On the heart disease issue Dr Henry Bieler answered this issue in his 1965 book Food is your Best Medicine. I think Aajonus Vonderplanitz answered the same in his 2 books.
Raw fat, raw protein leads to natural pure blood cholesterol, the way nature intended it to be. Cooking fat and cooking protein gives people corrupted cholesterol like building a house with corrupted cement.
On the kidney issue Dr. Henry Bieler in the same book argued that a simple lab analysis of urine shows the defects of eating cooked protein. Eating raw protein is truly best he says. Eating cooked protein all the time will be hard on the kidneys and lead to destruction of the delicate globules.
