Not all athletes include cottage cheese and milk in their diet, especially if these foods cause certain unpleasant feelings in the gastrointestinal tract. This condition is called lactase insufficiency or intolerance of products containing lactose (lactose intolerance).
Let's take a moment and discuss what lactose is. Lactose, or milk sugar, is 4-(β-galactopyranosido - β-galactopyranosido) -glucose. It is contained in milk in the amount of 4-5% and can be obtained from the whey of curdled skimmed milk after separating the cottage cheese, evaporating and crystallizing. Lactose is 4-5 times less sweet than sucrose. When exposed to enzymes in the body, lactose is split into D-galactose and D-glucose. Some organs of plants and animals often contain special enzymes, called lactase (lactase), which break down the milk sugar. Humans aren’t among those animals lucky enough to have this.
In fact, milk and lactose-containing products were invented by nature for children, since the amount of the digestive enzyme in a child’s system is contained in a sufficient amount for digestion! Breast milk is the only adequate food for children, especially in the first 6 months.
Further, nature has developed all organisms in different ways: someone has been fortunate to eat cheeses all of their life, while someone else has to pass because of insufficient amounts of lactase. Such conditions can have an innate nature, called primary lactase insufficiency, and acquired, or secondary lactase deficiency.
The secondary type may occur in athletes due to eating disorders and possible problems with the gastrointestinal tract. That is the reason why many people do not use dairy products in their diets.
In order to protect yourself from issues of lactose within your body, make sure that you read product labels. Very often this milk sugar can be hidden under such names as artificial butter flavor, butter, caramel color or flavoring, casein or caseinate, cheese, cream, dried milk, high protein flour, lactalbumin, lacitol (E966), lactose, lactoferrin, lactoglobulin, milk derivatives or powder or solids, natural flavoring, non-fat milk solids, whey, whey protein and whey solids concentrate.
There are even special departments in supermarkets with lactose-free products, but the problem is that even those products can cause symptoms from the gastrointestinal tract. Lactose in such products is not removed. The enzyme "lactase" is added to the product additionally, which helps to digest milk sugar.
If you suffer from lactase deficiency (although for adults is is now the norm), use other high-protein foods in your diet.
