Color and Appetite Relationship

Plates4   Blue Color in Food

The above food has added blue colors (Plate4) that may affect the appetite. Blue food is not commonly found in nature. Rarely we find blue vegetables and fruits (berry), no blue meats (blue-burger, well-done please), and a few blue-purple potatoes from remote spots on the globe. It is not are to have such food. Ancient period blue color in food signified poisonous. People would naturally avoid take blue color food.

Mr. Gary Blumenthal, a food professional explains the relationship between food color and appetite, “Color and the appeal of various foods are also closely related. Just the sight of food fires neurons in the hypothalamus. Subjects presented food to eat in the dark reported a critically missing element for enjoying any cuisine: the appearance of food. For the sighted, the eyes are the first place that must be convinced before a food is even tried. This means that some food products fail in the marketplace not because of bad taste, texture, or smell but because the consumer never got that far. Colors are significant and almost universally it is difficult to get a consumer to try a blue-colored food -- though more are being marketed for children these days. Greens, browns, reds, and several other colors are more generally acceptable, though they can vary by culture. The Japanese are renowned for their elaborate use of food colourings, some that would have difficulty getting approval by the Food and Drug Administration in the United States.” International Food Strategies
