Can using margarine instead of butter help lower my cholesterol?
Not really. Both margarine and butter are high in fat so you have to use both in moderation. But from a dietary point of view, saturated fat is a major factor in affecting blood cholesterol, and soft or liquid margarines have less of this fat. This makes them preferable to the stick forms. The best option would be to buy trans fatty acids – free margarine. But the rule of thumb still remains: eat ALL fatty foods in moderation.
