article is 33 years old. This article correlates animal protein intake with production of Calcium Oxalate. Since he had no records he had no idea what type of stones he was forming. There is also a correlation between TONS of nuts and vegetables and stones. The point being that his statement that vegetarians have lower numbers of stones is unfounded and that animal protein causes them is ludicrous. There are dozens of factors that cause stones, water intake and heredity being two major factors. Search Google and you can find someone saying anything you want.
"A small amount of dietary protein can be converted to oxalic acid in the body and excreted as such in the urine. In addition, dietary protein is known to enhance calcium excretion in the urine.
Both an increase in oxalate and calcium in the urine can result from increasing dietary protein
Therefore, a greater dietary protein intake will usually increase the TSI. As a result increased dietary protein will likely contribute to kidney stone formation. The risk of kidney stone formation seems greater from animal than vegetable proteins, but this is still the matter of some scientific debate.
SO any protein will tend to increase stones, they say slightly more with animal protein, but they are sitting the article you site and it is 33 years, meaning no better research has been done since then, and using it as an authority for animal protein causing stones is grasping at straws at best.
I could debate diet all day long, but that is not really my point. My point is this guy is an idiot using second hand knowledge to come to the conclusion that Jobs got cancer working at a factory at age 15 in Silicon Valley not from a vegetarian diet. Coming to the conclusion that a vegetarian diet or a job at 15 caused him cancer is COMPLETELY idiotic, unscientific, and unfounded. BTW Jobs was born in 1955 and the US stopped using leaded gasoline in 1986, everyone should have pancreatic cancer if lead caused it. How does he come to the conclusion that his exposure to lead from soldering caused him cancer? The guy is an embarrassment.
All I am saying is the guy is an idiot.
