I was sort of shocked at an article I read from fitness guru Tom Venuto. He was talking the late bodybuilder, Vince Gironda, whom he bases his fitness principles on. One part in particular is speaking on eggs. In a nut shell, he is saying that eggs are the best sources of protein. Not egg whites....whole eggs! He breaks it down explaining that egg whites are the protein, and the yolk is the fat. He says you can't digest the protein properly if you take out the fat. He goes on to say that eggs are the finest protein source, along with liver and milk. They have the highest protein efficiency ratio. It goes on to say that when you seperate the white and the yolk, you get an isolated protein. For ex:, if you eat an egg white, it goes into your stomach, and your stomach says, "hey where's the fat!" The white which is protein, has no vehicle for conversion, so it's converted to sugar. The same thing happens when you use protein powder. They say mix it with juice or water because they're made of ionized whey protein, which is the skim of cottage cheese. It's not biologically superior to eggs, liver and milk. The powders make you feel good because they are carbohydrated sugar. You put on weight, but it's not going to be muscle weight. Again, you can't digest protein without fat, and it must be digested to be converted to amino acids. Once it's digested it goes through the liver and is converted to amino acids. He also says eggs don't cause heart attacks. He states they closely match the human anatomy, and it's all the processed foods, that cause them. He says, God is the greatest chemist in the world! Hmmmm......that is something to digest! Ha..LOL:)

Very interesting. I have never believed eggs were bad for you, in moderation. I love eggs yoke and all. I haven't read the article, but I will. I don't know about the protein, fat combonation. Do you think it's true? In the meantime, I think I'll stick to just the whites. How's you new calorie intake coming and your cutting phase?

I haven't started it yet. I am in 2 weeks. I think just as anything else, we live in a society that makes us believe certain things, that aren't neccessarily true. We aren't not always open to different things. I for one, pretty much believe stuff that has a a good medical backing. I believe the article in it's entirety. The simple answer as to whether eggs are good or bad for us, is no. How can they be. They are a natural food. I bet you will still be skeptical. :)

I do not find this unbelievable since almost every weekday morning I have at least one scrambled egg (whole egg). I have been doing this since I started this weight loss journey in September. My physical last year, before my weight loss journey began, indicated that my cholesterol was high (234). In March I had another physical and this time my cholesterol was well within the normal range (173). If whole eggs were as bad as people thought, I think my cholesterol level would have remained unchanged (especially with me eating eggs every morning). I had read an article in Prevention some time ago saying that eggs were not as bad as doctors once thought but could be bad for people with serious heart problems or something to that effect.

One more thing...remember when they were saying that shrimp were bad for you. Even now my mom tells me to stop eating so much shrimp b/c it will increase my cholesterol. I printed out an article for her to read but she being old and stubborn still wanted to believe the old way.

The only part I'm skeptical about is that your body needs the fat to digest the protein, not that eggs are good or bad. I don't think they are bad and never have. Lot's of people in the medical field have different opinions on different things and those opnions change over time. Fist caffein in bad then it's good, alcohol is bad then it's good, etc..etc...I read an article not too long ago that said that eggs were not as bad as everyone first thought. My theroy is if you wait long enough, the things that you were told are bad, end up not being bad at all. :)

Gee, reading that makes me wonder if my old biochemistry and cellular biology professors know they wasted a good chunk of their careers teaching the biochemical mechanics of food digestion/breakdown/processing.
Honestly, you cannot beleive everything you read.

Sorry, let me clarify my last post...
I was referring to the mention of the body requiring fat to digest protein, not that eggs are not bad for you. protein and fat are two different chemical compounds, requiring different enzymes and digestive processes to breakdown. The human body does require specific proteins and fats to help produce some enzymes, but these enzymes take time to build from their basic building blocks - they don't instantly form themselves out of what finds its way into your stomach at any given time.
Just about everything is good for you, in moderation, just as almost everything is bad for you if overconsumed. Egg yolks have a high amount of cholesterol. Too many eggs, coupled with lack of activity can contribute to elevated cholesterol levels. Eggs in moderation generally won't. Cutting back on cholesterol-containing foods is one part of lowering cholesterol (and eggs aren't the only high-cholesterol foods out there either so you can cut back on everything but your eggs and be ok if you wanted to)
I have an egg white omlet with half a dry toasted bagel for breakfast almost every morning and I have no digestive problems with that. I guess it depends on your body and what you are used to. I actually prefer the egg whites to teh whole eggs, a I now find a full egg omlet too heavy.
Cheers,
Niki

Yeah, reading anything since being able to read, makes me wonder. As for whether a whole egg is okay to eat, is pretty simple. Eggs are a natural food. Are we to question God, in whether an egg is good or not.

