New Study Links Calcium Intake to Lower Risk of Colon Cancer

A study from the University of Oxford has found that a daily dose of calcium equivalent to one glass of milk can significantly reduce the risk of developing colon cancer.

Published in the journal Nature, the research analyzed data from over half a million women, revealing that 300 mg of calcium per day may reduce the risk of colon cancer by 17%. The researchers found that calcium from sources such as dairy products, dark leafy greens, calcium-fortified bread, and even plant-based milk alternatives can offer protective effects. In contrast, processed meats and alcohol were associated with an increased risk of the disease.

Colon Cancer: A Preventable Global Health Concern

Colon cancer is currently the third most common cancer worldwide, with nearly 2 million new cases and 1 million deaths annually. Experts estimate that more than half of these cases are preventable through dietary and lifestyle changes.

The research team emphasized the importance of:

• Maintaining a healthy weight

• Increasing fiber intake

• Avoiding processed meat

• Reducing alcohol consumption

• Engaging in regular physical activity

How Calcium Helps Protect the Colon

According to lead researcher Dr. Keren Papier, calcium appears to protect the colon by binding to fatty acids and bile acids, which may otherwise promote cancerous changes in the colon lining.

Recommended calcium-rich foods include:

• Yogurt and cheese

• Dried figs

• Sardines

• Nuts

• Calcium-fortified bread and plant milks

Rising Colon Cancer Rates in Young Adults

The study also highlights increasing rates of colon cancer among younger people, reinforcing the urgent need for greater public awareness about nutrition and disease prevention.
