Got this from my cousin: [Looks to me like a buildup of protein “Waste Products”
certainly can cause kidney or liver damage.] Medical Information: Kidney Disease (Kidney Failure, Nephritis)
Among the most subtle and important of the many toxic threats to the kidneys are the excess amounts of proteins that are consumed by the average person who eats our rich American foods. The daily intake of more proteins than the body really needs means that the excess must be eliminated through the kidneys. We're equipped with no storage depots for proteins, as we are for fats.
The proteins not used for body repair and growth float around in the blood stream until they are metabolized by the liver and their remnants are removed by the kidneys. The filtering units in the kidneys are called nephrons. Destruction of these nephrons occurs directly from exposure to those proteins or to the products of their degradation. The damage from excessive intake of proteins is so common that, in an otherwise healthy person, 25-50% of the functional capacity of the kidneys will be destroyed after eight decades of high living American-style. Even so, we're lucky to have much reserve tissue to rely on: with only 25% of kidney function remaining, plenty of tissue cells still survive to handle the waste products of body metabolism, and the damaged and failing kidneys go unnoticed. Our bodies are very forgiving!
So looks to me like indeed this paragraph is indeed correct.
Quote from CC: ""A buildup of protein waste products causes kidney or liver damage. High-protein diets often promote foods such as red meat and full-fat dairy products. Some experts believe a diet rich in these foods can increase your risk of heart disease. A high-protein diet may cause liver or kidney problems because the body may have trouble eliminating all the waste products of protein metabolism.""
