introduction:

Does diet affect the risk of cancer and even have an impact on cancer treatment? This issue has attracted a large number of researchers' attention. With in-depth research in the fields of microbiota, immune system, genetics, etc., scientists have gradually revealed the complex relationship between diet and cancer. At MD Anderson Cancer Center, a leading global cancer treatment center, researchers are not only committed to developing more effective treatment methods, but also hope to start with diet to provide more possibilities for cancer prevention and treatment. Here are the five important research directions of MD Anderson in the field of diet and cancer.

1. The benefits of dietary fiber in cancer treatment

A study by MD Anderson, published in the journal Science at the end of 2021, revealed the unique role of dietary fiber in cancer treatment. Research has found that melanoma patients significantly prolong their survival when receiving immunotherapy by consuming foods rich in dietary fiber. This discovery emphasizes the importance of obtaining dietary fiber from food rather than relying on nutritional supplements. The research team's findings indicate that dietary fiber not only improves intestinal health, but also helps enhance cancer treatment, opening new doors for future dietary intervention research.

2. Potential association between sugary drinks and colorectal cancer

In recent years, the incidence rate of colorectal cancer among young people has risen rapidly, which is not directly related to obesity. Based on this, Dr. Yun from MD Anderson proposed a hypothesis - whether sugary drinks are associated with a higher incidence of colon cancer. Her team used an experimental model to study the effect of high fructose corn syrup beverages on tumors, and the results showed that consuming one can of this sugary beverage per day led to an increase in tumors and a larger volume, while there was no significant change in body weight. Further research suggests that high fructose corn syrup may directly promote tumor growth. Dr. Yun's team is currently studying the effects of sugary drinks on the gut microbiota to explore whether they further promote the development of colorectal cancer.

3. The potential of leguminous foods

The BE GONE clinical trial conducted by Dr. Daniel and his team at MD Anderson found that colorectal cancer survivors who consumed one cup of white kidney beans per day experienced beneficial changes in their gut microbiota, with an increase in probiotics and a decrease in pathogenic bacteria. This discovery suggests that foods rich in natural prebiotics, such as legumes, may have potential in preventing and enhancing treatment. Researchers are conducting another study called PreFED to explore whether prebiotic foods can enhance the immune system. For example, when company employees receive flu vaccines or cancer patients receive immunotherapy, researchers observe the impact of these diets on immune responses.

4. The relationship between gut microbiota, inflammation, and immune response

The health of gut microbiota is crucial for the immune system. Dr. Robert from MD Anderson focused on the role of the intestinal mucus protective layer in preventing inflammation and supporting immune function. An experiment he conducted in 2022 showed that consuming specific foods can maintain the balance of gut microbiota, reduce inflammatory reactions, and help reduce side effects caused by certain cancer treatments. Dr. Robert's team is conducting further research to determine which foods can effectively maintain the health of the gut microbiota, in order to provide more effective dietary recommendations for cancer patients.

5. The relationship between Mediterranean diet and prostate cancer

Dr. Gregg, a urological oncologist at MD Anderson, has been studying the effects of a Mediterranean diet on prostate cancer for a long time. In an observational study, researchers found that prostate cancer patients who followed a Mediterranean diet had slower disease progression. The Mediterranean diet is rich in fruits, vegetables, beans, grains, and fish, which have good antioxidant properties. Dr. Gregg is currently conducting trials on moderate risk prostate cancer patients to observe whether a Mediterranean diet affects specific physiological indicators. In addition, researchers at MD Anderson are exploring whether the Mediterranean diet has a positive effect on melanoma patients receiving immunotherapy.

The efforts of MD Anderson Cancer Center in the field of diet and cancer research have brought new hope to cancer patients. By delving into how diet affects the prevention and treatment of cancer, they continuously drive cutting-edge research and strive to bring a healthier future to patients.
