Amino Acids composition of egg-whites compared to amino acid composition of ideal pre-physical-activity and post-physical activity meals, reveals Egg-whites as a post-physical-activity food.
 
Problem of devising a quantitative measure of to what extent a food's amino acid composition is post-workout, pre-workout, or neutral solved
 
Previously I had concluded based on how egg-whites rank compared to other foods with regards to lysine-leucine-glycine (emphasized in projected ideal pre-workout meal) and with regards to tyrosine-threonine-serine (emphasized in projected ideal post-workout meal) that egg-whites are a post-workout meal (http://coolname001.angelfire.com/eggsforlunch.htm).
 
Does such continue to hold up as valid if egg-whites are subjected to a more detailed amino acid analysis? Even if egg whites are low in lysine-leucine-glycine and high in tyrosine-threonine-serine, they could still end up in the end turning out to be actually a pre-workout food, because 20 amino acids are involved not just 6. So what is the verdict, was I right to estimate that eggs are a post-workout food? Answer: yes.
 
The table below on this page shows what the percentages and mgs for various amino acids are in my estimation for: ideal general meal regardless of pre-workout or post-workout considerations; ideal post-workout meal; and ideal pre-workout meal.
 
The table shows what the percentages and mgs for various amino acids are in egg-white. It shows the average of the percentage for the pre-workout meal and the percentage for the post-workout meal which is the same as the estimate for meals in general regardless of pre or post workout.
 
The table shows how the percentage weight occurrence of an amino acid in egg white compared to amino acids in general in egg-white (as total 100%), compares to ideal percentage occurrences of the amino acid for the general, pre-workout, and post-workout diets.
 
So looking at egg-white amino acids turned out to be like watching a cricket game. Would the end result be, that egg-white would be revealed to be indeed a post-workout food as I had suspected, or would the end result be that it is a pre-workout food?
 
And how would I solve the headache problem of being able to quantify to what extent egg-white is pre-workout or post-workout or neutral in terms of when it should be consumed in relation to a physical activity?
 
The idea has been that egg-whites are a post-workout food, because in egg-whites, the ratio of lysine-leucine-glycine (desired for pre-workout) to tyrosine threonine serine (desired for post workout) is unusually low, meaning that although this ratio is 1.17, higher than 1 with egg-whites, egg-whites should be classified as a post-workout food because the 1.17 ratio number is relatively low.
 
Lysine, Leucine, and Glycine are all represented more highly in the pre-workout diet than they are in the post-workout diet. The Lysine, Leucine and Glycine percentages in egg-whites as it turns out, are all closer to the post-workout diet levels than they are to the pre-workout diet levels. With Lysine Leucine and Glycine, egg whites do a good job of keeping their percentage compared to other amino acids in egg whites down to a level at which the egg-whites percentages resemble that found in the post-workout diet more than they resemble that found in the pre-workout diet.
 
Threonine and Tyrosine are represented at higher levels in the post-workout diet than they are in the pre-workout diet. Their presence relative to other amino acids in egg white is such that their fractional presence compared to other amino acids in egg whites resembles the pre-workout diet projected ideal more than it does the post-workout diet projected ideal.
 
Serine is represented at a higher level in the post-workout diet than it is in the pre-workout diet. The fraction of amino acids in egg whites that is Serine, more closely resembles the post-workout projected ideal serine fraction than it does the pre-workout projected ideal serine fraction.
 
Looking at other amino acids, Glutamic acid, for example, batting for the "egg-whites are actually a pre-workout food" team, did alot to put up numbers indicating that actually egg-whites are a pre-workout food.
 
The projected ideal for the post-workout meal glutamic acid percentage is 4.9% of all amino acids;  in egg-whites glutamic acid is 8.0% of the amino acids; in the projected ideal pre-workout meal glutamic acid is 9.3% of all the amino acids. According to my scoring the glutamic acid percentage in egg white, by being such a big part of egg white, combined with being so much closer to the pre-workout ideal as compared to the post-workout ideal, put up big numbers in support of the idea that egg-white is actually a pre-workout food.
 
But in the end, my scoring had the contest as at 37308 (57%) post-workout, 25625 (39%) pre-workout,  2900 (4%) neutral; meaning that I classify egg-whites as 57-39-4 on the post-workout/pre-workout/neutral scale, and as a post-workout food.
 
The scoring was done by assigning an amino acid in egg-white a number as scoring for either the "egg whites are a pre workout food" or the "egg whites are a post-workout food" team; if the percentage representation of an amino acid in egg-white was closer to the pre-workout ideal, the runs were scored for the pre-workout team, and the number of runs scored depended upon a combination of how important the amino acid doing the batting is in egg-whites, combined with where on the scale of ideal percentage representation in pre-workout meal compared to ideal representation in post-workout meal, the percentage representation of an amino acid in egg whites is located.
 
Basically the reverse was done if the percentage representation in egg whites was closer to the post-workout ideal than it was to the pre-workout ideal. See 2nd stat in rows C and F.
