Lower LDL - Raise HDL
I found this bit of research today :
For every 1 percent increase in good (HDL) cholesterol or 1 percent decrease in bad (LDL) cholesterol, your risk of having a heart attack or stroke drops by 2 percent.
So if I can drop my LDL level by just 20% - and raise my HDL by 20% - I will reduce my risk of heart attack or stroke by a massive 80% !
