Taste Aversion
Taste aversion is when someone has an aversion to a certain food or taste, because the person became nauseous or sick after eating that food once before. They associate being sick with the taste of that food, and no longer want to eat that food. The sickness is sometimes not even the result of the food, but humans make this association anyway. As humans, we are inclined to have aversions to foods that make us sick after eating or tasting them, therefore taste aversions are common.
When I was younger, my oldest brother ate hamburger helper one night for dinner. Later that night he drank a chocolate milkshake, and shortly after, he threw up outside of our house on our porch. Ever since that night, he refuses to eat hamburger helper, because he believes that is what made him vomit that night. My brother has a taste aversion to hamburger helper, because he associates it with getting sick to his stomach. Numerous times my mom tried to tell him that the hamburger helper did not make him sick, especially since no one else in the family had the same reaction to it as he did, but he could not get rid of the aversion.
An own personal experience with taste aversions, happened to me last year right before spring semester ended when my mom sent up homemade chocolate chip cookies for finals week. Right around the time she sent them up to me, I contracted strep throat, so I now associate a very sore throat with her chocolate chip cookies. I have a taste aversion to these chocolate chip cookies, and whenever she makes them, I do not have an urge to eat them. If I just take one bite of one, the taste automatically reminds me of the week last year when my throat was so incredibly sore, and I was in constant pain. Even though, I know the chocolate chip cookies were not the cause of my strep throat, I cannot help but relate the two together.
Many people have taste aversions, since as humans we relate the taste and sickness together. This can actually be a good thing sometimes. If the food was the real source of the sickness, not eating the food again is a smart decision. However, most times, the food is not the actual cause of the sickness.
