Eggs used to have a bad rep because of their cholesterol content, but most studies seem to suggest that eggs don't really raise cholesterol all that much, even though they have a lot of it. Maybe it's because the body doesn't absorb all the cholesterol that's in them. And eggs are fairly low in saturated fat relative to the amount of cholesterol they have. I have never shied away from eggs, and my cholesterol has always been low.
What you really need to watch out for is saturated fat and trans fat. Saturated fat raises both your bad (LDL) and your good (HDL) cholesterol, and at least it's a natural molecule that your body knows what to do with as long as you don't eat too much saturated fat. (Some also claim that the relatively short saturated fatty acid chains in coconut are healthier than the longer saturated fatty acid chains in butter and meat. I don't know if that's true although I do like coconut and enjoy eating it in moderation.) Although saturated fat is not as healthy as monounsaturated fats or some polyunsaturated fats, it is more stable at high temperatures and doesn't easily degrade to something worse like unsaturated fats can when exposed to heat. Anyway, limit your saturated fat intake.
Trans-fat is totally worthless. It is a relatively straight molecule like saturated fat (which is why it is generally solid) but it's chemically different from saturated fat and the body doesn't really know what to do with it. It raises your LDL and lowers your HDL cholesterol. Any food that contains partially hydrogenated oil (margarine, shortening, French fries, donuts) contains trans-fat. I don't eat anything I know to contain trans-fat, and I recommend others do the same.
Anyway, a healthy balanced diet (veggies, lean meats, nuts, whole grains) combined with exercise should result in lower LDL and higher HDL. Hopefully that will work for you. If not (i.e., your cholesterol remains well above 200 in spite of your best efforts), you should talk to a doctor about it.
BTW, HDL and LDL are themselves not cholesterol, but are actually the molecules that transport cholesterol. HDL and LDL are what get measured from your blood to get some idea of your cholesterol situation. It would sort of be like estimating how many people are driving to work based on the number of cars that pass by.
