I have had so many people reach out to me after developing histamine issues on the carnivore diet. Usually they start out feeling great, as their zinc gets replenished, but over time a zinc excess, actually can cause the body to flush out copper, causing deficiencies.
This is not the only reason histamine issues present but I believe it is one significant factor.
Seafood tends to be higher in copper, but it’s often also high in zinc so if there is a serious deficiency it might not be enough to fix it. Seafood is also typically very high in histamine so might not be helpful.
Plants are higher in copper, so if you’re craving them and not feeling well on a carnivore diet, this might be why.
