The general dietary principle of stomach cancer is to use digestible food, rich in protein and fat, cooked rotten food, and try to reduce the content of crude fiber in food. It must be noted that rough food which is not easy to be digested can aggravate the patient's condition.　Common comorbidities of stomach cancer are: (1) Dumping syndrome: due to the loss of pyloric control over the stomach's ability to control food, after eating a large amount of food, it suddenly enters into the small intestine, which makes the patient feel fullness in epigastrium, discomfort, nausea, vomiting, dizziness, fatigue, sweating, palpitation, debility, blood pressure is slightly high, and bread is pale, which can be relieved by resting for 10-20 minutes in general. (2) Hypoglycemia: Due to the glucose absorption in the small intestine too fast after meals, causing temporary blood sugar increase, stimulating the pancreatic islet secretion increase, followed by the occurrence of hypoglycemia. The patient shows palpitation, dizziness, cold sweat and other symptoms, mostly occurring 2-3 hours after eating, a little food or drink some glucose water can relieve the symptoms. (3) Weight loss: As the stomach's content becomes smaller, it affects the stomach's feeding and digestive functions. Improper feeding can cause nutrient and calorie deficiencies, resulting in weight loss of the patient. (4) Anemia: Mostly seen in iron deficiency anemia, due to the reduced secretion of gastric juice and the reflux of intestinal fluids, which significantly reduces gastric acid and directly affects the absorption of oral iron, resulting in anemia. Reasonable meals can completely prevent the occurrence of the above comorbidities: 1) Eat less and have more meals, patients with gastric resection are recommended to eat less and have more meals, 6-7 times a day, and regular and quantitative meals can make the stomach not empty without using, and also can gradually adapt to the digestive function of the residual stomach. Eating less and more meals should be an important dietary system for patients after gastric cancer resection.2) Dividing dry and sparse food, in order to prolong the stay time of food in the stomach, eat only drier food and drink no water during meal time, and drink water after 30 minutes of meal time, so as to avoid the food from being rushed into the small intestine quickly, and to pass through the small intestine slowly, and to promote the further absorption of the food. 3)Limit carbohydrate intake to prevent dumping syndrome. 4) Gradually increase the amount of food and food types. Patients should gradually switch from postoperative fluids and semifluids to soft foods or ordinary meals, and increase the number of patterns according to the patients' dietary habits to improve their appetite and help them recover. (1) Eat more food that can enhance immunity and anti-gastric cancer, such as yam, lentil, Job's tear grains, loins, golden broccoli, shiitake mushrooms, mushrooms, sunflower seeds, kiwi, figs, apples, sardines, honey, pigeon's eggs, milk, pig's liver, sandworms, monkey head mushrooms, abalone, needlefish, sea cucumber, oysters, squid, shark, tiger fish, yellow swim bladder, seahorses, and beetles. (2) It is advisable to eat more high-nutrition food to prevent and control cachexia, such as black-boned chicken, pigeon, quail, beef, pork, rabbit, eggs, duck, tempeh, bean curd, silver carp, carp, swordfish, pond lice, mackerel, yellow croaker, squid, crucian carp, eel, pangolin, pomfret, loach, shrimp, tamarind, pig's liver, sturgeon. (3) Nausea and vomiting should eat Ulva, pomelo, orange, loquat, corn, walnuts, roses, poppies, figs, ginger, lotus root, pears, winter vegetables, mango, umeboshi, lotus seed.

