What is MCAS?

Mast Cell Activation Syndrome (MCAS) is a chronic condition that affects all organ systems. MCAS is serious and disabling and people with MCAS experience often significant and debilitating symptoms daily, including anaphylaxis, which can be fatal.

MCAS is often found in combination with other chronic conditions such as Ehlers-Danlos Syndrome (EDS) and Postural Orthostatic Tachycardia Syndrome (POTS).

Frequently healthcare providers do not know about MCAS, and the tests for MCAS are problematic because they are not uniformly reliable. MCAS can be difficult to manage. Treatments include blocking mast cell mediators with anti-histamines and mast cell stabilizers, as well as avoiding triggers.

Check out this post on how to manage MCAS.

The bucket theory

The bucket theory offers a helpful analogy for understanding symptom reactions with MCAS.

Think of your body as an empty bucket that you want to keep from overflowing. Different foods and activities fill your histamine bucket at different speeds but they combine to form the total level of histamine in your body (how full your bucket is). A fuller bucket means you have more histamine symptoms. When you manage triggers, reduce exposure to known triggers, and take medications and supplements to reduce histamine, you can manage the level of your bucket.

Know your typical symptom progression

Knowing your symptom progression in a symptom flare is the key to developing your own rescue plan. In this post, I discuss how to determine your own symptom progression. Once you know what typically happens in your symptom progression you can design a rescue plan to address those symptoms.

Why this list of MCAS tolerated foods?

The following list of foods is lower in carbs, lower in histamine and histamine-releasing foods, lower in oxalates, free of nightshades, grains, and gluten, and lower in salicylates. This is not an invitation to make drastic changes to your diet, but to be used as a reference guide. Please consult with your healthcare practitioner before changing your diet. Many foods that are not on this list can be anti-inflammatory, histamine-lowering, and part of a healthy diet. So this list is just meant for people who are looking for a concise list of foods that are lower in histamine, oxalates, and salicylates.

A word about limiting your diet

Do not limit your diet without first consulting with your healthcare practitioner. This list is only meant as a reference for knowing MCAS tolerated foods. Your individual constitution is going to be unique to you, and you may not need to limit salicylates or oxalates at all. The healthiest diet for you will include the widest variety of foods that you can tolerate.
