Fruit Flies Help Explain Why Diet Success Varies

A study on fruit flies has indicated that genetic interaction with diet has a greater impact on body weight than diet alone, which the researchers say can help explain different reactions to similar diets.

Published in the July issue of Genetics, the study adds weight to the theory of personalised nutrition, which suggests that the benefit of nutritional compounds varies for different people.

"This study strongly suggests that some individuals can achieve benefits from altering their dietary habits, while the same changes for others will have virtually no effect," write the researchers.

The Healing Effects of Forests

"Many people," says Dr. Eeva Karjalainen, of the Finnish Forest Research Institute, Metla, "feel relaxed and good when they are out in nature. But not many of us know that there is also scientific evidence about the healing effects of nature."

Forests - and other natural, green settings - can reduce stress, improve moods, reduce anger and aggressiveness and increase overall happiness. Forest visits may also strengthen our immune system by increasing the activity and number of natural killer cells that destroy cancer cells.

Recalled Foods Often Remain On Store Shelves

More and more, it seems that recalled foods are not making their way back to processors and current disclosure measures are not adequately alerting consumers to the dangers lurking on their grocer's shelves. In more than one case highlighted by the Chicago Tribune, consumers have fallen ill after consuming recalled food that remained far too long on store shelves, placing consumers at unnecessary risk for dangerous, often, deadly food borne pathogens.

In 2009, the U.S. Department of Agriculture (USDA) was involved in 59 recalls, said the Chicago Tribune. In all cases, the agency knew how much food was involved and how much was recovered; however, most - 56 recalls - did not tally up the complete amounts identified as problematic, said the Tribune.

Last year, a recall announced by a processor in Denver for 460,000 pounds of ground beef only turned up 119,000 pounds, leaving over 300,000 pounds of potentially dangerous meat on the market or in consumers' kitchens, said the Tribune. In that case, the pathogen was Salmonella and the beef was linked to an outbreak at the time. Later that year, another processor - this one in New York - announced a larger ground beef recall of 545,000 pounds linked to an outbreak of E. coli. According to the USDA, said the Tribune, only 795 pounds of the potentially tainted beef was ever recovered.

Chemical BPA found on cash register receipts

Laboratory tests found high levels of the estrogen-like chemical bisphenol A on 40% of cash register receipts from major U.S. businesses, the Environmental Working Group today reports.

BPA levels higher than those in canned foods, baby bottles and infant formula were detected on at least one of several receipts from Chevron, McDonalds, CVS, KFC, Whole Foods, Safeway, the U.S. Postal Service, Walmart and the U.S. House of Representatives cafeteria, according to the private Washington-based research group.

Many large manufacturers of baby bottles now sell products that are free of the chemical BPA, or bisphenol-A.

Report: Children's exposure to toxic chemicals costs Michigan billions

Lansing - Michigan could save billions annually by protecting children from exposure to environmental hazards, according to a study released today.

The report released by an Ann Arbor-based coalition of health and environmental groups examined direct and indirect costs of four childhood diseases linked to environmental toxicants: lead poisoning, asthma, pediatric cancer and neurodevelopmental disorders.

The study found treating those disorders costs Michigan an average of $5.85 billion each year. If all diseases with an environmental link were included, the number would be higher.

Can Drugs Make Americans Lose Weight? Not Likely

Image
Diet drugs have proven to be ineffective and sometimes dangerous. Yet more keep coming down the pipeline.
"I have taken this drug off and on for the past 10 years for weight loss. It works, but the results NEVER last, it makes you feel great for about six months, you lose weight, you have awesome energy to work out and then it begins to not work anymore. It's like you build up an immunity to it or something."
The comment is about phentermine (Fastin, Adipex, Ionamin), half of a new drug under consideration by the FDA, but it could apply to all the diet drugs. Thanks to human's "thrifty gene," diet drugs work until they don't work, say scientists. When the body senses it's losing its adipose stores, it actually changes the metabolic rules to retain saddlebags and love handles. Thanks for that.

So, even though two-thirds of American adults are overweight and a third obese, few drugs have been able to make a dent in our gross national product; they've proved to be ineffective and sometimes dangerous.

Fen-phen was withdrawn 13 years ago for killing at least 120 people...and it didn't even work that well, people say.

The Little Purple Pill Problem

Forbes magazine calls it "a parable of what's wrong with health care [costs]." We think that the popular drug Nexium is a scandal for a different reason - what it does to your digestion.

AstraZenica, the international pharmaceutical company worth $46.8 billion, began selling a drug called omeprazole in 1989 under the brand name Prilosec. It is a proton pump inhibitor, and it was marketed as a treatment for heartburn, peptic ulcer disease, and GERD (gastroesophageal reflux disease). Two years before the patent expired, AstraZeneca changed the formulation slightly and started selling it as a new patented drug, Nexium. What the drug company did not want was for consumers to stay with Prilosec, essentially identical to the new drug, once the old drug came off patent and the price collapsed.

This strategy worked. Nexium is easily AstraZeneca biggest seller, bringing in $5 billion so far. And part of that is its cost: $2,000 for a year's supply. While the drug company says an average consumer only pays a $30 co-pay for Nexium, a recent Forbes article points out that the rest of us are paying for it with higher health insurance rates.

Babies Shown Affection 'Cope Better' as Adults

Babies whose mothers shower them with affection are better at coping with stress when they grow up, researchers have said.

Nurturing and warmth in early life has "long-lasting positive effects on mental health well into adulthood", it was found.

Mothers were watched interacting with the babies at eight-months-old and were ranked according to number of times they were negative, warn, caressing or extravagant.

Educated people cope better with dementia

Educated people are better able to cope with the physical effects of dementia, and even one extra year of education can significantly cut the risk of developing the brain-wasting disease, scientists said on Monday.

The findings by scientists from Britain and Finland could have important implications for public health at a time when populations in many countries are rapidly aging and dementia numbers are expected to rise sharply.

The researchers found that people who go on to university or college after leaving school appear to be less affected by the brain changes, or pathology, associated with dementia than those who stop education earlier.

"More education is not associated with any differences in the damage to the brain, but people with higher education can cope with that damage better," Hanna Keage from Cambridge University, who worked on the study with an Anglo-Finnish team, said in a telephone interview.

Medical devices send 70000 American children to ER annually

More than 70,000 children and teens go to the emergency room each year for injuries and complications from medical devices, and contact lenses are the leading culprit, the first detailed national estimate suggests.

About one-fourth of the problems were things like infections and eye abrasions in contact lens wearers. These are sometimes preventable and can result from wearing contact lenses too long without cleaning them.

Other common problems found by researchers at the U.S. Food and Drug Administration include puncture wounds from hypodermic needles breaking off in the skin while injecting medicine or illegal drugs; infections in young children with ear tubes; and skin tears from pelvic devices used during gynecological exams in teen girls.
