The Ayahuasca Diet: How to Prepare for Ceremony.
Prepping your body, mind and soul.
The diet is an important part of preparing for an ayahuasca ceremony. It strengthens your connection to the work beforehand and readies the body for the medicine.
What Is the Ayahuasca Diet?
The ayahuasca diet, often called the dieta, is a period of dietary and lifestyle preparation followed in the weeks before an ayahuasca ceremony. It involves stepping away from certain foods, substances and habits, both to prepare the body safely and to begin a respectful relationship with the medicine.
There is some confusion around what does and does not belong in the diet, partly because many Amazonian traditions work with ayahuasca in their own ways, and partly because the diet has shifted over time. At Sowa Soma we believe each person's preparation will differ according to their circumstances, and that there is no single right way.
Why We Prepare With the Diet
For us, the main purpose of the diet is to begin a journey of respect and relationship with the plants, and to gauge our own discipline and integrity along the way. There is reciprocity in it too. We set aside certain comforts and pleasures as a gift for what the plants are about to teach us.
The diet also prepares the body. It lightens the system and helps you arrive at ceremony clear and strong enough to do the work. Those with more experience may choose to go stricter, while first timers may wish to keep things simple.
Some parts of the diet are about more than tradition. Ayahuasca interacts with certain foods and medications, so avoiding them is a matter of safety.
In particular, antidepressants (SSRIs) and other medications can react with the medicine, as can certain aged, fermented and cured foods. This is why disclosure and honest conversation matter so much. During our screening we talk through your medications and health with you, and we will always ask you to consult your doctor where needed.
Please never stop any prescribed medication on your own. It should only ever be done with medical guidance.
The Safety Behind the Diet
what to avoid
-
In the weeks before ceremony, we generally recommend stepping away from:
Recreational drugs and alcohol
Other plant medicines, including cannabis and mushrooms
Pharmaceutical drugs, unless agreed with us beforehand
Casual sex and intimacy (ideally 3-5 days before)
Violent or sexual media
Strong synthetic scents and perfumes
Non-natural toothpaste, ideally fluoride free
-
Processed table salt, though small amounts of sea salt are fine
Garlic, leeks and onions
Chilli, spice and strong seasonings
Pork, including gelatin
Caffeine
Wheat
Dairy
Chewing gum, unless natural and free from aspartame
Sugar, though small amounts of honey or maple syrup are okay
What to include:
-
Choose whole food options rather than ultra processed foods.
Fresh fruit and vegetables, organic where possible
Free-range eggs
Well-sourced fish, chicken and wild meat, pasture-raised and organic
Fresh dairy - cottage cheese
Fresh herbs
Grains
Daily prayer and meditation, movement, journalling, singing, dancing and music
Scent-free soap and natural deodorant
Please note, it is always vital to speak to the organisers of the ceremony or retreat you are attending regarding diet and what’s expected of you as this will differ between space holders.
HOW LONG BEFORE?
We generally recommend beginning the diet ideally around two weeks before your retreat, easing into it rather than changing everything overnight. People tend to find cutting out caffeine the most difficult, so give yourself time and space to come off this so that you don’t experience withdrawal symptoms whilst on retreat. The more experienced may choose to start earlier and go deeper. During your screening we agree a timeframe that suits your circumstances, so you arrive prepared but not depleted.
A diet shaped around you
Everyone's circumstances are different. Some people carry addictions, and some carry trauma-based feelings around food, so a single strict rule rarely serves everyone well. During our inclusive screening we speak with you personally about your preparation, so your diet supports you rather than burdens you. The aim is always to arrive strong enough to work with the plants.
What about a master plant dieta?
The preparation diet is different from a master plant dieta. A master plant dieta is a deeper, dedicated practice of working with a single plant over a set period, in relative isolation and on a restricted diet, to receive its teaching. It is a committed path in its own right. If you feel drawn to that work, you can read about the dietas we hold.
Frequently Asked Questions
-
The ayahuasca diet, or dieta, is a period of dietary and lifestyle preparation followed before an ayahuasca ceremony. It involves avoiding certain foods, substances and habits, both to prepare the body safely and to begin a respectful relationship with the medicine. The exact diet varies between traditions and individuals.
-
The diet prepares both body and mind. It lightens the system so you can work with the medicine safely, and it begins a relationship of respect and discipline with the plants. Some restrictions also exist for safety, as ayahuasca can interact with certain foods and medications.
-
We generally suggest beginning around one to two weeks before your retreat, easing in rather than changing everything at once. More experienced participants may start earlier. During screening we agree a timeframe that suits you, so you arrive well prepared without feeling depleted.
-
We generally recommend avoiding alcohol, recreational drugs, caffeine, pork, aged and fermented foods, dairy, wheat, sugar, salt, and strong seasonings such as garlic, onion and chilli. Some of these matter for safety, others for cleansing the body. Your full guidance is agreed with us beforehand.
-
Fresh fruit and vegetables, free-range eggs, and well-sourced fish, chicken or wild meat are all good choices, organic where possible. Alongside the food, gentle practices such as meditation, movement, journalling and time in nature support your preparation beautifully.
-
Some medications, especially antidepressants (SSRIS), can interact dangerously with ayahuasca, so this must always be discussed honestly beforehand. Never stop prescribed medication on your own, as this should only be done with medical guidance. During screening we talk through your medications and work out what is safe with you.
-
If a slip happens, the most important thing is honesty. Tell us, and we will guide you. Small lapses can often be managed, but some, particularly around alcohol, drugs or certain medications, matter for safety and may affect whether it is safe to take part. This is why open conversation is essential.
-
Afterwards, return to richer foods slowly over a few days, keeping meals simple and nourishing at first. This supports both your body and the integration of your experience. We share aftercare guidance to help you ease back gently.
-
The ayahuasca diet is short-term preparation before a ceremony. A master plant dieta is a deeper, longer practice of dieting a single plant for its teachings, often in isolation and on a stricter diet. They are related but distinct paths. You can read about the dietas we hold on our dietas page.
