What's For Breakfast?

[Clodfobble]

Your gut bacteria crave whatever they are used to eating, because by definition you have grown species that thrive on what you've historically eaten. Rice is a unique starch that encourages very specific bacteria. If you build up your colony by eating a bunch of rice every day, then suddenly starve them by not eating rice for two days, they will literally begin dying and releasing toxins that make you grumpy and tell your brain to get them the food they need before the colony perishes.
