Eating eggs every day can actually be bad for women's health
Introduction: In daily life, eggs are the most common nutritional food, often thought to have brain-boosting, liver-protecting, arteriosclerosis-preventing, cancer-preventing, and anti-aging effects. Women who eat one or more eggs per day have a higher mortality rate.
In daily life, eggs are the most common nutritional food, often thought to have brain-boosting, liver-protecting, arteriosclerosis-preventing, cancer-preventing, and anti-aging effects. However, a 14-year study conducted by Japanese scientists found that compared to their peers, women who eat one or more eggs per day have a higher mortality rate than women who eat only one or two eggs per week.
Eating more eggs increases the risk of heart disease
Japanese scholars selected 9,300 men and women as research subjects, all of whom had completed a lifestyle questionnaire in 1980, which included questions about the different foods they regularly consumed. The follow-up survey found that women who ate one egg per day had a 22% higher mortality rate than women who ate only one or two eggs per week (excluding factors such as age, smoking habits, and weight). Women who ate two or more eggs per day had an even higher mortality rate, although the number of such women was small. Women who ate the most eggs also had a higher probability of dying from heart disease and stroke, although the link between the two was not very strong from a statistical perspective. Scholars believe this may also be related to the fact that women rarely die from these two diseases. Nutrition experts believe that eggs should be boiled in boiling water for 5-7 minutes. Fried eggs that are too old will have scorched edges, and the high-molecular-weight proteins in the egg white will be converted into low-molecular-weight amino acids. These amino acids can often form toxic chemical substances at high temperatures.
Men can eat as many as they want: the reason is unclear
In men, there is no necessary link between eating eggs and mortality. The researchers are not clear about the reason for this phenomenon. They speculate that it may be because women have a clearer understanding of their own dietary habits.
Try not to eat egg yolks
Editor's tip
Under normal circumstances, healthy adults can eat 1-2 eggs per day; it is better for the elderly to eat one egg per day; it is more appropriate for mental workers to eat two eggs per day; pregnant women, postpartum women, lactating women, and those with weak bodies can eat 2-3 eggs per day, but no more. Boiled eggs are the best way to eat them, but they should not be overcooked.
Nutrition experts remind: try not to eat egg yolks
To this end, a reporter interviewed relevant nutrition experts. Experts pointed out that eggs are high-protein foods. If consumed in excess, they can lead to an increase in metabolic products and also increase the burden on the kidneys. Generally speaking, for healthy adults, as long as they pay close attention to and control the amount of cholesterol intake from other sources such as meat and dairy products, it is advisable to eat one egg per day, and try not to eat the yolk, because one yolk contains two-thirds of the daily cholesterol intake that a healthy adult should consume.
Boiled eggs should not be overcooked
Tips:
How to choose eggs—hold the egg in your hand, gently shake it to make the eggs hit each other, and listen carefully; or hold the egg and shake it to listen to the sound. High-quality fresh eggs will make a crisp sound when they hit each other, and there will be no sound when you shake the egg in your hand.
Boiled eggs: the most nutritious but should not be overcooked
In terms of cooking, for adults, boiled eggs are the best way to eat them, but they should not be overcooked. It is best to boil eggs in boiling water for 5-7 minutes, but you should chew slowly, otherwise it will affect absorption and digestion; however, for children, steamed egg custard and egg drop soup are the most suitable, because these two cooking methods can break down the protein, which is easily digested and absorbed by children. (In terms of nutritional absorption and digestion rate, boiled eggs are 100%, scrambled eggs are 97%, lightly fried are 98%, heavily fried are 81.1%, eggs cooked with boiling water or milk are 92.5%, and raw eggs are 30%-50%).
Fried eggs that are too old affect digestion
Fried eggs that are too old will have scorched edges, and the high-molecular-weight proteins in the egg white will be converted into low-molecular-weight amino acids. These amino acids can often form toxic chemical substances at high temperatures. In addition, it should be noted that tea-flavored eggs should be eaten less, because tea contains acidifying substances, which combine with the iron in eggs, irritate the stomach, and affect the digestive function of the gastrointestinal tract.
Reminder: Common mistakes when eating eggs
Mistake 1: The more eggs postpartum women eat, the better No, because the yolk contains rich lecithin, which is a powerful emulsifier that can make cholesterol and fat particles extremely fine, allowing them to pass through the blood vessel wall smoothly and be fully utilized by cells, thereby reducing cholesterol in the blood. Moreover, the lecithin in the yolk can release choline after digestion, which enters the blood and then synthesizes acetylcholine, the main substance of neurotransmitters, which can improve brain function and enhance memory. Mistake 3: Raw eggs are more nutritious Not only is eating raw eggs unhygienic and easy to cause bacterial infection, it is also not nutritious. Raw eggs contain avidin, which affects the absorption of biotin in food, leading to "biotin deficiency" symptoms such as loss of appetite, general weakness, and muscle pain. In addition, raw eggs contain "anti-trypsin," which will destroy the human body's digestive function. As for "maiden eggs," which have been incubated but have not yet hatched chicks, they are even more unhygienic.
