The irreversible MAOIs(Nardil, Parnate, Marplan & high dose selegilline) inhibit the MAO-A in the gut thus allowing the tyramine to be easily absorbed into the rest of the body.

"MAOs are located in many tissues, including the gut wall. MAOIs absorbed through the gastrointestinal tract bind significantly to MAO in the gut mucosa and liver producing significant first pass effect. To be effective in the CNS, their location of clinically significant effect, they must be given in high enough concentration to reach plasma levels and thus brain levels, sufficient to produce binding centrally to MAO. MAO-A in the gut acts as a barrier to the absorption of tyramine, and thus ingestion of substances containing tyramine may produce significant toxicity."
