Just as most people around us care only about how high we fly, few ask if we're tired. The same goes for our stomachs: we treat them like mere vessels for food and drink, scheming to stuff them with more fine wines and delicacies, yet seldom consider if they can handle it.We rush about in a daze, forgetting it entirely until mealtime has long passed. We crave spicy, smoked, and grilled foods, forcing it to accept them unconditionally. We starve ourselves for a slender figure, yet it suffers alongside us—corroded by stomach acid. This cycle repeats, our selfishness inflicting deep wounds upon our stomachs.
Data reveals that among China's 1.3 billion people, 120 million suffer from gastrointestinal disorders. The incidence of peptic ulcers stands at 10%, while chronic gastritis affects 30% of the population, making China the undisputed "world leader in stomach ailments." Additionally, China is a high-risk zone for gastric cancer, with 400,000 new cases diagnosed annually—accounting for 42% of global gastric cancer patients.Please treat your stomach kindly, or it will protest: bloating like it's stuffed with cotton, constant belching, and sudden, excruciating pain. Have you ever done any of these stomach-damaging habits?
1. Irregular meals, excessive stress, preference for smoked foods, and consuming scalding hot food may cause cancer
Studies indicate that individuals with irregular meal times face a 1.3 times higher risk of gastric cancer than the general population. Eating while angry increases the risk by 1.5 times, while a preference for extremely hot food raises it by 4.22 times. The relative risk of gastric cancer is significantly higher when these factors occur concurrently.Zhang Ye explains that the stomach is an organ that follows a strict "schedule." Gastric acid secretion follows natural peaks and troughs throughout the day to facilitate timely digestion.Without food to neutralize them, stomach acid and pepsin can digest the stomach lining itself, causing damage. Skipping breakfast, binge eating, irregular meals, pulling all-nighters, and an erratic lifestyle create fertile ground for gastric cancer.
Processed meat products like cured meats and smoked fish contain high levels of nitrites, which readily form nitrosamines. These compounds directly induce tumors in the stomach, explaining the high incidence of gastric cancer in coastal regions and among the Japanese population.Swedish scientists found that for every 30-gram increase in daily processed meat consumption, the risk of stomach cancer rises by 15%–38%.
Furthermore, the digestive tract's mucous membrane is extremely delicate, tolerating only foods between 50–60°C. Temperatures exceeding this range cause burns to the mucosa.Freshly brewed tea, for instance, can reach 80–90°C, easily scalding the digestive tract. Frequent consumption of excessively hot foods causes repeated damage and repair cycles to the mucosa. This cycle of injury and recovery can alter the mucosal tissue, potentially leading to cancerous changes.
Expert advice: For those unable to eat meals on time, keep snacks like soda crackers or instant oatmeal readily available. Even when rushing, consume something to counteract stomach acid and prevent the stomach from "running empty." However, this should only be an occasional solution—long-term reliance can still harm the stomach. Those who enjoy smoked foods should reduce consumption frequency, limiting it to occasional treats.When grilling or smoking foods, avoid direct contact with flames, limit cooking time, and never consume charred portions—the proteins in these areas have denatured. Additionally, when enjoying grilled foods, pair them with vitamin C-rich vegetables and fruits to help counteract carcinogens.
II. Gastric Ulcers Caused by Hard Liquor, Unsanitary Food, and Medication Irritation
Smokers often believe nicotine only affects the lungs, unaware that smoke also enters the stomach via the digestive tract. This directly irritates the gastric mucosa, causing vasoconstriction and spasms in the submucosal blood vessels. Over time, this leads to ischemia and hypoxia in the gastric mucosa, easily resulting in gastric ulcers.
Moderate consumption of low-alcohol beverages can increase gastric blood flow. However, prolonged or heavy intake of strong spirits directly damages the gastric mucosal barrier, causing congestion, edema, erosion, and even bleeding.
Helicobacter pylori is a major culprit in gastric ulcers, with infection often stemming from contaminated food or person-to-person transmission.
