Nutrition
Fat (lipid) is NOT bad
fat=solid (crisco, butter, lard)
oil=liquid (corn oil, olive oil, etc.)

High energy- 9cal/gram (fat has double the calories of carbs)

Body needs fat! It:
makes hormones
stored energy
insulates body/organs; cushions
meylin (covers most nerves)
gives shape to body
shock absorber (esp. for organs

Types of Fat:
1- triglycerides: basically stored energy. You have to consume these and this is the one that matters for heart disease, not cholesterol.
2- phospholipids: transports hormones and fat soluble vitamins (A,D,E,K)
3- Sterols: fat plus alcohol
-HDL, LDL, VLDL (high/low/very low density lipoproteins) HDL is the good one
4- Fatty acids or EFA (essential fatty acids)
-Omega 3 (source is important and it is unsaturated), 6 and 9- we get from diet
-Saturated and unsaturated

Psychology

Cathy's group (although I think we all do similar stuff)
Homework: Journal on the class experience (life raft, ennogram, ...), do an enneagram test on the internet, and try and read the 5 handouts



Anatomy
All of this is in Trail Guide p 306-315 (give or take a few)
