If you have high cholesterol (a total cholesterol level of 240 milligrams per deciliter of blood or above), taking steps to lower it can greatly reduce your chances of having a heart attack. For every 10% drop in your cholesterol level, your heart attack risk falls by 20% to 30%.

1. Choose healthy fats. Avoid saturated fats, which increase unhealthy LDL levels and steer clear of trans fats, which both raise LDL and lower protective HDL. Instead, substitute healthier unsaturated fats found in fish, nuts, and vegetable oils.
2. Go with whole grains. Whole–grain breads, pastas, and cereals help prevent a blood sugar roller coaster and make you feel full longer. Many of these foods contain fiber, which can help lower LDL levels.
3. Make other healthy choices. Eat more fruits and vegetables. Ideally, substitute these for processed foods and sweets. Choose fat–free milk instead of whole milk. Opt for low–fat yogurt and pick brands that are not loaded with sugar.
