Hi Karen,
Don't you love genetics? I'm right there with you - strong family history of heart disease/high cholesterol.
It's great your HDL is so high, that's a definite plus. Here are three suggestions to lower LDL:
1. Evaluate your saturated and trans fat intake.
You state you eat a healthy diet, which is great. But double check the foods you are choosing to make sure your saturated fat and trans fat intake is low. You can do this by reading food labels and making healthy choices when dining out. Here's another post where you can learn more about saturated fat and trans fats.
2. Select a high soluble fiber diet.
Research has shown that for every 1-2 grams of daily soluble fiber intake, LDL (bad) cholesterol is lowered 1%.
3. Consider adding omega 3 fatty acids to your diet.
Here are three articles where you can learn how omega 3's are linked to lower cholesterol: Get a Grip on Fatty Acids, Top 5 Omega 3 Sources to Lower Cholesterol, Omega 3's - How much to lower cholesterol?
All the best,
