Taste Aversion-With taste aversion, the mind develops a resistance towards a certain food. In simpler terms, eating certain types of food can cause a bad reaction. This is a form of classical condition when the body uses a natural instinct as a means of protection. This is also called a survival mechanism. It warns the body if a type of food (berries or mushrooms) is harmful.
A person can acquire a taste aversion to a type of food, due to circumstances, as well. For example, an individual may eat lasagna at an early age and become sick. The sickness may be caused by any reason-(bad tomato in the sauce or the meat not thoroughly cooked). Regardless of the reason, that individual may have a negative reaction to eating lasagna any given time after the experience.
