A paper in Food Chemistry suggesting cranberry extract has healing properties was retracted after some of the authors complained they had no idea the paper was being published.
Here’s the notice for “Phenolic composition, antioxidant properties, and endothelial cell function of red and white cranberry fruits:” Continue reading Paper on cranberries’ health benefits retracted after researcher forges authors’ names
A paper estimating the effects of limiting fast food meals with toys to under 550 calories has been retracted after concerns arose regarding the scientists’ use of an outdated model for estimating weight changes in kids.
The paper estimated that kids who eat fast food twice a week would avoid gaining two pounds a year if calorie limits are imposed on meals with toys. However, everyone we spoke to, and the notice, indicated that their estimate was inaccurate.
Here’s the notice for “Modeling Potential Effects of Reduced Calories in Kids’ Meals with Toy Giveaways”:

After our post yesterday on a fishy retraction from author Brian Peskin, a reader who alerted the journal to problems got in touch to give us the lowdown.
Ian Garber is in the last year of medical residency at the University of British Columbia. Here’s the story he told us via email: Continue reading “Know how to recognize pseudoscience:” Reader reveals how fish oil paper came to be retracted
The Journal of Lipids has retracted an aggressively negative review article called “Why Fish Oil Fails,” written by one Brian S. Peskin, whose bogus health claims have landed him in plenty of hot water in the past.

On Monday, we were first to report that a study of green coffee bean extract for weight loss touted on the Dr. Oz Show had been retracted.
That story has been widely picked up by the media, including The Washington Post, which yesterday reported that the show had posted a statement about the development: Continue reading Dr. Oz: Following green coffee bean diet retraction, site scrubbed, “further study is needed”
Two authors of a 2012 paper sponsored by a company that made grand claims about green coffee bean extract’s abilities to help people lose weight have retracted it. The study was cited by The Dr. Oz Show, and last month it cost the company a $3.5 million settlement with the Feds.
Here’s the notice for “Randomized, double-blind, placebo-controlled, linear dose, crossover study to evaluate the efficacy and safety of a green coffee bean extract in overweight subjects,” a paper originally published in Diabetes, Metabolic Syndrome and Obesity: Targets and Therapy: Continue reading Authors retract green coffee bean diet paper touted by Dr. Oz
Guangwen Tang, a rice researcher at Tufts University, landed in hot water in 2012 after her team was accused of feeding Chinese children genetically modified Golden Rice without having obtained informed consent from the parents.
Now, she’s suing both Tufts and the American Journal of Clinical Nutrition, which reportedly is retracting a paper, “ß-carotene in Golden Rice is as good as p-carotene in oil at providing vitamin A to children,” based on the federally funded research, claiming that the retraction would constitute defamation. (That retraction hasn’t happened yet.)
This isn’t the first time we’ve heard the retraction = defamation line. Readers might remember Ariel Fernandez, who threatened to sue us for writing about an expression of concern. Maybe a course on the Streisand Effect should be mandatory for PhD students?

The British Journal of Nutrition has retracted a 2013 paper by a group of researchers from Taiwan after learning that the authors had studied the wrong strain of microbe.
The article was titled “Oral Lactobacillus reuteri GMN-32 treatment reduces blood glucose concentrations and promotes cardiac function in rats with streptozotocin-induced diabetes mellitus.”
According to the abstract: Continue reading Lactobacillus intolerance: Bacterium mixup forces retraction
It’s not unusual for us to hear allegations that journals have caved to corporate demands that they retract papers. And companies have certainly objected to the publication of results that painted their products in an unflattering light.

The journal Appetite has retracted a recent paper that purported to show that children whose parents kept a tight fist on the grub were less likely to become obese than those whose parents were more laissez-faire with the feed bag.
The article, “Relation of parenting styles, feeding styles and feeding practices to child overweight and obesity. Direct and moderated effects,” appeared last year. The senior author was Laura Hubbs-Tait, of Oklahoma State University. Continue reading Spreadsheet error forces loss of Appetite paper on obesity and parenting styles
