As the saying goes, illness from the mouth, unhealthy eating habits, may induce the emergence of physical diseases, thereby increasing the burden on the human body, leading to human discomfort.

So if you want to stay healthy, you should pay more attention to your diet. Some people think that they can't eat meat when they are old, so they should eat more fruits and vegetables, because in their eyes, eating more vegetarian food means being healthier.

According to the dietary guidelines of China residents, it is suggested that there should be vegetables in the meal, and the intake of vegetables, especially dark vegetables, should be at least half. In short, it is recommended that adults eat enough vegetables every day, that is, 500 grams, and children can be appropriately reduced according to their age.

It can be seen that increasing the intake of vegetables properly every day can really help the body to supplement multivitamins. Trace elements can enhance resistance and immunity and relieve constipation. However, not all vegetables are good for your health, especially the following vegetables. Please eat as little as possible. In order to stay healthy and stay away from diseases, I suggest you know as soon as possible.

First of all, let's understand why there are vegetables in the meal.

High vitamins:

Vegetables contain various vitamins needed by human body, such as vitamin C, vitamin B 1, vitamin B2, vitamin B6, nicotinic acid, carotene and so on.

In particular, vitamin C and carotene are particularly rich. In the current dietary structure, most of vitamins A and C needed by human body are provided by vegetables, which can effectively supplement nutrition and provide functions for human body.

High minerals:

Vegetables contain a variety of mineral elements, among which calcium, phosphorus, iron and potassium are very rich.

Whether for teenagers, children, middle-aged people or middle-aged and elderly people, eating more vegetables in life can also supplement various minerals and calcium, protect bone health, promote bone growth and development, and prevent osteoporosis.

High dietary fiber:

Vegetables are rich in cellulose and high in dietary fiber such as hemicellulose. Although cellulose can not be directly digested and absorbed by human body, its existence can accelerate the reaction of adding and subtracting cholic acid from cholesterol, thus reducing the incidence of cardiovascular diseases.

Escherichia coli can also use cellulose to synthesize gastric acid, nicotinic acid, oryzanol, alcohol, vitamins and biotin. If the food lacks cellulose, the synthesis of these vitamins will be hindered. Vegetables rich in dietary fiber can also increase intestinal peristalsis, relieve constipation and reduce the incidence of colon cancer.

1 Oenanthe javanica

Oenanthe javanica is similar to celery in our daily life in appearance, but it mainly grows in water and absorbs its nutrients, but because of the harsh living environment.

Especially in summer, insects and flies will breed around the roots, so this vegetable may contain a lot of parasites and harmful substances. After eating too much, human health may be affected and even pathological changes may occur, so please eat less of this food.

2 lettuce

Speaking of lettuce, it is also a very common food in life and a kind of lettuce that many friends like to eat. Crispy taste and rich nutritional value, especially when many people eat barbecue, they will also eat with lettuce, which will help to relieve boredom.

Because the growth structure of lettuce is wrapped in the heart, it is easy to mix with parasites and dirty things. So before eating lettuce, be sure to clean it thoroughly and blanch it in the pot before eating. This can reduce the residue of harmful substances, which is more conducive to the absorption of nutrients and human health.

3 lettuce

Essence is also a common food in life, and its taste is crisp. Whether eating hot pot or mala Tang, many people will order a plate of lettuce, which is particularly chewy, nutritious and contains a variety of carotene vitamins.

However, this kind of food is not recommended to be used frequently, because the growth environment of lettuce is in a humid underground for a long time, which is easy to breed bacteria and viruses.

If it is not thoroughly cleaned before eating, it will also lead to parasites entering the body and endangering health. Therefore, it is recommended that you eat lettuce as little as possible and wash it thoroughly before eating to avoid unnecessary harm to your body.

4 water spinach.

Speaking of water spinach, I believe everyone is familiar with it. Eating water spinach in this season can help the body to supplement vitamins, with a crisp and special taste and a cool feeling.

But it is not recommended that you eat too much, because there are many parasites and pesticide residues in spinach, so it is recommended that you clean it thoroughly before eating.

You can put water spinach in water, add two or three handfuls of flour, stir well, soak for about 5~ 10 minutes, soak out parasites and residues on it, then rinse it thoroughly with clear water and put it in a pot to start cooking, which can reduce the influence of harmful substances on the body.

These three parasites are often found in vegetables.

1, Fasciola hepatica

Fasciola hepatica likes to stay in the liver. Once the human body is infected with Fasciola hepatica, it will lead to the decline of liver function, and then there will be symptoms such as loss of appetite, abdominal distension and diarrhea, liver pain and even liver lesions.

2. anisole

The survival time of anisakis in human body is generally no more than three kinds, but if fish with larvae and undercooked fish are eaten by mistake, it may also cause anisakis infection. Once this symptom occurs, it will also lead to abdominal pain or allergies.

3. Clonorchis sinensis

Clonorchis sinensis is also called clonorchiasis sinensis. 70% of people infected with clonorchiasis sinensis have no obvious symptoms in the early stage, but this does not mean that he is powerless in the body. He hid in the biliary tract and secretly destroyed the health of gallbladder, liver, internal bile duct system and liver.

Within 0/~ 2 months after infection, symptoms such as poor appetite, nausea, unsafe upper abdomen, dull pain in liver area, diarrhea or constipation, inexplicable emaciation, physical weakness, etc. will occur, especially in children once infected.

* * In order to better remove parasites from vegetables, it is suggested that you soak the vegetables you bought in light salt water for a period of time, or soak a few handfuls of flour for about 5~ 10 minutes, and then wash them thoroughly with running water.

* * When cleaning, you can also apply detergent appropriately, and then rinse with flowing water.

* * In order to better reduce the appearance of parasites, it is suggested that you blanch vegetables with boiling water before cooking, so that some parasites can be eliminated without affecting the taste of vegetables.

* * Vegetables can also be soaked in baking soda water for about 5 minutes, and then washed with flowing water, which can also effectively eliminate some parasites and pesticide residues.

* * Finally, you can also choose to wash vegetables with Taomi water, which has a very good cleaning ability and can effectively remove pesticide residues on the surfaces of vegetables and fruits.
