It takes 6 weeks to develop a new habit.


Helaine Ciporen: You are the Principal Inventor of NuVal, a remarkable system of scoring foods from 1 to 100 based on their nutritional value.  How did you come up with that idea?

Dr. David Katz: Well, NuVal was inspired by many things, but probably foremost among them, my own family. My wife, who has a Ph.D., five kids and a nutritionist husband, would come from the supermarket with four loaves of bread and smoke coming out of her ears and say, “If you want the most nutritious one of these you can figure out which one it is! Bread A is the one with the most fiber, but also the most sodium; bread B has less sodium, but it has added sugar; bread C says zero grams trans fat on the front of the package, but it’s the one with partially hydrogenated oil; and bread D is a multigrain, but it has the least fiber of all.”  Once people have the will to get to better nutrition we certainly ought to give them the way. My idea was essentially a GPS system for nutrition. (Click here for complete interview)
