Study Notes
USDA Guidelines for a Healthy Diet
- The USDA provides guidelines for a healthy diet.
- ChooseMyPlate.gov is a resource for dietary recommendations.
Past and Present U.S. Food Recommendations
- Current guidelines address chronic diseases like diabetes.
- Overt nutritional deficiencies are less common.
- Dietary intake recommendations are influenced by personal preferences and other external factors.
Food Choices Today
- Nutrition recommendations are designed for populations and target individuals' nutrient needs.
- People don't always follow dietary recommendations or understand the implementation.
- Individual choices are primarily influenced by taste, cost, and marketing instead of health impact.
What is Nutritional Status?
- Nutritional status is the health influenced by nutrient intake.
- Doctors and dieticians assess nutritional status, including food and nutrient intake, health, and lifestyle.
- Nutritional status assesments are used to distinguish between nourished/malnourished/at risk of malnutrition.
Assessing Nutritional Status
- Step 1: Determine typical food intake. This involves a food diary.
- Step 2: Analyze nutrient intake. Assess nutrient intakes against Dietary Reference Intakes (DRIs). Examples are provided in the slides.
- Step 3: Evaluate physical health. Physical health evaluations should be done.
- Step 4: Consider medical history and lifestyle. A family medical history can provide insight to assist in the assessment.
- Step 5 (if necessary): Assess with laboratory tests. Laboratory results can provide additional information.
NHANES
- National Health and Nutrition Examination Survey provides population-wide nutritional data.
- The survey gathers data on various demographics and demographics like young women, preschoolers, and elders.
- NHANES data supports government recommendations and policies.
Nutrient Descriptors
- (No detailed information provided)
Dietary Reference Intake (DRI)
- DRI is an umbrella term encompassing several nutrient classifications.
- This includes Recommended Dietary Allowance (RDA), Estimated Average Requirement (EAR), Adequate Intake (AI), and Upper Level (UL).
Estimated Average Requirements (EARs)
- EARs represent the average nutrient intake needed by half of the population within a specified gender and age group.
Recommended Dietary Allowance (RDA)
- RDA sets average daily intake levels suitable for 97% of a healthy population, including different age stages and genders.
- The RDA is derived from the EAR and accounts for the majority of the population.
Adequate Intakes (Als)
- Als are established when an EAR and RDA don't exist for a specific nutrient.
- These estimations are based on average intake among healthy individuals.
Tolerable Upper Intake Levels (ULs)
- ULs are the maximum daily intakes of a nutrient that are unlikely to cause health risks.
- These intakes are used to cautiously consider nutrient intake, especially considering supplements and fortified foods.
EAR Vs. RDA Vs. AI Vs. UL
- EAR represents 50% of healthy intakes.
- RDA is the goal intake for individuals, derived from the EAR.
- AI is the intake estimate when RDA data is not sufficient.
- ULs are for caution in excess nutrient intake.
Daily Value (DV)
- DV combines RDA and Daily Reference Values (DRVs).
- DRVs include nutrients not in RDAs.
- DV is used on nutrition labels to indicate content in relation to daily requirements.
Estimated Energy Requirements (EERs)
- EERs estimate average energy intake needed.
- Calculations account for age, gender, height, weight, and physical activity.
- Results are presented as caloric values.
Acceptable Macronutrient Distribution Ranges (AMDRs)
- AMDRs are recommended ranges for protein, carbohydrates, and fat intake.
- These ranges help decrease disease risks.
5 Variables that Affect Your Energy Needs
- Age slows metabolism, requiring less energy
- Gender (males have higher requirements for muscle mass)
- Height leads to higher needs
- Weight leads to higher needs
- Activity levels correlate with higher energy needs.
Where Can We Find Current Dietary Intake Recommendations?
- Dietary Reference Intakes (DRIs)
- USDA Food Guide
- MyPlate Guidelines
- Dietary Guidelines for Americans
Tools for Diet Planning
- DRIs are not practical for most.
- Dietary Guidelines, and resources like MyPlate, help patients plan diets.
Dietary Guidelines for Americans (2020-2025)
- Diet and lifestyle recommendations for health, overweight, and chronic disease prevention.
- Evidence-based, age-specific guidelines.
- Updated every 5 years to reflect changes and data.
Dietary Guidelines for Americans (2020-2025) Specific Recommendations
- Healthy dietary patterns at all life stages.
- Nutrient-dense foods, reflecting personal preferences and needs.
- Calorie consumption in moderation.
- Limiting certain nutrients (added sugars, saturated fat, sodium, and alcohol).
- Emphasizing specific food groups like vegetables, fruits, whole grains, dairy, protein, and fats.
MyPlate
- Based on USDA Dietary Guidelines.
- Illustrates the proportion of five food groups (fruits, vegetables, grains, protein, and dairy),
- Emphasizes proportionality, variety, and moderation in portion sizes.
- Provides a visual index for planning diets.
MyPlate Food Groups
- Provides guidelines for portion sizes of different food groups.
MyPlate: What Counts as an Ounce or a Cup?
- Food standards for common food groups.
- Portion descriptions are provided.
MyPlate Daily Food Plan: Example
- Example daily meal plans designed to meet nutritional guidelines.
- (Detailed plan, so it's best to read the slide itself)
Empty and Discretionary Calories
- Empty calories come from solid fats and added sugars.
- Discretionary calories are the remaining calories after essential nutrient needs.
- Important to consider these calories for health and well-being and consume in moderation.
Discretionary Calories
- Illustrates caloric breakdowns, with a visual.
What Should We Eat?
- Maintain weight by balancing calories.
- Include healthy foods, nutrients, with short ingredient lists to support health.
Exchange Lists
- Foods are categorized by carbohydrate, fat, and protein content for calorie control.
- Exchange lists can help diabetics and others manage calorie intake.
Health vs. Qualified Health Claims
- Explains "authorized" (FDA-supported) and "qualified" (emerging, yet not conclusive) health claims.
Structure/Function Claims
- Describe nutrient roles in maintaining normal bodily function.
- Do not require FDA approval for general use on food labels, but they do require FDA approval on dietary supplement labels.
Health vs. Structure/Function Claims
- Explains the difference between health and structure/function claims.
- Health claims are specific and validated by the FDA, while structure/function claims describe the effects of nutrients on bodily functions.
