Is it not good to cook steamed vegetables at home for a long time? The longer vegetables are steamed, the greater the harm to human health. When cooking green leafy vegetables, many people choose to cook for a long time, which is unhealthy. Green leafy vegetables should not be boiled for a long time when cooking, otherwise the nitrate in green leafy vegetables will be converted into nitrite, which is easy to cause food poisoning and harm to the body. Although cooked food is more nutritious, it is for meat, first of all, meat. Vegetables and most vitamins are quickly destroyed at the high temperature of steam, so they are not suitable for cooking. It's best to eat as a meal.

I often learn to cook at home. As for how long it takes to steam, I think it can steam vegetables for about 20 to 30 minutes. If the steaming time is too short, the steamed food will be a little hard and not very delicious. If the steaming time is too long, all the nutrients in the steamed dishes will be lost, which is not delicious.

Is it not good to cook steamed vegetables at home for a long time? Generally speaking, the influence of cooking methods on the nutritional value of food depends on the type of raw materials, temperature, time and specific nutritional components. It is generally believed that steaming, boiling, stewing and scalding are the best cooking methods, which can protect the nutrients in food to the greatest extent. Of course, trying not to mean no loss, but certainly not without nutrition.

The reasonable collocation of nutrients in daily life can ensure the adequate supply of nutrients, not that a certain food will affect the normal absorption of nutrients, but also the addition of various nutrients. You can do this in your daily life. There is no need to care too much about these things, so as not to cause psychological pressure. Because I like steamed food, it is very convenient. In the future, I will only eat steamed vegetables, not stir-fry, and there is no problem with the combination of meat and vegetables. It is entirely possible to eat like this for a long time. But it can't be steamed for too long, otherwise it may destroy nutrition. Steamed vegetables are better than stir-fried vegetables. After all, the temperature is lower and the nutrition is not easy to destroy, but it is better to cook and eat some cold dishes.
