Many people who lose weight and keep fit often only eat egg whites and discard egg yolks because they think egg yolks are high in calories and cholesterol, but experts believe that eating eggs should not exclude egg yolks. There are several reasons:

Egg yolk contains antioxidants, vitamin B 12, vitamin A, iron, selenium, biotin, phosphorus, choline and various other micronutrients. Choline, which is particularly lacking in Americans, is an important nutrient to promote brain function, nervous system and body detoxification.

2. The body needs cholesterol, which has many important functions, such as building and repairing cells. Studies have shown that there is almost no connection between dietary cholesterol and high cholesterol levels in the blood. The liver itself produces cholesterol, so if there is more cholesterol in the diet, the liver will produce less cholesterol.

3. Eggs are an important source of protein, which are rich in all essential amino acids, and each egg contains about 6 grams. Vegetarians and meat eaters can get protein from eggs.

4, eating a comprehensive food helps digestion, eating some parts of food, such as eating only egg whites, will make the body feel that it has not finished eating the whole food. In other words, the body will have a desire for other parts of the food, so it is best to eat the food completely.
