If a person has lactase deficiency, drinking milk is contraindicated for him, – Elena Tikhomirova, a therapist and nutritionist, recalled in an interview.
Doctor Tikhomirova explained in an interview with Gazeta.ru that lactase is a pancreatic enzyme. Thanks to its production, the body normally absorbs milk. Lactase helps digestion break down lactose, the sugar found in milk.
“The enzyme lactase breaks down lactose into glucose and galactose, which are then absorbed into the intestines without any negative consequences for the body,” said the expert.
Tikhomirova said that far from all people, lactase is fully secreted by the pancreas throughout life –
“in some adults, the lactase enzyme may disappear over time, or its activity noticeably decreases.”
According to the physician, lactase deficiency, in which “milk” is not absorbed, is indicated by symptoms in the form of bloating, rumbling, gas formation, abdominal discomfort and other sensations characteristic of indigestion – they all occur after the acceleration of milk and products based on it. Experiencing these ailments, adults should not drink milk, otherwise the microflora of the digestive tract may suffer.
