Dietary Tools Flashcards
tools devised to aid in planning, procuring, preparing, serving & consuming meals for both normal & therapeutic diets of individuals or groups .
dietary guides
Qualitative and quantitative translations of the recommended allowances for specific nutrients.
food guides
These guides provide proper food choices with suggested amounts and often also dispense tips on how to plan, select and prepare adequate meals for the family.
food guides
Classification of dietary tools
Qualitative and Quantitative
Translate quantitative nutritional requirements into simple, practical and non-technical language
Qualitative dieatry tools
Includes dietary reference intakes, tables containing the chemical composition of food, and similar materials or tools
quantitative dietary tools
4 examples of Qualitative Dietary Tools
- Your Guide to Good Nutrition
- Pinggang Pinoy
- The Food Pyramid
- Nutritional Guidelines for Filipinos
Dietary principles illustrated by the Qualitative guides
- Variety
- Balance
- Moderation
Providing foods of a number of types in proportion to each other, such that foods rich in some nutrients do not crowd out the foods that are rich in other nutrients
Balance
Eating a wide selection of foods within and among the major food groups
Variety
In relation to dietary intake, providing enough but not too much of a substance
Moderation
Other principles related to diet planning
Adequacy, energy balance, nutrient density
Diet provides sufficient energy & nutrients to meet the health needs of healthy people
adequacy
This is achieved when energy (kcal) intake is equivalent to kcal output. This is the key of weight management.
energy balance
Foods that deliver the most nutrients for the least food energy
Nutrient density
Dietary tool that is also known as the three food groups
Your Guide to Good Nutrition
Dietary tool where foods are grouped based on physiological functions which are energy giving, body building and body process regulating together with recommended amounts
YGGN
Practical translation of the Philippine Dietary Recommended Intake (PDRI)
PDRI
The 3 food groups of YGGN
Energy-giving
- rice and other cereals, starches, sugars and fat
Regulating
- fruits and vegetables which provide vitamins and minerals
Body building
- foods which supply good protein, some vitamins and minerals
Also known as the plate model
Pinggang Pinoy
Promoted in 1987 by the Swedish Diabetic Association and the Community Nutrition Group of the British Dietetic Association
The Plate Model
Simple qualitative visual model of promoting healthful eating
The Plate Model
Uses a dinner plate as a graphical representation of a pie chart
The Plate Model
Components of The Plate Model
1/2 plate vegetable
1/4 plate starchy foods
1/4 plate meat and alternatives
on the side: fruit, milk, or yogurt
A simple and easy to follow daily eating guide for Filipinos
Food pyramid
Based on the usual dietary pattern of Filipinos in general
Food Pyramid
T or F: The Food Pyramid ranks food groups according to the amounts to be consumed from the most (base) to the least (tip)
T
Different Levels of the Food Pyramid
Level: Base –
Nutrients: Water –
Food: Beverages, Soups
Level: 2nd –
Nutrients: Starch, fiber, vitamins and minerals –
Food: Breads, Cereals, Rice, Pasta
Level: 3rd –
Nutrients: Vitamins, minerals (A, C, K) –
Food: Fruits, vegetables
Level: 4th –
Nutrients: Proteins, vitamins, minerals –
Food: Animal proteins, dried beans, nuts, milk and dairy products
Level: 5th –
Nutrients: Sugar, Fats
Primary recommendations to promote good health through proper nutrition
Nutritional Guidelines for Filipinos
Aim to encourage the consumption of an adequate and well-balanced diet
Nutritional Guidelines for Filipinos
May be revised from time to time as the need arises & adapted to a country’s lifestyle, culture, and resources
Nutritional Guidelines for Filipinos
Simple statements that give advice on the consumption of foods and food components for which there are public health concerns
Nutritional Guidelines for Filipinos
Purpose of the nutritional guidelines
- Provide the general public with recommendations about proper diet and wholesome practices to promote good health for themselves and their family
- Provide those concerned with nutrition information education with a handy reference for their counseling and educational services
What’s new in the 2012 Nutritional Guidelines for Filipinos
The 2012 NGF now includes the basis and justification for each of the ten nutritional and health message.
The 10 statements in the Nutritional Guidelines for Filipinos
- Eat a variety of foods everyday to get the nutrients needed by the body.
- Breastfeed infants exclusively from birth up to six months, then give appropriate complementary foods while continuing breastfeeding for two years and beyond for optimum growth and development.
- Attain normal body weight through proper diet and moderate physical activity to maintain good health and prevent obesity.
- Consume fish, lean meat, poultry, egg, dried beans or nuts daily for growth and repair of body tissues.
- Eat more vegetables and fruits everyday to get the essential vitamins, minerals and fiber for regulation of body processes.
- Limit intake of salty, fried, fatty and sugar-rich foods to prevent cardiovascular diseases
- Consume milk, milk products, and other calcium-rich foods, such as small fish and shellfish, everyday for healthy bones and teeth.
- Use iodized salt to prevent Iodine Deficiency Disorders.
- Consume safe foods and water to prevent diarrhea and other food- and water-borne diseases.
- Be physically active, make healthy food choices, manage stress, avoid alcoholic beverages and do not smoke to help prevent lifestyle-related non-communicable diseases.
Dietary tools expressed in terms of food types
Qualitative Dietary Tools
Dietary tools expressed in terms of nutrient levels
Quantitative Dietary Tools
4 Quantitative Dietary Tools
- Food Composition Tables
- Philippine Dietary Reference Intakes
- Food Exchange Lists
- Nutrition Labels
A dietary tool that contains numerical values indicating the total amount of the constituents in foods.
FCT
These constituents are considered bioavailable NOT the amount absorbed
FCT
Broadly defined, it refers to the proportion of a nutrient that can absorbed from the diet and used for normal body functions.
Bioavailability
The metabolic pathways where changes in bioavailability may occur
- release of the nutrient from the physicochemical dietary matrix
- effects of digestive enzymes in the intestine
- binding and uptake by the intestinal mucosa
- transfer across the gut wall (passing through the cells, in-between them or both) to the blood or lymphatic circulation
- systemic distribution of the nutrients in the body
- Systemic deposition in the body (like fat stores or vitamin A reserves)
- metabolic and functional use of the nutrient
- Excretion through urine or feces
Factors that may affect nutrient boiavailability
- Chemical form or gradient
- Nature of the food digested
- Composition of the total diet
- Level of nutrient stores
- Physiological status of the individual
- Socio-cultural environment
Used to calculate the nutrient intakes of individuals or groups provided quantitative methods have been used to collect the food consumption data.
FCT
Gaps in the local analytical data are filled by using values from other food composition tables
FCT
Sources of Discrepancies between analyzed and calculated nutrient contents arising from food preparation:
- Variable fat content of the meat and made-up dishes
- Differences in water or moisture content
- Trace metal contamination from knives, pots, pans, & bowls.
- Variability in the salt content of processed and home prepared foods
- Large range losses of heat labile & water-soluble vitamins during food preparation
Sources of error in FCTs
- Inadequate sampling protocol for the food items to be analyzed
- Use of inappropriate analytical methods for the analysis of a nutrient
- Lack of standardized conversion factors for calculating energy and protein content of foods
- Inconsistencies in terminology used to express certain nutrients
- Incorrect description of individual food item and/or nutrient values
- Inconsistency resulting from genetic, environment, food preparation, and processing factors
