Why is it bad to eat nutritious food alone, and how can nutritious food not be nutritious?

Hehe, to put it simply, no nutritious food can fundamentally replace natural food, and the nutrition of natural food is not explained by a few simple nutrients.

Dietitians in Europe and the United States say that they will not let you eat health products as a last resort, and doctors in Europe and the United States will also not prescribe antibiotics as a last resort.

What about China? Take health products at every turn, and take antibiotics for minor illnesses.

What the human body needs is best taken from high-quality foods.

The "nutritious food" provided on the market today is exaggerated and focuses on certain functions and has little to do with the actual benefits, so people in the industry say: supplements are general products, nutrition is to promote ......As long as you ensure that three meals a day are matched with meat and vegetables, the nutrition is enough. You don't have to pay for sin.

Don't blindly eat nutritious food, how can it be unnutritious?

Preparing our three meals a day exactly as required by a nutritious recipe, but it doesn't seem to help our health much, is it because there is a problem with the recipe given by the experts, or is the nutrition stolen? Well-cooked food is good for human health, but many nutrients will be destroyed if food is not cooked properly during processing.

1. Staple food: insoluble vitamins and inorganic salts in rice and noodles are easily lost. For example, when making rice washing, the loss of nutrients increases with the increase of the number of rice washing and soaking time.

Boiling porridge and steamed steamed buns: adding alkali can destroy vitamin B1 and vitamin C.

Fried fritters: Vitamin B2 and vitamin C are lost by about 50% due to alkali and high-temperature frying, and vitamin B1 is almost lost.

Making noodles: Lo mein loses more nutrients than eating noodle soup.

Therefore, in order to protect nutrients and reduce losses, it is better to steam and brand rice and noodles when making rice, and it is not suitable to boil, fish and fry.

2. Non-staple food: cold dressing: cut the tender cucumber into thin slices and put it for 2 hours, and the vitamin loss is 33%-35%; Left for 3 hours, the loss is 41%-49%.

Steaming: Heating with water vapor can not only maintain the shape of the food, but also not destroy the flavor of the food, but it will destroy part of the vitamin B.

Stir-fry: Stir-fry quickly with high temperature, in addition to the loss of vitamin C, the loss of other nutrients is not large. If you add too much water, a large amount of vitamins will be dissolved in the water, and if you don't eat vegetable soup, the vitamins will be lost.

In particular, if the vegetables are boiled first, and then the juice is squeezed out and then fried, the loss of vitamins and inorganic salts is even more serious. When stir-frying, salt should not be added too early, and starch should be used to thicken, because starch has a good protective effect on vitamin C.

Frying: Frying is the use of a small amount of oil to fry food quickly, such as fried eggs, fried shrimp cakes, etc., because of its short time, the loss of nutrients is not large. Frying is to put food in a large amount of high-temperature oil to heat, for a long time, so all nutrients suffer a significant loss, protein will also deteriorate and reduce the nutritional value, fat will also be destroyed and lose its function, and even produce substances that hinder the absorption of vitamin A.

To preserve protein and vitamins, frying batter is often the best remedy.

Cooking: When vegetables are heated with water, the water-soluble vitamins and inorganic salts in the vegetables will be dissolved in water, so that carbohydrates and proteins will be partially hydrolyzed. Therefore, it is best to eat vegetables with soup, or use fresh soup as a condiment for some dishes.

When boiling vegetable soup, the water should be boiled, and the time should be short.

Smoked: Vitamins A, B, and C can be greatly damaged. After meat and fish are smoked and roasted, the incomplete combustion of fat and the incomplete decomposition of starch after heating can produce carcinogens.

Soup occupies an important place in the diet of Chinese. Many people believe that "eating meat is better than drinking soup" and think that the nutrients are all in the soup. However, in recent years, there is a view that whether it is chicken soup, meat soup or fish soup, the nutrients contained in the soup are very few, far less than the ...... of the ingredients themselvesWho is more nutritious?

What's in the soup?

From a modern scientific point of view, the nutrients that meat provides us with are mainly minerals such as protein, fat, vitamins, and calcium. The amino acid composition of meat protein is relatively close to the needs of the human body, and the digestibility is high, which is the best high-quality protein. Minerals such as iron and zinc are easily deficient in many people, and meat is more abundant and easier to absorb.

Fat is a high-calorie nutrient, and it can also be regarded as a "very nutritious" ingredient when there was a shortage of food and clothing in ancient times. However, for most modern people, the calorie intake is already too much. Excess fat not only contributes a lot of calories, but also increases the risk of cardiovascular disease.

