Currently, there is a wide variety of eggs, including chicken, duck, goose, quail, and pigeon eggs. Experts believe that the protein content of various types of eggs is similar, accounting for about 12% of the entire egg. For example, a chicken egg contains 6-7 grams of protein. The amino acid composition of egg protein is the closest to human needs, superior to other animal proteins, and thus has very high nutritional value.
However, when eating eggs, only eating the egg white and not the yolk is not necessarily "taking the essence and removing the dross." This is because the nutritional value of the yolk is far higher than that of the egg white.
This is because the main component of the egg white is protein, with very little content of other nutrients. The yolk, on the other hand, is rich in a wide variety of vitamins and minerals, and its protein content is also higher than that of the egg white. Additionally, the yolk is indeed an excellent source of phospholipids. Phospholipids have the effect of lowering blood cholesterol and can promote the absorption of fat-soluble vitamins.
As for the high cholesterol content in egg yolks that many people worry about, or the idea that "eating a yolk is equivalent to eating cholesterol," medical experts believe that a single yolk contains less than 300 milligrams of cholesterol. For healthy adults, even eating one yolk a day is beneficial and harmless to health and will not lead to an increase in cholesterol levels.
Of course, for patients with hypertension, hyperlipidemia, hypercholesterolemia, and diabetes, it is advisable to eat fewer egg yolks, perhaps one yolk every 2-3 days. It is crucial to minimize the intake of other high-cholesterol foods such as animal内脏 and to engage in more exercise.
