Study Notes

Chapter 2: Standards for Nutrient Intake

Chapter 2 outlines early dietary standards and recommendations, standards (RDA, DRIs), diet quality (Dietary Guidelines, MyPlate, indices), and tools using standards (nutrition labeling, label claims).

Early Dietary Standards and Recommendations

Historical timeline of nutrition recommendations shows a shift from concerns about nutrient inadequacy to concerns about excess and chronic disease.
Early examples include British Merchant Seaman's Act, observatinal standards, USDA standards (energy, protein, calcium, phosphorus, iron, vitamins A&C) and 1st RDA by FNB.

Standards

Recommended Dietary Allowances (RDAs): Established in 1941 by the Food and Nutrition Board to ensure adequate nutrition, primarily focusing on deficiency diseases. RDAs did not address chronic diseases, carbohydrate, dietary fiber, fats or cholesterol, nor the use of supplements.
Dietary Reference Intakes (DRIs): A comprehensive set of nutrient standards developed by the Institute of Medicine (IOM). These are widely used and include reference values for nutrients needs, amounts to prevent deficiency diseases, amounts to reduce risk of chronic diseases and upper levels of safety for nutrients.

Diet Quality

Dietary Guidelines and MyPlate: Aimed at improving overall diet quality and health, supporting nation-level and international policies to improve public health.
Indices of Diet Quality: Methods to assess and evaluate dietary quality across different populations and groups.

Tools Using Standards

Nutrition Labeling: Allows consumers to understand the nutrient content of food products.
Label Claims: Important for consumers in making informed decisions about food products, allowing them to understand nutrient content in food products.

Dietary Reference Intakes (DRIs)

A comprehensive set of nutritional and dietary standards for healthy people, providing values for different life stages.
- Released in August 1997 (calcium, phosphorus, magnesium, fluoride)
- Remaining vitamins and elements as well as electrolytes, water, energy, physical activity, dietary fiber, and macronutrients have been updated.
- Latest updates include Calcium and Vitamin D in 2011, and Sodium and Potassium in 2019.
Provide nutrients standards for requirements and excessive levels of nutrients.
Recommendations include protein, fats, carbohydrates, vitamins, minerals, water, and calories and physical activity.
Promoting good health through nutrition monitoring, dietary guidelines, assistance programs, food policies, military needs, nutrition labeling, and global nutrient standards.

Important components of the DRIs.

Estimated Average Requirement (EAR): Average daily nutrient intake level estimated to meet the needs of 50% healthy people. Values used to calculate the RDA.
Recommended Dietary Allowance (RDA): Average daily nutrient intake level believed to meet the needs of 97-98% healthy people.
Adequate Intake (AI): Used when scientific data are insufficient for establishing an EAR or RDA, and it signifies the recommended average daily intake when insufficient evidence exists to establish an RDA or EAR.
Tolerable Upper Intake Level (UL): Highest average daily intake level not likely to pose risk of adverse health effects.

Estimated Energy Requirement (EER)

Average energy intake to maintain energy balance. -Based on doubly labeled water studies. -Tailored to age, height, weight, and activity levels. -Includes growth needs in children. -Includes needs for tissue accretion and milk secretion in pregnant and lactating women.

Acceptable Macronutrient Distribution Range (AMDR)

Percent range of total daily energy intake for each macronutrient.
Associated with reduced risk of chronic disease and adequate nutritional levels.
- Values for specific age groups (children 1-3 y, 4-18 y, and adults) are provided for fat, n-6 (linoleic acid) and n-3 polyunsaturated (alpha-linolenic acid) fatty acids, carbohydrates, and protein.

Using DRIs

Used to assess nutrient intake and plan for nutritional needs.
- Intake values that are greater than or equal to the RDA are considered adequate for the population.
- Values significantly lower than EAR are considered inadequate.
