What causes a high ldl and what and what can be done about it?

LDL is Genetics: Ldl is about your genetics and there is little you can do to change this risk without medication. Now, the other components, the HDL and the triglycerides can be significantly improved with diet and exercise, LDL is about your genes. This is what we use statins for: to lower LDL cholesterol.

Fatty foods, etc.,,,: Apart from genetics, a high LDL can be due to intake of fatty foods like dairy products and eggs and pork and red meats. These have a lot of saturated fat and help contribute to a high LDL value. So avoiding these foods, along with exercise, will help lower the ldl. Good luck.

Follow the following: Exercise most days of the week (aerobic work), eat fruits and vegetables liberally, limit saturated fats, increase fish and fish oil intake, have fiber with each meal, keep your weight in check, don't smoke at all or drink excessively (one or two drinks weekly). The lower the better on LDL and the higher the better on HDL. Could be diet, sedentary life, genetics raising your LDL.
