laktasenzym

Laktasenzym is a Swedish term that translates to lactase enzyme. Lactase is a digestive enzyme produced in the small intestine of mammals, including humans. Its primary function is to break down lactose, a sugar found in milk and dairy products. Lactose is a disaccharide, meaning it is composed of two simpler sugar units, glucose and galactose. Lactase hydrolyzes the bond between these two units, separating them so they can be absorbed into the bloodstream.

The presence and activity of lactase are crucial for the proper digestion of dairy. In most infants, lactase production is high, enabling them to digest breast milk or formula, which are rich in lactose. However, in many human populations, lactase production declines significantly after infancy, a phenomenon known as lactase non-persistence or lactose intolerance. This decline is genetically determined and varies widely among different ethnic groups.

Individuals with lactase non-persistence may experience digestive discomfort, such as bloating, gas, diarrhea, and abdominal pain, after consuming foods containing lactose. This is because undigested lactose passes into the large intestine, where it is fermented by bacteria. The symptoms and their severity can vary depending on the individual's remaining lactase activity and the amount of lactose consumed.

In Sweden and other Nordic countries, the term laktasenzym is commonly used in discussions about lactose intolerance and digestive health. Products designed to aid lactose digestion, such as lactase enzyme supplements, are often referred to as containing "laktasenzym." These supplements can be taken before consuming dairy to help break down lactose and prevent or reduce the symptoms of intolerance.
