This is definitely worth a listen. More reasons to eat plenty of probiotics. Not only do they assist in proper food digestion, they may also be linked to a boost in serotonin and mood. In my personal experience, I have felt generally calmer and more clear-headed when I am getting a healthy supply of probiotics in conjunction with a good veggie-heavy diet and other wellness promoting practices. This episode was really cool! Give it a listen! Further affirmation of the Ayurvedic theory that all good health begins with great digestion.
Also, in terms of probiotic sources, there are many to choose from. I like Bubbies pickles and sauerkraut, homemade sauerkraut, kefir, umeboshi paste, and cultured cottage cheese or cream cheese. Diversity is a good thing, so eating from a variety of probiotic sources will give you more diverse strands.
