A chicken egg has between 6 and 7 grams of protein. This is because the amount of protein in an egg depends on the type of food the hen eats and the size of the egg, for example.
Quail eggs, despite being smaller, have around 5 grams of protein.
There are many other sources of animal and plant proteins, such as meat, fish, beans, chickpeas, and flax and sesame seeds. It is important to have a varied diet to ensure good health.
