I've been watching some of Shockey's fermentation videos from her online Fermentation School. Current thinking is that 6 different fermented foods per day give excellent results. Of course, fermentistas would say that.
I've had 4 already today, I think. Fermented capsicum, fermented brine (added to the dal), fermented herbs, a shot of beetroot kvass.
I'll have some kimchi with dinner and add some lacto-fermented preserved lemon to the salad/dressing. Or maybe some miso soup.
I think it is in diversity rather than quantity, to get a huge variety of the beneficial microbey thingies.
I need to keep a focus on this for a while as i am on my fifth course of antibiotics in the past 6 months'ish. Current health challenge, an infected finger 😭
