Eggs are recognized as healthy food, but some people say that they cannot eat eggs due to their high blood lipids. Some people say that overcooked eggs can cause cancer in the body. Is this true?

Will overcooked eggs cause cancer?

There is a saying that boiled eggs for a long time will have a layer of dark green yolk, which will cause cancer! In fact, the egg will turn green after being boiled for a long time, but it is a chemical reaction. It will not threaten people's health, and it will not affect the nutritional value of the egg itself.

So why do the yolks turn green? The reason why the egg yolk turns green is because it contains many elements that are easily oxidized and react, so the egg yolk will turn green after cooking for too long.

The longer it cooks, the darker the color will become as the temperature rises, from gray-green to greener and even black.

Of course, there are certain ways to prevent the yolk from turning green, that is, when cooking the eggs, master the proper heat, so that the yolk will not turn green again.

If you eat eggs every day, you don't necessarily know how long the eggs will take to cook, not too long or too short.

How long does it take to boil an egg

Eggs cooked at different times are in different states, and you can see how long it takes to cook by looking at the comparison.

One minute: The taste of eggs boiled for one minute is basically the same as eating raw eggs, but the egg white is slightly solidified, and the bacteria in it still exist, which will affect the body, so everyone should eat it carefully.

Three minutes: Cook until three minutes before the egg whites start to solidify, and the egg yolk begins to change color, but the taste is still not much different from that of raw eggs, so you should still eat them carefully.

Five minutes: The egg whites cooked for five minutes are very tender, and the egg yolks are starting to set.

Seven minutes: At this time, the egg white is particularly tender, and the egg yolk is not completely solidified. Take a bite and the egg yolk will flow out.

Nine minutes: After cooking for nine minutes, the egg whites also become normal, but the yolks are still in the state of candy. Friends who want to eat soft eggs can try cooking for nine minutes.

Eleven minutes: At this time, the egg whites and egg yolks are very normal, and the taste is very good.

Thirteen minutes: Cook for 13 minutes until the egg whites are firm, the texture is Q-like, and the egg yolks are dry and light yellow in color.

Fifteen minutes: After 15 minutes of cooking, the egg white becomes inelastic, the egg yolk becomes drier, and some black films may appear. The ferrous sulfide contained in this black film will affect the absorption of iron.

Usually boiled eggs are boiled in cold water, and the eggs should be washed before cooking. It is best to cook for 5 to 8 minutes. At this time, the egg yolk liquid begins to solidify, and the egg white is also very tender, which is the time when the taste is the best.

Skills for cooking eggs

1. Clean the eggs before cooking, otherwise the pores on the surface of the egg shell will easily absorb a lot of dust, bacteria and germs. If you heat it without cleaning it first, it will easily cause the pores to open, allowing these bacteria and germs to penetrate into the eggs, which will affect your health.

2. When many people cook eggs, there is often a pot of frangipani. This is because the boiling water is put into the pot to cook, so it must be boiled in cold water.

3. The cooking time should be short, and it should be cooled after cooking. Eggs with fully cooked whites and fully coagulated yolks need to be cooked for 10 minutes, but if you want a hard-boiled egg with a tender yolk, about 6 minutes will do.
