Superstitions exist about most every item, action, or even time of the day. So it's no surprise that something as important as food and eating has quite a few myths based around it. Like throwing spilled salt over your shoulder or making a cross on top of a loaf of bread before baking.
Having taken the liberty of looking through the entire slideshow, I can say without a doubt that there are quite a few strange ones, and more then a few that don't really make....any sense. At all (but I guess that's why it's a superstition!). See all 21 food superstitions here. Do you have one?
