Hi there, Jacqui_D! Thanks for posting this. I've been researching fermentation a lot recently, as my mother-in-law is very into it - she is (literally) the healthiest person I know (and very smart), so I tend to listen!
I, personally, have started drinking kefir water that I ferment at home. Also, I have started experimenting with fermenting veggies (doing carrots at the moment) and I've been trying to brew my own ginger beer.
I honestly do believe there are direct links between our physical and mental health and our microbiomes. I am someone who, no matter what, always seems to get sick. I catch colds so easily, and they are always huge colds, not little ones that pass in a few days. I can always count on getting sick 3-4x per year with a cold, the flu, strep throat, etc. One year, I had strep throat FOUR TIMES - and we don't have kids AND we both work from home. How that happened, I'll never know.
Since I had my knee replaced this past December, I've been very interested in boosting my immune system so I've done a lot of research. Honestly, the only "somewhat" proven way to boost immunity is through the use of probiotics. And since that's what fermentation is all about, I thought I'd give it a try.
I'm also now reading about the link between our "gut health" and weight loss. Definitely an intriguing area of study!
