To most, it just doesn't matter, food is pleasure. Meat, cheese, milk, dairy, eggs. These are the staples of every meal. 91% of the diet of Americans comes from these groups + processed foods. 9% is split between fruits, vegetables and starches.

A stent may save your life. Bypass may save your life. If you don't change your lifestyle/what you eat/drink, it doesn't matter. You can bypass the bypasses. Re-stent the stent. If you just take a pill and keep eating meat, dairy and eggs, you will be right back in the same boat or dead.
