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
Cancer prevention: It’s what AICR is all about. We fund research, analyze data and produce recommendations, all with the same goal in mind — saving lives.
We want to reduce the burden that cancer places on the population, both in lives lost, as well as in the billions of dollars now spent on cancer care. We want to make cancer much, much more rare.
When researchers and policy makers talk about “cancer prevention,” that’s what they mean. They’re looking at the issue from the population level, with the goal of reducing the number of cases of cancer that occur within a given group.
When we at AICR talk to the research community or policy makers, “prevention” is the word we use, as its nuanced technical meaning is generally understood.
But when we talk to individuals – when we translate the science into practical, easy-to-understand information that people can use in their daily lives, we have to be careful. Continue reading
The media is abuzz in the wake of a surprising new study published in the Journal of the National Cancer Institute linking omega-3s to a higher risk of prostate cancer. But should men give up eating their salmon?
Omega-3 polyunsaturated fatty acids are generally acclaimed for their link to reduced inflammation and overall health promotion, especially heart health. Omega-3s are found in salmon and other fatty fish as well as in supplements. Fish oil capsules containing the omega-3s EPA and DHA are among the most popular supplements.
The study measured the percent of three omega-3s most commonly found in fish and supplements – DHA, EPA and DPA – in the blood of 834 men with prostate cancer matched to 1,393 men without cancer. Men with the highest percentage of omega-3s in their blood had a 43% increased risk of prostate cancer compared to those with the lowest concentration. No increase in risk was found in the men in the two middle quartiles – in other words, those with moderate levels.
What’s a guy to do? For now, follow AICR’s evidence-based recommendations for prostate cancer. Men can include plenty of foods rich in the antioxidants lycopene (tomatoes are a great source) and selenium (found in sunflower seeds and Brazil nuts) and rest easy knowing they’re helping reduce their risk of not only cancer but other chronic Continue reading
