I will defer to Finch on all but one of his points...
nearly all of the protein in an egg is in the egg white. After doing a little more light research (2 google searches) it appears that all nutrients are, indeed, in the yolk. But nearly all protein is in the eggwhite.
Thus, the reason people suggest the whites for working out. It contains the building blocks for muscle.

The yolk does have protein, just not as much as the white. Its substantial, but the other stuff that comes with it outweighs its benefits on a large scale.
The yolk contains the cholesterol and a surprising amount of fat.

Then why does everyone who is working out say to eat egg whites? Nutrition is tough to get a handle on cause there are so many different suggestions. The main is reason is that the yolk does contain some bad cholesterol. It also contains some good cholesterol, but of course you want to try and limit the bad as well. Which is why I said 2-3 a day won't hurt you. Any more than that and you are over doing it in regards to the bad cholesterol Another problem with this is that most people don't understand how your body works. Most bad cholesterol that you eat passes right through you, unless you also eat a large amount of fat with the eggs (bacon). In that case the cholesterol binds with the fat in your stomach, and then the fat carries it to your blood in which case the cholesterol gets caught in your arteries. In conclusion, don't eat more than two or three egg yolks at a time and avoid fat when you eat them and they are one of the most nutrient rich foods you can eat. |

I don't know what the websites say but I know that the ph of the yolk is lower than the white because it contains more amino acids. The only thing I can think of is that maybe the white contains more complete proteins, but other than that they are dead wrong. |

No, that is exactly right. The white contains a lot more complete proteins.
Also, the level of protein in the yolk isn't enough to offset the fat content, and the bad cholesterol. Also, incomplete proteins do not help gain muscle mass because they do not have all the necessary amino acids to build muscle mass.
There may be more amino acids in the yolk, but not the ones necessary to develop complete proteins which in turn develops muscle mass.
hence, the white is the most popular form of protein there is out there.

There may be more amino acids in the yolk, but not the ones necessary to develop complete proteins which in turn develops muscle mass. hence, the white is the most popular form of protein there is out there. I think we are kind of arguing two different points here, but let me clarify mine a little bit. I was simply saying that the idea that most of the proteins in an egg are in the white is false. The yolk contains way more protein including more limiting amino acids, or the amino acids that are the foundation for building other amino acids. With out your limiting amino acids you can't build more complex ones. But as we have both said the white only contains protein and water, so if you just want protein for building muscle and nothing else then eating the white only is the way to go. If however you are eating the egg for health benefits then it's better to eat both the white and the yolk so that you get the full amount of nutrients from the food. But like with many other things the key is to not over do it. Just because eating 2 eggs is healthy doesn't mean eating 8 eggs is healthy. In that case you are eating too much bad cholesterol. |

I agree with that.
Again, the only disagreement is that you say the yolk has more protein. The average egg has 6.3 grams of proteins. Of theat 6.3 grams, 3.7 comes from the white and 2.6 comes from the yolk.
The other side of my argument for the "just white" part of the egg: An egg has 70 calories, 5 grams of fat, and 215 mg of cholesterol (the recommended daily amount of cholesterol is just under 300 mg).
Of the 70 calories, 53 are in the yolk
All 5 grams of fat are in the yolk
All the cholesterol is in the yolk
Like Finch said, eating one or two is healthy. But when eating an egg for a source of protein, you should bypass the yolk.

but, its what we do.
See, between the two of us, now all of y'all know about the nutritional value of eggs. You're welcome.

Amazing that we can have a 3-4 page discussion about pretty much anything. If devoted as much time to school as I do to arguing on this board I would have a 4.0.
