EPHE 155 Spring 2025 Nutrition Standards & Guidelines PDF

Summary

This document provides an introduction to nutrition concepts and controversies, along with standards and guidelines. It details learning goals regarding dietary reference intakes (DRI), recommended intake values, safety guidelines and a discussion on preventing chronic diseases. It also explains the importance of the DRI committee's role in facilitating nutrition research and policy, alongside a summary table for various nutrition standards and recommendations.

Above this level risk could increase and it may also be well tolerated Nutrient Standard cont. DRI cont. CDRR Chronic Disease Risk Reduction New DRI AMDR Acceptable Macronutrient Distribution Range Food labels DV Daily Value %DV The % of the DV that a food delivers RDI Recommended Daily Intake Energy Needs EER Estimated Energy Requirement Understanding the DRI Values are based on probability and risk Targets are based on meeting the need, on average, day over day Differ from group to group: men, women, children … Not minimum requirements Established to prevent development of deficiency states and of chronic diseases. Apply to healthy people Understanding the DRI Specific indicators of nutrient adequacy: Blood nutrient concentrations Normal growth Reduction of certain chronic diseases A person may require a much higher or possibly lower intake of certain nutrients during the stress of illness or malnutrition RDA values are set to cover the needs of 97-98% of the healthy population and not set so high to be excessive. RDA values Based on observed or experimental approximates, when RDA cannot be determined AI values Set to cover the average needs of a person eating 2000 Calories each day. Used for food labelling. DV Carbohydrate Intake Targets Total Carbohydrate: AMDR is 45-65% as % of calories Acceptable Macronutrient Distribution Range (AMDR) RDA is 130g minimum Working target is 5-12g/kg AI for Fibre: Women age 19-50: 25g Women age 51+: 21g Men age 19-50: 38g Men age 51+ 30g WHO 25g Added sugar Less that 10% of daily calories Lipid Intake Targets Total Fat: AMDR is 20-35% as % of calories Saturated Fat: DRI Keep to less than 10% of Calories Trans Fat: WHO: less than 1% of total calories Cholesterol: DRI: the consumption of saturated fat, trans fat and cholesterol should be as low as possible PUFA the EFAs: Linoleic Acid (5-10% of total Calories) 17g per day for young men 12g per day for young women Linolenic Acid (0.6-1.2% of total Calories) 1.6g per day for men 1.2g per day for women Protein Intake Targets AMDR is 10-35% as percentage of calories RDA is 0.8g/kg (I use 0.8-2g/kg) The amount needed depends on body size, stage of development, and circumstances. 1942 and 1944 a time of food rationing and poverty The Canada Food Guide released Jan 2019 … page 2 Understanding Daily Value (DV) -used on Food Labels DRI values vary from group to group but on a food label, we need one set of values that must apply to everyone The DV reflects the needs of an “average” person DV is based on a 2,000-Calorie per day intake Understanding Daily Value (DV) DV are ideal for allowing comparison among prepackaged foods The %DV shows whether the food has a “lot” or a “little” of a nutrient in a stated amount of food Because the DV apply to all people, they are much less useful as nutrient intake goals for individuals Ingredient List Claims on Food Labels Nutrient Function Claims: Outlines a role that a nutrient may have in our biological systems. Health Claim: Links food constituents with disease states, Nutrient Content Descriptor: Describes the nutrient value in a good. i.e. high or low in … ** these all have to be carefully worded and meet Health Canada standards Sodium, Sugar, and Saturated Fat Mandated June 2022 and required by January 2026 Assignment 2
