Probiotic products are healthy foods that contain good bacteria

>Exámenes selectividad inglés Galicia resueltos


Probiotic products Probiotic products are healthy foods that contain good bacteria, and some of them are among the bestselling foods in supermarkets. Probiotic foods and drinks contain types of bacteria that naturally colonise your intestines and help you digest food, though we may not like eating them so much.
The theory is that by putting these ‘friendly’ bacteria into our system, we fight the bad bacteria and help promote the natural balance of micro-organisms in our digestive system. This, it is said, helps digestion.
There is also a theory that probiotics can help your immune system — some scientists believe that our immune system suffers in our super-clean homes, and that introducing good bacteria helps it. Because of this, there is evidence that they may improve those illnesses associated with the immune system, such as psoriasis and asthma.
Some of this is supported by studies, particularly in the area of intestine health. Recent studies have supported the theory that the bacteria in probiotics can make the immune system stronger. A paper presented at the European Influenza Conference indicated that probiotics, combined with vitamin and mineral supplements, could reduce the duration of some common illnesses. And then another study showed that people taking probiotics took fewer days off work than a group who took no probiotics, especially in night workers.
So far, studies on their effects on eczema, asthma and cholesterol have not produced good results, but the potential role of friendly bacteria in promoting digestive health is irrefutable. Our digestive health may be affected if we don’t eat them.
