Ayahuasca diet: what can you eat before an ayahuasca ceremony?

Calmness in your system helps you stay present with whatever arises.

Food is not a test of whether you're doing it right. It’s a way to help your body participate in an ayahuasca ceremony more calmly and safely.

Unsure about food or medication? Schedule a check-in.

Nutrition as part of preparation

Many people wonder what you can and cannot eat before an ayahuasca ceremony.

The ayahuasca diet helps prepare your body for the ceremony, allowing your system to participate more calmly and safely.

At SunGaya, we see nutrition as part of the preparation. It supports your process, without becoming a goal in itself.

Why is the diet important?

What normally isn’t a problem can, in combination with ayahuasca, lead to:

  • headache
  • nausea
  • increased blood pressure
  • overstimulation of the nervous system

That’s why dietary guidelines are used, and why alignment around medication is always necessary.

What can you eat before an ayahuasca ceremony?

Before an ayahuasca ceremony, you eat light, fresh, and simple foods. Think of:

  • Vegetables
  • Rice, oats, and potatoes
  • Fresh fruit (in normal amounts)
  • Plenty of water

This helps your body enter the ceremony in a more stable state.

How long should you follow the ayahuasca diet?

Most people start the ayahuasca diet 3 to 7 days in advance.

The last 48 hours before the ceremony are the most important. During this period, you avoid as many products as possible that could affect your body.

It’s not about perfection.

You don’t have to be perfect, but you do need to be honest. The idea that your body needs to be as “clean” as possible isn’t entirely accurate.

The less noise there is, the easier it becomes to feel what is happening during a ceremony.

Preparation is not about control or optimization. It’s a way to bring your body and system into a calmer state, so that whatever arises can actually be felt.

If you’re unsure about something, or if something didn’t go as planned, always discuss it during your check-in. It’s better to align one extra time than to sit with uncertainty afterward.

Medication, MAO inhibition and Safety

Important information

Ayahuasca does not combine well with certain medications and substances. Due to the MAO-inhibiting effect in the body, some combinations can react differently and, in some cases, be unsafe.

That’s why it’s important to always be honest about any medication or substances you use.

Not to control anything, but to assess what is safe and appropriate at this moment.

This is carefully discussed beforehand and, if needed, aligned with a consulting physician.

What does MAO inhibition mean?

Ayahuasca works, in part, because DMT, the active compound, can become active in the body.

Normally, this substance is broken down immediately. Due to the MAO-inhibiting effect, this breakdown is temporarily blocked, allowing the experience to occur.

This is also why certain foods and medications can temporarily react differently in your system.

What should you avoid before an ayahuasca ceremony?

Before an ayahuasca ceremony, you should avoid:

  • Alcohol and drugs
  • Caffeine
  • Fermented products
  • Aged cheeses
  • Processed and non-fresh animal products

Below is an example list of substances best avoided around an ayahuasca ceremony.

These guidelines are based on how MAO inhibitors affect the body.

  • At least 12 hours before and after the ceremony: strictly avoid
  • 48 hours before: most important phase
  • Preferably 2–7 days before: for more calm and safety in your system

These timeframes are minimum safety guidelines and are always assessed individually.

Very high risk (do not combine)

These substances should never be combined with ayahuasca, regardless of timing:

  • Antidepressants containing Selective Serotonin Reuptake Inhibitors (SSRIs), such as:
    Paroxetine (Seroxat), Fluoxetine (Prozac), Citalopram (Cipramil), Fluvoxamine (Fevarin), Sertraline (Zoloft)
  • The herb Kanna (Sceletium tortuosum)
  • Certain sleep medications
  • Some anesthetics
  • Certain anti-migraine medications
  • Some anti-allergy medications
  • Certain cough suppressants

👉 If you use medication or have doubts about herbs or homeopathic remedies, always check in first.

Sex and physical energy

In the days leading up to the ceremony, it is often advised to be mindful of sexual activity.

Preferably no sexual activity, including masturbation, 2–3 days beforehand.

Why:

Sexual energy can be demanding on your system and may affect your focus and inner stillness.

By being conscious of this temporarily, you create more space to be present with whatever arises during the ceremony.

The day of the ceremony

  • Eat light
  • drink enough water
  • Do not arrive with a full stomach
  • Preferably have your last meal a few hours before the ceremony

After the ceremony

Your system is more sensitive and open. It can help to continue the diet a bit longer, allowing the experience to settle and integrate more deeply. Eat light, drink enough water, and take rest.

👉 Read more about this process on the integration page.

Summary

The ayahuasca diet helps prepare your body for a ceremony by creating calm and stability. By temporarily avoiding certain foods and substances, you reduce risks and increase the chance of a clear experience.