(3) Avoid moldy, polluted, hard, rough, fibrous, greasy, sticky and indigestible food. (4) Avoid frying, deep-frying, smoking, pickling, raw food. (5) Avoid overeating, hardening and stuffing. The relationship between gastric cancer and diet and its prevention and treatment for readers' reference: the relationship between food and nutritional factors and the development of gastric cancer has been confirmed by epidemiology and animal experiments that the occurrence of gastric cancer has a very close relationship with diet and eating habits, which should not be underestimated. If you often eat cured food such as preserved meat and fish, although these foods are rich in protein, secondary amines are produced by protein decomposition in the process of preservation, and the less fresh the food is, the more secondary amines it contains. And cured meat, pickled fish, pickles (kimchi) sometimes also add coloring agent sodium nitrite, increasing the precursor substances of nitrosamine in the stomach easy to synthesize nitrosamine that can cause stomach cancer. Smoking, frying and baking, deep-fried food: after smoking and baking processed food inside can make the carcinogen 3 4 benzo(a)pyrene increase a lot. According to research analysis, 1 kg of smoked pork and beef contains BaP equivalent to the amount contained in 125 cigarettes, and fish frying for 2 to 4 minutes can increase carcinogenic substances by 4 times. Foreign data reported that Iceland residents to smoked beef and smoked fish as the main food, the local digestive tract cancer (mainly stomach cancer) incidence rate is three times higher than that of people in other places. The relative risk of gastric cancer is high among those who consume high salt: high salt can destroy the mucous membrane barrier of stomach, which makes cancerous substances easy to interact with gastric mucous membrane, therefore, the incidence of gastric cancer is related to the average daily intake of salt per person. Drinking strong alcohol can also destroy the gastric mucous membrane barrier and increase the incidence of gastric cancer. Smoking a lot of cigarettes (more than six cigarettes a day) can increase the thiocyanate in saliva and promote the synthesis of gastric nitrosamines. In addition, eating hot food and overeating can easily damage the gastric mucosa and induce cancer. Early Signals and Common Symptoms of Gastric CancerGastric cancer is a common malignant tumor, which occurs at the age of 50-60 years old, an important "juncture" for longevity, so it is a "roadblock" for human beings to enter into the old age. So, how to detect stomach cancer at an early stage? Stomach cancer is quietly mixed in many stomach diseases, and it is not easy to detect it at an early stage. Especially, the early symptoms of stomach cancer are similar to those of many stomach diseases, so even if you go to the doctor, you may not think of it as a cancerous tumor, thus delaying the condition and missing the time of early treatment. According to the research findings of medical doctors, the early signs of stomach cancer include: 1) inexplicable loss of appetite or discomfort in the upper abdomen; 2) frequent bloating in the upper abdomen, which needs to be relieved after repeated warming and is particularly obvious after eating; 3) irregular vague pain or short-term colic pain in the upper abdomen; 4) nausea, constipation or diarrhea after eating too much; 5) abnormal aversion to meat; 6) unexplained weight loss, tiredness; 7) mild symptoms that cannot be justified by any reason; and 8) a lack of appetite. 7, can not find a reason for mild anemia. These signals alternate repeatedly over a period of time, one or several of them. What's more, when these signals are found and mistaken for general gastric disease to take treatment, the symptoms are not relieved, you should be extra vigilant, may be stomach cancer! It is worth mentioning that, if a possible precancerous lesion such as chronic gastritis or gastric ulcer turns into gastric cancer, one of the obvious features of the early signals is that the pattern or symptoms of the original gastric disease has changed to a large extent. Common symptoms of stomach cancer include stomach pain, loss of appetite, emaciation and weight loss, nausea, vomiting, acid reflux, heartburn sensation, bleeding, black stools, diarrhea, etc. Patients with these symptoms should go to the hospital for examination and treatment in time. Dietary and nutritional prevention and treatment methods for stomach cancer Choose food to be fresh: try to buy, make and eat now to avoid the formation of nitrite affecting the health due to the instrument not being fresh or the leftover food being contaminated by bacteria overnight. Food preservation to the refrigerator is appropriate. Eat more fresh vegetables and fruits: because fresh vegetables and fruits are rich in vitamins A, E, K, C, folic acid and fiber.

Diet should be small and frequent, regular and quantitative, and it is not advisable to eat too much, which will increase the burden of stomach and intestines.
