The primary nutrient found in eggs is protein. Eggs are considered one of the most complete sources of protein because they contain all nine essential amino acids that the body cannot produce on its own. The protein content in eggs is highly bioavailable, meaning it is easily absorbed and utilized by the body. Additionally, eggs provide essential vitamins and minerals such as vitamin B12, riboflavin, and selenium. They also contain healthy fats, especially in the yolk, making them a nutritious whole food. This combination of nutrients makes eggs a valuable part of a balanced diet.
