HCl concentration in Stomach Acid

I recently saw an article on the e-caps website. It was a question for 'Dr. Bill' asking "If fluids should be consumed with meals? and was in response to a question posed on this bulletin board concerning: "protien digestion in diluted HCl-acids", and referenced your argument against drinking fluids with meals. My question is in regard to a statement that "Dr. Bill" made in this article: "Freshly secreted gastric juice is 0.4 to 0.5% HCl by mass, or about 0.1 M HCl with a pH of about 1.0" Basically I need to know if that is a true statement. I am making a simulated gastric juice in my lab, and I would like to have this 0.4 - 0.5% HCl concentration, but I need more proof than a statement on a website article.

What they teach in med school is that the pH is between 1 and 2. I suggest you find the medical school or university library closest to you and look it up in a physiology text book.
