Given the question: I know that the answer to the question "Which group would exhibit more ability to eat unfermented milk-based foods, those with east Asian descent or northern European descent?" is in "Lactase is an enzyme that breaks down the disaccharide lactose to its component parts, glucose and galactose. Glucose and galactose can be absorbed by the small intestine. Approximately 65 percent of the adult population produce only small amounts of lactase and are unable to eat unfermented milk-based foods. This is commonly known as lactose intolerance. Lactose intolerance varies widely by ethnic heritage; more than 90 percent of peoples of east Asian descent are lactose intolerant, in contrast to about 5 percent of people of northern European descent.". Can you tell me what it is?
The answer is:
northern European descent
