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.

Half of cancers – one of every two cases – can be prevented and so often it’s about applying what we already know. That was the simple but powerful message at the first Cancer Prevention Summit held by the New York State Department I attended last week. The overarching message of the Summit was simple: 50% of cancers can be prevented and in New York State, where approximately 35,000 people die from cancer each year, primary cancer prevention is an urgent public health priority.
Experts spoke about vaccinating against HPV and preventing tobacco use, two major causes of cancers. What fewer people may know is there are concrete things that we can do to reduce our risk. Maintaining a healthy weight, engaging in regular physical activity, and eating well can prevent approximately one of three of the most common cancers.
Summit highlights included:
Shift the discussion to the notion that “cancer is preventable.” Begin to focus effort and awareness on risk reduction through modifiable lifestyle habits. This includes eating a predominantly plant-based diet, achieving and maintaining a healthy weight, exercising regularly, using sunscreen, participating in cancer screening, and avoiding tobacco use and heavy alcohol.

Have you ever resolved to eat healthier, only to be tempted by fast food options everywhere you look? Do you think you would exercise more if only you didn’t have to spend so much time in your car?
Many in the public health community think that factors like these play a big role in what we eat, how much we move, and what we weigh. And many communities have tried to change these factors through so-called “environmental interventions.”
Researchers from Drexel University set out to test whether these environmental interventions work in a study recently published in the journal Obesity Reviews. They conducted a systematic review looking at the impact of various environmental interventions on diet, physical activity, and obesity. Their review included 37 natural and “quasi-“ experiments. About half of these studies focused on diet.
They found that studies involving mandatory changes to the food environment—such as laws banning trans fat in restaurants or requiring healthier foods to be offered in schools—were effective in their intended outcomes. Policies that make it easier for low-income people to use their benefits to buy fruits and vegetables were also effective. Continue reading
