In Your Cholesterol Matters Dr. Furman wants you to understand what your cholesterol numbers mean, how best to change levels of both the 'lethal' LDL cholesterol and 'hero' HDL cholesterol, and how to adjust your lifestyles in order to stay off of expensive medications that don't address the whole problem (and often have negative health-impacting side effects). Not only will Dr. Furman's advice make you healthier in the short term, it will also enable you to have more control over the aging process, allowing you to a live longer, better life.
