My mother is the kind who changes the whole family's diet when she reads some sufficiently convincing diet book or study. At one point we ate dissociated food. At another point it was blood type food. At another point it was raw roots or something. I love my mother and she's an excelent cook, and she never forced us to eat according to the books, but she would be very insistent, because there were studies that showed ...
Most of the time the results of those studies were disproved, either by another experiment or by some technical issue with the way the study was conducted.
Just like there were studies that smoking is actually good for you and studies that showed that children who drink sugar soda from an early age are heathier.
The point I'm trying to make is that these studies are not just 'informative', they have real consequences on real families. There are families out there who will start eating hot food just because they've read this study.
I hope they don't torture themselves for nothing.
