You can help lower your cholesterol by eating oatmeal in the morning for breakfast, limit the amount of red meat in your diet, and watch the saturated fats.

As far as how to use flax seed...we grind them with a spice/coffee grinder and add them to fruit smoothies, sprinkle them over cereals/oatmeal or salads. They taste very good. Over here they are evidently called linseed.
You can use flaxseed oil also...a teaspoon is considered a serving and it makes a very nice oil for used on salads.
