Protein Shakes Question?

[my3stars 88]

Went to my pre op seminar & they said I should buy Protein in this order: whey protein isolate first then whey protein concentrate second & less desirable is soy protein. Does anyone know what is the difference?

I bought two tubs of pure protein and they are concentrate & now am curious as to the difference, thanks in advance!

Don't buy too much in advance because your taste changes. Get some samples to get ya started! I personally don't like what I am hearing about soy! But definitely listen to your doctor.

Definitely don't over buy before surgery. I have two tubs of it that I liked before but can't stand now.

Protein isolate from my understanding is the purest most well absorbed form of protein out there. I also stay away from soy due to high risks of breast cancer from all my aunts.

Thank you ladies, I bought them for my pre op liquid diet for two weeks hopefully I will get through them in that time!

I am sorry but what do you mean by "quality", thanks!

There are better quality shakes. I like GNC and cyrosport complete whey.

whey was once considered a waste product from the process used for making cheese. It is a highly digestible, complete Protein made from cow's milk. Whey concentrate is about 80% Protein with relatively low levels of fat, carbohydrates, and cholesterol (but still higher than whey isolate). So whey concentrate not only has a high percentage of protein but also provides healthy fats that boost the immune system. But if you're lactose intolerant, whey isolate may be easier to digest.

Whey isolate goes through an additional micro filtering process that is not used in producing whey concentrate. As a result, whey isolate is about 90% protein. Micro filtering removes the lactose and fat but also destroys many of the immune system boosting properties of whey. Whey isolate can also be significantly more expensive than concentrate because of the additional processing required.

The digestibility of various Proteins is published in the Protein Digestibility Corrected Amino Acid Score (PDCAAS). The PDCAAS has been adopted by the Institute of Medicine at the National Academy of Sciences, the U.S. food and Drug Administration, and the World Health Organization. Proteins are ranked on a scale of 0 (least digestible) to 1 (most digestible). Whey, Soy, Milk, and Casein proteins all have a PDCAAS score of 1.0.

The bottom line is that with whey isolate you get more protein per gram (but not necessarily any better) and it may be better handled by those who are lactose intolerant. With whey concentrate you get slightly less protein per gram but added benefits from the higher fat content. As several folks have noted, the first test that any protein you're going to drink or eat has to pass is - taste. If you are not lactose intolerant and you find a protein that you like, the difference in protein content for whey isolate vs. whey concentrate vs. milk concentrate should likely be a minor consideration.

One word of caution - stay away from the protein "bullets" and "shots" that you will see in stores and read about online. If you look closely at their ingredient list, you will see that they are made with collagen protein. These products are attractive to bypass patients because they contain very large amounts of protein in very small volumes - usually 3 to 4 ounces. The problem is that collagen protein is an incomplete protein (meaning that it is missing one or more of the nine essential amino acids that your body requires and cannot manufacture) and more importantly, collagen has a PDCAAS digestibility score of 0.08. All the protein in the world is useless if your body cannot digest it.

Thank you soooo much, I knew you would have the answer! I bought the pure protein and will not be trying them till next week that I begin my liquid diet. When I initially had my RNY they did not have the wealth of information they have now and since I am getting a "second chance" I am trying to learn everything as it is new to me! I tuly appreciate your knowledge, great advice and most importantly your willingness to always share it...

The sf coffee syrupsare sold at Amy local grocery store. As far as Protein shakes, the Jay Robb brand is very good, not gritty and comes in many flavors.
