The American Cancer Society has released new guidelines on diet and physical activity in cancer prevention. The document has been amended due to scientific findings of recent years. It is published in CA: A Cancer Journal for Clinicians.
The changes affected all parts of the manual. So, earlier American oncologists recommended 150 minutes of moderate physical activity or 75 minutes of intense activity per week. Now they point to the need to increase the load: up to 150-300 minutes or 75-150 minutes per week, respectively. The desired number of minutes of physical activity per week is 300.
Previously, oncologists recommended eating a healthy, predominantly plant-based diet that helps maintain a healthy weight. They advised avoiding red and processed meats, eating at least 2.5 servings of fruits or vegetables, and choosing whole grains over refined foods.
The guidelines now focus on healthy eating patterns.
“There is no single food or even food group that provides a significant reduction in cancer risk. Current scientific evidence supports a shift away from specific nutrient binding to more holistic concepts of dietary patterns. People eat foods, not nutrients, and evidence suggests that healthy eating patterns are associated with a lower risk of cancer, particularly colon and breast cancer,”said Laura Makaroff, vice president of the American Cancer Society.
Healthy patterns include foods that are nutrient-dense in amounts to maintain a healthy weight. These include many different fruits and vegetables, legumes, and whole grains. Contrary to healthy patterns, red and processed meats, sugary drinks, and ultra-processed foods.
Recommendations for alcohol have changed. It used to be that it should be limited to one standard serving a day for women and two for men. Now an indication has been added to this recommendation that it is better to completely abandon alcohol.
