Can Color Affect Your Appetite?

Professional chefs understand how important food presentation is for the success of a meal. One element of the eating experience that can be under estimated however, is the effect of color.

Many companies use red in their company logo to draw upon the association of a good appetite with that color with the Coca-Cola emblem as a prime example.

Blue, on the other hand, has been shown to suppress appetite. In a room with blue walls people eat significantly less than those in a neutral environment. One explanation of this effect is there are few naturally occurring blue foods. The instinct then evolved that if food has a blue color it is unfit for consumption. Some birds and lizards make use of this natural aversion by adapting prominent blue coloration to ward off predators.

You may notice that in restaurants with Asian influences these colors will often be found on the walls, table cloth and ornaments. .Within the article on bioflavonoids found on our website,, it is pointed out that foods high in these exceptionally healthful nutrients exhibit these exact colors.
