It doesn't look like much. But toddlers are small and they are not growing too quickly. They only accept a few foods. Obviously children are capable of learning to like and accept a wide variety of foods. Rest assured, that Mexican child would probably find the idea of macaroni and cheese disgusting.
Kids learn to accept foods in a social and cultural context.
Impacting that acceptance are some inherent characteristics of toddlers. Research has shown that a couple of factors are primary determinants of a child's preference for food. Not surprisingly, one is an unlearned liking for sweet taste. The second determinant is familiarity . Familiarity is unrelated to any characteristic about that food, such as smell or taste or texture.
