FACT CHECKED BY Olivia Tarantino

Eating eggs means you might be getting an ample amount of protein added to your diet. This is great to help rebuild your body, and can potentially help you develop muscles. Not to mention, eggs may help you with your overall body health, such as potentially losing fat and lowering inflammation levels. There's a lot that can be done by incorporating this small food.

However, while the egg as a whole can be great, both egg whites and egg yolk can have different effects on your health. Looking to separate the egg yolks from the egg whites?

"Egg yolks contain the phytochemical lutein, which is also what gives the yolk that gorgeous yellow hue," says Amidor.

According to Amidor, lutein has been linked with eye health. Specifically, lutein has been connected to preventing macular degeneration—the cause of vision loss, which may occur as you age.

They give you muscle-building protein.

"The yolk contains almost half the protein in the entire egg," says Amidor.

Generally speaking, a whole egg is rich with nearly 13% protein. If you're eating one extra-large egg that consists of 7 grams of protein, 3 of those grams would belong to the egg yolk.

"Protein helps with a variety of functions, including building muscles, so don't toss those golden yolks," Amidor exclaims.

They may help heart health.

Amidor suggests that the yolk also provides omega-3 fats, which have been shown to help promote heart health and reduce the risk of dying from heart disease.

Certain omega-3 fats have also been linked to potentially killing cancer cells and may help with arthritis.

"The egg yolk is one of the only food sources of vitamin D," says Amidor. "Vitamin D helps calcium get absorbed—and both help keep your bones healthy."

Amidor further suggests that it's important for both children and adults to get enough of this nutrient to prevent the risk of bone diseases. This includes rickets in children and osteoporosis in adults.

"In addition, vitamin D is one of the under-consumer nutrients in every population as per the 2020-2025 dietary guidelines for Americans," says Amidor.
