If you’re one of the millions of people who suffer from histamine intolerance, you know how hard it can be to find low histamine snacks.

Histamine is an organic compound that our body makes from a complicated process involving an amino acid, histidine. It’s found in all body tissues and is a key player in many of our physiological processes. 

But when we have too much histamine, or our bodies can’t break it down properly, that’s when we start to experience problems. Symptoms of histamine intolerance include runny nose, watery eyes, itching, swelling, and hives.

Luckily, there are plenty of low histamine snack ideas out there if you know where to look. This list includes 13 different options, ranging from fresh fruits and vegetables to nuts and seeds.

So whether you’re looking for something sweet or savory, there’s sure to be something on this list that fits the bill.

What is histamine

Histamine is an organic nitrogenous compound involved in local immune responses, as well as regulating physiological function in the gut and acting as a neurotransmitter for the brain, spinal cord, and uterus. (1

Amino acids are the building blocks of protein. In our body, the amino acid histidine breaks down and produces histamine. Histamine acts like a chemical message. It also plays an important role in: 

– Localized immune response (2)

– Protecting our myelin sheath (nerves) (3)

– Gut permeability (4)

– Neurotransmitter (5)

– Blood pressure (7)

– Sleep/Wake cycle (8

Food-born bacteria like Morganella morganii, Citrobacter freundii, and Enterobacter spp. all release histamines as part of their infection process. That is why we feel ill when we have food poisoning, it is our body’s reaction to the histamines being released. (9)

In low concentrations, histamine can have positive effects on the body such as stimulating gastric acid secretion (which aids in digestion). (4) However, at high concentrations, histamine can produce negative effects such as causing inflammation. (2)

For this reason, histamine is a double edge sword, on the one hand, it plays a critical role in maintaining our immune system, on the other hand, it can also cause reactions in people who have a difficult time processing it. (1, 10)

Who is at risk for histamine intolerance?

Histamine intolerance is the result of a deficiency in the activity of one or more enzymes that are involved in histamine metabolism. This causes a build-up of histamine and therefore the symptoms of histamine intolerance. (10)

People who are at risk for histamine intolerance include those who have:

– A low level of the enzyme diamine oxidase (DAO) that breaks down histamine. (11)

– A sensitivity or allergy to certain foods can cause a histamine response. (12)

– Been diagnosed with mastocytosis or carcinoid syndrome, both of which are conditions that can increase the amount of histamine in the body. (13)

– Taken medications such as antibiotics, aspirin, and ibuprofen which can all increase the amount of histamine in the body. (10)

If you think you may have histamine intolerance, it is important to speak with your doctor. They will be able to help you determine if you have a true intolerance or if your symptoms are being caused by something else.

Now that we’ve discussed what histamine is and who might be at risk for histamine intolerance, let’s move on to our low histamine snack ideas!

Low histamine snack ideas

Two components of histamine intolerance are, the amount of histidine the amino acid found in high protein foods like beef and pork. Second is the amount of histamine-producing bacteria, mostly found in foods that have been fermented. (10)

While living a histamine-free life is not possible, limiting the amino acid  Histidine, and histamine-producing foods can help to lessen the severity of symptoms. (10)

The low histamine snack ideas below offer both, avoiding fermented foods, plus each snack has less than 20% of the RDA for histidine. (14)
