Cancer is a space-occupying lesion, which refers to a local mass formed by the abnormal proliferation of local tissue cells in the body under the action of various tumorigenic factors.
Generally, tumors can be divided into benign tumors and malignant tumors based on their pathological morphology, degree of differentiation and maturity, growth pattern, and degree of harm to patients. Benign tumors are collectively called tumors, and malignant tumors are collectively called cancer.
Carcinoma is a malignant tumor originating from epithelial tissue, and sarcoma is a malignant tumor originating from mesenchymal tissue. Cancer in the popular sense actually refers to all malignant tumors.
Cancer is the biggest "enemy" in the history of human resistance. Although the current medical level has advanced by leaps and bounds, many stubborn cancers still cannot be completely cured, especially patients with advanced cancer. The torture of pain, the pain of treatment, and the huge trauma suffered both physically and mentally.
I believe that most people "talk about cancer in disgrace". It is precisely because of the horror of cancer that people are becoming more and more aware of cancer prevention, so that various kinds of cancer will appear every once in a while. Various anti-cancer foods, such as sweet potatoes, dandelions, etc., which have been widely circulated on the Internet.
However, many food rumors have been refuted one after another. Recently, a new anti-cancer food has begun to circulate on the Internet, that is, lettuce. The reason is that lettuce is rich in antioxidants-aromatic hydrocarbons. So Is there any scientific basis for this statement? Next let’s find out together.
01
Is lettuce the new “anti-cancer food”? Can it really kill cancer cells?
Among the 26 anti-cancer foods recently published by the American Institute for Cancer Research, lettuce ranked second, but this does not mean that eating lettuce can prevent cancer.
Experimental research only extracts a certain component from lettuce, and this component has anti-cancer effects in animal experiments, but it does not mean that eating lettuce can achieve anti-cancer effects. .
Moreover, the antioxidant content in lettuce is limited. To reach the concentration required for the experiment, one would have to eat several kilograms or even dozens of kilograms at a time, which is obviously unrealistic.
02
Although lettuce does not fight cancer, proper consumption can bring benefits to the body
It can calm the nerves and help sleep
Modern research also It has been found that eating lettuce in moderation can also help people reduce stress in life, is good for sleeping at night, and has a certain soothing and sleep-inducing effect. This may be related to the B vitamins and inulin substances.

The crisp texture and slightly bitter taste of lettuce can stimulate the secretion of digestive enzymes and enhance people's appetite. In addition, the milky white slurry in lettuce can stimulate gastric juice, digestive glands, The secretion of bile helps gastrointestinal digestion.
Hematopoiesis and replenishing blood
Lettuce contains a variety of vitamins and minerals, which can regulate the function of the nervous system. The organic content contained in it is rich in iron that can be absorbed by the human body. It is very beneficial for patients with iron deficiency anemia.
03
Reminder: Don’t eat lettuce indiscriminately, it may not be suitable for these three types of people
1. People with gastrointestinal diseases
If you suffer from gastrointestinal diseases, such as duodenal ulcer, gastric ulcer and other diseases, lettuce has a cool nature and is rich in plant fiber. Excessive consumption of lettuce may cause a burden on the gastrointestinal tract, and in severe cases may cause gastrointestinal discomfort, which may aggravate the condition, and may also cause abdominal pain, nausea, vomiting, loss of appetite and other symptoms.

Some substances in lettuce may cause optic nerve stimulation. If you eat too much lettuce, you may feel dizzy or drowsy, which is mild. The poisoning reaction may even induce night blindness. If people with eye diseases often eat lettuce, it may aggravate night blindness or induce other eye diseases.
3. Menstruating women
Although lettuce tastes good, it is a cold food, so it is not suitable for menstruating women, especially cold lettuce, which can easily lead to irregular menstruation and irregular menstruation. Aggravate the symptoms of dysmenorrhea.
