Eggs have been an ubiquitous food for humans throughout history. People all over the world eat eggs without getting worried about its actual nutritional value.

The proteins that eggs contain is one of the highest quality protein on the supplemental shelves. It has a high BV (biological value) and boasts a great amino-acid profile including a high amount of sulfur containing amino acids that is critical to the body's hormone-producing pathways.

So what about cholesterol? The good news is that the cholesterol in eggs has no effect on blood cholesterol levels of a healthy person. However, people with diabetes, high cholesterol levels, or heart diseases have shown some increase in the cholesterol levels due to eggs. Cholesterol is very important for our body as it is the structural molecule for every cell membrane to make hormones like testosterone, estrogen, and cortisol. Liver produces cholesterol but if we eat a cholesterol-rich food the liver starts producing less.
Egg whites have no cholesterol. It's only the yolk that contains cholesterol. A large egg has 186 mg cholesterol only in the yolks which is 62% of daily intake recommended. Daily intake of cholesterol for a healthy person in 300 mg and for people with diabetes, high cholesterol, and heart diseases the recommended intake is 200 mg.
