Eggs are one of the most commonly used ingredients in daily life.
An egg contains about 7 grams of protein, all eight essential amino acids needed by the human body, and is rich in lecithin. And the protein type and amino acid composition of eggs are perfect, second only to breast milk.
Eggs are inexpensive and made in a variety of ways, making them the best and cheapest food on the planet.
It is also because it is the most common and commonly used ingredients, about eggs also the most problems.
We sorted out four common questions and answered the questions of readers’ friends in a unified way.
Can I have raw eggs?
Old people are not advised to eat. even if you are young, eating raw eggs is risky.
1. Infection with acute gastrointestinal diseases.
Salmonella and other pathogenic bacteria can easily pass through egg shells and invade eggs; if the eggs are not fully cooked, the elderly, children or pregnant women with weak resistance may have acute gastroenteritis after eating eggs contaminated by pathogens.
2. Difficult to digest and absorb.
Raw eggs contain antitrypsin, which can inhibit the decomposition and absorption of protein by gastrointestinal digestive juice. at the same time, raw eggs are liquid and stay in gastrointestinal tract for a short time, so raw eggs are not easy to digest and absorb.
When the eggs are cooked, the nutrition is not destroyed. on the contrary, because of heating, the digestion and utilization rate of protein is improved.
3. Increase the burden on the liver.
Undigested protein, under the action of E. coli in the lower part of the large intestine, produces some toxic substances, some of which will be reabsorbed by the intestinal tract, through the blood circulation into the liver, increasing the burden on the liver.
4. Increase the infection rate of Toxoplasma gondii
The infection rate of Toxoplasma gondii in eggs has been unclear in academic circles. But it’s safer to eat cooked eggs than raw eggs.
The United States Department of Agriculture has issued reports reminding the public:
If the egg can maintain the fresh-keeping temperature below 7.2 ℃, the disease caused by it will be reduced by half; if the egg product is heated above 71 ℃, it can fully kill the pathogenic bacteria, and should be eaten as soon as possible after heating and ripening.
Eggs can’t be eaten with soy milk?
This statement is widely circulated.
The explanation given by those who believe in this view is:
There are trypsin inhibitors in soybean milk, which will inhibit the digestion of protein and affect the absorption of nutrition in eggs.
However, in fact, we all drink cooked soybean milk, trypsin inhibitor has long lost its activity in the process of cooking soybean milk, no longer has the effect of inhibiting protein digestion.
So rest assured, when drinking soy milk for breakfast, please match all kinds of eggs at will, do not worry at all.
However, if you like to pour raw eggs into hot soybean milk to drink, because the temperature of hot soybean milk is not enough to wash the eggs, it is necessary to consider the food hygiene and safety issues mentioned earlier.
How many eggs can you eat a day?
Most of the friends who ask this question are afraid of cholesterol in eggs and are afraid to eat too much.
It is widely believed that the more cholesterol you eat, the higher the cholesterol content in your blood and the higher your risk of coronary heart disease.
But many studies have found that “eating eggs leads to hypercholesterolemia” is untenable.
The level of blood cholesterol is not related to the total amount of cholesterol consumed every day, but more related to the amount of fat consumed and the intensity of activity.
So, for healthy adults, if you like to eat eggs, eating two or three eggs a day will not be a big problem.
Of course, because too much protein can increase the burden on the liver and kidneys. So if there is a problem with liver and kidney function, you should consult your doctor before eating.
What are the benefits of an egg a day?
Eating an egg a day may reduce the risk of heart disease or stroke, according to a study of nearly 500000 people in China.
Experts say egg intake needs to be combined with a healthy lifestyle to really make a difference.
The fear that eating too many eggs may be harmful to health seems to have proved untenable.
Professor (Prof Nita Forouhi) of Cambridge University said: “there are many limitations and shortcomings in nutrition research, but the most prominent conclusion of this study, which is based on a large-scale survey in China, is that. Eating an egg a day does not at least increase the risk of cardiovascular disease, and it may even be good for your health. ”
The study, published in the journal Heart (Heart), followed years of media coverage of poor eggs, such as the risk of salmonella and cholesterol.
As part of a healthy diet, many doctors now encourage patients to eat eggs, which are one of nature’s most nutritious foods. It is rich in protein, vitamins A, D, B and B12, as well as lutein and zeaxanthin, which are good for the elderly.
