My daughter at her school today learnt about the benefits of probiotic supplements, as they help in keeping the digestive organs function properly. Nonetheless, I am interested in knowing about probiotic foods. I want to know about some probiotic foods, which could be given to children, so that it would then not be required of them to take probiotic supplements. I would also like to know, if there is any side effects of probiotic foods. I would really appreciate, if somebody can help me with some relevant and reliable information related to probiotic foods.
