Drinking coffee every day reduces the risk of colon cancer recurrence

Coffee is a caffeinated beverage made from roasted coffee beans. It is one of the most popular drinks in the world along with cola and tea. Whether coffee affects health has always been a topic of great concern to many people, and scientists have been debating it for many years.

Recently, scientists from the Dana Farber Cancer Center in the United States conducted a study and found that daily consumption of caffeinated coffee can help prevent the recurrence of colon cancer after treatment and increase the chances of colon cancer being cured. The relevant research results are published in the international academic journal Journalofclinicaloncology.

The study involved nearly 1000 patients with colon cancer, and the researchers surveyed their coffee drinking habits during the early stages of the study and a year later. The results showed that among the colon cancer patients with stage III who received surgery and chemotherapy, patients who drank more than four cups of coffee (about 460mg caffeine) a day benefited the most, with a 42 per cent lower risk of cancer recurrence and a 33 per cent lower risk of death from cancer or other factors than those who did not drink coffee. The benefits of drinking two to three cups of coffee a day were moderate, while those who drank only one cup of coffee or no coffee a day did not.

The researchers point out that although this study shows that drinking coffee can help prevent colon cancer recurrence after treatment, other studies are still needed to further verify the results, otherwise no guidance can be given to patients. Patients with coffee drinking habits who are being treated for colon cancer should continue this habit, but if the patients are not in the habit of drinking coffee, whether they should start drinking coffee or not, you still need to communicate with your attending doctor before making a decision.

High fiber + low fat = low incidence of colon cancer?

There is a western proverb called "Wearewhatweeat." There is also a saying in some parts of China that "what you eat is what you eat". Are these claims strictly valid in science? At least we haven't seen any very rigorous evidence yet. However, scientists have proved that diet does affect people's health and even their physical appearance in many ways.

The recent "NatureCommunications" research highlight column commented on the research article entitled "Fat,fibreandcancerriskinAfricanAmericansandruralAfricans". According to this review, American scientist StephenO'Keefe and his colleagues have shown that in black people, the incidence of colon cancer can be significantly reduced by reducing the amount of fiber and fat in the diet.

Colon cancer is the second most fatal type of cancer in western countries. Black Americans, on the other hand, have the highest incidence of cancer deaths. By comparing the dietary composition differences between 20 Native African blacks living in rural areas and 20 African-American blacks, the researchers found that Native African blacks had higher levels of plant fiber and other carbohydrates. Black Americans seem to eat better, with two to three times more animal fat and protein than African blacks. At the same time, tests of their intestines found that a higher proportion of colon cancer-related biomarkers were detected among black Americans.

In addition to the differences in the molecular weight of colon cancer biomarkers, the researchers also found differences in their intestinal microflora. There are a large number of microbes in the intestines of the African black population that ferment carbohydrates and synthesize butyrate (one of the products of fat decomposition). For black Americans, they have more bile salt (the main component of bile, which is good for fat digestion) metabolism-related microbes in their intestines. Available evidence can prove that plant fiber fermentation can inhibit the occurrence of cancer, however, on the contrary, excessive bile salt is one of the causes of cancer.

Then, the scientists exchanged food for two weeks between the two groups and found that two weeks after black Americans ate foods high in fiber and low fat, the type of microbial population changed and the molecular markers associated with colon cancer decreased. This is effective evidence that a high-fiber, low-fat diet can reduce the incidence of colon cancer. Of course, critics say longer-term research is necessary.

Although the study is aimed at black people, it may also have implications for other groups.
