How many eggs to eat each day?
Experts said that people still have a big misunderstanding about eating eggs, that is, eating eggs and whites do not eat egg yolks. “I once had a breakfast buffet at the hotel and found that there were a lot of egg yolks scattered on the table. I felt very sorry. The clear nutrition of eggs is not as good as the yolk. It is simply wasting in the name of nutrition! Some people think that the protein content of egg white is high. In fact, according to the modern dietary pattern, it is easy to obtain enough food with about two grains per day, a bag of milk, an egg, some soy products, two or two kinds of meat, plus about one kilogram of vegetables and fruits. Protein does not require extra egg whites at all.†“All kinds of notoriety that people put on their eggs are actually looking for scapegoats for their own improper lifestyles. Too much red meat eats too much oil. Health hazards are far more serious than eating one or two eggs or egg yolks,†said the expert.
In response to the nutritional needs of different populations, the consumption of eggs does vary. Experts recommend that children, pregnant women, nursing mothers, and people with large amounts of exercise have higher protein requirements than ordinary people and can eat 1-2 eggs a day. Some people also eat less meat in the diet and can also eat according to this standard. Normal adults and seniors eat 1 egg a day. For patients with dyslipidemia or obesity, it is advisable to eat 2-4 eggs per week. "It's best to eat in the morning or at noon, to provide adequate nutrition for the day's work, and to avoid excessive cholesterol intake at night." Experts cautioned that the number of eggs eaten is not static. “Some people are accustomed to having a boiled egg every morning, but if you know that you might be eating out the same day, you can omit the egg because the protein in the restaurant will exceed the standard.â€
For the way of cooking eggs, experts believe that frying and frying can be done. "Cup of steamed egg and egg soup is the easiest to digest, suitable for children, the elderly and the patient. The lack of vitamin C is the only 'short spot' of eggs, so with tomatoes, green peppers, and hot peppers, you can make up for deficiencies. Poached eggs are also good. If you feel that the taste is monotonous, you can cut the boiled egg and mix it into salads or cold dishes. In contrast, fried eggs have higher calories and should not be eaten.â€
