@lcracraft @BowTiedPhys I have to have an app for my kids’ school lunch menu 😭

[BowTiedPhys @BowTiedPhys]

I don’t want the email of 50 words summarized by AI. I don’t want to know my biological age. I don’t want the wearable telling me when I should be happy. I don’t want the Bluetooth toothbrush gamifying brushing my teeth. I don’t want my trash can to be “smart”. I don’t want my Air Fryer connected to WiFi. I don’t want an app for my coffee maker. I don’t want my refrigerator sending me push notifications.

Enough.

@escapefrommelos It’s just loud in the room so they’re close to hear each other

But eventually, with the help of a top London doctor (doing clinical trials on histamine intolerance with Imperial College London), I finally got the right tests, a treatment plan, and a strict diet that made me feel like myself again.

Last year, I was diagnosed with histamine intolerance; a real condition, despite what comment warriors (and even some GPs) may tell you. My NHS doctor didn't spot it. One allergy specialist sent me on a wild goose chase.

@NutritiousLife_ I went through the wringer for years trying to find answers. Finally identified histamine as the culprit this year and now I’m on the road to recovery. 🙌

@BioavailableNd Histamine sufferer here 🙋‍♀️ I was prescribed an SSRI back in 2021 for anxiety and depression. A doc in 2025 told me about the histamine link. This is fascinating thanks for sharing!

@BioavailableNd Any idea at all on the histamine content of Skyr?

[Jenna St John @jennastjohn]

@TheWildPrairie @BioavailableNd I have this

Health Twitter foods that could enhance flares of symptoms for people that don't know they have Mast Cell Activation Syndrome and histamine overload:

- Bone broth (cooked for too long: releases histamine)
- Cacao
- Shellfish
- Strawberries, papaya, pineapple
- Aged cheeses
- Fermented foods
- Really nutrient dense foods that are leftovers
