When John Garcia conducted an experiment that paired taste, sight, or sound with radiation, he found that taste was strongly associated with nausea. This led to the concept of taste aversion. As defined in our notes, taste aversion means that humans are apt to have an aversion to foods if they become sick afterwards. In class we mentioned that taste aversion might be a survival instinct that is coded into our genes. This would explain why we have such a violent dislike of something that was paired with our bodies being sick. Our body is just trying to keep us alive and healthy.
I have experienced taste aversion in my own life and it still affects me today. When I was a child and couldn’t take pills, I would have to take liquid medicine. My mom would give me the liquid Tylenol in grape flavor. I can remember the taste and the disgustingly thick texture to this day. Because I would take this when I was sick with a fever, that often meant that it accompanied throwing up. Ever since I was forced to take grape flavored Tylenol I have had a taste aversion to anything grape flavored. To this day I will not eat grape popsicles or grape candy and I will not drink anything grape flavored.
My roommate also shared her taste aversion story with me. She once ordered a cheeseburger from McDonald’s. After consuming it, she ended up becoming sick and throwing up. Now she can’t even think about eating a McDonald’s cheeseburger without wanting to throw up. It is interesting how she can eat anything else from McDonald’s besides their hamburgers and cheeseburgers. My own brother even has a taste aversion to grilled cheese because of becoming sick after eating one. I find it fascinating how almost everyone you talk to has their own experience with a food item to which they have developed a taste aversion.
