I have severe leaky gut and cannot tolerate beef, lamb or chicken, this is not due to the food itself but chemicals inside the food, perhaps additives, preservatives and so on. I am currently eating organic meat and poultry from specialist suppliers.
Just wondering about fish that can be bought from markets in general, do they generally contain non naturally occuring sunstances e.g. additives/preservatives or anything that may irritate my gut?
Many thanks
