Egg yolks are rich in lipids, vitamins, minerals and proteins. High in both saturated and unsaturated fats, egg yolks contain beneficial fatty acids such as oleic acid and linoleic acid.
Egg yolks are also a very good source of lecithin, which is a source of choline, and essential for the healthy metabolism of fats. The yellow colour of egg yolks comes from the carotenoids lutein and zeaxanthin, which are known to be beneficial to eye health and helpful in the avoidance of macular degeneration.
The powder is made from spray dried egg yolks, and egg yolk powder is a popular addition to protein shakes and smoothies, particularly for people who are trying to add weight. If you don't like the taste of eggs, but want to add the benefits of eggs to your diet, egg yolk powder is a good option.
A natural source of vitamin D, egg yolks can also have cardio-protective properties. Yes, they do contain cholesterol, but they also contain phospholipids which can help to lower blood pressure and reduce inflammation.
