Boiled eggs cooled in cold water are unhealthy; don't eat more than 3 egg yolks per week.

Protein is one of the six essential elements for life, and eating eggs is an excellent way to supplement protein. Do you know the benefits of eating eggs for breakfast? The Water Health Channel recommends boiled eggs, as this best preserves their nutrients. However, the Water Health Channel reminds you that while soaking boiled eggs in cold water can cool them down, this method is not scientifically sound; it's best not to soak boiled eggs in cold water. So, how should boiled eggs be cooled? The Water Health Channel has summarized boiling and cooling techniques for boiled eggs; let's take a look.

I. Seven benefits of eating eggs for breakfast

2. Eggs keep you feeling full longer than cereal or noodles: The protein and fat in eggs help maintain your energy levels, keeping you feeling full and preventing you from having a morning snack.

3. Eggs will not affect your cholesterol levels: While eggs do contain some cholesterol, the claim that eating eggs can affect your blood cholesterol levels has been proven false. Therefore, there is no need to worry that eating eggs will increase your risk of heart disease.

4. Eggs help brain development and improve memory: Choline-one of the basic components of eggs-stimulates brain development and function. This is related to prolonging memory retention, enhancing recall, and increasing alertness.

5. Eggs protect your eyes: Two antioxidants in eggs, lutein and zeaxanthin, are associated with protecting the eyes from UV damage. This is also linked to reducing the incidence of age-related cataracts.

6. Eggs help you lose weight: As mentioned earlier, eggs are more filling, which naturally helps with weight loss. Studies have shown that people who eat eggs for breakfast are more likely to lose weight than those who eat bagels.

7. Eggs are relatively inexpensive: Compared to other high-protein foods, such as "red meat," even free-range eggs, which are slightly more expensive, are still relatively cheap.

For office workers, every second counts in the morning, and boiled eggs are the simplest and quickest way to preserve their nutrients.

II. Water-Healthy Living Tips – Techniques for Boiling Eggs

Don't boil eggs in boiling water. First, boiling water will cause the eggs to roll around in the pot, easily cracking the shells and even exposing the egg white. Second, the coagulation and denaturation of egg proteins doesn't require very high temperatures, usually 60℃-87℃ is sufficient, while boiling water reaches 100℃. If you boil eggs in boiling water, the egg white may become as tough as rubber. Therefore, when boiling eggs, the lid should be off, allowing the water to bubble gently, rather than boil vigorously.

Cook for a short time and cool after cooking. Eggs that are fully cooked and have a completely set yolk need to be cooked for 10 minutes, but if you want a soft-boiled egg with a runny yolk, about 6 minutes is enough. Overcooking eggs will result in an unpleasant sulfurous smell. Also, be sure to cool the eggs immediately with cold water after removing them from the pot; otherwise, the residual heat will continue to cook the eggs and make them overcooked.

Slightly older eggs are easier to peel. We all think the freshest is best, but for hard-boiled eggs, it's not necessary to use very fresh ones. Slightly older eggs are actually easier to peel. If you store eggs in the refrigerator for a few days, their pH level will rise slightly, and the adhesion between the egg white and the inner shell will loosen slightly.

It's okay if the yolk turns green. If an egg is overcooked, you'll notice a green layer on the yolk. This is due to a reaction between sulfides and iron in the yolk, and it's harmless. Just don't overcook it to avoid this.

However, many people choose to soak eggs in cold water when cooling them before boiling. This is actually wrong! Why can't you soak eggs in cold water to cool them? How should you cool them instead?

III. Water Health Channel Reminder – It's best not to soak boiled eggs in cold water.

Immersing hard-boiled eggs in cold water does indeed cool them down quickly. The inner shell membrane and the egg white membrane contract at different rates when cooled, creating gaps that make the shell easier to peel. However, this ignores the fact that cold water contains a large number of bacteria. When an egg is heated, the shell membrane that prevents bacteria from passing through is damaged. This means the pores in the shell no longer block bacteria, allowing them to easily invade the egg.

The correct method is to add a small amount of salt during the boiling process of the eggs. Salt can kill bacteria and detoxify, and it can also create a certain gap between the eggshell membrane and the egg white membrane due to the different degrees of contraction, making the eggshell easier to peel off.

It seems we need to change the old methods we've been using. To ensure our eggs are free from bacterial contamination, we should stop soaking them in cold water.

IV. Water Health Channel Reminder: Do not eat more than 3 egg yolks per week.

Healthy eating guidelines recommend eating no more than three egg yolks per week, with no limit on egg whites, and a daily intake of no more than 300 milligrams of cholesterol. Egg whites contain neither fat nor cholesterol, making them nearly pure protein, so their intake is not as restricted as that of egg yolks.

Because all the fat and cholesterol are in the yolk, you should minimize the use of yolks when cooking. For example, you can use four egg whites and three egg yolks for steamed eggs, or two egg whites instead of one egg for a cake. These methods can reduce the fat and cholesterol in your diet. Have you noticed that frying eggs requires a lot of oil? It turns out that a boiled egg contains 72 calories, but a fried egg contains 120 calories!

Eggs are rich in complete protein and are considered a meat or meat substitute in the food pyramid because their nutritional composition is similar to that of meat. No one will lack certain nutrients by not eating eggs; however, eating raw eggs may lead to Salmonella infection, which can cause severe symptoms such as abdominal pain, vomiting, and diarrhea. Eating raw eggs can also hinder the absorption of a nutrient called biotin.

Egg yolks are often touted as a brain-boosting food because they contain lecithin. However, the body can produce lecithin itself, and unless there's a problem with this function, there's no need to obtain extra lecithin from the diet. Furthermore, soybeans and their products also contain lecithin, so this is even less of a reason to eat eggs. Therefore, no one, including fitness enthusiasts, pregnant women, and children, should eat eggs every day.

Eggs are good, but don't eat too many!
