Why are omega 3s and 6s essential? - (answer)the body cannot make the double bonds at the 3 and 6
carbon
What is the best source of omega 3s? - (answer)- fish (100% omega 3 content)
What are good sources of omega 6s? - (answer)- safflower oil
- sunflower oil/seeds
- corn oil
- walnuts
Which omega is more unstable and what does it result in? Where do they need to be stored? - (answer)-
omega 3s are more unstable
- can't be heated as high
- stored in cold, dark place
What are omega 3s indicated in? - (answer)- heat health
- mental/brain health
- decreased inflammation
Concerns of fish oil supplements - (answer)- possible contaminants
- unbalanced nutrients
- use food first approach
- fortified foods as best options
Fortified foods - ALA vs. DHA in the body - (answer)- foods like bread and yogurt are being fortified with
omega 3s and ALAs
- ALAs need to be converted in the body but the body is not good at doing that so DHA is better
- this is the reasoning for 2 servings of cold water fatty fish being recommend

What are the best oils to use? Why? - (answer)- Flax and canola are the best
- Walnut and grape seed is also good
- They have higher/highest content of omega 3s
What type of FA can be absorbed directly into the blood stream? - (answer)- short and medium chain FA
Are medium chain FA naturally occurring? What is the exception? Who are they good for and why? -
(answer)- Not naturally occurring
- found in coconut
- they are good for athletes because they can reduce lactate build up and help use fat as energy
How are long chain FA absorbed and transported into the blood? - (answer)- packaged into a lipoprotein,
specifically called a chylomicron in the GI epithelium
What does a chylomicron contain? - (answer)- cholesterol
- triglyceride
- protein
- phospholipid
Where are long chain fatty acids absorbed through, where do they travel? Where is the chylomicron
delivered? What if it's too big? What does it reform into? - (answer)- absorbed into lymph through
lacteal
- travels to the left subclavian vein and into regular blood circulation
- delivers chylomicron to fat cells
- if it is too big, it breaks down by use of enzymes to glycerol and FA which can be then absorbed into the
cell
- reforms into triglyceride
- stored as adipose tissue

What happens to the remnants of the chylomicron? - (answer)- Ex. cholesterol goes back to liver to be
recycles into other lipoproteins such as VLDL which are released into blood
What do VLDLs do? - (answer)- circulate in blood, drop off more triglycerides and LDLs are left circulating
in blood
What happens to LDLs? - (answer)- some can be taken up by receptors (only a limited number with help
of apolipoprotein B) on cells and disposed of
- some can be metabolized by HDLs
- LDLs left in blood to oxidize and build plaque on artery walls
What is the main mechanism to increase HDLs? - (answer)- exercise and healthy eating practices
Why was the portfolio diet developed? - (answer)- decrease cholesterol by having soluble fibre, nuts,
plant sterols, and soy protein daily
- they all individually decrease cholesterol but the impact is greater when combined
Basic metabolism of alcohol - (answer)- absorbed through the stomach
- males have more enzymes (MEOS)
What is considered a drink? (beer, wine and hard liquor) - (answer)- beer: 12oz (5%)
- wine: 6oz (10%)
- hard liquor: 1.5 oz (80 proof)
Acute health risks of alcohol - (answer)- impaired judgement
- emotional control
- coordination / reflexes
