The egg

[bronson]

This subject came up on another board. A discussion on eating the yolk of an egg or not. This is a post I put up on eggs. Do you think eggs get a bad rap ? Read this first then decide.




Ok. Here is some egg fact research! An EGGSACT science!



Much Cholesterol To Diet

Nutrition researchers at Kansas State University have published the first evidence that the absorption of cholesterol is reduced by another compound in the egg, a lecithin.
The research by Sung I. Koo, Yonghzhi Jiang and Sang K. Noh has resulted in the issue of U.S. Patent No. 6,248,728, "Compositions and methods for lowering intestinal absorption and plasma levels of cholesterol." The patent was issued June 19 to the KSU Foundation.

A peer-reviewed research paper by the three researchers, "Egg phosphatidylcholine decreases the lymphatic absorption of cholesterol in rats," appears in the September issue of Journal of Nutrition.

Many people believe that dietary cholesterol directly contributes to raising blood cholesterol. Because eggs provide about half the dietary cholesterol in a typical Western diet, the public has been advised to limit its egg consumption.

Under the experimental conditions using an animal model that closely mimics human physiology, Koo and his associates found that a particular egg phospholipid interferes with the absorption of egg cholesterol and markedly lowers its uptake by the intestine. When the phospholipid is saturated, its inhibitory effect is further enhanced.

The researchers controlled experimental conditions to specifically look at egg phospholipid and its effect on cholesterol absorption. Even though a good amount of cholesterol is consumed when an egg is eaten, much of the cholesterol becomes "unavailable for absorption" in the presence of the phospholipid, Koo said.

"This may be a reason why so many studies found no association between egg intake and blood cholesterol," he said. The phospholipid, or lecithin, found in egg markedly inhibits the cholesterol absorption. The inhibition is not 100 percent, he said. Some cholesterol is absorbed but the amount is significantly reduced in the presence of this phospholipid.

"Less absorption means less cholesterol introduced into the blood," Koo said. "We were able to determine experimentally that a substantial amount of the egg cholesterol is not going into the blood stream."

Koo says people with normal cholesterol levels and no family history of cardiovascular disease should not worry about eating one to two eggs a day. There's more overall nutritional benefit than harm to be gained from eating "nutrient-dense" eggs -- in moderation, he said.

Egg contains a higher quality protein than protein found in meat, milk or fish.

Furthermore, egg is a significant source of vitamins A and E, and B vitamins B-6, B-12 and folate, which are known to lower blood levels of homocysteine, an independent risk factor for heart disease.

Koo's research has received support from the Kansas Agricultural Experiment Station and the USDA National Research Initiative Competitive Grants Program.

Koo is a professor of human nutrition at K-State; Jiang received a master's degree in nutrition from K-State; and Noh is a postdoctoral researcher at K-State who is continuing research with Koo. - By Kay Garrett

From the posts I have read on the other board, it seems that most will try to avoid saturated fats, but are going to eat the complete egg.

Interesting read. I always eat egg whites, but will keep on eye out for continued research on this topic. To be honest I like the taste of egg whites and don't miss the yolk....maybe that's why it's so easy to avoid them.

I thik they do get a worse rap than they deserve. However, the average american eats way too much fat, so cutting out a few egg yolks might not be a bad idea. I personally don't eat them because I try to keep my overall fat intake down to a certain level.

Yunz probably think I am egg crazy. Read some more on eggs. Eggs are cool!

*Looks up from huge Elvis plate of eggs and oatmeal and gives thumbs up!

I have to keep the yolk, I can put up with the white, just.

[Jonathan]

I fully understand.
I just recently was able to begin not including the yolks in my 4 eggs per morning....It wasnt very good at the first but Ive found there are lots of calorie free ways to spice things up.Also like most other healthy food that has no fat (meaning less flavor) you will get used to it and be able to enjoy it.IE:drinking only water killed me at first,so I started with Fruit 2o,its zero calories but $$,now im able to just do bottled water alone.Also Cottage cheese (fat free kind) took a while to be able to enjoy,but now I really can say I look forward to it.
I am an Executive Chef,I know and love food.So if I can do it anyone can...Goodluck!

p.s. Someone posted one time "Every bite you take is one step closer to or further from your goals."

I buy Crystal Light in bulk for this very reason! Plain water gets old about 2:00 for me.

Add some flax seed to your cottage cheese as well. Adds in healthy fats and is heart-healthy.