In the process of making soup, fats and water-soluble vitamins are more likely to escape from the meat into the soup. The fat-soluble flavor substances are dissolved in the fat and enter the soup with it. During long-term high-temperature stewing, some proteins in meat and bones are hydrolyzed, releasing some amino acids, which and some of the free amino acids in the ingredients themselves enter the soup.

Some amino acids produce umami, such as glutamic acid, which is the chemical component of MSG. Bones and some other ingredients used in soups contain umami substances, such as mushrooms, which are rich in inosinate and guanylate. During the stewing process, they also run into the soup and become sodium inosinate and sodium guanylate, two substances known as "flavored nucleotides".

In addition, during prolonged heating, some free amino acids react with the sugars in the soup to form flavor substances. Together, these different flavor substances bring a rich umami flavor to the soup. The longer the simmer, the more these ingredients enter the soup, and the more delicious the soup will be.

However, the amount of these flavor substances has nothing to do with nutrition. Although amino acids such as glutamic acid are also nutrients, they are not in large amounts, so their contribution to nutrition is not worth mentioning.

More than 90% of the malnutrition seen in clinical nutrition is mainly caused by disease. Therefore, malnutrition should first lead to the primary disease, because many diseases can easily affect people's appetite and lead to a decrease in nutrient intake; In addition, due to the knowledge of one's own disease, it leads to depression, decreased appetite, reduced nutrient intake, and gradually appears to be emaciated in the long run, resulting in malnutrition.

Poor eating is not necessarily malnourished, indigestion will definitely be malnourished, and no matter how good you eat, you can't absorb it.

The results that malnutrition will cause: 1. It will cause a decline in mood, and the mood will become more depressed, because malnutrition Heng Chongling will cause disorders of metabolism in the nervous system, which will then manifest itself emotionally, and it is easy to be depressed and depressed. 2. It is easy to cause a high incidence of fatigue, because malnutrition will cause a lack of energy and nutrients in the body, which will cause a very obvious sense of fatigue.

3. It will cause low immunity, because malnutrition will affect the reduction of raw materials for the production of immune substances, and then it will cause a decrease in resistance due to the decrease of immune substances, and it is easy to suffer from infectious diseases.

Eating too little can lead to nutritional deficiencies.

If you eat too little, it is recommended to diversify the food as much as possible, eat three meals at the same time, it is best to be full for seven or eight minutes, and you can eat a fruit between meals, so that the diet is easy to digest, does not increase the burden on the stomach, and can also ensure the intake of nutrients.

If you don't eat well, it will lead to unbalanced nutrition in the body and lead to malnutrition! For example, if you don't eat three meals a day on time, or the food you eat is relatively simple, or even picky eaters, and other conditions that affect your diet, you can't eat well, then it will affect the body's nutritional imbalance and make it easy to get sick!

So, how to eat three meals a day to be more nutritionally balanced?

First, breakfast must be eaten. Because you have just woken up from sleep in the morning, the choice of breakfast food should be easy to digest and nutritious. Breakfast should include 4 kinds of cereals, eggs, goattan, vegetables and fruits, and if you don't have time to prepare them, you can also include 3 kinds.

For example, eat an egg, a slice of whole wheat bread, drink a glass of milk, and eat a banana for breakfast, so that the nutritional mix is more comprehensive and rich.

Second, lunch is more important in the three meals a day, it is in the middle of breakfast and dinner, in the middle of the day, and has the function of connecting the previous and the next. While ensuring nutrition, lunch should consume enough energy, that is, eat enough at lunch. A nutritious lunch should include cereals, vegetables, and meat.

If you pay attention to health, you can use multigrain rice instead of rice, choose green leafy vegetables for vegetables, mainly fish and chicken, and eat less pork, mutton and other red meat. Lunch should still be full, otherwise it will not be enough to support an afternoon of work or study.

Thirdly, eat a light dinner! The most important principle of dinner is to be light, never eat too greasy, otherwise the burden on the digestive system will be strengthened, and excessive calories will be converted into fat, making the human body obese. But dinner can not be eaten, many people will choose to skip lunch to **, in fact, there is no scientific basis, the harm to the human body is greater.

Dinner should be eaten sparingly, but it should not be avoided, and the choice of meal type should also be among cereals, vegetables, mushrooms, and meats, and you should mix them according to your preferences. Many people will choose to party after work in the evening, so that they will eat more greasy, in fact, do not do this often, because it has a great impact on digestive health.

What is malnutrition? Only humans can say that. Other animals don't have the same concept.

Each animal has its own unique digestion and absorption system, has its own eating habits, and has its own way of adapting to nature. Dogs are said to love to eat meat, while dogs have comparatively short intestines. The meat stays in the dog's intestines for a short time and is quickly excreted, so it is not enough for the dog to eat.

