- Eat quality fats: use virgin olive oil and other unsaturated, low-cholesterol fats.
- 10% to 15% of your total calories should be in the form of monounsaturated fatty acids (e.g. olive oil, canola oil, and peanut oil).
- Talk to your doctor about vitamin D supplements.
- Eat foods that are rich in omega-3 fatty acids:
- Omega-3's are present in salmon, tuna, and mackerel.
- Walnuts and flax seed are also rich in omega3's.
- If you don't like fish, your local pharmacy has omega-3 supplements in capsule form.
