What you think of this program is very important to us. Please send us all your questions, whether they are nutrition questions or questions about the Nutrition Analysis Tool.

NAT uses extensive use of tables. NAT can be used with most browsers that do not support tables but the visual results may not be what was intended.

Note to Users:

Please be aware that due to heavy usage, there is a certain lag time before the NAT scripts can return computed information back to you and your browser. We are experiencing even greater loads on the server because some users do not seem to realize this and are sending the same request to NAT over and over again. Please refrain from hitting a submit button more than once (the server only goes slower the more you hit the button.) Thanks!
