Why???

Why is everybody making such a big deal about the raw food diet and wheatgrass diet? Not one of these book authors that promote raw food, wheatgrass, vegan, vegetarian diets lived a ripe old age. Dr. Ann Wigmore only lived to be 85 years old. And she died a lonely old lady with a ton of cats. There are many people that lived alot longer than that that eat cooked food. So what is the big deal?
