Are Eggs Bad for You?

Demonizing eggs seems to occur on a regular cycle. So what’s the deal with eggs and are egg yolks bad for humans?

To answer this question, let’s take a look at cholesterol, because it’s the bad actor everyone blames for blocking arteries and causing heart attacks and strokes. Nearly all of the cholesterol in your body is made by your liver, and in fact, the most popular cholesterol-lowering drugs work by reducing your body’s production of cholesterol in the liver.

Even if you do NOT eat cholesterol, your body will make it on its own, because you can’t live without it! Plus, for most people, dietary cholesterol intake has little to no effect on your blood cholesterol levels, and so do egg yolks!

As previously reported by NPR:

†[E]eating cholesterol can raise its levels in the blood, but, as a growing body of research has shown, not by much. Consuming sugar, trans fats or excessive saturated fat (from unhealthy sources) can be more harmful to cholesterol levels than dietary cholesterol itself.

We make most of the cholesterol in our bodies ourselves in the liver, and the total body level is strongly influenced by genetics, gender and age. As more and more research suggests that some level of cholesterol consumption is harmless, if not healthy, the egg’s reputation is gradually returning.”

In 2015, dietary cholesterol (and egg restriction) was finally eliminated from US dietary guidelines, and the controversy appeared to have settled. However, there always seems to be another study urging people to avoid eggs, linking egg consumption and dietary cholesterol to an increased risk of cardiovascular disease and death.”

An example of an investigation into defective eggs

A study, published in the journal JAMA on March 19, 2019, analyzed data from 29,615 U.S. adults collected from six prospective cohort studies with a median follow-up of 17.5 years, and claims to have found a dose-dependent relationship between egg consumption and cardiovascular disease. cardiovascular disease (CVD) and all-cause mortality.

According to lead researcher Wenze Zhong, Ph.D., the results suggest there is no safe amount of egg consumption, and the team believes the results should be considered when U.S. dietary guidelines are updated.

Big problems with this egg study

A careful review shows that these are the multiple major flaws of this study.

According to Stuart Phillips, Ph.D., director of the McMaster Center for Nutrition, Exercise, and Health Research — the amount of risk reported in the study is trivial because the actual change in risk is insignificant. For example, they mention a relative risk increase that is very deceptive. The study mentions a relative risk increase of 17%. However, the absolute risk (that’s all that matters!) paints a very different picture and corresponds to 17 versus 15 coronary events (2 events in total) per 1,000 person-years. Needless to say, this difference is meaningless.

It’s also important to note that their data is based on individuals’ memory of what they ate, which has been shown to be highly inaccurate time and again.

Andrew Mente, Ph.D., principal investigator of the Epidemiology Program at the Population Health Research Institute, pointed out another problem with the data from this study:

“The primary hypothesis here is that eggs raise your bad cholesterol, and the more you eat, the worse it gets. But hidden deep in the appendix is ​​a note that they found that a higher egg intake is linked to a lowering of cholesterol. LDL, your bad cholesterol So, what’s driving the association in this study? It seems like there’s a contradiction with the findings.”

Several studies have confirmed that eggs are good for your heart

There have been several large meta-analyses that have completely disproved the claim that egg consumption increases your risk of CVD.

Choline – an essential nutrient found in egg yolk

Another common misconception is that egg yolks are bad. In fact, the yolks contain all the micronutrients (proteins are an excellent source of highly bioavailable proteins, but almost no micronutrients).

In addition to cholesterol, egg yolks contain several important micronutrients. Yolks, for example, contain vitamins A, D, E and K along with omega-3 fatty acids. Egg yolks also contain more beneficial folic acid and vitamin B12. The yolks also contain much more of the nutrient choline than the proteins, and all of the antioxidants lutein and zeaxanthin which are essential for eye health.

Choline is an essential nutrient that you MUST consume to produce Acetylcholine, a primary neurotransmitter. Can’t get enough and you can’t make enough Acetylcholine and that is NOT a place you want to go!

Acetylcholine is essential for brain, nerve and muscle function and is also essential for the liver. Egg yolks are by far the best food source for choline!

So don’t be so quick to throw away your eggs – a highly nutritious, high-protein food that isn’t too expensive!
