I discussed this subject (the cause of heart disease, bypasses,etc.) in greatest details in my book Timeless Secrets of Health & Rejuvenation. Heart disease rarely runs in the family, but eating habits do. There is little point doing chelation or having a bypass operation when the root causes of heart disease remain intact. The most common cause is eating animal products, as well as milk, cheese, eggs, and fish. Hardening of arteries is easily reversable and should not be treated with such harsh methods as bypasses or stents. Mortality rates don't go down when the blockage is bypassed, because the large obstructions hardly ever cause a heart attack. What causes most heart attacks are blood clots breaking loose from behind soft, small patches of cholesterol that the body tries to attach to small arterial lesions and wounds, something that surgeries don't fix. And chelation offers only temporary relief, takes a long time and can be very costly.
