"Finnish researchers found that a vegan diet changed the gut microbiome, and that this change was linked to an improvement in arthritis symptoms."
I had a suspicion when I started reading this article that the simplest solution would be to cut meat out of the diet.
It's astounding how many problems are solved medically, environmentally, economically, and of course ethically if we simply stop consuming meat, or at least stop consuming it at such extreme levels!