Many medications, such as antipyretic analgesics and anti-inflammatories (aspirin, paracetamol, painkillers) and glucocorticoids (dexamethasone, cortisone), can directly or indirectly damage the gastric mucosa. They increase gastric acid and pepsin secretion, causing inflammation and ulcers. In severe cases, gastric bleeding and perforation may occur.
Expert advice: Moderate consumption of low-alcohol beverages like rice wine or wine is acceptable, but avoid excessive consumption of spirits and never drink low-quality alcohol. Eat a light meal before drinking to reduce direct irritation to the gastrointestinal tract. Separate meals can lower the risk of Helicobacter pylori infection. This practice is especially crucial when household members have gastric ulcers.Avoid indiscriminate medication use. When taking long-term medications that irritate the stomach, it's best to take gastric mucosal protectants.
III. Eating While Walking or Reading Causes Indigestion
To save time, many people eat breakfast on their way to work and often eat lunch while reading books or staring at computer screens. This causes significant discomfort to the stomach.Digestion is a demanding process requiring ample blood supply. Physical activity during meals significantly diverts blood flow from the gastrointestinal tract, impairing normal digestive function and potentially leading to gastritis or even gastric ptosis. Similarly, multitasking while eating causes the brain to compete with the digestive system for blood flow, resulting in poor digestion.
Expert advice: Wake up 15–20 minutes earlier each day. After getting out of bed, sit down calmly for breakfast half an hour later. Focus your attention on your food during meals—chew thoroughly, savor each bite, and enjoy your food. This is the way your stomach prefers to be fed.
IV. Soup-soaked rice and excessive spice burden the digestive system
Some people enjoy mixing rice with soup to create "soup-soaked rice." This practice causes food to slide into the stomach before being properly chewed in the mouth, increasing the burden on the digestive tract. Additionally, eating soup-soaked rice reduces saliva secretion, hindering digestion and preventing full nutrient absorption.Furthermore, insufficient stimulation of taste nerves reduces digestive fluid secretion, ultimately leading to gastrointestinal dysfunction, poor digestion, and malnutrition.
Moderate spice consumption can boost health, but excessive heat triggers excessive digestive fluid secretion, causing mucosal congestion, edema, and accelerated gastrointestinal motility.
Fried foods, being relatively hard in texture, are difficult to chew thoroughly and mix evenly, hindering their digestion in the stomach and small intestine. After frying, most particles become coated in oil, reducing contact with proteins or starches. This makes them harder to digest, increasing the burden on the digestive system and potentially causing discomfort like acid reflux or nausea.
Expert advice: Consuming soup-soaked rice regularly is inadvisable. When eaten occasionally, chew thoroughly and slowly to reduce digestive strain. Ideally, replace this habit with drinking soup or congee before meals. A small amount of soup before eating not only moistens the mouth and esophagus but also stimulates saliva and gastric juice production, aiding digestion.After prolonged boiling, congee softens the rice grains and breaks down starch into dextrin, which is easily absorbed by the digestive system and does not impair digestion. For those who enjoy spicy foods, drinking a glass of milk beforehand can protect the stomach lining. Individuals with sensitive digestive systems or internal heat who find spicy foods irresistible should opt for mildly spicy options.
5. Eating acidic fruits on an empty stomach can cause bloating
When the stomach is empty, gastric acid concentration is higher. Consuming large amounts of acidic fruits at this time causes the stomach acid to react with components in the fruit, forming insoluble precipitates. Once these precipitates clump together, they increase pressure inside the stomach, leading to bloating, acid reflux, and a series of uncomfortable reactions and digestive disorders.For example, persimmons contain persimmon tannin, pectin, tannic acid, and anthocyanins. Eating them on an empty stomach can easily cause "gastric persimmon stone syndrome." Hawthorn berries are sour and can promote digestion, but eating too many on an empty stomach can actually increase hunger and aggravate stomach conditions.
Expert Advice: Individuals with gastric or duodenal ulcers, or excessive stomach acid, should avoid highly acidic fruits like hawthorn, lemon, bayberry, and plum. These can increase gastric acid secretion, irritate the stomach lining, and hinder ulcer healing.
