organisms
50yrs ago: home cooked meals, worked for meals,
How has nutrition preparation, leisurely eating
changed? Today: fast food, quick eating, less family dinner,
overconsumption
Nutrition related deaths cancer, heart disease, stroke
(TOP 3)
- Carbohydrates = 4kcal/g, used for energy, starches,
fibres, sugar
- Lipids = 9kcal/g , fats/oils, energy + storage
Macro nutrients
- Protein = 4 kcal/g, meants, energy and regulation
- water yum = transportation, lubrication, hydration, 62
of body!
, - vitamins and minerals do not provide energy but are
Micronutrients
needed for regulation of the body
- providing energy, forming structure, regulating
3 Nutrient Functions
processes
- undernutrition = deficiency of energy (lack of intake,
increased demands, inability to absorb)
Malnutrition
- overnutrition = excess of nutrients - toxicity, obesity,
heart-disease, etc.
food availability depends geography, SES, health status
