While on the topic of eggs, I’m hoping you guys can help me with something.
I have high cholesterol inherited from both of my parents. The doctor (general practitioner) told me to cut down on certain foods, eggs being one of them. Now, I know that consuming high cholesterol foods does not mean blood cholesterol will rise. But that doctor is still in the back on my mind whispering that I should cut back on the eggs. The doctor also gave me some list with a bunch of things I should stay away from. It looked like something copied from the pages of a 1980s textbook.
So is this doctor most likely out of touch with recent nutrition studies and the eggs will be fine?
What are your thoughts on eating egg whites only and getting rid of those cholesterol filled yolks?[/quote]
I think it bears repeating that high cholesterol does not cause heart disease, nor any other disease for that matter. Except for very rare genetic disorders, high cholesterol is not a marker for anything. All that was found was a very dubious correlation between cholesterol levels and heart disease. However, those early studies omitted several points of data would refute the hypothesis. Furthermore, 20 years of treating cholesterol numbers has done nothing to alleviate heart disease. Statins have been found to be wholly ineffective in combating heart disease and have actually shown to cause higher mortality.
When your doctor measures your cholesterol numbers, he is actually measuring the amount of lipoproteins in your blood. Lipoproteins come in two flavors, high density and low density, based on how they seperate in an ultracentrifuge. That’s where the term LDL and HDL come from. Now, here’s something truly damning. LDL and HDL are both good “cholesterol”. There were several drugs in Phase 3 clinical trials that raised HDL numbers, their only side affect was that they made you more likely to die from all types of mortality.
The only true enemy is small, dense LDL, which is not measured in any conventional tests. These lipoproteins are very easily oxidized and activate your body’s inflammation response. The best way to control their production is through controlling their production, which is through triglyceride intermediates. This can be accomplished by stress reduction, inflammation control (eg omega-3s, antioxidant intake, eliminate starchy carbs, insulin sensitivity) and elimination of processed, oxidized fatty acids (basically anything commercially made) Avoiding processed oils is the single healthiest thing you can do. Even if something says that it does not have trans fat, it still will have high levels of oxidized oils, due to the nature of processing. And now, more and more companies have switched to inter-esterified oils, which are supposedly worse than trans fat.
Secondly, insulin strongly drives LDL/HDL production. If you have a strong insulin response in the presence of the aforementioned fatty acids, you will produce small, dense LDLs. This is why it’s crucial to control your insulin response as much as possible. Excess insulin and carbs also contribute to the very same triglyceride intermediates that drive production of all lipoproteins.
Finally, on topic, studies have shown that consuming eggs actually improves all your blood lipid numbers. Yolks are among the healthiest foods you can eat. It’s full of good fats, vitamins, minerals and micronutrients. Remember, it’s a complete source of nutrients for a growing chick.
