Researchers at Oxford University have discovered that drinking a glass of milk daily may significantly reduce the risk of colorectal cancer, a potentially fatal disease. This finding comes from a 17-year study involving over 540,000 women, with results published in the journal Nature Communications.
The Study’s Key Findings
The researchers analyzed the dietary habits of participants, focusing on 97 different foods and beverages. They found that women who drank one glass of milk daily were 17% less likely to develop colorectal cancer compared to those who didn’t include milk in their diets.
A single glass of milk contains approximately 300 mg of calcium, which has been linked to this reduced risk. Importantly, non-dairy calcium sources, such as fortified soy milk, also demonstrated similar protective effects.
How Calcium Protects Against Colorectal Cancer
Calcium binds to bile acids and free fatty acids in the colon, reducing their potential to cause cancer. This protective mechanism underscores the importance of incorporating calcium-rich foods into daily diets.
For individuals with lactose intolerance, alternative sources of calcium include:
- Fish (such as salmon or sardines)
- Legumes
- Leafy greens
- Tofu
Broader Implications
Dr. Karen Papier, the study’s lead author and a senior nutrition epidemiologist, emphasized that these findings are relevant to both men and women of all ages. Calcium is essential for everyone, from young adults to seniors, making it a critical nutrient for cancer prevention and overall health.
Tips for Reducing Colorectal Cancer Risk
In addition to consuming calcium-rich foods, researchers recommend the following lifestyle habits:
- Eat more vegetables, fruits, and legumes.
- Stay active and engage in regular exercise.
- Limit red meat consumption.
- Drink plenty of water.
- Attend regular preventive screenings.
Early Symptoms to Watch For
Detecting colorectal cancer early is crucial for effective treatment. Pay attention to these symptoms:
- Frequent constipation.
- Rectal bleeding or blood in stool.
- Persistent diarrhea.
- A history of iron-deficiency anemia.
Experts note that these signs often appear three months to two years before a formal diagnosis.
Incorporating a simple habit like drinking milk daily, alongside other healthy practices, can play a vital role in preventing colorectal cancer and promoting long-term health.
