Food industry lobbyists are exerting pressure on Congress to weaken the soon-to-be-released 2015 USDA/HHS Dietary Guidelines for Americans. If they succeed, the Guidelines will put politics before sound science, and fail to provide useable guidance for Americans that could help prevent thousands of cancers every year.
In two new appropriations bills now under consideration by Congress, language has been added that would:
- Subject the Dietary Guidelines to an arbitrary standard of evidence that doesn’t align with accepted scientific practice observed by other government entities like the National Institutes of Health, the National Academy of Sciences, the Institutes of Medicine, as well as the World Health Organization.
- Not allow the Dietary Guidelines to make recommendations on issues closely related to food and nutrition. This would mean, for example, that the clear and convincing evidence about the impact of obesity and inactivity on cancer and other chronic diseases would not be considered.
- Prevent the Dietary Guidelines from:
- proposing public health ideas to help Americans decrease our national intake of sodium, saturated fat and added sugars
- encouraging Americans to increase our physical activity, and
- providing practical guidance to families about healthy eating and living
These changes would represent a huge step backward in national health policy, and – crucially, from AICR’s perspective – mean that much of the evidence showing how people can lower their cancer risk would be effectively ignored, including the latest AICR research on the clear and convincing link between obesity and ten of the most common forms of cancer.

Nuts are in fashion, nutritionally speaking, especially for heart health. Now, a new study finds that if you eat a handful of nuts several times a week that may help lower your risk of cancer.
Study results on nut consumption and cancer prevention have been inconsistent. In this systematic review and meta-analysis published in Nutrition Reviews, the researchers evaluated 36 studies – both large population studies and clinical trials – examining the relationship between eating nuts and risk of cancer or type 2 diabetes.
By comparing people who ate the most nuts (typically at least 4-5 times per week) to those who ate the least (typically 1 time per week or less), the researchers found that the high nut eaters had 15 percent lower risk of cancer overall. In specific cancers, they found lower risk for colorectal, endometrial and pancreatic cancer. They did not find any significant difference for risk of type 2 diabetes. Continue reading
Postmenopausal women who are overweight — and especially obese — have a greater risk of developing breast cancers, finds a new study that highlights the importance of preventing weight gain, as it also raises questions about whether losing weight necessarily reduces that risk.
The study adds to a consistent body of research showing that overweight and obesity increases women’s risk of postmenopausal breast cancers. It was published yesterday in JAMA Oncology.
AICR estimates that a third of US breast cancers could be prevented if women were at a healthy weight throughout life, were active and did not drink alcohol.
In this study, as other research has seen, the heavier the women, the greater the risk. Women categorized as the most obese were at almost double the risk of the most common type of breast cancer, ER-positive, along with PR-positive tumors. These cancers are fueled by the hormones estrogen and progesterone, respectively.
The study used data from approximately 67,000 women who were all part of the Women’s Health Initiative trials. That study focused on preventing certain cancers, heart disease and osteoporosis. When the women entered the study in the mid 1990s they were 50 to 79 years old, and they were weighed. They also answered questions about their lifestyle habits, medical history and other health risk factors. After that, they were weighed annually and had regular mammograms. Continue reading
