High cholesterol is something I have been dealing with for several years. Everyone is different so solutions vary from person to person. My doctor put me on Zocor and it worked for a while, but I started getting aches and cramping in my extremeties, even in my back muscles. He changed to a generic statin that works much better for me. However, proper diet and exercise needs to compliment drug treatment. I'm not saying Zocor is a bad drug; it just did not work for me.
There is ample information on the net about proper diets to help reduce high Cholesterol. Generally, I try to make a habit of oatmeal for breakfast and avoiding typical fried breakfast meats, but turkey sausage is an acceptable alternative. I really like grilled or baked fish, so that is a plus. Chicken and turkey works if it is grilled or baked. I keep a package of frozen chicken breasts on hand, throw one on the grill while frozen. It cooks quickly. Tossed salads do the trick if you don't load them down with high fat dressings. Omega three and flaxseed suppliments is suppose to be helpful and I use them. Yes, cod liver oil has high marks, but I can't handle the taste and smell.
It is not easy to change a lifetime of eating whatever you like and crave. Although I realize pizza and red meats are not good for me, I still enjoy them occasionally. You have to live a little, but eating foods with high dairy content and visiting the hamburger joints several days a week will not cut it. When I do endulge in fried foods, I use virgin olive oil and make a serious attempt to avoid foods fried in vegetable oil or animal fat.
I have some friends that eat any and everything they want and never have this issue. All I can say is they are very lucky. In my case, I'm convinced my cholesterol problem is a genetic thing. When my doctor first discovered the problem, he wanted to put me on a statin drug immediately. I refused and assured him I would change my diet, which helped only slightly. It took medication to resolve the issue.
