Association Between Processed Meat Intake, Higher Colorectal Cancer Risk

 The Washington Post (5/23, Huget) “The Checkup” blog reports that, according to a study released today, “there’s convincing evidence that eating too much red meat and processed meat raises colorectal cancer risk and that consuming plenty of fiber in the form of plant-based foods reduces that risk.” The Continuous Update Project (CUP), produced by the World Cancer Research Fund and American Institute for Cancer, gathers research about “various forms of cancer, updating its database every few years.” For this report, scientists “conducted a review of published studies and ended up adding 263 new papers about colorectal cancer to the 749 that had been analyzed for the last report, issued in 2007.” The report notes that “red meat, processed meat, excess body fat, and fat carried around the waist increase risk of colorectal cancer.”

Culprit of Acid Reflux may be eating too much

In a front-page story, Sacramento Bee (5/12, 1A, Creamer) reported that acid reflux is “on the rise in America, with 25 million people experiencing daily symptoms,” up from “15 million only a decade ago,” according to the American Gastroenterological Association. Moreover, another 60 million report having heartburn once a month. “Blame stress and an aging population — and above all, experts say, blame Americans’ habit of eating too much,” because even modest weight gain can lead to acid reflux. Women with a BMI of “25 to 27, considered only slightly overweight, are more than twice as likely to develop the disease, Boston University researchers have found.”

Heavy Beer Drinkers With ADH1 Gene Variant May Have Increased Risk Of Gastric Cancer.
Medscape (4/15, Nelson) reported that a “genetic variant might predispose heavy beer drinkers to a higher risk for gastric cancer,” according to findings presented at the American Association for Cancer Research meeting. The researchers found that drinking “30 g of pure ethanol/alcohol or more a day derived from beer was associated with a 75% increased risk for gastric cancer.” Notably, when they looked at interactions between the alcohol dehydrogenase gene cluster (ADH1) “locus SNPs and baseline alcohol consumption, the authors noted a statistically significant interaction between rs1230025 and beer consumption.” The presence of “SNP rs230025 was associated with a 30% increased risk for gastric cancer.”
