A genetic trait: why nearly half of Russians have difficulty digesting milk
A recent study has shown that about 46% of Russian residents have a genetic predisposition to lactose intolerance. This condition is linked to the way the body functions, where the enzyme lactase is not produced in sufficient quantities. It is this specific enzyme that is necessary for the proper breakdown of milk sugar.
However, experts urge people not to panic over this figure. Having a genetic predisposition does not at all mean that a person will necessarily feel unwell after consuming dairy products. Many people with this trait do not experience any unpleasant symptoms and can comfortably drink milk or eat yogurt in moderate amounts.
Specialists explain this by noting that sensitivity to lactose varies in degree. For many people, the body adapts, or the amount of the enzyme remains sufficient to digest small portions of the product. Furthermore, symptoms of intolerance often depend not only on genetics but also on the state of the gut microbiota and overall diet.
Doctors emphasize: if you do not feel discomfort, bloating, or pain after a glass of milk, there is no reason to exclude dairy products from your diet. A diagnosis of "lactase deficiency" is made only based on a patient's complaints and specific medical tests, not simply on the results of a genetic analysis.
Thus, the information about 46% of Russians is merely data regarding a biological trait, not a widespread illness. For those who do notice unpleasant reactions after eating, medical professionals advise switching to lactose-free products or plant-based alternatives, which are now widely available in Russian stores.
