Six Classes of Nutrients

Six Classes of Nutrients

Carbs, proteins, vitamins, minerals, lipids, water

Chemical nutrients

Energy (cals), nutrients, phytochemicals

Essesial Nutrients

Needed from outside the body (through food)

1000 Calories = ? kcals

1 kcal

How many kcals needed to raise the temp of 1kg of water

One kcal raises the temp of 1kg water

Energy Density

A measure of energy a food provides

Roles of energy yielding nutrients

Building tissues (muscle & skin), and regulating Activities (digestion & energy)

Carbohydrates

Organic, energy yielding, macronutrient

Lipid

Organic, energy yielding, macronutrient

protein

Organic, energy yielding, macronutrient

Vitamin

Organic, not energy yielding, micronutrient

Mineral

Inorganic, not energy yielding, micronutrient

kcal value of nutrient: carbohydrate

4kcal/g

Epidemiological Research Studies

Cross-sectional studies, case-control, cohort studies

Experimental Research Studies

Lab-based animal studies, Lab-based invitro studies, human intervention (clinical) trials

Parts of Published research

Abstract, introduction, methodology, results, discussion, references

Dietary Reference Intakes (DRI)

Set of intake values for healthy people in Canada. This includes:'

Estimated average requirements (EAR)

Reccomended dietary Allowences (RDA)

Adequate intakes (AI)

Tolerable upper intake levels (UL)

Acceptable Macronutrient Distribution Ranges (AMDR)

45-65% kcal from Carbs

20-35% kcal from fat

10-35% kcal from protien

Malnutrition

Caused by EXCESS or DEFICIENT nutrient intake

undernutrition

Caused by lack of energy or nutrition

overnutrition

Excess energy or nutrients

Anthropometric measurements

Height and weight
