The American Cancer Society (ACS) has published guidelines on nutrition and physical activity to reduce cancer risk. These guidelines, developed by a national panel of experts, are based on the most current scientific evidence on diet and activity patterns related to cancer risk. The guidelines include recommendations for individual choices regarding diet and physical activity, but also emphasize the importance of community efforts to create a social environment that promotes healthy behaviors. The committee recommends one key community action to accompany the four individual recommendations to reduce cancer risk. The guidelines emphasize that weight control, dietary choices, and physical activity are the most important modifiable determinants of cancer risk for most Americans who do not use tobacco. Evidence suggests that one-third of cancer deaths in the United States can be attributed to diet and physical activity habits, including overweight and obesity, while another third is caused by exposure to tobacco products. Although genetic inheritance influences cancer risk, most of the variation in cancer risk across populations and among individuals is due to factors that are not inherited. The guidelines are consistent with guidelines from the American Heart Association and the American Diabetes Association for the prevention of coronary heart disease and diabetes, as well as for general health promotion. The guidelines recommend maintaining a healthy weight throughout life, adopting a physically active lifestyle, and consuming a healthy diet, particularly within the context of weight management. The guidelines also emphasize the importance of community efforts to create a social environment that promotes healthy food choices and physical activity. The guidelines recommend that communities take action to facilitate healthy eating and physical activity behaviors. This includes implementing health promotion programs, policies that affect community planning, transportation, school-based physical education, and food services. The guidelines also recommend that individuals limit their consumption of alcoholic beverages, as alcohol consumption is an established cause of cancers of the mouth, pharynx, larynx, esophagus, and liver. The recommended limit is two drinks per day for men and one drink per day for women. The guidelines also address specific cancers, including bladder cancer, brain tumors, breast cancer, and colorectal cancer. For breast cancer, the guidelines recommend moderate to vigorous physical activity, minimizing lifetime weight gain, and avoiding or limiting intake of alcoholic beverages. For colorectal cancer, the guidelines recommend regular physical activity, maintaining a healthy weight, and avoiding diets high in processed and/or red meat. Overall, the guidelines emphasize the importance of maintaining a healthy weight, adopting a physically active lifestyle, and consuming a healthy diet to reduce cancer risk.
