It is said that blue is an appetite suppressant and that red stimulates appetite. But is this really true? I would be interested if anyone knows of any studies into this.
I have also read that the reason that blue is an appetite suppressant is that blue food is very rare. I think blue food is less frequent than, say, green or red. But there is, of course, blueberries. And I just came across a type of mushroom that is naturally blue. It’s called Lactarius Indigo. I’ve also come across blue food more commonly in other places such as Japan.
