The GAPS™ Protocol is a digestive healing protocol that does wonders for nourishing and helping the body ... helping many families regain their health even when conventional medicine has failed to help them do so. The range of conditions GAPS™ can help address includes:
Autism, eczema, headaches & migraines, digestive issues (such as acid reflux, diarrhea, constipation, gas & bloating), autoimmune disorders, fussy eating, acne, FPIES, poor immunity, candida, failure to thrive, OCD, aggressive behavior, anxiety, night terrors, dis-regulated hormones, etc.
However, for those with histamine intolerance amongst the GAPS community, it can be a troublesome issue. Many of the very foods that are used to heal and nourish on the GAPS Protocol are high in histamines.
The GAPS Protocol can be the very solution for balancing the human microbiome and the histamine issue in the long run. It is possible that the ill health of the gut may even turn the vulnerable genes “on” that contribute to histamine issues. The DAO enzyme system is located in the intestinal mucosa. What is one to do? This article will help you figure out how to juxtapose the GAPS diet with histamine intolerance. How does one get past the histamine intolerance symptoms? Let’s start with a brief summary of what histamine intolerance is, as well as symptoms, and what causes histamine levels to build up.
What is Histamine?
Histamine is one of those chemicals that performs multiple jobs ... that we cannot do without. It’s a bio-active chemical (useful and natural within the body), a neurotransmitter (messenger between cells), a mediator in inflammatory & allergic responses. It regulates access to the blood capillaries; also regulating stomach acid, muscle contractions, and even brain function. It defends against pathogenic viruses, bacteria, etc. In other words, we need it! “Normal” blood levels are 0.3 - 1.0 ng/mL, but individual tolerance is variable. So too, are the causes of one person’s intolerance compared to another.
