A Daily Glass of Milk Could Reduce Colon Cancer Risk by 17%, Study Finds
Colon cancer, the third most common cancer globally, claims nearly 1 million lives annually. but a groundbreaking study published in Nature Communications suggests a simple dietary change could help combat this deadly disease: drinking a glass of milk daily. According to the research,consuming 300 mg of calcium—equivalent to half a liter of milk—can reduce the risk of colon cancer by 17%.
the study, led by senior nutritionist Dr. Keren Papier, analyzed dietary data from 540,000 women over nearly 17 years. It examined how 97 foods, drinks, and nutrients influenced colon cancer risk. “Calcium was found to have similar effects in dairy and non-dairy sources, indicating that calcium is the primary factor responsible for reducing risk,” Papier explained.
How Calcium Protects Against Colon Cancer

Calcium’s protective effects are thought to stem from its ability to bind to bile acids and free fatty acids in the intestines. This process forms a harmless “soap-like” substance, preventing these compounds from damaging the intestinal lining.”We have some ideas about why calcium has this effect,” Papier said. “It may protect against colon cancer by shielding the intestines from harmful agents.”
the study also highlighted that six other milk-related factors contributed to reducing cancer risk, further emphasizing calcium’s role. Though,not all dietary choices were beneficial. Consuming red and processed meat increased colorectal cancer risk by 8% for every additional 30 grams consumed daily. Similarly, drinking 20 grams of alcohol—roughly a large glass of red wine—raised the risk by up to 15%.
The Growing Burden of Colon Cancer
Colon cancer is a global health crisis, with nearly 2 million new cases diagnosed annually. By 2040, this number is projected to rise to 3.2 million, with deaths increasing to 1.6 million. While previous research hinted at dairy’s potential protective effects, the evidence remained inconclusive until now.
A Call for Dietary Changes
Papier emphasized the importance of a balanced diet in reducing cancer risk. “Maintaining a healthy, balanced diet, in addition to maintaining a healthy weight and stopping smoking, is one of the best ways to lower the risk of bowel cancer,” she said. “This includes reducing alcohol and red and processed meat, and also eating lots of fruit, vegetables, and whole grains.”
Key Takeaways at a Glance
| Factor | Impact on Colon Cancer Risk |
|————————–|———————————-|
| 300 mg of calcium daily | 17% reduction |

How a Daily Glass of Milk Can Reduce Colon Cancer Risk: Insights from Nutrition Expert Dr. Emily Carter
Colon cancer remains one of the deadliest cancers worldwide, with nearly 1 million lives lost annually. However, a groundbreaking study published in nature Communications reveals that a simple dietary change—such as drinking a glass of milk daily—could substantially reduce the risk of this disease. To delve deeper into the findings, we sat down with Dr. Emily Carter, a renowned nutritionist and cancer prevention expert, to discuss the study’s implications and how small dietary adjustments can lead to substantial health benefits.
The Role of Calcium in Colon Cancer Prevention
Senior Editor: Dr. Carter, the study highlights that consuming 300 mg of calcium daily—equivalent to about half a liter of milk—can reduce colon cancer risk by 17%. Can you explain how calcium provides this protective effect?
Dr. Emily Carter: Absolutely. Calcium plays a crucial role in protecting the intestinal lining.It binds to bile acids and free fatty acids in the gut, forming a harmless “soap-like” substance. This process prevents these compounds from damaging the intestinal cells, which could otherwise lead to cancerous changes. essentially,calcium acts as a shield,reducing the risk of cellular damage that can trigger cancer development.
The Impact of Red and processed Meat
Senior Editor: The study also found that red and processed meat increases colon cancer risk by 8% for every additional 30 grams consumed daily. Why is this the case,and what alternatives do you recommend?
Dr. Emily Carter: Red and processed meats contain compounds like heme iron and nitrates, which can damage the lining of the colon and promote inflammation. Over time, this damage can increase the likelihood of cancerous changes. I recommend replacing these with lean protein sources like poultry,fish,or plant-based options such as beans and lentils. These alternatives not only reduce cancer risk but also provide essential nutrients without the harmful effects.
Alcohol and Its Role in Cancer Risk
senior Editor: Alcohol consumption, especially at 20 grams per day, was linked to a 15% increase in colon cancer risk. How dose alcohol contribute to this,and what advice do you have for those who enjoy an occasional drink?
dr. Emily Carter: Alcohol metabolizes into acetaldehyde, a toxic compound that can damage DNA and proteins in the body. This damage can lead to mutations that increase cancer risk. While moderate drinking may not pose a significant threat for everyone, I advise limiting alcohol intake and opting for healthier alternatives like sparkling water with a splash of fruit juice. For those who do drink, sticking to recommended guidelines—no more than one drink per day for women and two for men—can definitely help mitigate risks.
The Importance of a Balanced diet
Senior Editor: The study emphasizes the importance of a balanced diet in reducing cancer risk. What does a cancer-preventive diet look like, and how can people incorporate these changes into their daily lives?
Dr. Emily Carter: A cancer-preventive diet is rich in fruits, vegetables, whole grains, and lean proteins while minimizing processed foods, red meat, and alcohol. For example, starting your day with a bowl of oatmeal topped with berries and a glass of milk provides calcium, fiber, and antioxidants—all of which are protective. Snacking on nuts or carrots instead of chips,and choosing grilled fish over fried options,are small but impactful changes.The key is consistency and making gradual adjustments that are lasting in the long term.
Key Takeaways for Reducing Colon Cancer Risk
Senior Editor: To summarize, what are the key dietary changes people can make to lower their risk of colon cancer?
Dr.Emily Carter: The three most vital steps are:
- Increase calcium intake: Aim for 300 mg daily through dairy or non-dairy sources like fortified plant-based milks.
- Limit red and processed meat: Replace these with lean proteins or plant-based alternatives.
- Reduce alcohol consumption: Stick to moderate drinking or explore non-alcoholic options.
Additionally, maintaining a balanced diet rich in fruits, vegetables, and whole grains is essential. These changes, combined with regular exercise and avoiding smoking, can significantly reduce your risk of colon cancer.
Final Thoughts
Senior Editor: Thank you, Dr. Carter, for sharing these valuable insights. It’s clear that small dietary changes can have a profound impact on our health. What final message would you like to leave our readers with?
Dr. Emily Carter: My message is simple: Your diet is one of the most powerful tools you have to protect your health. Start small—whether it’s adding a glass of milk to your day or swapping out processed snacks for fresh fruit. Over time, these choices add up and can make a significant difference in reducing your risk of colon cancer and other diseases. Remember, it’s never too late to make positive changes for your health.
