Conditioning plays a role, including instances where parents urge children to eat specific foods, which can backfire. Children have more sensitive palates and may initially dislike bitter foods and certain textures, but this aversion can lessen with exposure. This is not always the case, but generally speaking. For example, children in Japan eat natto, which is slimy and has a strong smell. Children in India eat spicy curry. These preferences are largely influenced by their environment.
