Food intolerances👤 🪪 ⚗️ 💊
Foreword
I don’t have any ethical or religious dietary restrictions, but I do
have quite a few food intolerances linked to my neurodivergence.
For me, these intolerances show up in two ways: as effects on my
senses, such as pain, itch or discomfort, or as effects on my mind,
such as overstimulation or sedation. To capture the full range of
these adverse effects, the list includes substances I ingest as well
as those I inhale passively when people nearby smoke or vape them,
such as tobacco and cannabis.
Below they’re listed in two sections. The first, by
pharmacological/chemical class , explains how each substance
affects me and helps identify intolerances not listed. The second, by
food type , is a practical index for cooking, shopping and eating
out. Each food links back to why it’s listed, and so whether related
foods are likely to be fine. Please pay special attention to the
counterexamples (shaded in grey): they can look related, but they’re
exceptions I can consume.
The active ingredients are my best hypotheses, and this page is a
work in progress, so some items may be missing. If in doubt, please
ask me.
