When you read that you can lose weight by drinking red wine, that’s a statement that you should interpret cautiously.
The headlines on red wine and weight loss stemmed from a recent animal study investigating the effects of a purified form of the phytochemical resveratrol on preventing obesity and related complications. The authors determined that resveratrol converts a type of fat called white adipose tissue into brown fat, which is a more metabolically active (and energy-burning) type of fat that can lead to weight loss.
So why the leap to red wine in recent headlines? Resveratrol is primarily concentrated in grapes and a limited number of other foods such as peanuts and some berries. And red wine makes a catchy headline.
But although red wine is a source of resveratrol, it carries side effects with it such as being highly concentrated in calories and alcohol, all of which can promote weight gain and increase risk for disease when Continue reading
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
