Beef Protein Isolate

[G1981C]

I have found this:

http://www.truenutrition.com/p-1075-...late-1lb.aspx?

Unlike the mainstream beef proteins this one can be had plain or sweetened with stevia.

The thing is though ... why is Beef protein so cheap ? It is significantly cheaper than simply freeze dried beef - what gives ?

Klokov said "if you eat meat you meat" and i believe that a lot more than i believe the hype from whey manufacturers. i really want to try a protein made out of actual meat ... but why is it so cheap and why are so few people using it ?

I hear the taste is not the best ... but really, are we some kind of pussies ?

Beef protein isolate is more expensive than whey and has a poor amino acid profile. It's a waste of money.

Beef protein isolate is more expensive than whey and has a poor amino acid profile. It's a waste of money.

but how do we know what is the optimal amino acid profile ? also, how bad can the amino acid profile be for something that is made out of muscles ?

it seems the reason reason whey is so popular is because it is made from an abundant and cheap by-product of cheese manufacturing and because it has a taste that works well the most popular flavors, namely chocolate and vanilla.

in other words solid PRACTICAL reasons, rather than performance reasons, but then the marketing departments step in and start with the hype and before long everybody is convinced that whey is the holy grail and highest performance protein available.

i think the real reason people think whey is the best is because whey is most profitable protein and thus the most money was available to hype it up. most people don't realize how easy it is to swing public opinion on any given subject, but it is done all the time. public opinion also frequently makes 180 degree turns on the most crucial subjects such as whether it is better to eat low fat or low carb, whether cholosterol or saturated fat are good or bad etc. in other words, just because "everybody knows" that whey is the best protein is not reason enough for me to believe that it is. it is probably the most practical protein though.

yes i understand whey is the fastest protein, but unless you take protein every 3 hours like a pro bodybuilder that speed advantage is a moot point.

in my quest to diversify from whey and casein i already take collagen and hydrolyzed collagen ( gelatin ). i stopped using egg white protein over concern for avidin. the next logical step ( for me ) is to try beef protein ... i think.

i was just trying to find out if there are any serious problems with it like terrible taste or some kind of toxicity etc ?

if the biggest objection to beef protein is that whey is better / cheaper i think i will give it a shot.

We know that 3-4g of leucine maximizes muscle protein synthesis in virtually all humans (regardless of size). Whey contains 3-4g per 20g of protein with ~120kCal for this concentration of leucine. Any other protein source with more calories and less leucine can be deemed a "suboptimal" protein source. Moreover, we need 1 valine and 1 isoleucine per leucine + the rest of the EAAs to drive muscle protein synthesis. If a protein supplement, say beef protein isolate, contains less of these things per equivalent serving than a lesser priced alternative (whey) then we can uneqeuivocally say that beef protein isolate is not the best choice for anything, period.

All this is nonsense. There is legitimate science that put whey as the king of proteins. Additionally, it's cheaper and tastes better.

It's not the fastest (hydrolyzed casein or bcaas are, technically) but it does raise blood amino acid levels the fastest, for the longest time, and is the most satiating.

in my quest to diversify from whey and casein i already take collagen and hydrolyzed collagen ( gelatin ). i stopped using egg white protein over concern for avidin. the next logical step ( for me ) is to try beef protein ... i think.

Collagen does not contain the correct amino acids to drive muscle protein synthesis. It is, 100%, a waste of calories from a protein intake perspective. When you cook egg whites (and egg white protein is cooked), avidin is denatured- thus it cannot block biotin absorption anymore.

It does taste bad, it's more expensive, and less effective. Then again, knock yourself out.

Beef protein can be made from tendons, sphincters, and penises. Not that there is anything wrong with that. But by products like how they make dog food.

Whey seems a little more uniform. Maybe cute cows vs ugly cows?

Paleo cows vs gluten eating cows.

A fucking perfect paragraph. May I quote this if I ever get asked 'why whey'?

Paleo cows vs gluten eating cows.

I'm going to go with gluten cows. Better fatty acid profile than corn fed. Paleo cows can give you CJ disease.

Of course. Comb your hair afterwards.

Less gluten= beta pleated sheets.

Is that some open source copy left stuff there? Cause I'd prefer to use that perfect paragraph as it were, but I prefer the hair flip(tm) to the hair comb.
