How to choose healthy food? Scientist: don’t be fooled by its magical effect. Choose food reasonably

Food is essential to human beings every day, and the energy source of human body is food. But we also know that disease comes from the mouth, and the source of disease is also food. 90% of the diseases come from eating. Therefore, modern people pay attention to nutrition, reasonable diet, eat healthy.

Eating is a great knowledge. If you eat well, you will live a long life. If you don’t eat well, you will be sick. In order to pursue health, there are a lot of strange sayings in modern society: today, mung bean is used to cure all kinds of diseases, tomorrow, eggplant is used to absorb oil, and the day after tomorrow, okra is used to heaven. Today, I’d like to talk about food and nutrition.

The human body can’t do without energy, and these nutritional energy can’t be synthesized by the human body itself, so it needs to be taken from the outside world. The human body needs more than 40 kinds of nutrients, which can only be obtained through eating, drinking or some other nutritional effects. Under normal circumstances, we all get them through food. But if the nutrition is not properly obtained, a certain kind of nutrition exceeds the standard or does not reach the standard, the body will appear a kind of morbid state, which is what we usually call sub-health state. Therefore, the nutritional content of some common foods should be considered.

The type of nutrients refers to the amount of nutrients contained in a food. Some foods contain more comprehensive nutrients, such as eggs, milk; some foods are single, such as edible oil.

Some foods contain more single or certain nutrients, such as vitamin C in fresh vegetables; some foods contain less or no nutrients, such as vitamin C in eggs. Comparing the content of vitamin C alone, vegetables are more nutritious than eggs. If you compare protein, eggs are more nutritious than vegetables.

In addition to considering the type and content of nutrients in food, we also consider its absorption and utilization efficiency. Different foods contain the same or several nutrients, but due to different absorption and utilization in the body, the contribution to nutrient intake is also different. For example, milk is rich in calcium and other minerals, which are easily absorbed and utilized by the human body; vegetables also contain a lot of calcium and other minerals, but due to the influence of phytic acid and other factors, these nutrients can not be well absorbed and utilized by the human body. Compared with cereals, iron content in meat is not only rich, but also easy to be absorbed and utilized.

In addition to the food itself, the different physiological conditions of the human body will also affect the absorption and utilization of nutrients. For example, the absorption and utilization rate of calcium and other nutrients by growing and developing children, pregnant and lactating women is higher than that of other people.

In the past, when people had a bad life and had no enough to eat, they used to eat coarse grains, such as corn and white flour. Ordinary people couldn’t afford them, but they were very healthy and healthy. In modern times, there is no shortage of such fine grains as Baiguan, which everyone can afford. On the contrary, there are fewer people who eat coarse grains like corn, and their health problems are also constant. This is due to the imbalance of food nutrition.

Today’s food is too refined. It’s easy to suffer from vitamin B deficiency if you always eat this kind of food. Modern people lack a lot of vitamins. In fact, the reason is very simple, that is, you eat fine grain every day. Often eat some coarse grains can play a supplementary role. In addition, often eat some potatoes, such as sweet potatoes, potatoes, these foods are rich in dietary fiber, can prevent constipation, prevent cancer. But today’s coarse grains are not cheap, they are much more expensive than these fine grains.

Many people have said that eating a meal is so complicated. We should not only consider the nutrition, but also the content of food. In fact, eating out nutrition is not complicated at all, and it doesn’t cost much. It’s mainly to pay attention to the collocation at ordinary times.

First of all, breakfast must be eaten. Nowadays, people are busy with work, and many young people like to sleep in. They get up late in the morning, and it’s almost time to go to work, so they don’t eat breakfast. In fact, breakfast is very important in three meals a day. Many diseases are caused by not having breakfast. In fact, it’s very easy to have breakfast. If you have time, you can make it richer and eat better. If it’s too late, there’s always time to get up in the morning to make a cup of milk and eat an egg. The total time is no more than 10 minutes. Xiaobian does this. In the evening, he cooks some eggs and puts them in the refrigerator. The next day, he gets up to make a cup of milk and eat an egg. The total time is up to 10 minutes.

Don’t worry about eating breakfast, as long as you eat. Lunch and dinner can be matched according to your own situation. The overall nutrition match is not to eat single food. You can match vegetables, fine grains and coarse grains, and eat meat once a week. In this way, you can eat healthy food, and spend less money. On the contrary, you just eat a few kinds of food every day. Not only can you not eat healthy food, but also you waste money.

Do you guys understand? Reasonable collocation of food, eat healthy, only a healthy body can have a better future.
