Welcome to NAT Version 2.0

NAT is provided as a public service by the Food Science and Human Nutrition Department at the University of Illinois. The tool is intended to empower individuals to select a nutrient dense diet. It is not intended to replace the advice of a physician or health professional.

The database used by NAT is composed of the USDA Handbook #8 and information from food companies. The data should not be taken as an exact representation of the nutrient content of your diet. The numbers used for analysis are averages and there is great variance in nutrient content for each food item in the database. The nutrient information is also not complete for every food listed in NAT as there are still gaps in our knowledge of food composition.

With these limitations in mind, I believe that the tool can provide valuable information on the relative composition of food and I hope this tool will aid you in your quest to achieve or maintain good health via nutritious eating.
