Why does food taste great or nasty? Have you ever looked at something and automatically decide that it's not nasty without tasting it? That because taste involves more than what we place on our tongue. It involves our nose, eyes, ears and skin. According to Lawrence D. Rosenblum, we taste what we see, hear, touch, smell, expect and understand. 80% of what we taste comes from smell. If I bring you a plate of food and it smells sour, you won't eat even if I tell you that its your favorite food. According to synesthesia. Sage says, "Those in the food research field have co-opted this definition to mean more of a general multi-modal experience, where the stimulation of one sense causes a perception in a different sense". After reading our book by Rosenblum and the article by Sage, I now know why I absolutely hate avocado. I hate the look of it and the texture when I touch it. It's reminiscent of baby poop.
