Nutrition Knowledge Test

How good is your nutrition knowledge?
Can you tell just by looking at a meal whether it is a significant source of protein, fat, or carbohydrates?

Find out for yourself and compare your performance to others!

This test typically takes 10 minutes to complete.

 

This study is being conducted by the Intelligent Interactive Systems Group at Harvard University.

Instructions

You will be presented with pairs of photographs of meals. For each, we will ask you a nutrition-related question like this:

example of a question you will be asked in this test

Please pay attention to the description below each image. It is often hard to see all the ingredients in the photograph. The descriptions will help you figure out what the main ingredients of the meal are.

Your job is to answer the questions as accurately as possible. For some of them (but not all), we will give you immediate feedback on your answer. At the end of the study, we will tell you how well you did and how your score compared to others.

 

The Meal Assistant

Sometimes, you will see a recommendation from a Meal Assistant, which is an experimental computer system that can analyze the nutritional content of meals. The Meal Assistant is right most of the time but not always. You are welcome to consider its recommendations, but you should make whatever decision you think is best.