I forgot to see it in **, but it is said that herbivores have long intestines and carnivores' intestines are short.

<> people eat animals and plants, eat both meat and grain, pay attention to nutrition, and if they eat partially, they will be malnourished. When other animals themselves are not so particular, humans can help them to be exquisite, so that the animals can eat well. I once raised two discarded chickens, put them outside the fence of the balcony, and gave the leftovers at home to the baby to eat, the chicken baby grew so fast, every time I fed, I found an interesting thing, the chicken baby found that there was meat in the leftovers, so I picked meat to eat, but I don't like to eat meat, and the chicken baby helped.

The two chickens soon grew into big broilers, and they couldn't be kept at home, and they couldn't bear to let their families eat them, so they only argued that they were sent to their hometown to deal with them. Yuanzao wide chickens also eat meat, but who usually feeds the chickens, it will not be too costly. So, we don't care what the animals eat.

What's even more interesting is that most animals in the world have the ability to synthesize vitamin C, and humans are one of the few unfortunate species. This ability is lost because it was readily available in the diet of our ancestors. So in general, eating only one type of food is not a big problem, but there are also significant food security risks, such as the Irish famine in the mid-19th century, which was caused by over-reliance on potatoes.

Don't put all your eggs in one basket.

Do a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me more, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

It will definitely lead to malnutrition, because we are omnivores, and we must eat a lot of things, and if we only eat one kind of food, it will lead to malnutrition, and then we will also let our body be ruined and sick.

Absolutely. Eating a food often can lead to malnutrition, which can also lead to incomplete nutrition, and in severe cases, it will lead to a decrease in immunity and lead to disease.

Because our body needs a lot of complex vitamins and proteins, no food can contain a wide variety of vitamins and proteins.

It can lead to malnutrition, because if you eat only one type of food, the amount of nutrients in your body is very small, so it will eventually lead to anemia.

Yes, because there are great limitations to the nutrients provided by one food, eating only that food can easily lead to malnutrition.

Yes, because the nutrients provided by a food are very limited, and eating only this kind of food can easily cause malnutrition.

The human body needs more than 40 kinds of balanced nutrients to maintain the normal functioning of the body. Once the diet is unbalanced, picky eating, picky eating, poor lifestyle, it is easy to cause nutritional imbalance, then it is important to supplement nutritional supplements.

Reason 1: Reduced nutrients in food. The heavy use of chemical fertilizers, indoor cultivation, early harvesting and storage time have caused food to lose a lot of nutrients, and although we have eaten vegetables and fruits, we have not taken many vitamins and minerals.

Reason 2: There is an increase in harmful substances in our lives. The living environment is full of many harmful substances, such as pesticides in food, ultraviolet rays in the air, harmful heavy metals and chemicals in the soil, which will harm the human body and quickly consume nutrients in the body.

Reason 3: Life stress. Chinese are a group of people who work long hours and are stressed in the world, and long-term stress can affect the immune system or autonomic nervous system.

This is well known, for example, stress causes gastritis, creating a vicious cycle of inability to absorb calcium or other nutrients. To cope with stress, a lot of zinc, magnesium, pantothenic acid, vitamins are consumed in the body.

Reason 4: The frequency of eating out is increasing. The busy lifestyle of modern people greatly increases the probability of eating out. In addition, excessive intake of oil and salt caused by eating outside can easily cause the decline of physical functions.

Reason 5 Improper food handling. During the process of food processing, such as washing, cutting, cooking, etc., it is easy to cause the loss of nutrients, especially water-soluble vitamins are easy to be lost in excessive washing.

Reason 6 Picky eating and poor eating habits. Poor eating habits and preference for certain foods can easily lead to unbalanced nutrient intake.

Reason 7: Special illness or health condition. If the gastrointestinal system is not good, it will directly or indirectly affect the digestion and absorption of nutrients. People who do not absorb well in Xiaohua, even if they eat too much, may not be able to meet the needs of the body, so they need to make appropriate supplements.

Reason 8 Bad habits. Smoking, staying up late, drinking, and eating supper make the body in a state of fatigue, which will reduce and hinder the absorption of nutrients, and easily cause nutrient loss and nutritional deficiencies.

Reason 9 Different age and gender have different nutrient needs. Each age group, gender, and nutrient needs are different, and appropriate adjustments should be made according to the different needs and health conditions of individuals to maintain their health needs.

Due to the various lifestyle habits and irregular diets of today's people, it is difficult for us to obtain balanced nutrition in our usual diet. Here, it is recommended that you supplement some basic nutritious foods in moderation.
