I've read at least two anecdotes by different people on Parnate who suffered hypertensive crises after eating pepperoni pizza. However, studies done up at Sunnybrook, Toronto by Dr. Shulman, et al, showed nearly zero tyramine in Pizza Hut and Domino's double cheese double pepperoni pizzas. I do believe the two people who suffered hypertensive crises on Parnate did eat at smaller, unaffiliated local pizza places, with perhaps more aged/authentic pepperoni. I get pizzas myself from the Papa Murphy's take them home and cook them chain, and I do not select their pepperoni, because my impression is that it is higher quality and possibly more aged than what you might find on a Domino's pizza. I also specify mozzarella only, as Papa Murphy's normally use a three cheese blend."

> BACKGROUND: Continuous refinement of the monoamine oxidase inhibitor (MAOI) diet has resulted in much reduced and simplified recommendations that attempt to balance safety and practicality. In the spirit of evidence-based practice, dietary restrictions should be based on carefully documented case reports and valid tyramine analyses. Residual concerns have focused on combination foods such as pizza and a variety of soy products. We determined the tyramine content of pizzas and a variety of soy products in order to refine dietary recommendations for use with MAOIs. METHOD: High-pressure liquid chromatography analysis of tyramine content was performed on a variety of pizzas, soy sauces, and other soybean products. A tyramine level of 6 mg or less was considered safe. RESULTS: No significant tyramine levels were found in any of the pizzas, including those with double pepperoni and double cheese. Marked variability was found in soy products, including clinically significant tyramine levels in tofu when stored for a week and high tyramine content in one of the soy sauces. CONCLUSION: Pizzas from large chain commercial outlets are safe for consumption with MAOIs. However, caution must be exercised if ordering pizzas from smaller outlets or gourmet pizzas known to contain aged cheeses. All soybean products should be avoided, especially soy sauce and tofu. Individualized counseling and continuous surveillance of compliance are still essential.

>Yes, I had read that abstract about the pepperoni being safe. That was one of the reasons for my confusion because I had also read about others (including SLS) having reactions to pepperoni. I think that what Todd said makes sense. The abstract measured the pepperoni from the pizza chains. The pepperoni from the chains is probably ok but the better, more aged pepperoni may be dangerous.
I also noticed that one of the links that Larry provided showed from their tests that mozarella was a problem too. Yet every other source seems to say that mozarella is no problem. Judging from the number of people who are successfully eating it, I'm not really that concerned about it though. Also, I haven't read where a single person has had a bad reaction to it yet.
