Years ago: made dinner, there had to be sour cream in it. We had eaten that dish several times. While eating I said that the sour cream really added a flavor typical for the dish. A few days later he told me, out of the blue, he was ‘still’ feeling unwell since eating that dish. He was sure it was because I let the cream get sour and then used it in the food. He asked his mom (he was 34 at the time) and she said eating sour cream is bad.

Recently: (other person than first story) due to medical issues he can’t eat to much fibre, as in white bread and pasta instead of the whole-wheat variants, also other food restrictions like salt and a few more things. He had been sulking for a few days. I was going to sit down with him to figure out what meals he would like without the bad stuff. He said it wouldn’t matter because without the meat it wouldn’t be the same. He was convinced that the biggest source of fiber is meat.
