Is a food probiotic yogurt?

Is a food probiotic yogurt?The defining characteristic as a probiotic is a microorganism that can survive the effects of gastric juices and bile reaching the intestine asset to perform beneficial functions.

But the truth is that scientists do not agree to play in defining what microorganisms are probiotics and what not.

One group of investigators recently ensured that yogurt can not be considered a probiotic food because no positive effects as lactic acid bacteria-containing Lactobacillus bulgaricus and Streptococcus thermophilus, the die as it passes through the gastrointestinal tract.

A statement that contradicts those made by another group of Italian researchers who claim that yogurt bacteria do manage to reach the large intestine when taken in high amounts. This is evidenced by the fact that these bacteria have been found intact in the feces of healthy subjects who daily for ten days fed a diet of 250 grams of milk fermented with yoghurt bacteria.

It should be added that most of the studies on probiotics are made using living germs, complete. However, dead germs germs and even components are sufficient to stimulate immune reactions in our body.

To resolve this controversy have launched several studies to determine what can be considered probiotic bacteria and which have only nutritional properties.
