1. The "Soup Stomach": People who habitually drink large amounts of soup on an empty stomach quickly fill their stomach with liquid. Due to the long-term lack of staple foods such as grains, their stomach qi weakens, leading to stomach problems. Many white-collar workers often have soup as a meal, and as a result, they frequently feel a bloated, uncomfortable sensation in the upper abdomen—neither truly hungry nor full. This group can steam or cook dark tea together with food to make delicious tea-infused dishes, which not only enhances appetite but also allows absorption of the nutrients in dark tea. Dark tea is rich in nutritional components, most notably vitamins and minerals, as well as protein, amino acids, and carbohydrates. Long-term consumption of dark tea serves as an important source of essential minerals and various vitamins for the human body.

2. The "Smoke Stomach": These are people who develop stomach problems from smoking. In social settings, white-collar workers often offer cigarettes as a gesture of hospitality, and many mental workers also like to light a cigarette while thinking to relax or "stimulate inspiration." Over time, they lose control and unconsciously smoke more and more, causing varying degrees of damage to the gastric mucosa, eventually leading to gastritis, ulcers, and other conditions. This group can drink dark tea one to two hours after breakfast. Over time, this can help reduce the harm of tobacco toxins to the body. The tea polyphenols in dark tea can cause nicotine to precipitate and be excreted in urine. They can also scavenge free radicals in cigarette smoke, reducing its toxic effects on the body. For heavy metal toxins, tea polyphenols have a strong adsorption effect, so drinking more tea can also alleviate the toxic effects of heavy metals.

3. The "Alcohol Stomach": Drinking at banquets and social events is an important part of work and life for white-collar workers. When raising glasses in celebration, the idea of protecting the stomach often evaporates with the alcohol. By the end of the drinking, they often feel a dry mouth, bitter taste, a burning sensation in the stomach, and the onset of stomach pain. The diuretic effect of caffeine in dark tea works by promoting the filtration rate of water in the urine through the kidneys. At the same time, caffeine's stimulating effect on the bladder aids diuresis and helps with sobering up and relieving alcohol poisoning. This group can drink a cup of dark tea, which can help detoxify and sober up. High blood lipid levels cause lipids to deposit on blood vessel walls, leading to atherosclerosis and thrombosis. Dark tea has good effects in degrading fat, resisting blood coagulation, promoting fibrinolysis, and significantly inhibiting platelet aggregation. It also relaxes blood vessel walls and increases the effective diameter of blood vessels, thereby inhibiting the formation of atherosclerotic plaques in the aorta and coronary arteries. This helps lower blood pressure, soften blood vessels, and prevent cardiovascular diseases.

4. The "Stress Stomach": During economic downturns, white-collar workers face even greater work pressure and are busier. To achieve good results, their three daily meals are often irregular, which can easily lead to stomach disorders. This group can choose to drink a cup of dark tea after dinner each evening, which can help calm the mind and promote sleep. The catechins, theaflavins, theanine, and tea polysaccharides in dark tea, especially the abundant complex flavonoids, have the ability to scavenge free radicals, thus providing antioxidant effects and delaying cell aging.

5. The "Late-Night Stomach": Even if it's not due to work, white-collar workers like to stay up late playing until very late before sleeping. This bad lifestyle habit can easily lead to imbalanced gastric acid secretion, and over time, stomach problems develop. This group can choose to drink a cup of mild ripe dark tea around 3 PM each day. Ripe dark tea has a protective effect on the gastric mucosa. The caffeine, vitamins, amino acids, phospholipids, and other components in dark tea aid digestion and regulate fat metabolism. The stimulating effect of caffeine further increases gastric juice secretion, thereby improving appetite and helping digestion.

6. The "Junk Food Stomach": When busy, white-collar workers not only eat irregular meals but also eat whatever is available. When hungry, they eat anything to fill their stomachs—sour, spicy, fried, raw, cold, salty, or fermented foods, as well as cigarettes, alcohol, strong tea, coffee, and even all kinds of nutritionally poor junk food. This can eventually lead to gastric cancer. This group can choose to brew a pot of dark tea in daily life, which helps cleanse the intestines and stomach while also nourishing and protecting the stomach. Dark tea can also improve the intestinal microbial environment and has a soothing effect on the gastrointestinal tract. In China, there is a folk tradition of using aged dark tea to treat abdominal bloating, dysentery, and indigestion.
