People take food as their day, no matter whether they are rich or poor, no matter how busy and idle, they can't do without three meals a day every day. With the continuous improvement of living standards, people's requirements for eating are getting higher and higher, and now eating is not only limited to satiety, but also has both flavor and nutrition. Protein, vitamins, minerals, etc. should be included in every meal to achieve a balanced nutrition. Therefore, in our kitchens, we often have to prepare a variety of ingredients to meet our nutritional needs. Among them, vegetables are an indispensable category, every meal must be involved, vegetables can provide us with a variety of vitamins, trace elements, dietary fiber and other ingredients, regardless of spring, summer, autumn and winter, if you want to maintain good health, want to satisfy your taste buds, you can't miss vegetables.
Vegetables are the representative of nutrition and health, some vegetables can not only be fried and eaten, boiled soup to eat, but also can be eaten raw, many people feel that eating raw is more conducive to the preservation of nutrition, buy home and wash and eat it. In fact, vegetables can not be eaten indiscriminately, because some vegetables have a special growth environment, in the process of growth, it is not only easy to attract insects, attached to ash impurities, but also easy to breed bacteria, parasites, and these are often difficult to see with the naked eye, simple cleaning can not be removed, even with boiling water can not be scalded, if it is eaten raw, it will inevitably make parasites enter our body, thereby affecting our health. Here are 5 common vegetables that contain a lot of "parasites", don't be careless before eating, the consequences are very serious, don't take it seriously.
1. Callus white
It has a long history of cultivation in China and is one of the common aquatic vegetables. However, in the early days, people used the seeds of the white water as food and listed them as one of the "six grains". Later, by the parasitism of powdery mildew, the plant can no longer be tasseled and flowered, and the stem tip forms a deformed and hypertrophic gall, which is found to be delicious, so it is eaten as a vegetable, which is now the white of the cocoon.
Nowadays, it is planted in the north and south of the great rivers in China, and generally grows in fresh water such as the Yangtze River. After peeling off the skin, it can be eaten raw, and its texture is crisp and fragrant, but it is best not to eat it raw. Because of the long-term growth in the water, it is easy to attach to the ginger fasciola, which is a common aquatic parasite, which enters the human body through aquatic plants as the transmission medium, and likes to parasitize in the small intestine, thus affecting human health. Therefore, it is important to cook it thoroughly before eating it. In addition, it is also a vegetable that contains a lot of oxalic acid, so it should be blanched before cooking.
2. Lotus root
Autumn and winter are the seasons to eat lotus root, which has high nutritional value, helps to moisturize and reduce dryness, strengthen the spleen and stomach, and enhance physical fitness. Fresh lotus root can also be eaten raw, and it is sweet, juicy, crisp and fruit-like. However, we still have to avoid eating it raw. Since ancient times, people have described lotus flowers as "out of the mud without staining" to symbolize the noble character of not being in the same stream as the world.
However, the lotus root that grows under the lotus flower has been buried deep in the silt, and in some areas, in order to increase nutrients, manure will be used to plant lotus root, so the lotus root is not only covered with soil, but also absorbs more parasites, such as schistosomiasis, ginger fasciola, etc. Therefore, before eating, the lotus root must be peeled and washed, and then after a long time of high-temperature cooking, it can be boiled, fried, steamed, etc., so that it is more hygienic to eat.
3. Horseshoe
This season is also the time when horseshoe is abundant and is known as the "underground fruit", which is sweet, juicy and crisp when eaten raw. In addition, horseshoe helps to moisten the lungs and relieve cough, so it is loved by people in winter. However, horse hooves must be carefully processed before eating, and they must not be sloppy.
Horseshoe likes to be wet and often grows in swamps and paddy fields, so the horseshoe we see in the supermarket is generally covered with mud, of course, some will be washed in advance before being sold, but it is inevitable that the surface will be wet. During the whole growth process of horseshoe, it is easy to breed bacteria and ginger fasciola, so it is best not to eat it raw, let alone gnaw the skin with your mouth. Be sure to cook it at high temperatures before eating.
4. Broccoli
Broccoli is a very nutritious vegetable, which contains a lot of vitamin C, dietary fiber, sulforaphane, folic acid, cellulose and other components, which help protect the heart, improve eyesight, enhance resistance, beautify and moisturize, etc. Although broccoli is healthy and nutritious, it is actually a test of patience when handling it. Its special physiological structure makes it easy to breed bacteria, insects, etc., although pesticides will be sprayed in the process of its growth, but we often see some insects, eggs, etc., and there may be some parasites that we can't see. Therefore, after the broccoli is washed, it should be blanched in boiling water before cooking.
5. Lettuce
Lettuce is a vegetable that mainly uses the root as the main edible part, and the ancients praised its high nutritional value as "golden vegetable". Lettuce is rich in water, folic acid, potassium, vitamins, fiber, etc., which help maintain intestinal health, strengthen bones, and enhance immunity. The lettuce is moist and juicy, and many people like to eat it cold and raw, which is very appetizing and delicious.
However, the environment in which lettuce grows for a long time is also relatively humid, especially in the underground part, which is easy to breed bacteria and parasites, so when handling lettuce, it is necessary to wash it carefully and peel the skin clean. It is then cooked at high temperatures before eating. In addition, lettuce itself also contains a certain amount of oxalic acid, so even if it is cold, it is best to boil it in boiling water first, which is more conducive to nutrient absorption.
