prevent toxicity, to get enough but not too much, aim for recommended daily allowance
Name the six classes of nutrients:
carbs (fuel source)
lipid (fat)
protein (make up bones, muscles and other tissues, energy)
vitamins (vital to life, metabolic)
minerals (no calories, growth/development)
water (solvent, lubricant, temp/chemical processes)
Macro vs micro nutrients
macro: carbs, lipids, protein
micro, vitamins, minerals, water
Main function of carbohydrate

Four types of fatty acids?
saturated fats, trans fats, monounsaturated fats, polyunsaturated fats (essential)
Two categories of vitamins?
fat soluble and water soluble
How are minerals categorized?
major: >100mg
