This is my entry in the mini contest!
I usually take one dose of Kefir every morning to break the fasting process during the morning hours, as I wake up.
I take Kefir in the morning, before breakfast, because it has several beneficial factors to improve my digestion process since I do not have enough digestive enzymes to take me through this complex biological operation.
Kefir is not the same as a natural yogurt, since it is the result of the milk process's fermentation. During this process, there is the generation of the »Lactobacillus kefiranofaciens» bacteria, which contains several digestive enzymes, and you can make natural Kefir at home.
These digestive enzymes help considerably during the digestion process, since they inhibit the bloating and sometimes the heartburn effects caused by it.
During the visit to a supermarket, you can find natural Kefir as well as flavored kefir options like strawberry and mango. As well as cow milk Kefir and goat milk kefir.

I would like to thank @quiubi for the invitation to this mini contest.
