34
Based on the AHA, how much should you exercise for?
Aim for 30 minutes/day in at least 10 minutes/session
35
Based on the AHA, how often should you eat fish?
Twice a week
36
What is the effect of eating saturated fats?
RAISES LDL RAISES HDL RAISES TC
37
Is there a direct association between saturated fats and CVD?
NO. BUT, there is strong evidence that replacing SFA with PUFA reduces TC and LDL-C and the risk of CVD events. It is better to replace saturated fasts with unsaturated fats, then to replace them with carbohydrates.
38
What is the DGA's recommendation for saturated fats?
Retain the 10% upper limit for saturated fats.
39
Is trans fat saturated or unsaturated?
It is unsaturated.
40
Why is trans fat unique?
The double bond configuation is altered during hydrogenation of liquid oils.
41
Do trans fats occur in nature? if so, where?
Yes they occur in nature and the process occurs in RUMINANTS via bacterial hydrogenation.
42
What is trans fats affect on LDL and HDL?
RAISES LDL | LOWERS HDL
43
What is another name for omega-6 FA?
Linoleic Acid (an essential fatty acid)
44
What is the current ratio of Omega-6 to Omega-3? What do we want it to be for heart health?
Currently: 16:1 What we want: 4:1
45
What is another name for omega-3 FA?
Alpha-linolenic acid (ALA) (an essential fatty acid)
46
What are two other types of omega-3 fatty acids found in cold water fish and seafood?
Eicosapentaenoic Acid (EPA) Docosahexaenoic Acid (DHA)
47
What is the AI for n-3 FA?
1. 1 g/day for women 14+ | 1. 4 g/day for men 14+
48
What is a benefit of consuming omega-3 FA?
It has been found to reduce TG levels and inhibit platelet aggregation.
49
What is homocysteine?
homocysteine is an amino acid that is found in the blood for a short time.
50
How does homocysteine become present in the blood and why is this a concern?
Homocysteine is found in the blood when methionine is metabolized. High levels are thought to cause damage to the linings of arteries and speeds up formation of blood clots
51
What is needed to reduce Homocysteine levels?
Folic acid, Vitamin B6 and B12 are necessary to convert Homocysteine to other amino acids.
52
What is the main source of fat for the Mediterranean diet?
MUFA oils are the main source of fat
