Protein Utilization: How Much is Absorbed
As a bodybuilder, you must consider the net protein utilization (NPU) or rate of protein absorption into the bloodstream. For those who are trying to shed pounds this should be highlighted because some meat items are much higher in fat than others. For example, beef and chicken both have an absorption rate of 68 percent, yet chicken has the advantage of easier digestibility and contains almost half the calories of an equal weigh of beef, pork or lamb.
The protein utilization rate of some common foods follows.

Food NPU
Eggs 88%
Fish 78%
Dairy products 76%
Meat 68%
Soybeans 48%
Natural brown rice 40%
Red beans 39%
Coconut 38%
Nuts 35%
White beans 33%
Maize 25%
Whole wheat bread 21%
White bread 20%

The average person needs a daily quote of 1 gram of protein for every kilogram (2.2 pounds) of body weight. Adult males should consume 75-100 grams per day; however, an extra allowance of protein is required to build muscular weight for those in heavy training. The food intake tables found at the end of this chapter were calculated to accommodate both male and female bodybuilders whose goals range widely from training for good health and a vigorous appearance to entering competition at championship levels. My own intake of protein is high due to a schedule of heavy weight training, so I always take care to choose the best sources. In addition to eating only prime cuts of meat and making a point of having fresh fish, I also include eggs in my daily food intake since they have the highest protein utilization rate, as noted above.

When the consumption of protein is increased, the body does not automatically secrete more hydrochloric acid (HCI) to aid digestion. Therefore, if you are in heavy training and have increased your intake of protein it may be necessary to take HCI and digestive enzyme supplements. The role of enzymes during the digestive process is discussed in greater detail later. Most importantly, you must learn to judge what is best for your own body because it is essential to the learning process, and you learn to see yourself as a unique individual, a point of great value when you are in competition, standing on that stage and posing for those judges.

In summary, the best bodybuilding foods from animal sources are fish, meat, eggs and poultry. Dairy products like cheese are high in protein but also in fat, which tends to form fat deposits under the skin, causing loss of definition. The best foods from plant sources are beans, nuts, seeds and grain products.

I do know that Tuna is pretty high in mercury so it's not something you want to eat everyday anyway so eat some egg whites and packaged salmon, then eat the Tuna just 1 time a week.

Eating canned tuna twice a day has no consequences for the non child bearing male.

Im pretty sure egg whites are fast absorbing and Tuna, like any other sort of meat/animal, is slow digesting.

Ronnie might be in trouble then :o.

The tuna would digest slower. A good rule of thumb to remember- the more you have to chew your food the slower it is to digest. Milk should be faster than egg whites. Fat helps slow digestion also. If you're looking for fast digestion go with whey protien. The small amounts of mercury in the tuna are nothing to worry about. I used to eat 3 to 4 cans a day because it is cheap. Depending on where you live, egg whites can get expensive.

Except, milk isn't faster than egg whites. lol

arnold, start using the search function, a lot of the threads you've started and questions you've asked have been answered multiple times.

There's a wealth of information on the forums, you'd be pretty suprised what a simple search can offer.

Cheers

To my knowledge, milk is casein which is a slow releasing protein.

milk also contains some whey... I think there is more casein than whey through.

this message is frightenning!! it really contains mercury???!!!
and is canned salmon comparable to canned tuna (in protein)?

[stormysworld]

okay sorry about that I didn't realize that I was replying to a man. Someone said that it's not harmful to non child bearing males to eat mercury lol. I beg to differ. Mercury is a poison any way you look at it. Imagine what the liver has to go through not to mention the rest of the body when it's got mercury in it 24/7 You might want to think about that. Packaged salmon is comparable in protein. Infact let me look ....
yup, I got honey boy fresh pack pink bonless, skinless salmon and it's 2g less protein but also WAY less mercury so just eat more of it. I think I paid about 1.25 per pack. There are 3 servings in the pack but I split it into 2, add a little egg white and eat it on sugar free whole wheat bread.

Are "Eggbeaters" ok or should one stick to seperating whites from the egg?

I didn't say mercury isn't poisonous to non child bearing males....I said canned tuna twice a day, isn't poisonous.
