Thanks, I didn't know it started on Shark Tank. Ya one of the main issues is that the tests can show an immune response, but not the specific foods that triggered it. So they might report too strongly on foods in your system and miss foods that you haven't been eating lately.

I want to emphasize though that this is a situation where leads are more important than evidence. For example, my sensitivity to wheat was shown as normal but I have since discovered that it causes instant inflammation in my gut and I gain 5 pounds the next day, then go into a slow decline if I keep eating it. And it showed normal sensitivity to beans because I've been avoiding them, but I still can't eat most types except maybe garbanzos and lentils sparingly.

Also wanted to mention that I forgot introvert/extravert in my comment about TikTok and one's reaction to it. I was thinking more about how skepticism affects it, but our tastes are more complex than 1 scale, or even 4 bits for the 16 personalities of Myers-Briggs. Even 20-30 bits might not be able to predict them, since every personality is unique.

Edit: "stars in the sky" is what I meant in my previous comment (of course we can see the sky). I'm a bit OCD but with diverging thoughts so brevity is a real challenge for me.
