The Diet

The Ayahuasca brew is having quite an interesting way of acting once ingested. 

It is made of two plants (Banisteriopsis caapi and Psychotria viridis ). One plant supplies the psychoactive substance (DMT) and the other is deactivating the defense system (monoamine oxidase enzyme) of the body that would otherwise destroy the psychoactive substance. So the two-plant combination is needed to provide the effect of the brew.


The important part to understand is that besides allowing DMT to be active, the brew can expose your body to the danger of other substances that would normally be broken down by your body's defense mechanism.

One of the substances that can cause harm is called Tyramine ( more info ). So one should avoid foods rich in it, for example, foods that are fermented, cured, aged, or spoiled. Below are some examples:


  • salt-dried fish (mackerel, cod, and sardines)

  • unpasteurized, strong, or aged cheeses ( cheddar, feta, blue cheese, and Gorgonzola)

  • casseroles or pizzas made with aged cheeses

  • cured or smoked meats or fish (sausage and salami)

  • certain beans (fava and broad beans)

  • some sauces and gravies (soy sauce, teriyaki sauce, fermented fish sauce, and bouillon-based sauces)

  • pickled products (sauerkraut and kimchi)

  • sourdough breads, yeast-leavened breads, or breads made with aged cheese or meat

  • fermented soy products (miso soup, bean curd, and tempeh, as well as forms of tofu that are fermented, such as “stinky tofu”)

  • fish or shrimp paste

  • concentrated yeast products( spreads (Marmite, Vegemite) and brewer’s yeast

  • protein supplements with yeast products)

  • mincemeat pie

  • meat tenderizers or foods prepared with meat tenderizers

  • certain alcoholic beverages ( tap or home-brewed beer, Korean beer, and vermouth)


These are just several examples and the list can be continued.


At our center, we provide simple tasty dishes made of foods that are safe to eat during an Ayahuasca retreat. Generally speaking, we have a vegetarian/vegan diet with lots of fruits and vegetables.

Our cook is having a not-so-secret ingredient that makes the dishes extremely tasty - love.


We encourage our participants to start their ayahuasca diet before arriving at the center. Limiting or stopping eating pork, red meat, dairy, refined sugar, salt, fats/oils, processed & canned foods, fermented products, caffeine, and alcohol will help you during the retreat.
