The main results suggest that there is no significant correlation between coffee consumption (with or without caffeine) and the occurrence of colorectal cancer. may have a certain preventive effect, especially for rectal cancer.

Coffee-acid related diseases (peptic ulcer, gastroesophageal reflux)

It is written in the textbook that foods such as fat, chocolate, tea and coffee can reduce LES stress and should be properly restricted. The results of a 2013 study of 8013 people suggested that coffee (with or without caffeine) was associated with acid-related diseases (digestive tract ulcers and esophageal reflux-related diseases) compared with those who drank less than one cup of coffee a day. There is no protective and no significant pathogenic effect.

Coffee-esophageal cancer

For male smokers, drinking caffeinated coffee above 447ml every day has a certain protective effect on the occurrence of esophageal squamous cell carcinoma.

Coffee-gastric cancer

There was no significant correlation between coffee and the occurrence of gastric cancer (fundus or non-fundus).

Coffee-liver cancer

Coffee drinking is highly regarded because of its relatively positive findings for liver disease. Compared with those who did not drink coffee, the risk ratio of liver cancer after drinking 2-3 cups of coffee per day was significantly lower than 1, which was statistically significant.

Coffee-acute pancreatitis

Coffee is not a possible factor for acute pancreatitis, on the contrary, it has a significant protective effect on non-cholelithiasis-related acute pancreatitis.

Coffee-pancreatic cancer

With regard to the prevention and treatment of digestive tract diseases, in addition to improving eating habits and living habits, taking drugs and regulating mood, it can also be solved by adding an appropriate amount of probiotics. Probiotics in the stomach can secrete acidic substances, regulate gastric acid secretion, prevent excessive erosion of gastric mucosa, regulate the secretion of immune factors in gastrointestinal mucosa, improve the immune defense function of gastrointestinal tract, and competitively inhibit the growth and reproduction of Helicobacter pylori. Secretion of antibiotics destroys the ammonia layer of Helicobacter pylori, makes it unprotected, and is killed by gastric acid. Bring natural biological enzymes that the human body does not have, and break down food that its own enzymes cannot digest. Timely supplement of probiotics can protect and repair gastric mucosa, heal gastric ulcer and strengthen gastric immunity, so as to prevent and treat gastric motility deficiency.
