Summary
This document discusses dietary reference intakes and nutrient recommendations. It covers topics such as assessing individual nutrient intake levels, making recommendations on consumption, and the collaboration between NIH and Health Canada. The document identifies specific goals of the DRI committees, including setting recommended intake values, facilitating nutrition research, establishing safety guidelines, and preventing chronic diseases. It further elaborates on notable concepts like tolerable upper intake levels (UL), chronic disease risk reduction (CDRR), and acceptable macronutrient distribution ranges (AMDR).

Dietary Reference Intakes Introduction to Human Nutrition Faculty of Science | Department of Biochemistry Dietary Reference Intakes and Nutrient Recommendations Sets of values used to: 1. Assess an individual’s energy or nutrient intake level (e.g. too much or too little?). 2. Make recommendations or give advice on how much should be consumed. 3. Devised as a collaboration between the NIH (USA) and Health Canada – ongoing process. Faculty of Science | Department of Biochemistry Dietary Reference Intakes DRI committee has set recommended intakes for: Vitamins Minerals Carbohydrates Fibre Lipid Protein Water Energy Faculty of Science | Department of Biochemistry Goals of the DRI Committees Goal #1: Setting Recommended Intake Values 1. RDA: Based on solid experimental evidence and reliable observations 2. AI: Scientifically based, but requires some educated guesses Faculty of Science | Department of Biochemistry Goals of the DRI Committees Goal #2: Facilitating Nutrition Research and Policy 1. EAR: Nutrient requirements for given life stages/gender groups used by researchers and nutrition policymakers Goal #3: Establishing Safety Guidelines 1. UL: Identifying potentially hazardous levels of nutrient intake; used to set safe upper limits for food/water supply Faculty of Science | Department of Biochemistry Goals of the DRI Committees Goal #4: Preventing Chronic Diseases 1. Acceptable Macronutrient Distribution Range (AMDR): A diet with these proportions** can provide adequate nutrients and reduce risk of chronic diseases 45%-65% from carbohydrates 20%-35% from fat 10%-35% from protein **Expressed as the % of daily caloric intake Faculty of Science | Department of Biochemistry Dietary Reference Intakes Faculty of Science | Department of Biochemistry Dietary Reference Intakes Faculty of Science | Department of Biochemistry The size of each “window” varies by nutrient Will be influenced by stage of life May be influenced by health status Faculty of Science | Department of Biochemistry Faculty of Science | Department of Biochemistry Faculty of Science | Department of Biochemistry The Exception: Energy Recommended Intakes of Nutrients versus Energy Faculty of Science | Department of Biochemistry RDA and AI vs EAR Faculty of Science | Department of Biochemistry What are your nutrient requirements? Go look up your own specific nutrient requirements using the tables in the front of the textbook or the tables posted from Health Canada on the supplementary information page on Brightspace.
