The principles of healthy nutrition are represented in the food rainbow. Each of the rainbow colors represents several food groups and the recommended frequency of consumption:

  • The green rainbow - foods that should be consumed in every meal.
  • The yellow rainbow - at least once a day.
  • The orange rainbow - several times a week.
  • The pink rainbow - seldom.
  • The red rainbow - foods we recommend to avoid or consume as little as possible.

Rainbow – the four dimensions of a healthy diet

Health value - preventing diseases by adopting healthy eating habits.

Social value - strengthening family and social ties through eating and cooking at home.

Environmental value - consuming local food and preferring plant food to animal food is also friendlier to the environment, consuming less energy and resources (water, landscape, food transportation, etc.).

Economic value - helps in saving food expenses and strengthening local agriculture.
