Q

Estimated Average Requirement (EAR)

A

amount of a nutrient that will meet the needs of 50% of the population
- EAR rarely used alone, mainly to set recommended dietary allowance

Q

Recommended Dietary Allowance (RDA)

A

amount of a nutrient that meets the needs of 97% of the population
- RDA is set two standard deviations, 20–25%, higher than the EAR

Q

Which DRI out of the four is preferred?

A

Recommended Dietary Allowance (RDA) because it determines adequacy
- If we cannot determine EAR, then an RDA cannot be set

Q

Adequate Intake (AI)

A
  • Sometimes, there is not enough scientific data to establish the EAR and RDA, so AI is used
  • determined by observing how much of that nutrient healthy people eat
    More difficult to establish deficiencies since there is less evidence

Q

Tolerable Upper Limit (TUL/UL)

Q

What are the RDA for lipids and carbohydrates?

A

There is no RDA for lipids and carbohydrates, so the AMDR can be used to determine whether intake meets health needs

25
Why should pregnant women choose foods with healthy fats instead of saturated fat
More omega 3 fatty acids required during pregnancy for healthy brain development Ex: nuts, seeds, fatty fish, veggie oils
26
Why should pregnant women choose fish low in mercury?
high levels of mercury can negatively impact brain development of child Ex: minimize large fish like tuna = higher in mercury
27
Why should pregnant women eat a little more food each day than you normally would
Extra need for energy to support growth of child in 2nd/3rd trimesters and to produce breast milk. Too much maternal weight gain can negatively impact child/mother health Ex: small meal/extra snack, banana
28
Why should pregnant women get enough iron
Iron needed for blood and contributes towards baby’s development (iron stores) Ex: tofu, fish, eggs, lean meats, whole grain
29
Why should pregnant women take a daily multivitamin
Micronutrients needs increases during pregnancy and lactation. Consuming enough folic acid reduces risk of birth defects
30
Why should pregnant women be food safe
Higher risk for food poisoning during pregnancy, negatively impact both mother and baby Ex: minimize light cooked eggs, meat, raw seafood like sushi
31
What changes were made to Canadian food policy in 2013
- 2019 Canadian food guide - Lowered sodium content in prepackaged foods - Reasonable sodium targets within food and hospitality industries - Expansion of vitamin D fortification program - Elimination of industrial trans fat from food supply - Changes to food labelling
32
Food labels
communicate information about packaged foods so consumers can make informed decisions
33
What food items don’t require a food label?
- Raw animal products, fresh fruits and vegetables and foods prepared fresh in stores (salads and muffins) - Neither do alcoholic beverages, not considered foods and are regulated under different legal acts.
34
What six mandatory pieces of information that must appear on a Canadian food label
1. common name of the food 2. Net quantity (total weight, volume) 3. Name and address of producer 4. Date marking (best before) with 90 day shelf life 5. 1st ingredient in ingredient list is greatest amount by weight 6. Nutrient facts box (expressed in grams/daily values)
35
Daily values
compares the amount of nutrient in a serving size to an appropriate DRI
36
Daily values
compares the amount of nutrient in a serving size to an appropriate DRI
37
What changes are made to the ingredients list of a product
- Sugar based ingredients are grouped together - Food colours are listed by name
38
What changes are made to the nutrients facts box?
- calories/serving sizes are prominently displayed - % of daily value for sugar - vitamina and are no longer displayed - Potassium is now displayed - exact amounts are shown - Footnote about % daily value
39
Claims on food labels
Food packaging may contain certain claims to highlight a nutrient, health-associated factor or the nature of a food
40
Guidelines for the food claim: “Pure, 100% pure, 100%, all”
Only used for foods that are uncontaminated, must only contain listed product in whole form, not a compound, mixture, imitation or substitute Ex: 100% pure fruit juice, 100% corn oil
41
Guidelines for the food claim: “True, real, genuine”
Cannot contain foods or ingredients that are substitutes or imitations Ex: genuine maple syrup, contains real strawberries
42
Guidelines for the food claim: “ Vegetarian claim”
Must not mislead and must properly represent the type of vegetarian diet Ex: vegan mayonnaise, part of a lacto-ovo vegetarian diet
43
Guidelines for the food claim: “Highlighted ingredient claims”
Only highlight ingredients that are present, those not present cannot be shown in words or pictures, also cannot emphasize the importance of an ingredient or substance Ex: (contains blueberries, has a picture of blueberries on label)
44
Guidelines for the food claim: “Minute or trace ingredients”
Cannot emphasize the presence of a nutrient or substance found in minute amounts Ex: calcium beverage could only be used if there was enough calcium
45
Guidelines for the food claim: “Negative claims”
Cannot mislead and can only be used when the amount of substance is zero or a non-detectable or physiologically insignificant amount Ex: no artificial sweeteners, no preservatives added, lactose free
46
Nutrient content claims
amount of energy or specific nutrient in a food - claim on a package, the product must comply with the requirements for that statement
47
What are examples of nutrient content claims?
low in fat, lower in Calories and high in fibre Ex: low in fat, it must contain 3 g or less of fat per serving and 30% or less of the energy in that product can come from fat
48
What are the two categories of health claims?
disease reduction claims and function claims
49
Disease reduction claims
link a food or its ingredients with a reduced risk of developing a specific disease - a healthy diet, rich, and a variety of vegetables and fruit may help me reduce the risk of some types of cancer
50
Function claims
association between consuming a nutrient or diet factor with its role in the normal bi- ological function of the body Ex: protein - helps build and repair body tissues, help build antibodies
51
Front of package labels
- mandatory front-of-package labelling for foods high in sodium, sugar and saturated fat - associated with an increased risk of disease when consumed in excess
52
Food safety
Foods can carry pathogens (disease-causing agents) which can promote food poisoning
53
Natural Health Products (NHPs)
neither foods nor drugs but are naturally occurring substances used to address health needs Ex: sold vitamins, minerals, multivitamins, probiotics, amino acids and essential fatty acids, as well as homeopathic and traditional medicines
54
Cons of Natural Health Products (NHPs)
- contains incorrect ingredients - stated claims may not fully support by evidence - promotes unwanted side effects like allergic reactions or negative interactions with other NHPs or prescription drugs
55
What must NHP labels include
product name, the net quantity of prod- uct in the container, a complete list of medical and non-medical ingredients, the recommended dose, specific storage conditions, if applicable, as well as any warnings or cautionary statements and potential side effects
56
T/F: Nutrients typically have both an RDA and an AI
False, they have on or the other
57
T/F: All nutrients can promote symptoms of toxicity if consumed in excess
False, many nutrients do not have an upper limit - meaning we do not have sufficient evidence to show that they cause symptoms of toxicity above a certain level
58
In addition to grams, nutrient amounts on a nutrient facts box may also be expressed in ______________
Daily values
59
T/F: “Contains strawberries” is an example of a nutrient content claim
False, it is a highlighted ingredients claim
60
T/F: “Won’t cause cavities” is an example of a nutrient function claim
False, It is a disease reduction claim
61
T/F: “Won’t cause cavities” is an example of a nutrient function claim
