Coffee Health Talk About Coffee and Cancer

Coffee and Cancer

Many studies on diet and cancer have shown that reasonable regulation of human diet and lifestyle can effectively reduce the incidence of cancer by 35%. About 109 million people in the world suffer from cancer every year, and 6.7 million people die of cancer, of which about 1 million are Europeans. It's not hard to understand that when we look at these numbers, we want to speculate about the relationship between our diet, living habits and the risk of cancer. Coffee, as a common drink, is certainly under study.

In 1991, the World Cancer Institute (affiliated with the World Health Organization) determined that coffee was "likely to cause bladder cancer", but because there was insufficient evidence at the time to prove that this claim did not give a more detailed analysis, and the report also concluded that coffee plays an active role in preventing some cancers. This conclusion has been studied many times since then.

Since 1991, many research data have focused on the relationship between coffee and the following four types of cancers: colon cancer, pancreatic cancer, bladder cancer and liver cancer.

Bowel cancer

The latest data show that 2/3 of bowel cancer can be prevented through reasonable diet and lifestyle regulation, but there is no food to protect humans from bowel cancer.

Several studies have found that drinking coffee can reduce the risk of cancer. Drinking more than five cups of coffee a day can reduce the risk of bowel cancer, according to a survey in Canada. Another study showed that people who drank more than four cups of coffee a day were 28 percent less likely to develop bowel cancer than those who drank less than one cup of coffee a day.

Similar studies on the role of coffee in reducing the risk of bowel cancer in humans have been shown in several trials in Asia, Northern Europe, Southern Europe and North America.

Although several of these studies have not reached this conclusion, they do not rule out other factors such as the effect of smoking on cancer prevalence.

How does it work?

Coffee helps reduce the elimination of bile acids, thereby reducing the risk of colon cancer. At the same time, coffee also contains some strong antioxidants, such as caffeic acid and chlorogenic acid, which are thought to have positive anti-cancer effects. And the coffee white fat contained in coffee also has an effective anticancer effect.

Pancreatic cancer

Most experts don't think there is a link between coffee and pancreatic cancer. Since the 1991 IARC report, several studies have come to conclusions. A survey of 17633 Americans, a survey from Norway, and three other studies: a survey of 14000 retired American citizens, a case study of nurses' health, and a follow-up study by the World Health Organization, all prove that coffee is not associated with pancreatic cancer.

A study a few years ago speculated that there might be a link between coffee, tobacco and pancreatic cancer, but did not produce exact data on coffee, but instead proved that drinking coffee in patients who already had pancreatic cancer could help alleviate the disease.

Bladder cancer

After the 1991 IARC report, many studies on coffee and bladder cancer have been carried out. These studies aim to determine whether coffee is a cause of bladder cancer and whether smoking is a cause of bladder cancer.

In a survey of 10 non-smokers in Europe, coffee consumption was not associated with cancer rates. A Norwegian survey of heavy coffee consumption and cancer risk was also inconclusive. Recently there was another survey of 3123 men and women in the Netherlands. The findings do not show a relationship between coffee drinking and pancreatic cancer in men, but suggest that women who drink coffee are less likely to develop it.

Liver cancer

The relationship between coffee drinking and liver cirrhosis is often studied in North America and Europe. Liver cirrhosis is generally regarded as an early symptom of liver cancer, and the research on coffee and liver cancer can be said to be similar.

In a study of 334 subjects in Japan, normal coffee drinkers were less likely to develop liver cancer than non-coffee drinkers. And, depending on the amount of coffee you drink, the odds change positively. Compared with non-coffee drinkers, people who drank 1-2 cups a day were 50% less likely to develop liver cancer, and those who drank about 5 cups a day were 75% lower. In a Greek survey of 333 subjects, people who drank three cups of coffee a day were 30% less likely to develop liver cancer than those who did not drink coffee. In another Italian hospital study, people who drank 1-2 cups a day had a 20% lower risk of liver cancer than those who did not drink coffee, 60% lower for those who drank 3-4 cups a day, and 70% lower for those who drank more than 5 cups a day. These studies have shown the relationship between coffee and liver cancer.

How does it work?

There is no clear conclusion about how coffee oil, caffeic acid, caffeine and antioxidants in coffee play a role in fighting cancer. But most experts believe that it is a combination of antioxidants and caffeine in coffee, which has a good anti-cancer effect.

Other cancers

In 1991, IARC also speculated on the relationship between coffee and gastric cancer, but so far no definite evidence has been found. It's also about oral cancer, throat cancer, esophageal cancer, and it has nothing to do with coffee.

Speculation about coffee and breast cancer was also shown to have nothing to do with a subsequent study of 6000 subjects.

Similarly, there is no link between coffee and a series of cancers such as ovarian cancer, lung cancer, throat cancer and skin cancer.

Conclusion:

A study on bladder cancer claims to completely rule out the effects of coffee.

On the contrary, the research on bowel cancer shows the preventive and therapeutic effect of coffee on cancer.

In an earlier study of 15000 subjects, the researchers concluded that most of the conclusions showed that coffee had nothing to do with some cancers and that coffee was not a cause of cancer.
