MCAS Nutrition Options

Mast cell activation syndrome (MCAS) is a condition in which mast cells, a type of white blood cell, are overly active and release too many chemical mediators. One of these mediators is a compound called histamine, which can cause a variety of symptoms such as hives, itching, flushing, and gastrointestinal issues. MCAS may also be associated with other conditions such as postural orthostatic tachycardia syndrome (POTS). It’s possible that nutrition can play a role in managing some of the symptoms associated with MCAS and POTS.

In conclusion, nutrition is an important consideration for those with mast cell activation syndrome (MCAS) and related conditions like postural orthostatic tachycardia syndrome (POTS). Some people with MCAS or histamine intolerance get symptom relief by following a low-histamine diet and avoiding trigger foods, while others may find that specific foods are not common triggers for their symptoms. It's important to speak with a healthcare provider or registered dietitian for personalized guidance and recommendations.
