French fries taste different on a blue plate Health and science

Where does this news come from?

We all know picky eaters in our area. For example, if someone dislikes fruits and/or vegetables, that is possible. be harmful to health. After all, fruits and vegetables are essential components of a healthy, balanced diet.

British scientists investigated whether the color of a plate can influence eating behavior (1):

  • They divided a group of 47 participants through questionnaires picky and easy eaters.
  • Subsequently, the participants received 25 grams French fries in 3 plates with different colors: blue, red and white.
  • The participants had to indicate how salty and how attractive they found the fries:
    • For easy eaters, the color of the plate made no difference.
    • He picky eaters found:
      • the chips on a blue or red plate saltier then that of a white plate;
      • the french fries on a most attractive blue plate than those of a red or white board.

The researchers concluded that people tend to eat more than one blue plate.

How should you interpret this news?

This study suggests that the color of a plate may encourage picky eaters to eat more. But this study can’t really prove that the color of a plate can positively influence your eating behavior. It has several limitations:

  • the study was not blind: participants knew what dish they ate from.
    • That can affect the results.
  • French fries are not a suitable product. to find out if a certain colored dish makes someone eat healthier.
    • The same test with sprouts would have been more interesting.
  • That number of participants they were in the studio too small.
    • Therefore, the observed differences may be due to chance.
  • A fun thought: The researchers didn’t check to see if the participants were color blind.
    • This can affect how they perceive the colors of the plates.
    • For example, most people who are color blind cannot distinguish red from green. A red signal that turns green is probably less attractive.
  • The picky eater category seems rather contrived: what constitutes being a picky eater is not clearly described.
  • eventually there was just a tested food: chips.
    • Not everyone likes to eat French fries, without being a picky eater.

So it’s doubtful that young children will suddenly appreciate sprouts because the color of their plate is different. And that, for example, a Christmas turkey looks tastier on a white or blue plate than on a dark brown plate, it is quite obvious.

It was previously investigated whether the plate size it can influence your eating behavior: you would eat a little less than a small plate.


A small-scale British study found that picky eaters eat more chips from a blue plate than from a red or white plate. Difficult eaters seemed to experience blue plates as more enjoyable. However, the differences were limited. Whether the color of a dish can also make people eat healthier cannot be shown with chips.
