Comparing proteins

[buksoon]

Okay, I know about the basic proteins (whey is most quickly absorbed, good post-workout, caseinates slower, better throughout day, etc).

But what about some others like "lactalbumin"? How is lactalbumin different than regular egg protein/milk protein mix?

Also, if eggs need to be cooked before the protein will be digestible, what does that mean for egg protein powder?

And soy is not a "complete" protein, but some say it still counts and is good for building muscle; others say no. Which is it? And what if it's combined with another protein, as it often is?

bump, not because it'll have any practical benefit to me but because it's useful info

Good question - I'm interested in it myself. But I can only address the SOY issue from my own personal perspective. From what I hear, the amino chain in SOY is not nearly as what it should be for cell repair when comparing it to whey. If that is the case, then quite simply, why waste time with soy when vital parts of the chain may not be present or when you can get so much better? I know people drink soy milk because they can't have the regular milk but as far as the protein content, I don't see the benefit when you can get better. Just my .02.

But Mark, most of the KETO products (the product line is called "Keto" b/c it's low or now carb) is almost exclusively soy protein isolate.

Does that mean it's not good for building muscle? And again, what if other proteins are added? Soy is far and away the main protein in my diet and I want to build.

I'm a little confused when you say KETO Products. Are you specifically referring to products that a company is selling you or just supermarket products which are suited for the KETO Diet? If the latter, then Tuna, eggs and chicken and 93% lean burgers should not be a problem. All these sources have the amino chains that you want for muscle building. As far as a protein whey supplement, you'll just need to take it with liquid other than milk if u r concerned about the milk carbs (The whey protein powders I don't believe have many carbs in them) although I don't see how 12 gms of carbs can radically upset the diet - remember its a LOW carb diet.

If you are buy chance buying protein products from a company promoting a KETO diet, then personally,
I would stop. I simply would make sure you are getting the best protein for muscle building (which is easily achieveable on a KETO diet) and chemically speaking, SOY is not it - plain and simple.

Hopefully MS Bodybuilder, Blood-drinker, Mr X or some of the other people on the board can offer some other alternatives. Hope this helps.
