21
Q

The interheart study states MI risk increases with increased cholesterol, increased non HDL cholesterol, apo B conc and a decrease in HDL and Apo A. Apo B/Apo A1 ratio was a better risk marker of MI than the ratio of cholesterol/HDL. Apo B better marker than cholesterol and LDL. And Apo A1 better than HDL chol

A

McQueen et al 2008

22
Q

McQueen 2008

A

Interheart study MI risk Apo a1 and Apo B

23
Q

Best way to improve blood lipid profile is to replace Trans fats with unsat fats from unhydrogenated oils. Also to replace sat fats with cis unsat fats decrease cad risk. Not high carb diet

A

Mensink 2003

24
Q

Mensink 2003

A

Replace Trans with unsat. Replace sats with cis unsat

25
Q

Liu 2000

A

Increase fruit and veg

26
Q

Increased fruit and veg decreases risk of MI and protective against CVD.

A

Liu 2000

27
Q

Kromhout 2011

A

Low sat fat, low as poss Trans. Make sure fulfil n3 and n6s

28
Q

Low sat. Low as poss Trans. N3 and n6. 5% sat fat replaced by n6 equals 10% decrease in chd. People who eat fish once a week decrease CVD by 15%

A

Kromhout 2011

29
Q

Astrup 2010

A

Chd risk decreased when sat fats replaced with pufas. In western diet 1% of energy from sat replaced with pufas lowers LDL could reduce chd by 2-3%
