Histamine intolerance (HIT)

Hello,
why is shrimp listed as an unsuitable food for HIT? Is it because they cannot be eaten fresh here, or is it something else?

Yes, seafood is prone to relatively rapid decomposition, during which increased histamine formation occurs. It is therefore advisable to preventively avoid such foods. In practice, such situations are addressed by first eliminating all potentially risky foods, then gradually reintroducing them into the diet while monitoring the body's reactions. It often happens that foods commonly presented as unsuitable can be safely consumed by some individuals affected by HIT.

Good day, Mr. Jelínek.

In the lesson, you mention that there are probiotic cultures known to clearly worsen HIT symptoms, and conversely, some that have a beneficial impact.
Lactobacillus casei and Lactobacillus bulgaricus have a negative impact.
The positive effect is seen with Lactobacillus rhamnosus, Lactobacillus plantarum, Lactobacillus reuteri, Bifidobacterium infantis, and Bifidobacterium longum.
Since my wife has HIT, I have been trying to find an appropriate supplement to support her gut microbiome based on the information above. I found products that contained, for instance, 2 positive strains and perhaps some additional ones or even 4 positive, which made me rejoice, but 1 negative. In this context, I want to ask whether one negative strain compared to 4 positive ones, when each is present in the same amount, can negatively affect the overall result, and whether it is better to choose a product with just, say, 2 positive strains or not. Thank you.

That's a good question :-) Since this is a relatively new topic in nutrition research, the answer is not entirely clear, especially in relation to HIT, where it's necessary to proceed individually by testing different options and observing the body's reactions. Moreover, new studies are constantly emerging that push the knowledge further, making it difficult for manufacturers to react quickly and change the composition of their products. One negatively acting strain may (but theoretically might not, which you will only find out after trying it) affect the overall result. If you want to be sure, then choose the "safer" option; unfortunately, there is no other way.
