If you are going to have eggs, then be sure you are having the healthy kind. There is a way to figure out which is which.
A useful way to gauge how healthy and nutritious your eggs are is to tale a look at the colour of the yolk. Evidently, the darker the colour, the happier the chicken that laid it was and the better quality its feed. This means the eggs will be of good quality.
Scientists discovered that the colour of an egg yolk is determined by something called carotenoids. The higher level of carotenoids the egg has, the more orange the yolk is.
Carotenoids are also an indication of vitamins so the deeper the colour, the healthier the egg is.
