Why do health experts say that yolks are nutritious but recommended eating them in moderation?

Health experts consider egg yolks nutritious because they are rich in essential vitamins, minerals, and healthy fats, providing key nutrients like vitamin D, choline, and antioxidants. However, they also contain dietary cholesterol and saturated fat, which can impact heart health when consumed in excess. Thus, moderation is recommended to balance the benefits while minimizing potential risks associated with high cholesterol intake.
