Eggs are nutritious, rich in protein, vitamins and various minerals. A small egg can basically meet most of the nutritional needs of an adult in a day.
Put the eggs in a pot with cold water, and start counting when the water boils.
1~3 minutes: the protein is not fully cooked, and the yolk is all raw. This familiarity is not recommended for everyone.
5 minutes: the protein is soft, and the yolk is still liquid.
6~7 minutes: protein is fully mature, and the edge of yolk begins to harden, which is a delicious egg.
10 minute: The yolk is fully cooked.
When cooking eggs, put them in cold water first, then add 1-2 spoonfuls of vinegar, and put them in cold water immediately after cooking, so that the eggshells can be easily peeled off.
Different methods of boiled eggs, poached eggs and scrambled eggs have great influence on their nutrient absorption. The boiled egg with shell, which we are most familiar with, can best absorb protein and supplement nutrition. Without adding a drop of oil, the cooking temperature is not high, and the cholesterol in the egg yolk is not exposed to oxygen. Some research data show that the protein digestibility of boiled eggs is as high as 99.7%, which can be almost completely absorbed and utilized by the human body.
Eggs and sweet potatoes can be eaten together, except for people with poor gastrointestinal function. Eggs contain a lot of protein, and sweet potatoes contain a lot of starch. Eating the two together will not have any reaction, but will promote absorption because of balanced nutrition. However, for people with poor gastrointestinal function, eating more sweet potatoes is prone to abdominal pain, bloating and other discomfort, and eating more foods containing high protein such as eggs may aggravate discomfort.
