While many of those foods have anti-protozoal properties and will greatly benefit anyone attempting to decrease protozoans in their body, there are significant draw backs to such a diet. Many people with protozoal infections have methylation pathway obstructions due to genetics AND an overwhelming of the pathways. It can occur at multiple points in both the methylation and transsulfuration pathways. It presents as a CBS mutation but the entire pathway is diminished as even the urea cycle can be affected. Many of those foods are high in sulfur and thiol groups. Eating these foods with a non-functioning or diminished transsulfuration pathway is a recipe for disaster. Trust me on this one. I've been there, done that. If you can open up the pathways, there are dietary means that can kill pathogens. Yes, I said kill. Keeping these pathways open is not easy with what they are dealing with.
