Are Whole Eggs And Egg Yolks Good Or Bad For You?.

Depending on whom you ask, whole eggs are either incredibly nutritious or harmful for your health.

On one hand, they’re considered an excellent and inexpensive source of protein and various nutrients. On the other hand, some people believe the yolks can increase your risk of heart disease.

So, are eggs beneficial or harmful for your health? This article explores both sides of the argument.

Why are eggs sometimes considered unhealthy?

Whole eggs have two main components:

• Egg white:the white part, which is mostly protein
• Egg yolk:the yellow or orange part, which is rich in nutrients

The main reason eggs were considered unhealthy in the past is that the yolks are high in cholesterol.

Cholesterol is a waxy substance found in food. It’s also made by your body. A few decades ago, large studies linked high blood cholesterol to heart disease.

In 1961, the American Heart Association recommended limiting dietary cholesterol. Many other international health organizations did the same.

Over the next several decades, worldwide egg consumption decreased significantly. Many people replaced eggs with cholesterol-free egg substitutes that were promoted as a healthier option.

How eating eggs affects blood cholesterol.

Although it may seem logical that dietary cholesterol would raise blood cholesterol levels, it usually doesn’t work that way.

Your liver actually produces cholesterol in large amounts because cholesterol is a necessary nutrient for your cells.

When you eat larger amounts of high cholesterol foods, such as eggs, your liver produces less cholesterol because more of it is coming from your diet.

Conversely, when you get little cholesterol from food, your liver produces more to compensate.

Because of this, blood cholesterol levels don’t change significantly in most people when they eat more cholesterol from foods.

In one long-term, well-designed study, consuming egg yolks daily for 1 year did not significantly change total cholesterol, LDL (bad) or HDL cholesterol, or the ratio of total cholesterol to HDL (an important marker of heart disease) in adults with early signs of age-related macular degeneration.

However, one review of well-designed studies in healthy individuals found that eating cholesterol-containing foods raised both LDL (bad) and HDL cholesterol, but the ratio of LDL to HDL (an important marker of heart disease risk) remained constant compared with the control group.

Likewise, in another study, 30 people who ate 3 eggs per day for 13 weeks had higher total cholesterol, HDL, and LDL (bad) cholesterol compared with those who took only a choline supplement.

However, their HDL to LDL ratio remained the same. The study’s authors concluded that eating foods high in cholesterol regulates the amount of cholesterol your body makes in order to maintain the HDL to LDL ratio.

Also, keep in mind that cholesterol isn’t a “bad” substance. It is actually involved in various processes in your body, such as:

• production of vitamin D
• production of steroid hormones like estrogen, progesterone, and testosterone
• production of bile acids, which help digest fat

Last but not least, cholesterol is an essential component of every cell membrane in your body, making it necessary for survival.
