  1. In Depth Protein Breakdown


    Types of protein and functions:

    Whey Protein Whey is the top of the pile when it comes to protein, the most popular and the most used among the proteins; 3 factors are the cause of this- affordability, effectivness and advertisment. Whey protein is a derivitive of milk and a byproduct of cheese making. When cheese is created, the milk is curdled, parting the curds and the WHEY. Remember the nursery ryme?
    Benefits of whey-
    *Contains a large quanity of immunoglobin protein which has the ability of enhancing the immune system
    *Contains the highest concentration of branched-chain amino acids (BCAAs)
    *Contains endogenous- most poerful, naturally occuring antioxidant
    * Ability to stimulate production of IGF-1 (Insulin like Growth Factor)
    *Whey is fast aborbing, quick to the muscle protein, this is why whey is so popular post workout, your body needs protein to begin repair to damaged muscles from workout as quick as possible.

    Casein Protein -Forms a gel once in the digestive track/stomach to help regulate time releasing of protein. Derived from milk. This "slowing" effect aids greatly in the absorbtion of amino acids (a good thing)
    Benefits:
    *Time released to provide the muscles with amino acids for an extended period of time
    *A large content of glutamine a muscle sparing amino acid
    *Contains glucogeni amino acids which have been proven to defer muscle breakdown when exercising.

    Milk-Protein Isolate - A combination of whey and casein protein, not much research has been done on this protein, but consumption of it is considered positive because of the contents of both casein and whey.

    Soy Protein - Derived from plants and has never been a large part of bodybuilding. Soy protein is approximatley 70% actual protein and is considered inferior compared to whey and casein. There is a soy protein isolate out on the market and new studies have shown that this protein is very solid in the bodybuilding world
    Benefits
    *Boasts a high concentration of BCAAs
    *Includes amounts of glutamine
    *Proven to have a positive impact on the production of T-4 and T- 3 and even insulin over the various types of other proteins.
    *Helps retention of nitrogen on a small scale and promotes fatloss during low caloric diets.
    * Lowering of triglycerides and cholesterol
    *Recommended dosages are 4 servings a day at 6.25 grams per serving.

    Egg Protein - Once deemed the "golden standard" of proteins, while this reputation has faded a bit, never count out this old school protein. Derived from...you guessed it...eggs
    Benefits
    *Illustrious amino acid profile
    *Provides a complete protein source
    *Conveinet and can be used in the making of baked goods, etc.

    *This is a brief breakdown of the styles of protein out there, I will now list the amount and types of protein in some of the most popular protein supplements-

    Thanks for taking the time to read this and again if you have a protein supplement you would like to add, feel free to do so, thank you, YJ


  2. Hey Yj. I eat 3 whey isolate shakes aday. But when I eat them it is with 1 egg and milk. IS that good for getting long and short protiens?? Talk to ya

  3. Yes, in my opinion thats one of the most solid blends, Im not a fan of soy protein and if anyone wants to know why I'll be glad to post it, but egg is solid, and whey isolate is the best out there in my opinion....do you make it yourself or you buy it blended curt?

  4. I use optimum. I guess it has some concentrate in it as well right?? Talk to ya

  5. Optimum's Pro Complex is pretty good, and lurking around a few boards seems to me the new favorite, Im gonna write one of these next week on meal replacements also, but the pro complex has an ion exchange/ cross flow micro-filtration whey and isolate whey peptides, a very nice BCAA get-up and its great if you're looking for low carbs has only 4 or 5 I think, maybe 6, but never the less its a good combo

  6. For night time would it be better to go 2 eggs and a litle more milk?? Talk to ya

  7. Yes, more milk would be ideal to get more casein in your system for that "down time" at night, keeps supplying your muscles with protein so you can grow while you sleep

  8. Thought so. Just wanted to hear it from the PRO.. hehehe. Talk to ya

  9. my fav. blend is metrx protein plus. (choc, its ridiculously good) on top of that, its thicker than most protein powder and you already know i like thicker shakes.

    If you don't like soy protein because of the estrogenic effects, just use soy isolate. It eliminates this problem.
  11. Thumbs up


    yj thanks 4 another great read.

  12. It is a good thread, but I've got one more question:  I always hear specific numbers on the BV and amino acid profile of Whey, Casein, Egg Albumin, and Soy protein--but what about meat?  Any idea of the BV and aa profile of tuna, salmon, beef, chicken, turkey, ham, etc?

    BUMP

    YJ... what happened to the one on meal replacements... hmmmmm?

