Probiotic yoghurt vs. Common yoghurt

These days I read some articles that talk about the benefits of yoghurt. The probiotic yoghurt is any yoghurt with live active bacteria (they're of various types like Lactobacillus or Bifidobacterium, which are considered beneficial to the body), which means that the more natural yoghurt is a probiotic food. All yoghurts contain a certain amount of bacteria, yoghurts sold as "probiotic yogurt" contain higher amounts of beneficial bacteria (It's because some companies select some bacteria that are more likely to survive digestion).

These bacteria have been shown to reduce the effects of some gastrointestinal problems, prevent colon cancer and can reduce lactose intolerance. In addition,  it's a natural immune system booster, so it's very common drink them to improve overall health and prevent certain diseases.

However, the yoghurt in some people can cause side effects such as gas, bloating and over-stimulation of the immune system.

The medical and scientific community mentions that products labeled as probiotic yogurt aren't necessarily better. So, you can select the yoghurt that you have on hand, but taking care that it doesn't have high levels of sweeteners such as high fructose corn syrup or sugar.
