Lactose intolerance is one of the most important topics among authors magazines, portals and blogs about food. And although it would seem to have written anything new information is often found in many articles. So, let's separate the "wheat from the straw" and we shall understand the facts, that is lactose, lactose intolerance is manifested both in what products it contains.
What is lactose?
Simply put, lactose - a sugar of mammalian milk, including human breast milk. Scientists in the field of chemistry would say - this is a disaccharide composed of galactose and glucose molecules. Lactose is less sweet than sucrose or glucose is used in cooking. In addition to food destination, lactose is also used in the manufacture of drugs and pyrotechnics.
But back to the question of power. This disaccharide is cleaved in the small intestine by the enzyme lactase which separates it into simple sugars and ensures their absorption.
lactose intolerance
One of the most common digestive problem that occurs as a result of lactase deficiency. Lack of this enzyme leaves the excess sugar in the gut, which in turn, leads to the following: stomach bloating, gas, cramps and pain, nausea, diarrhea. Symptoms may vary in severity depending on lactose products or produce lactase deficiency.
Intolerance can be either congenital (rare form) and acquired. The second, in turn, is divided into:
● Primary - age lactase production decreases, causing the symptoms described above,
● Secondary is a consequence of the transferred diseases or surgical interventions.
At this stage also should explain the two terms are related to this division: alaktaziya when lactase from birth not produced and hypolactasia - the gradual loss of the enzyme for many years, despite the fact that before this problem is not occurred.
Which contains lactose?
Difficulties with digestion forcing people to give up foods containing lactose. This means that the diet is deprived of milk and a whole range of dairy products.
However, there are other foods that contain lactose. In addition to milk, a disaccharide found in many sweets, medicines, margarine, some types of bread (Toast, muffins), sauces, ice cream, butter, ready meals (pancakes, dumplings, croquettes) and soups fast cooking. Carbohydrates are also found in some meat products (pate, sausages, processed meat).
lactose-free diet
Fortunately, in most cases completely abandon food containing lactose, it is not necessary. Menu depend on the type of disease and the body's response to undigested sugar. In practice - it is an individual matter. Anyone who is faced with this disease, should know your own level of tolerance to lactose in a single meal, which is described below ailments do not arise.
Diet lactose-free does not necessarily mean a complete rejection of lactose products, only more precise control over food intake. Eliminating the menu a few ingredients and replacing them with lactose-free is a challenge that many cope successfully. But producers "milk" is increasingly produced on market products, which are already excluded this carbohydrate.
In addition, there are special so-called packaged diet for people with lactose intolerance, which is limited to amounts of dairy products, but the body is still fed daily dose of calcium, magnesium, potassium, zinc and vitamins Group B.
