Are you lactose intolerant? Consume yogurt could be a solution.


Yogurt is already known has benefit effects to our digestive system and improve your health. Yogurt is made by fermenting milk with the help of lactic acid bacteria such as Lactobacillus sp. It has unique aroma and sour taste.Yogurt is also known as probiotics. Probiotics are live bacteria that don’t cause infection to human, and will provide some benefits to digestive system and improve your health.

Yogurt as probiotic

The probiotics bacteria are Lactobacillus acidophilus, L. casei, L. bulgaricus, Bifidobacteria, Streptococcus thermophilus, etc. Most of probiotics bacteria are lactic acid bacteria; they metabolized carbohydrate through fermentation and produce lactic acid as the major metabolic end product. This group bacteria is suitable as probiotics because it can survive through the low pH stomach acid also able to attach and colonizes in the gut.

Yogurt's benefit effects

Consume yogurt is a solution for people who are intolerant to lactose that is contained in milk. There are many symptoms of lactose intolerance, such as: gas, cramping, nausea, diarrhea, abdominal pain and bloating. Why people who intolerance to lactose experienced those symptoms? Lactose in milk left undigested in the intestines, this lactose will cause some amounts of water drawn into intestines, this caused diarrhea, and also causing gas.
How it will work? When people consumed yogurt, bile acids disrupt the cell wall of the bacteria in yogurt. This is cause releases enzyme beta-galactosidase which is related to lactase, into intestines and it can enhance lactose digestion.
There are one interesting facts, although yogurt is a milk product, many people with lactose intolerance do not experience certain symptoms even to yogurt that doesn't contain live bacteria. Actually, before fermentation, lactose content in the yogurt is about 6 %. During fermentation process, 20-30% disaccharide lactose hydrolyzed to its absorbable monosaccharide components, glucose and galactose. In another example, some strain bacteria in yoghurt such as L. bulgaricus and S. thermophilus are able to expressed functional lactase, an enzyme that digested lactose. That is why lactose concentration in yogurt is lower than in milk and it's tolerable for people with lactose intolerance.
Therefore, we can conclude a few things. Milk contains many nutrients that are good to our body, but also contains lactose. Some people who is lactose intolerant can't digest lactose in milk, it can caused diarrhea and other symptoms. The solution is drinking yogurt regularly. People with intolerance lactose still can get benefits from milk by drinking yogurt, because it contains lower concentration of lactose than in milk, so it’s tolerable for these people.
