I have the list from this website - says no! But a friend of mine who has information from their doctor (about a year old) says you can have Tuna if in Spring Water ..... Since I am not a "fishy" person, except for Shrimp which is not cheap in Missouri, I was looking to be able to add Tuna as a 3rd protien source.
I read on another HCG plan that the tuna is an alternative option for vegetarians. I don't know if it's a valid option for non tuna folks. Not sure if you have ever tried talapia, but it's really good. Good luck and let us know what you decide to do. I love me some tuna!
the best is try it on your first day on P2 but if you are half way through, you can still try adding it to your diet if you are willing. If you stall then eat apples right away just to get you back on track. If not then please share that info in here so we would know too.
