Don’t make hard-boiled eggs “solid”. The protein will be denatured at 64OC, and an egg will solidify at 80OC. Therefore, it is best to boil eggs in a pot under cold water, boil the water for 3 minutes and then boil. At this time, the eggs are in a soft-boiled shape, and the nutrients are most beneficial to the body's absorption.

After washing the fresh and undamaged eggs, put them in the pot with cold water. After boiling, wait for 3 and 5 minutes respectively, take them out and let them cool down. "3-minute egg", the egg white is cooked and soft, and the yolk is just about to be cooked and slightly runny. "5-minute eggs", the egg white is cooked but tender, and the yolk is cooked but not hard.

According to nutritionists: eggs with different boiling times have different digestion times in the human body. "3-minute eggs" are lightly cooked eggs, which are easiest to digest and take about 1 hour and 30 minutes; "5-minute eggs" are half-boiled eggs, which take about 2 hours to be digested in the human body; eggs that are boiled for too long will not be digested in the human body It takes 3 hours and 15 minutes.

The "5-minute eggs" are not only soft and tender, but also beneficial to human nutrition. The American medical community published a research report that 24 adults ate two half-boiled eggs a day. After 6 weeks, the blood lipids did not increase, but the good cholesterol (HDL), which is beneficial to the human body, increased by 10%.
