Adopting Healthy Habits Can Significantly Reduce Cancer Risk, Study Finds
The World Cancer Research Fund and the American Institute for Cancer Research (WCRF/AICR) highlighted the importance of healthy lifestyle habits as an effective barrier against cancer in a 2018 study. This crucial finding emphasizes that up to 40% of cancer cases could be prevented by adopting healthier lifestyles.
The message is clear: our daily choices have a significant impact on preventing this globally feared disease.
A recent study published in the journal BMC Medicine further supports this thesis, revealing that greater adherence to the seven recommendations proposed by WCRF/AICR translates into a significantly lower risk of developing cancer. This study, focused on 94,778 adults from the UK Biobank, showed that adherence to these habits not only reduces the overall risk of cancer but also offers specific protection against particular types such as breast, colorectal, kidney, esophageal, ovarian, liver, and gallbladder cancer.
The WCRF/AICR recommendations, although simple in their statement, encapsulate a comprehensive approach to health.
Maintaining a Healthy Weight
Weight control is fundamental in cancer prevention. A healthy weight reduces the burden on the body and decreases inflammation, a factor associated with various types of cancer. Obesity, on the other hand, has been linked to a higher risk of several types of cancer, including breast, colon, and kidney. Maintaining an appropriate weight involves a combination of a balanced diet and physical activity, creating an energy balance that avoids excess body fat.
Engaging in Physical Activity
Regular exercise plays a crucial role in cancer prevention. It not only helps maintain a healthy weight but also improves hormonal regulation and immune function, both relevant factors in the fight against cancer. Physical activity doesn’t need to be strenuous; moderate activities such as brisk walking, swimming, or cycling, if done regularly, can be highly beneficial.
Consuming a Healthy Diet
A diet rich in fruits, vegetables, whole grains, and legumes, with limited consumption of saturated fats and sugars, is key in cancer prevention. These foods contain essential nutrients and antioxidants that protect cells from the damage that can trigger cancer. Additionally, a healthy diet helps avoid obesity, another significant risk factor.
Reducing Fast Food and Processed Food Consumption
These foods are often high in fats, sugars, and salt, and low in essential nutrients. Their regular consumption has been associated with an increased risk of obesity and cancer. Reducing their intake is an important step towards a healthier lifestyle and cancer prevention.
Limiting Red and Processed Meat Consumption
Red meat (such as beef, pork, and lamb) and processed meat (such as sausages and ham) have been linked to a higher risk of colorectal cancer. Limiting their consumption, according to the WCRF/AICR recommendations, can reduce this risk.
Reducing Sugary Drink Consumption
Sugary drinks contribute to obesity and overweight, increasing the risk of cancer. Moreover, high sugar intake can lead to inflammation and insulin resistance, which are related to cancer development. Opting for water or sugar-free beverages is a healthier alternative.
Limiting Alcohol Consumption
Alcohol is a known risk factor for various types of cancer, including breast, liver, mouth, throat, and esophageal cancer. Limiting its consumption, or avoiding it altogether, significantly reduces the risk of these cancers.
POTENTIAL TO REDUCE CANCER RISK
Each of these recommendations, individually, has the potential to reduce the risk of cancer and other chronic diseases. However, their true power lies in the synergy created by following all of them together.
The study also highlights that for each point increase in adherence to these recommendations (with a maximum of 7 points), the risk of cancer decreases by 7%. This dose-response relationship underscores the importance of integrating multiple healthy aspects into our daily lives to obtain maximum benefits.
However, it is crucial to understand the limitations of this study. Being observational, it does not establish a direct causal relationship between compliance with these recommendations and the reduction of cancer risk. Researchers emphasize the need for more studies to better understand the underlying mechanisms that connect these lifestyle habits with an effective decrease in cancer risk.