  14. howdy,

    regarding the BV of different proteins. to be honest it doesn't really matter, most animal derived proteins are close (relatively speaking), however, this does not take timing into effect ( eg. meat immediately before or after workout-bad, a few hours before or an hour later it's great)

    i've actually seen a well run study that showed that casein only is better than whey only after a workout (although whey right after and 30 min later followed by a "slow" protein 60-75min later would be superior) i will try to find this reference if time permits (stupid exams)

    PS try a cup of cottage cheese right before bed every night instead of an MRP, cheaper and better or egg whites

    PPS whey isolate in mine and some faculty members in biochemistry and kinesiology at McMaster University (were i'm a student) is BS, concentrate has very similar amino acid profile and the supposed immunoglobins and microfrations get digested anyway and are absorbed as di and tripeptides. infants have holes in their intestines that allow them to absorb (could also absorb harmful stuff, that is why they are more succeptible to illness) such immunoglobins and other stuff, us adults do not

    This is true. The benefits so wonderfully stated by YJ are too good to pass up. 20-40 grams a day od soy isolate will do the trick

    PEACE

  16. Excellent post, YJ!

    I mix up my protein shakes throughout the day. I use Optimum's 100% Whey in the morning .... and then later in the day I use a blend of Milk and Egg Protein powder on one day and then reverse the order the next. I also throw in some Soy powder (that my wife has lying around) whenever the mood hits.

    Oh yeah, and the milk and egg really does give the shake a very smooth and "creamy" texture.

    Once again, great information. Thanks for sharing.

    Whey is useless at any time except postworkout. Any other time only about 30% of it is used. The rest is all just used for energy. Just stick with the egg and milk the other times without the whey except postworkout.

    i aint trying to nick pick here guy but "useless" usually refers to 0% affectveness....and even in your 30% percent case, whey has its place anytime of the day (best postworkout, and pretty ideal in the morning as well cuz you want a fast absorbing protein after you fasted for 8+ hours)
    Picking whey, casien, egg albumin (spell check that sucka), etc. has alot to do with price too. for some, its very economical to get a whey in bulk (5 lb and up) and intake cottage cheese/eggs for the slower proteins. anyways, i think for your proteins throughout the day other than post, its ideal to get a full spectrum of protein profile (whey, casien.....etc) in one sitting.

  19. Milk at bed?  What about carbs?  I am trying to understand this and PLEASE help me!  Are carbs before bed bad?  What is ideal before bed?  I usually do a tbsp of PB and whey shake with water.  I just don't understand the whole no carbs after 7 **** or b4 bed!!!

    HELP a bro out!

    The dangero f carbs before bed is over rated bro.....but whey with water before bed is a terrible idea, thats going to digest in roughly an hour, even with the added peanut butter man...

    I agree with the water, that was my fear.

  22. total agreement with YJ. Good idea to add in fats with your whey. If keeping your protein powder in whey is what you are going to do, atleast chuck in cottage cheese into your shake and cut back on the whey. So atleast you have a more diverse protein spectrum. (this also can replace milk, and have less carbs/sugar to deal with) And uknow what, the taste is not altered if your whey is of good taste (or atleast a strong taste).
    In the past, i had 2 sccops of either eas/opt/sportsone whey with 4 oz milk and 4-6 oz water and added pb. But with the added 1/2 cup of cottage cheese, i would add 6 oz water, C.C., pb, and 1.25 scoop whey. (the last part, i had do endure some nights of mixing and guessing to get the right thickness and taste.

  23. a half cup of CC!  That sounds sick!

  24. Just to add my 2 cents...A somewhat recent (2 years ago)study shows that for those of you interested in losing fat, soy protein might actually be a better choice than whey protein. Even though the study was done in mice, as you know alot things that work on mice work with humans. Check this out:


    Effect of soy and milk whey protein isolates and their hydrolysates on weight reduction in genetically obese mice.
    Author:Aoyama T, Fukui K, Nakamori T, Hashimoto Y, Yamamoto T, Takamatsu K, Sugano M., Volume:64 Issue:12, Page:2594-600 Year:2000 Dec


    The effect on genetically obese mice of a milk whey protein isolate (WPI) and soy protein isolate (SPI) and their hydrolysates (WPI-H, SPI-H) on the rate of body fat disappearance was investigated. Male yellow KK mice were made obese by feeding with a high-fat diet containing 30% fat from 6 to 10 weeks of age. They were then fed with an energy-restricted low fat (5.0%) and high protein (35% WPI, WPI-H, SPI or SPI-H) diet for 2 weeks at the 60% level of energy intake by mice on laboratory feed. During the weight reduction period, the body weight of the WPI, WPI-H, SPI and SPI-H groups changed by -9.1, -9.1, -10.0 and -11.1 g/14 days, respectively, the reduction being significantly lower in the SPI-H group than in the WPI and WPI-H groups. The plasma total cholesterol level was significantly lower with the SPI diet, and the plasma glucose level was lower with the SPI and SPI-H diets than with the WPI and WPI-H diets. Although the body protein content was comparable in all the groups, the body fat content was significantly lower with the SPI diet than with the WPI diet, and was also significantly lower with the SPI-H diet than with the WPI and WPI-H diets. The weight of the perirenal fat pads was significantly lower with the SPI-H diet than with the WPI and WPI-H diets. These results indicate that SPI and SPI-H are suitable protein sources in an energy-restricted diet for treating obesity.

  25. Very nice post Sheesh, Ive read that also.
