| Weight-Loss Tips Differ In African-American, Mainstream Magazines
Magazines catering to African-Americans may be falling short in their efforts to educate readers about weight loss, a new University of Iowa study suggests.
African-American women's magazines are more likely to encourage fad diets and reliance on faith to lose weight, while mainstream women's magazines focus more on evidence-based diet strategies, according to the study by UI researcher Shelly Campo, published in a recent issue of the journal Health Communication.
"Three-quarters of African-American women are considered overweight or obese, compared to one-third of all U.S. women," said Campo, an assistant UI professor with appointments in community and behavioral health in the College of Public Health and communication studies in the College of Liberal Arts and Sciences.
No-Carb Diet May Curb Prostate Cancer
The researchers aren't making dietary recommendations for men. But they say the topic deserves further study. "This study showed that cutting carbohydrates may slow tumor growth, at least in mice," Duke University urologist Stephen Freedland, MD, says in a news release. "If this is ultimately confirmed in human clinical trials, it has huge implications for prostate cancer therapy through something that all of us can control -- our diets," says Freedland, who plans to start such trials next year. Freedland's team split 75 mice into three groups: Low-fat diet: 12% fat, 16% protein, 72% carbohydrate Western diet: 40% fat, 16% protein, 44% carbohydrate No-carb diet: 84% fat, 16% protein, 0% carbohydrate The no-carb diet was modeled on a special diet sometimes given to prevent seizures in children with epilepsy, Freedland's team notes.
Eat, think and be merry...Paul McKenna on how brainpower can keep you ...
And the good news is you can eat WHATEVER you want WHENEVER you want. So forget following a strict diet. Here, thanks to Paul's revised bestseller I Can Make You Thin, he tells you exactly how to get in shape for the New Year. READ: Mythbusters READ: Simple exercises READ: Losing 8st changed my life He says: "This system is so simple you will probably find it difficult to believe it will work. That's because you have been brainwashed by diets to believe that weight loss is difficult� and it's not. "The answer lies not in the diet, but in reprogramming the mind. It's called behaviour modification. "And if you follow all my instructions, I PROMISE you will begin to lose weight." LOOK into my eyes, into my eyes, not around the eyes...and get slim using your MIND! If you're desperate to lose weight after stuffing yourself silly over the Christmas period you can do it WITHOUT dieting.
Harmful pesticides found in everyday food products
Government promises to rid the nation's food supply of brain-damaging pesticides aren't doing the job, according to the results of a yearlong study that carefully monitored the diets of a group of local children. The peer-reviewed study found that the urine and saliva of children eating a variety of conventional foods from area groceries contained biological markers of organophosphates, the family of pesticides spawned by the creation of nerve gas agents in World War II. When the same children ate organic fruits, vegetables and juices, signs of pesticides were not found. "The transformation is extremely rapid," said Chensheng Lu, the principal author of the study published online in the current issue of Environmental Health Perspectives. "Once you switch from conventional food to organic, the pesticides (malathion and chlorpyrifos) that we can measure in the urine disappears.
Gene Expression Differences In Mice Fed Human And Chimp Diets
Using mice as models, researchers at the Max Planck Institute for Evolutionary Anthropology traced some of the differences between humans and chimpanzees to differences in our diet. The findings appear in the January 30 issue of PLoS ONE.
Humans consume a distinct diet compared to other apes. Not only do we consume much more meat and fat, but we also cook our food. It has been hypothesized that adopting these dietary patterns played a key role during human evolution. However, to date, the influence of diet on the physiological and genetic differences between humans and other apes has not been widely examined.
By feeding laboratory mice different human and chimp diets over a mere two week period, researchers at the Max-Planck-Institute for Evolutionary Anthropology in Leipzig, Germany, were able to reconstruct some of the physiological and genetic differences observed between humans and chimpanzees.
