Dr. Brian Wansink, director of Cornell’s Food and Brand Lab has been studying eating behavior and food psychology for decades. Through his extensive research, he has found three key methods for nudging healthy choices at home, in grocery stores, in restaurants and in schools. It’s called “The CAN Approach![1]”  CAN is an acronym for Convent, Attractive, and Normal. Numerous Food and Brand Lab studies have found that making healthy food more convenient, attractive, and normal to eat, results in higher consumption of healthy foods and lower consumption of unhealthy foods.

Below are some ways that this approach can be applied to school lunch lines to increase selection and consumption of the National School Lunch Program meal components (healthy entrees, fruit, veggies and white milk).[2]

Healthy Entrees

Convenient

 

Attractive

  • Highlight entrée options on an attractive menu board
  • Give entrees enticing, descriptive names (see the video).

 ​

Normal

  • Make the healthiest entrée option the “featured entrée” of the day
  • Create combo meals that pair entrees with healthy sides

Fruits and Veggies

Convenient:

Attractive

  • Label fruit and vegetable dishes with creative, age appropriate names. Here are some ideas from the Smarter Lunchrooms Movement: Give Vegetables Creative Names.
  • Display whole fruit in baskets or attractive bowls instead of chafing dishes

Normal

  • Use self-serve utensils that hold the appropriate portion size (larger for veggies and smaller for dressings)
  • Pre-plate trays with the featured vegetable side 

Beverages

Convenient

  • Stock white milk in front of sugary beverages 
  • Make white milk the easiest to reach

Attractive

  • Brand white milk with fun stickers

Normal

  • Fill all coolers with at least 1/3 white milk
  • Keep coolers replenished so they always appear full
