Coffee is a familiar drink of many people, and the majority still believes that coffee harms to their health because it contains nervous system stimulant. However, according to the research by experts from Harvard University (US), people who drink coffee with lower level of caffeine in moderation can prevent 7 dangerous types of cancers such as breast cancer, prostate and colorectal.
1. Breast cancer
According to the study, coffee reduces the estrogen receptors (ER) which are components of reproductive hormones, as well as a major cause of breast cancer. When the amount of estrogen reduces, the risk of breast cancer also decreases.
2. Skin cancer
The statistics show that women who drank more than 3 cups of coffee a day will reduce the minimum 20% risk of developing diseases related to skin cells (BCC) which is a form of skin cancer development. BCC is a common syndrome that causes cancer and drinking coffee regularly is regarded as one of measures to help prevent skin cancer effectively.
3. Liver Cancer
Italian researchers conducted a meta-analysis of 16 studies published from 1996 to January 9/2012. The result showed that drinking 3 cups of coffee per day can reduce by 50% the risk of liver cancer thanks to the preventive effects of diabetes, a risk factor for liver cancer, and the beneficial effects on liver enzymes and liver cirrhosis. Besides, a special compound in coffee which is cloromexitin acid can reduce the risk of liver cancer for people who regularly drink coffee.
4. Prostate cancer
Coffee is a drink which contains high levels of antioxidants and other substances that reduce inflammation and regulate substances – insulin; these substances can affect prostate cancer. In addition, coffee also can enhance a protein, called adiponectin, in the body which has been shown to have strong anti-cancer properties and to prevent the development of malignan cells.
5. Endometrial Cancer
Coffee is being considered as an effective substance which can fight cancers related to obesity, estrogen and insulin, and endometrial cancer is one of them. Several studies have shown that women who drink more than 4 cups of coffee a day can decrease by 25% the risk of endometrial cancer. For coffee filtered caffeine, drinking 2 cups of this type daily also helps declining by 22% the risk of infection.
6. Colorectal Cancer
According to statistics, people who do not drink coffee have 22% higher rates of colorectal cancer than those who drink 1-2 cups, and 44% compared with those who drink more than 2 cups coffee every day. Coffee can accelerate the absorption of substances in the intestines, which means that the tissues will have less time to make contact with the potential carcinogen and will significantly reduce the risk of colorectal cancer.
7. Cancer of the oral cavity
According to research by the American Cancer Association, people who drink one cup of coffee per day will be at risk of mouth and throat cancer 26% lower than those who do not drink coffee and this proportion rises to 33% for those who drink 2-3 cups of coffee daily. Research has shown that hundreds of antioxidants found naturally in coffee were effective in preventing the formation of malignant tumors in the mouth and throat.
