbohydrate in milk, and without it, milk consumption can lead to bloating, flatulence, cramps and nausea. Continued production of lactase throughout adult life (lactase persistence, LP) is a genetically determined trait and is found at moderate to high frequencies in Europeans and some African, Middle Eastern and Southern Asian populations.
