My entire life I’ve just thought I was a picky eater. People have thought I was crazy for being a vegetarian based on the fact I thought meat tasted bad. People think I’m a weird vegetarian because I don’t like mushrooms. But the majority of the foods I don’t eat fit into this “fifth taste” group. This is a legitimate distaste for these foods not just me being a jerk. Hurrah!
