It’s what every examination of the science of diet and health requires. For too long, authorities have demonized specific foods in an attempt to explain poor health outcomes, or anointed the latest “superfood” a panacea against disease.
That’s more or less the gist of a new article in the New York Times, “Red Meat is Not The Enemy.” The author suggests that experts historically “cherry-pick” data from individual studies to single out one nutrient or food in an attempt to determine its role in human health.
The Totality of Evidence
We agree that this can be a problem, and a misleading one. And that’s precisely why, at the American Institute for Cancer Research, when we perform our ongoing analyses of the global evidence on the connections between cancer risk and lifestyle (read: diet, weight, physical activity), we do so using systematic literature reviews and meta-analyses. (We call it the Continuous Update Project, or CUP.) Continue reading

Earlier this week, 70+ people – representing interests such as meat, dairy, public health, sugar, vegetarian, spices and sustainability – gathered at the National Institutes of Health to weigh in on what the 2015 Dietary Guidelines should say to Americans about a healthy diet.
I had the opportunity to represent AICR and speak up for guidance that will help Americans more easily make choices to lower their cancer risk. Everyone had 3 minutes to speak directly to experts from USDA and Health and Human Services who will be writing the 2015 dietary guidelines for Americans. You can watch the video here. The Dietary Guidelines (revised every 5 years) are key to how we move forward with dietary advice, and that also affects how food is produced and manufactured in the U.S. Continue reading
An analysis of worldwide research on diet, weight, physical activity and liver cancer has found strong evidence that consuming approximately three or more alcoholic drinks a day causes liver cancer. Published today, the finding provides the clearest indication so far of how many drinks actually cause liver cancer.
As a member of the independent panel of scientists that reviewed the worldwide research, this is a significant finding that I hope will help reduce the global number of cases of liver cancer. Currently, it’s the second most common cause of death from cancer worldwide, accounting for 746,000 deaths globally in 2012.
How alcohol causes liver cancer
Excessive alcohol consumption over a period of time can cause damage to the liver and lead to cirrhosis (scarring and hardening of the liver), which is known to increase the risk of this cancer. We know that 90-95% of liver cancer cases have underlying cirrhosis. Alcohol consumption is also carcinogenic to humans, has tumor-promoting effects, and is associated with increased body fat. The latter is a concern because obesity is a risk factor for accumulation of fat in the liver, which may lead to cirrhosis and also increase liver cancer risk. Continue reading
