Are you one of the people that swears by egg whites or avoids eggs altogether? Scared that the yolk is high in cholesterol and bad for your heart? Although this is partially true, by tossing the yolks you’re missing out on one of the most nutritious, healthy, and beneficial foods available. What’s even more promising is that more and more research is beginning to show that cholesterol from animal sources may no longer be detrimental to cholesterol levels, but in fact may actually help improve blood lipid ratios. Yolks are also jam packed with heart-healthy omega-3 and omega-6 fatty acids which further benefit cholesterol levels.

Egg Yolk
Yolks exclusively contain the antioxidant vitamins A and E, as well as two powerful carotenoids lutein and zeaxanthin. These nutrients help fight nasty free radicals which are responsible for causing over 60 health conditions, including cancer and premature aging. Yolks also house all of the omega-3 and omega-6 fatty acid content.

Additionally, yolks house over 80% of the daily required amounts of zinc, choline, vitamin B6, folate, iron, phosphorus, calcium, niacin, and pantothenic acid. All of these vitamins and minerals are essential to good health and responsible for the proper functioning of the body. Iron, zinc, and calcium deficiencies are highly prevalent worldwide in different populations, simply eating egg yolks could help fix these issues.

The only nutrients in which the white contributes significantly higher amounts than the yolk are sodium, magnesium, and potassium–electrolytes abundant due to the egg white’s high water content. Other than electrolytes, the whites are largely devoid of nutrients.

The Bottom Line

Start adding yolks back to your diet. By skipping the yolk you’re cheating yourself out of one of the world’s best nutritional powerhouses.
