NUTRITION RECOMMENDATIONS
Obesity and Diabetes Trends:
What is happening? People are getting more obese
Why? More food out there per person, food companies want you to eat more, less exercise, total caloric sweeteners, price of healthy foods went up, portion sizes rising
What is a better way to characterize the “epidemic”
1. The physical inactivity epidemic
2. Poor nutrition epidemic
Nutrition Recommendations
Overview: 1. Dietary Reference Intakes (Food and Nutrition Board, National Academy of Sciences) 2. Food Labels (FDA) 3. Dietary Guidelines for Americans (USDA/HHS) 4. myplate.gov (USDA/HHS) 5. Other Food Pyramids (Harvard, U of M)
1. Dietary Reference Intakes A. Set by the Food and Nutrition Board, National Academy of Sciences, Washington DC 1. Nutrition and Food Scientists B. Most recent DRI’s: 1997-2010 C. Goals of DRI's (4): 1. Setting recommended intake values • Recommended dietary allowances (RDA) • Adequate intakes (Al) 2. Facilitating nutrition research and policy • Estimated Average Requirements (EAR) 3. Establishing safety guidelines • Upper intake levels (UL) 4. Preventing chronic disease D. Recommended Dietary Allowances (RDA): 1. Nutrient intake goals for individuals E. Adequate Intakes (AI): 1. Nutrient intake goals for individuals 2. Set when scientific date are insuffiencent to establish RDA F. Estimated Average Requirements (EAR): 1. Population-wide average nutrient requirements use in nutrition research and policymaking 2. Form the basis for the RDAs G. Upper Intake Levels (UL): 1. Suggested upper limit for potentially toxic nutrients 2. Intakes above the UL are likely to cause illness from toxicity H. How does the DRI committee establish DRI values? 1. Acceptable macronutrient distribution ranges (AMIDR) for energy
