Cancer is one of the biggest health challenges we face today. It claims millions of lives each year, and projections say the number of cases will keep growing. Although genetics and environmental factors play a part, many experts, including Dr. Saurabh Sethi, a gastroenterologist trained at Harvard and AIIMS, believe that our daily choices can greatly affect our cancer risk.
Even simple lifestyle changes can make a difference. Here’s how small adjustments can help lower your chances of developing cancer:
1. Cut Down on Processed Foods
Ultra-processed foods, like fast food and packaged snacks, often contain unhealthy ingredients. A recent study from The BMJ found that people who consume a lot of these foods have a 20–30% higher risk of cancer compared to those who eat less. Swapping these for whole foods like fruits and vegetables can help reduce your risk.
2. Boost Fiber Intake
Eating more fiber can protect you from certain cancers, especially colorectal cancer. The American Institute for Cancer Research notes that every extra 10 grams of fiber you eat daily cuts colorectal cancer risk by about 10%. Good sources include beans, oats, and berries.
3. Limit Processed Meats
Items like bacon and sausages have been classified as carcinogens by the World Health Organization. Research indicates that consuming just 50 grams a day increases colorectal cancer risk by 18%. Instead, try lean proteins like fish, chicken, or plant-based options.
4. Choose Healthier Fats
The type of fat you eat matters. Studies show that the Mediterranean diet, rich in olive oil and nuts, can lower cancer risk by up to 30%. Opting for healthy fats helps reduce inflammation and oxidative stress, both of which are linked to cancer.
5. Monitor Alcohol Consumption
Alcohol is a significant preventable risk factor. It’s linked to seven types of cancer. The National Institutes of Health reports that even one drink a day can increase breast cancer risk by 7–10%. If you drink, it’s wise to keep it minimal.
6. Maintain a Healthy Weight
Obesity increases cancer risk significantly. The CDC states that it is linked to at least 13 types of cancer and accounts for 40% of all cancer cases in the U.S. Keeping a balanced diet and staying active can help maintain a healthy weight.
7. Stay Active
Regular physical activity can lower the risk of several cancers. The National Cancer Institute found that those who exercise regularly reduce their risk by 20–40%. Aim for at least 150 minutes of moderate exercise weekly.
8. Prioritize Sleep and Manage Stress
Chronic stress and poor sleep can negatively impact our health. Dr. Sethi points out that sleeping less than six hours a night is associated with a 24% higher risk of cancer-related mortality. Creating a good sleep routine and practicing relaxation techniques can be beneficial.
In summary, while cancer remains a challenging disease, adopting simple lifestyle changes can help. Awareness and small, consistent choices can pave the way for better health and a lower cancer risk in the long run. Prevention is a journey that requires ongoing effort, but the benefits are well worth it.
