How many eggs is the best to eat a day?
First of all, we need to know the nutrition of eggs. An egg of about 50 grams contains about 7 grams of protein, 6 grams of fat and 82 kilocalories. The proportion of amino acids in eggs meets human physiological needs and is easy to absorb. Rich in lecithin, it can enhance memory. In addition, eggs also contain vitamin A, vitamin E, phosphorus, zinc, iron and other substances. So, an egg is one? Ideal nutrition pool? These nutrients are easily absorbed.
Secondly, the cholesterol level in blood is related to factors such as fat content and activity level, but has nothing to do with the daily intake of cholesterol. 50 grams of eggs contain 188 mg of cholesterol, mainly concentrated in the yolk. In order to meet the nutritional needs of different people without malnutrition, the amount of eggs eaten by different people will be different. For example, the elderly can eat 1-2 eggs a day, young and middle-aged people engaged in mental or physical labor can eat 2-3 chickens a day, while pregnant women, pregnant women, nursing mothers and even patients can eat 2-3 chickens a day. In addition, obese and three high patients are sensitive to cholesterol, so it is best to consult a doctor before eating.
Finally, eating two eggs a day is not a problem, but people with high cholesterol should pay attention to their diet. In addition, egg yolk is nutritious and should not be discarded.
How many minutes does it take to boil eggs?
Protein is the most precious egg, but if it is cooked for a long time, protein will be denatured and its nutrition will be greatly reduced. Therefore, everyone should pay attention to the cooking methods of eggs to maximize their nutritional value.
(1) Before boiling the eggs, put the eggs in cold water, which can reduce the pressure on the eggs, and then start counting after the water boils.
② Eggs with different maturity will be cooked at different times. Cook the egg whites and egg yolks for three minutes. At this time, the nutrition of the egg is preserved to the maximum extent, but salmonella is not completely killed, and it takes 90 minutes for the human body to digest it completely.
③ After cooking for 5 minutes, the yolk is slightly solidified, the color is golden yellow, and the anti-nutritional ingredients are destroyed. Salmonella is the most nutritious egg within a safe range.
④ When boiling for more than 10 minute, the protein structure will be denser and more difficult to digest. Sulfide decomposed by methionine will react with egg yolk to produce iron sulfide, which is difficult to absorb and loses nutrition.
In other words, it is best to cook the eggs for another 5 minutes after they are boiled. They taste soft and waxy, and they are safe. They can keep the nutrition of eggs well.
Eggs are nutritious, but you can't eat too much. You should calculate the quantity according to your personal needs. In addition, you should also master the heat of boiled eggs. Eggs boiled for 5 minutes after boiling water are perfect.