The article was not breaking down how fat and protein are digested. It is saying that you need fat to digest protein. If you don't have fat with protein, the protein is an isolated protein, and is converted to sugar. It says that protein must be digested, to be convereted to an amino acid, and the only way you can digest protein, is with fat. That is true. Ask anyone who truely knows anything about protein.

You are lucky you caught me on a morning when I have plenty of time..
The following is an excerpt from Chapter 24 (The Digestive System) of _The Prinicipals of Anatomy and Physiology_, 5th Edition. By Gerald Tortora & Nicholas Anagnostakos, pages 605-606 (1987). This is a university text used extensively for anatomy courses as well as nursing courses.
****
Digestion in the stomach - Chemical
"The principal chemical activity of the stomach is to begin the digestion of proteins. In the adult, digestion is achieved primarily through the enzyme pepsin. Pepsin breaks certain pepside bonds between the amino acids making up proteins. Thus a protein chain of many amino acids is broken down into smaller fragments called peptides. Pepsin is most effective in the very acidic environment of the stomach (pH 2). It becomes inactive in an alkaline environment."
...[the next chapter discusses the formation of pepsin and how it is kept from digestng the stomach walls, not relevant to my point, I will carry on with the 3rd paragraph]...
"Another enzyme of the stomach is gastric lipase. Gastric lipase splits the butterfat molecules found in milk. This enzyme operates best at a pH of 5-6 and has a limited role in the adult stomach. Adults rely almost exclusively on an enzyme secreted by the pancreas into the small intestine to digest fats."
*****
To sum up, proteins are broken down into amino acids in the stomach, fats are broken down (into fatty acids and monoglycerides) in the small intestine. Amino acids are absorbed into the blood stream in the small intestine. Long chain fatty acids and monoglycerides are absorbed into the lymphatic system in the small intestine (short chain fatty acids absorb into the bloodstream) (pages 618-621). Neither protein nor amino acids are dependant on fat molecules for digestion.
Also, protein, by definition is made of amino acids. No sugars/carbohydrates involved.
Again, eggs are fine if consumed in moderation, but the statement that you need fat to digest protein is hooey.
but thanks for giving me the brain exercise this morning :-)

I disagree with this...u need fat in your diet basically but that doesnt mean if u have a whey protein shake (often with near 0 carbs and a fake sugar for sweetning) without fat it doesnt mean it wont be able to digest...otherwise everytime we have a shake we have to have fat with it? no way..otherwise thats alot more cals people have to factor into their diet just to get protein...there wouldnt be too many skinny people and if there were, they arent getting enough protein!! lol...wouldnt it be funny to see a bodybuilder have a shake with a snickers bar?...it doesnt convert to sugar (glucose) unless you have hardly any glucose in your body to begin with...your body will carry out its functions first, build muscle second (the latter is not a priority for the body)...so if you eat stuff all carbs, then yeah some of that protein may go to this but generally speaking, it wont...
Your right about protein - milk and liver and eggs have a high biological value....if you can stomach liver then your on a good thing with protein especially...however its the quantites...a glass of milk will give you only so much..lets say 9 grams for example...a whey shake, a derivative from milk (the good part!) will give you 30 grams a serve....so i would take the whey any day...also an egg has about 15 cals in the egg white and is pure protein...but only therefore about 4 grams of actual protein...to say u have to eat the yolk (combined to make 75 odd cals) with the white just to digest protein is really something a pro shouldnt be feeding the general population.

Well fat is meant to be in the diet. You just need to make allowances for it like anything else. Balance your macronutrients. It is possible to take fat with every meal if you measure it carefully. I take over 500 calories a day in fat at times. You just need to reduce the carbs when you do it. A no fat diet or very low fat diet is not good for you anyway.
