4. Get the Good Fats
Older advice will tell you to avoid fats but this is something that is being challenged more and more by modern studies. Whereas fat was once believed to be linked to high blood pressure and cholesterol, it is now generally held that the right kind of fat will do more good than harm. In particular, that means seeking out natural sources of saturated fat such as eggs, beef etc.
These types of fat have been shown to raise HDL cholesterol (high density lipoprotein) which is the good kind, while lowering the bad kind: LDL. Do speak with your family physician before making this change though.
