Nutrition 2P20
The Paradigm Shift
- Before: obtaining all the nutrients needed for good health
- Now: limiting consumption to prevent obesity and chronic disease
The leading causes of death in Canada are Cancer, Heart Disease and Stroke. All nutrition
related deaths.
45 nutrients are essential to human life and must be supplied by diet
6 classes of nutrients: Carbohydrates, lipids, proteins, water, vitamins, minerals
Maroutriets…
Dietary Carbohydrates: 4 kcal/g
- Starches = storages form of CHO in plants
- Glycogen = starch form of CHO in human body
- Fire = ostl udigested, does’t proide eerg
Dietary Lipids: 9 kcal/g
- Triglyceride = storage form of lipid in the body
Dietary Protein: 4 kcal/g
- Not as energy dense as fat
Water
- Macronutrient because it is required in large amounts
- Does not provide energy
- 60% of human weight
Miroutriets…
Provide no energy but are essential for proper functioning
Vitamins
- organic molecules
- 13 major (A, B [1, 2, 3, 5, 6, 12, Biotin, Folate] C, D, E, K)
Minerals
- inorganic molecules
- 7 major (Na, P, S, Cl, Mg, K, Ca)
Futios of Nutriets…
Providing energy
- kcals

Choosig a Health Diet…
Nutrient density
- nutrients a food provides compared to its energy content
- a nutrient-dense diet is a healthy diet
- avoid EDNP foods: energy dense, nutrient poor
Eat a variety of foods
Everything in moderation
APPLICATION QUESTION
1 small bag of plain chips contains 3g of protein, 21g of carbs, and 14g of fat, how many kcal
would this bag of chips yield?
- 3x4, 21x4, 14x9 = 222

Nutritio reoedatios for the Caadia Diet…
Dietary Reference Intakes (DRIs)
- 4 sets of values
- Estimate average Requirement (EAR)
▪ Estimated average requirement of a nutrient to meet the needs of half of
the healthy population of a particular sex and life-stage
▪ Mean = median = mode
▪ If we recommended EAR half of the population would not meet
requirements
- Recommended Dietary Allowance (RDA)
▪ The recommended target intake of a nutrient for an individual. 2 SD
above EAR
▪ Everyone meets required at the RDA
- Adequate Intake (AI)
▪ Average daily amount that appears sufficient as an estimate
- Tolerable Upper Intake Level (UL)
▪ The maximum daily intake of a nutrient unlikely to cause adverse health
effects
Energy Recommendations
- Estimate Energy Requirement (EER)
▪ Used to calculate total energy intake needed to maintain body weight
(energy balance)
▪ NTK age, eight, height se, PA to alulate’
- Acceptable Macronutrient Distribution Range (AMDR)
▪ Range for healthy intake
▪ Carbs (45-65%)
▪ Protein (10-35%)
▪ Fat (20-35%)
