Egg Yolk Health Benefits and Nutrition Facts

Nutritional summary

Egg yolks are a primary source of dietary cholesterol, yet current institutional guidance has largely removed strict daily limits because dietary cholesterol has a relatively weak impact on blood cholesterol levels for most people .
The fats in egg yolks are predominantly unsaturated, consisting of monounsaturated and polyunsaturated fatty acids that are considered more heart-healthy than saturated fats .
Egg yolks contain lutein and zeaxanthin (carotenoid pigments), which are highly bioavailable and are well-established for supporting eye health by reducing the risk of cataracts and age-related macular degeneration .
Multiple large-scale meta-analyses and systematic reviews indicate that consuming up to one egg per day is not associated with an increased risk of cardiovascular disease in the general population .
Egg yolks are a significant source of phospholipids and choline, which are essential components for maintaining cell membrane structure and supporting metabolic processes .

Interesting fact

The vibrant color of an egg yolk is determined entirely by the hen's diet, specifically the levels of carotenoid pigments found in the plants or insects she consumes.
