Would it be correct in saying saturated fat intake is the most important dietary risk factor of cardiovascular isease?

To much sat fat clogs the arteries to the heart,which can cause heart disease,you should have no more then 20g of sat fat a day to stay in the low risk range.

yes absolutely correct

I would say yes; Also smoking. I had a heart attack last June. One of my Coronary arteries was completely closed due to junk I'd eaten over the years-am aged 53. I was also a very heavy drinker until 21 years ago

Saturated fat doe's tend to clog up you arteries so yes I expect it is

I think you should add on toyour list cholesterol.

No, I would say it is #3. #1 is family history, as in how your body handles fat and cholesterol. #2 cholesterol and how much your body makes on its own. #3 saturated fat. I know a man that is 98 years old that has eaten pork fat all his life. I also know a man that is 44 and an ex-iron man runner that has had two hart surgeries to open his arteries because of cholesterol.
