Higher Inflammation in Tumors Weakens Body’s Defense
A recent study found that colorectal cancer tumors have high levels of inflammation. This inflammation makes it harder for the body to fight the disease. Researchers say the typical Western diet, which includes many ultra-processed foods, is a major cause of this inflammation.
What the Study Found
The study, published in the journal Gut, looked at 162 tumor samples from people with colorectal cancer. It found that these tumors had a “pro-inflammatory bias,” meaning they were more likely to cause inflammation. The researchers suggest using “resolution medicine” to reduce inflammation and help the body heal.
The Role of the Western Diet
The Western diet, which is high in ultra-processed foods, is strongly linked to chronic inflammation. This type of inflammation can lead to the development and growth of colorectal cancer. Ultra-processed foods, such as candy, chips, and white bread, are a big part of the problem.
Expert Opinions
Dr. Geoffrey Buckle, a gastrointestinal oncologist, said the study helps us better understand the link between inflammation and cancer. He called the research “fascinating” and said it could lead to new treatments targeting inflammation.
Do Ultra-Processed Foods Increase Cancer Risk?
In the U.S., more than 50% of adults’ daily calories come from ultra-processed foods. These foods are known to cause inflammation, which can increase the risk of diseases like cancer.
What Experts Recommend
- Limit Ultra-Processed Foods: Foods like candy, chips, and white bread can increase inflammation.
- Choose Healthier Options: Eat more whole grains, fruits, vegetables, and lean proteins.
- Focus on Anti-Inflammatory Foods: Foods like onions, garlic, and salmon can help reduce inflammation.
How Diet Affects Cancer Risk
Health experts have long warned that the Western diet can raise the risk of many cancers, including colorectal cancer. Ultra-processed foods are also linked to obesity, diabetes, heart disease, and cognitive decline.
Key Dietary Tips to Lower Cancer Risk
- Eat More Fiber: Whole grains, fruits, and vegetables are high in fiber.
- Include Antioxidants: Foods like berries, nuts, and leafy greens are rich in antioxidants.
- Avoid Processed Meats: Limit foods like bacon, sausages, and ham.
Other Factors That Increase Cancer Risk
While diet is important, other factors also play a role in colorectal cancer risk:
- Family History: Genetics can increase your risk.
- Lifestyle Choices: Smoking, drinking alcohol, and lack of exercise can raise your risk.
- Age: The risk increases as you get older.
The Importance of Early Detection
Colorectal cancer is the second leading cause of cancer-related deaths in the U.S. However, early detection through screening can save lives. The American College of Physicians recommends starting screenings at age 50.
Key Takeaways
- Chronic inflammation increases the risk of colorectal cancer and weakens the body’s ability to fight it.
- The Western diet, high in ultra-processed foods, is a major cause of inflammation.
- To reduce cancer risk, limit processed foods and eat more whole grains, fruits, and vegetables.
By making healthier food choices and focusing on anti-inflammatory foods, you can lower your risk of colorectal cancer and improve your overall health.
