Strategies you can use to rewild your body:
Eat fresh, minimally washed plant foods from a trusted source (e.g., backyard garden).
Occasionally eat small quantities of a diversity of fermented vegetables, preferably organic and homemade. Sauerkraut, kimchi, and other lacto-fermented foods are a rich source of bacteria, some of which could help you boost the diversity of your gut microbiome.
Do some gardening.
Avoid antibacterial products and harsh cleaning products.
If you’re a female, perform vaginal births (if possible) and breastfeed your child(ren).
Pick up bacteria from healthy humans and animals.
Spend more time in natural environments.
Take good care of your home’s microbiome.
If your microbiota is severely damaged, consider performing one or more microbiota transplantations or taking a drug designed to restore microbial diversity of the gut.
