According to statistics, stomach cancer patients in China account for about 40 per cent of the total number of stomach cancer patients in the world; it is expected that by 2015, the incidence rate of stomach cancer in China will also climb by 1.6 per cent per year. Experts said that stomach cancer was originally a prevalent disease among people over 50 years old, but in recent years, the number of cases among young and middle-aged people has increased. In addition to irregular dietary habits, lack of sleep and excessive pressure have also become triggers for young people to develop stomach cancer.

　　Love to eat salted fish and other pickled products are prone to stomach cancer.

　　Stomach cancer can occur at any age, but the general trend is that the incidence rate rises with age, and the peak age of incidence is between 40 and 69 years old. However, in recent years, the incidence rate of stomach cancer among young and middle-aged people has been increasing rapidly. According to some data, in the past five years, the incidence rate of stomach cancer among young people between 19 and 35 years old has doubled compared with that of 30 years ago.

　　The occurrence of stomach cancer is not related to diet, experts said, such as the love of eating pickled food, salted fish and so on have a certain relationship. In addition, often eat fried food, irregular diet, Helicobacter pylori infection is also a cause of stomach cancer. Special reminder, the weather in the south, heavy moisture, food easy to mould, mouldy food in the aflatoxin is a strong carcinogen, so usually pay attention to do not eat mouldy food.

　　Lack of sleep makes stomach cancer approaching young people

　　Experts said, "In addition to irregular diet, stress is also a major cause of stomach cancer in young people." Nowadays, young people often solve three meals a day in restaurants, barbecue food, spicy and heavy taste, high salt and high calorie, smoking and drinking and other bad lifestyles will destroy the normal function of gastrointestinal tract, damage gastric mucosa, leading to gastritis, gastric ulcer and other diseases, and increase the chance of cancer. And high mental stress aggravates the dysfunction of the digestive system.

　　In addition, long-term staying up late and lack of sleep are also one of the causes of stomach cancer in young and middle-aged people.

　　Diversified food for stomach cancer prevention

　　Diversify food and maintain a balanced diet. Avoid diets that are high in salt (the amount of salt should be limited to 10 grams per day), too hard and too hot. Drinking strong alcohol can also damage the gastric mucosa and induce stomach cancer, which should be avoided.

　　Eat foods with protective effects appropriately. Choose foods rich in vitamin E, such as almonds, hazelnuts, peanuts and vegetable oil. Garlic can inhibit the growth of nitrate-reducing bacteria and moulds in the stomach and should be advocated to be eaten more often. Non-smoking can reduce the content of thiocyanate, the catalyst of nitrosation reaction, in the body, thus reducing the synthesis of N-nitroso compounds.

　　Eat less or do not eat carcinogens, N-nitroso compounds and other carcinogens are factors that induce gastric cancer, people should eat less or do not eat food related to it, such as pickled, smoked, grilled, baked, fried food and mouldy food.
