Fermented Foods
Fermented foods like kimchi, sauerkraut, kombucha, miso or kefir are good for you because they have lots of probiotics, which are actually live bacteria.
On a empty stomach, though, these bacteria are uncontested and will take your own gut bacteria off guard, which might unbalance your digestive ecosystem.
Probiotics are effective at breaking down food and absorb the nutrients in what we eat, so they’re better consumed with something else.
