Genetics do play a part in cholesterol. Usually when children do have high cholesterol, it is from hereditary origins. Research has shown that it is the quality of fat that makes the difference in lowering cholesterol, not an overall lowering of all fats. It is recommended that all Trans fats and saturated fats are not consumed, but omega-3 fatty acids and monounsaturated fats can be eaten. To break that down simply it means nuts, seeds, and peanut/olive oils can be eaten. Suggest having them eat a moderate fat diet to help lower their cholesterol. Moderate fat diet means = use polyunsaturated (omega 3, corn oil, nuts, etc) fats and monounsaturated (olive oil, canola oil, peanut oil, etc) fats, no saturated fats and no Trans fats. Eat low fat meats (chicken, fish, loin of pork) or non-meat sources (soy products, nuts), low fat vegetarian combinations (rice & beans, pasta & beans, low fat cheese & pasta), fat free or low fat dairy products (skim milk, 1% milk, low fat cheese, low fat yogurts, low fat soy milk/yogurt), use plant oils, non trans-fat margarines, and eat a lot of fruits and vegetables. Eat daily high fiber breads and cereals (oatmeal). Hope this helped you.
The only report I can find off hand right now is for my 8 yr. old, the one w/ the 11 HDL. It says:
LP+LDL Direct
Chol. Total 110 w/ normal being 11-169
Triglycerides 122 w/ normal being 0-149
HDL 11 w/ normal being >39
This all threw his T. Chol/HDL Ratio to 10 which was high, normal is 0-5.
