Archimedes’ Lever for the World of Food: \The Overall Nutritional Quality Index (ONQI) David L. Katz, MD, MPH, FACPM, FACP Associate Professor, adjunct, Public Health Practice Director, Prevention Research Center Yale University School of Medicine www.davidkatzmd.com Iowa Dietetic Association Des Moines, Iowa December 4, 2008 The mess we’re in… Adult Population 100% Overweight / Obesity Insulin Resistance Diabetes Mellitus Cardiovascular Disease Time And the mess our children WiLL be in… 100% Overweight / Obesity Insulin Resistance Diabetes Mellitus Time Cardiovascular Disease Writing on the Wall, HOT off the presses- November 12, 2008 Child Obesity Seen as Warning of Heart Disease By PAM BELLUCK NEW ORLEANS — A new study finds striking evidence that children who are obese or have high cholesterol show early warning signs of heart disease. What food can do… 80% reduction in heart disease 90% reduction in diabetes 60% reduction in cancer and so on… Katz DL. Nutrition in Clinical Practice, 2nd Edition. 2008 How to get there from here: Pattern shift: 5 a day, by 3010 and/or Progress, one food choice at a time! but the supply of food for thought is indigestible… Who is even looking out for… things they never knew they never knew? Sodium content per 100 calories? 7 Sodium 73 mg Sodium 100 mg Sodium 233 mg Sodium 131 mg 8 Added sugar per 100kcal? 9 Sugar 12 G Sugar 11 G 10 Nutrition Quiz – Peanut Butter Which of these is more nutritious?

manufacturers For consumers- Consumer Testing Qualitative: focus groups Quantitative: Affinova Group 1: women, n = 454 Group 2: men and women, n = 350 Percent of Respondents Answering “strongly agree” or “agree” (n=454) The system would be useful in helping me make my purchasing decision: 93% The rating system would affect the decisions I make about which foods to purchase in the grocery store: 86% I would be more likely to purchase a product that used the system versus one that did not: 74% I would be more likely to stop at a grocery store that used the system versus one that did not: 66% Consumer Testing: ONQI vs. Alternative (best, better, good, no score) Which store would consumers select if both systems were available nearby? (n = 350) Definitely/Probably ONQI Either Store Definitely/Probably Alternative Neither Store 75% 20% 2% 3% When science means business… it needs to do business One number. One decision. One food at a time. Expert nutritional knowledge in a single score - allowing people to make well-informed choices, one food at a time. NuVal LLC Company Overview NuVal LLC officially formed in March 2008 Originally named ONQI LLC Headquartered in Boston NuVal LLC jointly owned by Topco Associates in Skokie, Illinois Griffin Hospital in Derby, Connecticut and ONQI Science remains the property of Griffin Hospital and is licensed to NuVal LLC Objective of NuVal LLC: Commercialize scores from ONQI Science 42 The NuVal Vision Empowering people to eat better, one well-informed food choice at a time, wherever and whenever food is purchased and consumed.
