Heart rate insights can help us with histamine intolerance.⁣
⁣
The app Instant Heart Rate is a good starting point (available on iPhone). It describes itself as the “most accurate mobile heart rate monitor”, which means you can take your heart rate anytime, anywhere.

And it means you won’t have to try and count your pulse - never seems to work very well!⁣

This app helped me realize that double cream on my strawberries was giving me a serious histamine reaction. It was spiking my heart rate up to 120bpm. Which is a shame, as I quite like double cream.⁣

It also helped me realise (this was pre realising I had histamine-intolerance) that prawns massively spiked my heart rate. You live and learn and I’m grateful that now I understand more about what foods I react to.

Are prawns high histamine? Almost certainly yes - and for more on all different types of fish and seafood it’s worth checking out our Histamine Intolerance Food List and bookmarking it for when you are in a restaurant or supermarket.

ps - one more thing, look closely at the picture and check out my new hypoallergenic silicone wedding ring - it cost £3! And helps with hives - a symptom of histamine intolerance. Love isn’t dead.
