Ok, so it's very common for people to throw out their egg yolks because they're afraid of a little cholesterol. I want to rip out my hair every time i see a yolk hit the garbage. The yolk of an egg is EXTREMELY nutrient-dense. Why would you throw out vitamins?
The most common reason people throw out the yolks is because of the cholesterol. And I agree that egg yolks are very high in cholesterol. However, there are 2 different kinds of cholesterol:
LDL-Low-density lipoproteins(Bad cholesterol)
HDL-High-density lipoproteins(Good cholesterol)
There have been multiple studies where some people ate eggs every morning, and some people ate some kind of generic breakfast like cereal, or bagels, etc.
In all of the studies, the people who ate eggs hardly experienced a rise in there LDL, but there HDL experienced a significant rise. So again, PLEASE DONT THROW OUT THE EGG YOLKS!!!!!!
