Low Histamine Foods That Nourish The Gut
One of the challenges faced by people with histamine intolerance is the removal of high histamine ferments, but fortunately, a wide range of low histamine foods nourish the gut. You do not need to eat sauerkraut to have a good gut biome.
In the scientific literature, it is a well established that there is a bi-directional relationship between blood sugar control and histamine.
Unstable blood sugar can increase histamine levels, and histamine levels can add to unstable blood sugar, and its really common in my client base.
What’s more, a 2015 study found a person’s microbiome precisely explained not only these variances in blood glucose levels but also food tolerance in a group of 800 people.¹
These findings suggest that food tolerance may reside in our microbial genes, and their interaction with our genes, not in our human genes themselves.
Indeed, it is my experience, that the diet required to stabilize blood sugar, varies enormously from one person to the next – anywhere on a spectrum from a vegetarian, to a mixed, to a ketogenic diet, and vary over time, rather than being set by our genes.
It’s About Diversity
Differences in long-term diet have a major impact on the gut microbiome. It’s about a consistent day in and day out effort to feed the biome.
The American Gut Project, and the Twins UK project, found that building diversity had a comparable effect to taking medication, and low diversity to disease. It’s that important.
Personally, I have been using Ubiome®, it’s an affordable, easy, do at home test, that helps track the diversity in your biome.
I have been tracking the improvements in my gut biome, using the principles outlined in this post, every 90 days. And I have also been testing my mouth biome too!

The Missing Ingredient: Polyphenols
A 2012 study, provided the mechanism, for understanding how to stabilize blood sugar, using low histamine foods, whilst nourishing our gut biome.
The study found that dietary polyphenols (often identified by the bright color in foods and includes quercetin and luteolin) were the missing ingredient.
Polyphenols when combined with complex carbohydrates for fiber, not only stimulate the growth of beneficial bacteria (including lactobacilli and bifidobacteria), but inhibit pathogenic bacteria, increase species diversity, and improve blood sugar control. Fortunately, they are abundant in many low histamine foods.
A recent review of the literature even found polyphenols as helpful for chronic fatigue syndrome.³
Other Gut Nourishing Foods
Polyphenols join other foods that have been shown to selectively nourish the gut including fructooligosaccharides, galactooligosaccharides (GOS), colonic foods, and resistant starch, providing a wide range of foods that nourish your gut. 4
Nourishing Your Gut On A Low Histamine Diet
Based on this research, my approach to rebuilding an antibiotic decimated gut biome is to eat:
- A whole food, minimally processed diet, rich in fiber,
- Emphasizing polyphenols rich foods (the darker the color the better!)
- With moderate fat (focusing on polyphenol-rich olive oil),
- Moderate protein (more as a condiment than the major component of the meal), and
- Rich in variety (I try to aim for up to 40 different whole foods a week).
and it is working.

How to Reintroduce Foods
If my clients eat a wide range of food groups then I simply encourage them to find the composition of macronutrients that balance their blood sugar, and from there introduce one new food a week, building their diversity of foods over time.
For clients who do not have a wide range of food groups in their diet, having removed one food after another, until they are eating only a handful, if not a few, it is really important to work slowly with a dietician to introduce new foods.
In highly sensitive people, with few foods in their diet, this might be at a snail’s pace of 1/4 teaspoon a week. In which case I often suggest slipping this into a smoothie, or salad and building the amount by a 1/4 teaspoon a week from there.
If unable to tolerate this amount, then I encourage clients to enjoy feeling well at this lower level and wait a few months and try a small amount again.
If foods are not able to be introduced, and the microbiome altered through food, then the question is what else is the biome that is unreceptive to the company? Sometimes it is necessary to address that and repair intestinal permeability, before introducing new foods.
