The protein and fat content of boiled salted duck eggs are 1.14 times and 1.3 times that of boiled eggs respectively, and the calories are 1.2 times higher than those of boiled eggs. The potassium content is also good, 226mg/100g, which is 1.7 times that of boiled eggs; selenium The content is quite outstanding, 32.8 micrograms/100 grams.[1]
Although the above nutrients of boiled salted duck eggs are richer than those of boiled eggs, they are pickled products after all. The sodium content is as high as 1131mg/100g, which is nearly 9 times that of boiled eggs. The sodium content of raw salted duck eggs is higher, 2706mg/100g. Diet A little carelessness can easily lead to excessive salt intake throughout the day, which is detrimental to health.
What will happen to your body if you eat 1 salted duck egg a day?
Although the salted duck eggs go well with rice and are really delicious. However, 1 salted duck egg a day could be a real problem.
The “Dietary Guidelines for Chinese Residents” recommends that each person’s daily salt intake should be controlled below 5 grams, which is equivalent to less than 1 beer bottle cap.
One salted duck egg can give us 2 to 5 grams of salt, and we have to eat other dishes. The salt intake throughout the day can easily exceed the standard.
1. Not conducive to blood pressure control:Many studies have proven that a high-salt diet will increase the risk of high blood pressure, accelerate vascular aging, and increase the risk of stroke.
2. Induce gastritis:Excessive salt intake will irritate the gastric mucosa and may cause the gastric parietal cells to fall off[3]and parietal cells are the barrier that protects the health of the stomach. Once destroyed, it will increase the risk of gastritis and may even induce gastric cancer.
3. Increase the risk of osteoporosis:Excessive sodium intake in the diet will inhibit the differentiation and function of osteoblasts. Animal experiments have shown that a high-sodium diet will reduce bone density and bone strength in rats and increase the risk of fractures.[4]
In addition, eating too salty will cause people to drink a lot of water. Drinking a lot of water will increase urination. When urinating, not only sodium ions will be excreted, but also some calcium ions will be excreted. Therefore, the saltier you eat, the more likely you are to suffer from calcium deficiency and osteoporosis. 4. Impair cognitive function: Studies have shown that a high-salt diet may impair certain cognitive functions, especially for the elderly.[5]
In addition, studies have shown that reducing my country’s high salt intake may significantly reduce the prevalence of cardiovascular disease. Eating 1 gram less salt per day can reduce the risk of ischemic heart disease by about 4% and the risk of stroke by about 6%. By 2030, reducing salt intake by just 1 gram per day can prevent nearly 9 million cases of heart disease and stroke. cases and save 4 million lives.[6]
Therefore, although salted duck eggs are delicious, it is okay to eat them occasionally. But if you particularly like salted duck eggs, you should pay attention to controlling your salt intake throughout the day!
Salted duck eggs are “so rich and oily”. Has the fat increased?
The most attractive thing about salted duck eggs is the sandy and oily yolk, while boiled duck eggs will not be oily. Some people may wonder: Does the fat content of duck eggs increase after they become salted duck eggs? In fact, there is not much change in fat content, but the state has changed.
The reason why you can’t see the clear oil in the boiled eggs you usually eat is because the protein and fat in the egg yolk form an emulsification system, and there is no oil on the outside.
The pickling process will cause the hydrophobic groups to separate from the hydrophilic and lipophilic groups in the yolk, destroying this emulsification system.[7]The small oil droplets gather together and become “rich and flowing oil” visible to the naked eye.
How to distinguish between real and fake salted egg yolk?
Many delicacies we eat in life are inseparable from the participation of salted egg yolk, such as egg yolk cakes, egg yolk lotus paste mooncakes, salted egg yolk fried rice, salted egg yolk baked shrimps, quicksand buns, etc. In order to more conveniently meet the production needs of these delicacies, many people will buy salted egg yolks directly.
However, the salted egg yolks on the market may not be real salted egg yolks. Most of them are artificial salted egg yolks. How to identify them?
1. Look at the packaging and ingredient list:Artificial salted egg yolk packaging is usually labeled “salted egg yolk products”, and most of the ingredient lists contain starch, natural carotene, food flavors, etc.
Although there is also an egg yolk, it is not necessarily a duck egg yolk, it may also be an egg yolk.

2. Look at the status:The structure of real salted egg yolk is uneven, soft on the outside and tight on the inside, with a hard texture; while artificial salted egg yolk has a uniform and elastic structure, and there will be no layering or hard core after biting into it.
Since artificial salted egg yolk contains starch, it will become thicker after being boiled. Real salted egg yolk has good fluidity and is not sticky after being boiled.
3. Look at the price:The price of real salted egg yolks is generally 1~1.5 yuan/piece, while artificial salted egg yolks are cheaper, mostly 0.3~0.5 yuan/piece. You can buy 100 “salted egg yolks” for 30 yuan.
