（2025·江西·模拟预测）In a recent study, Keren Papier at the University of Oxford and her colleagues used 16 years of data on more than 540,000 women in the UK. The researchers found that every additional 300 milligrams of calcium (钙) per day was associated with a 17 per cent reduction in risk. “This is the most comprehensive single study ever conducted into the relationship between diet and colorectal cancer (结直肠癌), and it highlights the potential protective role of dairy products, largely due to calcium, in the development of colorectal cancer,” says Papier.
Papier’s study agrees with another recent paper that followed more than 470,000 adults for over 20 years. This similarly found an association between reduced colorectal cancer risk and higher calcium consumption.
A third study, led by Shuji Ogino in Boston, adds to the evidence, but turns the spotlight away from calcium. His team followed some 87,000 women for 40 years and 45,000 men for 30 years. At least two servings of plain yogurt a week, which contained Bifidobacterium bacteria (双歧杆菌), was linked to a 20 per cent lower rate of colorectal cancer.
When it comes to calcium pills, a 2018 report for Cancer Research suggests that they decrease the risk of colorectal cancer, but another study found that they may increase the risk of diseases that may lead to the condition. Given the widespread use of these pills, further research is needed, says Papier.The benefits of Bifidobacterium bacteria are also unknown, says Ogino.
To him, these studies illustrate the complex connection between our diet and cancer risk, with there being no shortcut to health. “If people try to go to a supermarket and buy more plain yogurt, then that’s good, but if they just stop in a day or two, there is no effect.”
People should try to follow all the cancer prevention advice such as being active and not smoking, and “not focus on the potential benefits of one food or one nutrient”, says Mathers, a health expert.
