You brought up a good point: You said: “I don't have that much interest in looking at the laws for raw milk unless I'm also going to find out about the operation that produces the truly raw milk to make sure they're using sanitary procedures, especially their feed...which is important since there is no line of defense. That said, if I took the trouble to raise my own cows, I would drink raw milk.”
I agree that the source of the milk is important. Below is a link to some reviews I found about a product offered by the company from which I get my whey protein. I haven’t verified the reviews. They mention the other whey product that I used to use, but I switched to the newer version because it’s a certified organic product. Some of the reviews mention that the cows are grass-fed.
In regard to the laws you referred to in your earlier post, I spent a little time looking, and here’s what I found (see below). I'm not a lawyer, so I don't want to try to interpret what these mean:
The processing of whey protein products is governed by the Code of Federal Regulations in Title 21CFR, Part 184:
Section 1979(b)(3) reads as follows: "The whey must be derived from milk that has been pasteurized, or the whey and modified whey product must be subjected to pasteurization techniques or its equivalent before use in food."
Whey protein concentrate is specifically dealt with in 21CFR184.
Section 1979c.(b)(3) reads as follows:
"The whey protein concentrate shall be derived from milk that has been pasteurized, or the whey protein concentrate shall be subjected to pasteurization techniques or its equivalent before use in food."
The FDA Pasteurized Milk Ordinance of 2009 says in part:
"3. All milk and milk products shall be pasteurized, prior to the entrance into RO, UF, evaporator or condensing equipment, and shall be performed in the milk plant where the processing is done, except that:
a. If the product is whey, pasteurization is not required, provided:
(1) The product is acid whey (pH less than 4.7); or
(2) It is processed in RO or UF equipment at temperatures at or below 7oC (45oF)".
I have found that my body processes this protein better than many other types I’ve tried. I guess it all comes down to personal preference.
I have taken the following statement about Whey to Health from the company’s website:
“Protein concentrates have high biological value- they supply a high amount of the amino acids your body needs. A protein's function depends on its shape. Unlike many protein isolates, our whey protein concentrate was not exposed to extreme temperatures or changes in pH that might alter the activity of the proteins by changing their shape during processing. Whey to Health supports your body's essential protein requirements with a unique profile of highly bioavailable proteins and immune factors, including branched chain amino acids (BCAAs), lactoferrin and immunoglobulins. Whey is one of the most easily digested forms of high quality protein. It is low in carbs and can be used in conjunction with a variety of diet and exercise programs.” http://www.sourcenaturals.com/products/GP1812/
