The nutrient levels of eggs have been the subject of debate among nutritionists for the longest time. The fact that eggs are laid for the sole purpose of creating life means that eggs naturally contain high levels of nutrients. Whole eggs are rich in iron, vitamin A and B, phosphorus, and loads of high-quality protein. However, nutritionists often caution against daily egg consumption due to their high cholesterol quantities. Regular egg consumption is still recommended if you plan on minimizing the risk of diabetes and heart disease.
