Hi there…a few comments. At an hour, this is not a FODMAP reaction, which you can read more about HERE. So, this question has a two pronged answer. I would not test again until I have given myself a 3 days rest, but also, knowing that this was not a FODMAP reaction makes this more complex. This is exactly the type of reason we suggest working with a dietitian. We cannot give medical advice, as we do not know your complete picture.

Also, we do try to encourage not using the term “safe” (which means there is “unsafe”) for a variety of reasons laid out in this article.

I’m currently testing sorbitol. I had 38g of avocado yesterday and about an hour later had to dash to the loo followed quickly by two more visits, and feeling it wasn’t safe to leave the house to walk my dogs. Nothing since then except discomfort and pain, I had a good night apart from bowel pain which I seem to often get (last week the pain was after testing rice, I’m having to test safe food too, and it spiked my blood glucose to over 8). I’m in pain still this morning.
Is my reaction to avocado enough to decide to stop this test? Should I try one more day?

There are many approaches. Many dietitians will suggest that you test what you eat. After all, that is what you want to learn about, in terms of your reaction. If you usually eat cooked garlic, simply use the amount in a serving size that you will be testing.
