Today, we are going to talk about eggs, which are loved by almost everyone in daily life. Eggs are not only delicious, but also rich in various nutrients. They are a common guest on many family tables. But do you really understand the various sayings about eggs? Today, we will reveal eight truths about eggs →

1. Is it really healthy to eat one egg a day?

First, let's answer this most common question. In 2018, a study published in the journal Heart by Professor Li Liming's team from the School of Public Health of Peking University showed that by following up nearly 500,000 people for an average of 8.9 years, it was found that eating one egg a day helps reduce the risk of cardiovascular disease and death. Therefore, eating one egg a day will not only not increase the burden, but will help health.

2. Eggs are high in cholesterol. How much can I eat?

Many people are worried about the high cholesterol content in eggs and strictly control their daily intake. In fact, 80%-90% of the cholesterol in human blood is synthesized by the human liver, and only 10%-20% comes from food. Although eggs are high in cholesterol, they are low in saturated fat, so they have almost no adverse effects on the cholesterol level in the blood. For healthy people, it is safe to eat 1-2 eggs a day.

3. Only eat egg white and not the yolk?

Eating only egg whites without eating the yolk is like drinking yogurt and only licking the milk cap, which misses a lot of nutrients. In fact, in addition to protein, the yolk also contains essential fatty acids, lecithin, vitamins, calcium, zinc, choline, betaine, lutein and other nutrients. Therefore, the yolk is the essence of the egg , and you must not give it up easily.

4. Are half-boiled eggs more nutritious?

Some people like to eat half-cooked "soft-boiled eggs", but did you know that half-cooked eggs are not only less nutritious than fully cooked eggs, but they are also prone to food poisoning. The protein structure of raw eggs is tight and difficult to digest and absorb; while the protein structure of cooked eggs becomes loose and easier to be absorbed by the human body. In addition, raw eggs are prone to carry salmonella, which can cause serious food poisoning.

5. How long is the best time to boil eggs?

It usually takes 7-10 minutes to boil eggs . If you cook them for too long, it may cause oxidation of fatty acids and cholesterol, but the overall impact is not significant.

6. Does the color of eggs matter?

The color of the eggshell is mainly determined by a pigment called protoporphyrin, but this does not affect the nutritional value of the egg inside. Eggs of different colors have little difference in nutrition.

7. Which is better, free-range eggs or caged eggs?

In the market, free-range eggs are often more expensive, but are they really more nutritious? Scientific research tells us that the nutritional content of eggs is similar whether they are free-range or caged. So, next time you buy eggs, don't worry too much about the "living environment" of the chickens.

8. Can I eat eggs on an empty stomach?

Will the protein be wasted if you eat eggs on an empty stomach? The answer is: No! The human body will give priority to other energy sources and will not let the protein be converted into calories in vain. So, when you get up in the morning, feel free to eat your eggs!

Finally, let’s summarize:

Eat one egg a day and you’ll stay healthy. The nutritional value of egg yolks should not be underestimated. They come in a variety of colors, and fresh is best.
