Does the lactobacillus have lactose


Lactose intolerance

Lactose intolerance / lactose intolerance - what is that anyway?

Do you have complaints after consuming dairy products? This is often an indication of an existing lactose intolerance. If there is a deficiency or loss of activity of the enzyme lactase (enzyme that splits milk sugar, see also, the body is not able to break down the lactose properly.

But what is lactose? Lactose (= milk sugar) consists of a combination of two sugars (glucose and galactose). In order to be able to digest the lactose without any problems, we need the digestive enzyme lactase. If there is too little or no lactase in the small intestine, the lactose cannot be broken down and it reaches the large intestine unchanged. This leads to symptoms such as abdominal pain, diarrhea or flatulence. Intestinal diseases or a disturbed intestinal flora can also lead to lactose intolerance or a lactase deficit.

What are the symptoms

How do I know if I am lactose intolerant? In the case of lactose intolerance, the milk sugar reaches the large intestine unchanged. The symptoms vary from person to person. This depends on the one hand on the amount of lactose you consume and on the other hand on how much lactase the intestine still produces. Not all people are equally sensitive. The symptoms mainly affect the digestive tract and make themselves felt Flatulence, Failurel, stomach pain and orStomach cramps.Many sufferers also suffer from nausea andVomit right after a meal containing lactose.

What is helpful?

It is recommended to limit the consumption of foods containing lactose. If you don't want to do without dairy products entirely, you have the option of taking lactase supplements if necessary. These are taken directly before or with a meal and provide the body with the missing enzyme so that lactose can be broken down.

Probiotics and lactose intolerance

Most lactic acid bacteria naturally have the ability to metabolize lactose and fructose and support the digestion of these sugars. These support the uppermost intestinal cells to be able to produce more lactase themselves. [1] Thanks to the ß-galactosidase produced by lactic acid bacteria, it has been possible to improve the tolerance of lactose in people with lactose intolerance [2,3]. The bifidobacteria in particular have a positive effect [4]. Numerous studies have also shown that yogurt with viable bacteria (Streptococcus thermophilus and Lactobacillus delbrueckii sp. Bulgaricus) improves lactose digestion [5,6,7,8].
