Both a hundred years ago and now, people have strong food preferences. Some people are pickier eaters than others, but almost everyone has a least a few foods they detest. The reasons for why some foods are disliked are many and varied. Cultural factors may affect food preferences. Sometimes a person develops a strong dislike for a food that they once got sick from. Occasionally foods actually taste different to different people because of genetic differences. For example, cilantro tastes “soapy” to people with a certain gene. Here is advice in a 1920 textbook to students in cooking classes about how to move past food prejudices:
Most people have decided likes and dislikes for certain foods. These opinions very often have no reasonable foundation. One taste of a food poorly prepared or a disparaging remark heard in childhood may be the cause for a lifetime’s aversion for a food.
There is no better way to overcome food prejudices than by learning to prepare foods well – to make them tasty and nutritious – and to appreciate their nutritive value. Food prejudices like most others may be overcome by a thorough knowledge of the subject.
Come to the school kitchen with an open mind. When you understand why certain foods are valuable in diet and are able to prepare them skillfully, you may learn to enjoy them. To discover that foods which you previously considered commonplace and uninteresting are tasty, is really a pleasing experience.
