Like Throwing Away $13 Billion

1 Study Says Weight Loss Supplements Don’t Work

Diet aids don’t work to facilitate weight loss beyond the placebo effect, finds a new Swedish study. Researchers tested nine popular supplements ranging from appetite suppressants to metabolism boosters to carb and fat blockers. Unlike prescription medications, “effectiveness does not have to be proven for these to be sold,” said study leader Dr Thomas Ellrott, U of Gottingen Medical School, whose tests included guarana seed powder, fiber pills and L-Carnitine. In a blind test,189 obese participants were given either the weight loss supplements or a placebo for eight weeks. No statistical weight loss difference was found between those taking the supplements or those who received the placebos. Weight loss supplements account for more than $13 billion in annual sales worldwide.

Reasons Are Unknown

2 Childhood Obesity on the Decline

Thousands of sixth graders enrolled in a school health program weighed less in eighth grade than their non-participating counterparts, finds the National Institutes of Health. Researchers followed more than 4.500 students and noticed an overall decline in the rates of obesity in both groups suggesting that childhood obesity may be on the wane. At the start of the study, 30 percent of kids were overweight. Students enrolled in the program practiced healthy eating and increased their physical activity. After two years, the percentage of overweight kids dropped to 24.6 percent for the participation group and 26.6 for the control group. “Something is going on in the environment that is leading kids to become less overweight or obese,” said Dr. Gary D. Foster, Temple U, Philadelphia.

CDC Announces New Research

3 Salsa and Guacamole Sources of Foodborne Illness

Between 1998 and 2008, almost one out of every 25 foodborne outbreaks with identified food sources associated with restaurants may be traced to contaminated salsa or guacamole. That's more than double the rate in the previous decade, says the Centers for Disease Control and Prevention (CDC). Today at the International Conference on Emerging Infectious Diseases, the CDC announced the details of their new research into the role of salsa and guacamole in illness outbreaks. Researchers say that the foods, often made in large batches, contain diced raw produce like hot peppers, tomatoes and cilantro, all of which have been implicated in outbreaks. They urge restaurants and anyone making salsa and guacamole to prepare carefully and make sure they refrigerate the foods to help prevent illness.

Lose Weight and Cool Down

4 Weight Loss Alleviates Hot Flashes

Bothersome hot flashes during menopause can be reduced by losing weight, find researchers at the University of California, San Francisco. Specifically, overweight and obese women in the study who participated in a weight-loss program were twice as likely to experience an improvement in hot flash symptoms. According to CNN, for each 11 pounds the women lost, they were about one-third more likely to experience a decrease in the frequency or severity of hot flashes, compared to women who didn't lose weight. Women in the study who lost weight participated in a program that included 40 minutes a day of moderate exercise, weekly counseling sessions and a 1,500 calorie per day diet. Study findings were published in the Archives of Internal Medicine.

Sexual Problem Linked with Heart

5 ED, Depression Increase Cardiovascular Risk

Erectile dysfunction (ED) and depressive mood are often linked, plus they're associated with elevated risk of cardiovascular disease and death, say researchers at the University of Florence. The new study, published in the Journal of Sexual Medicine, found that men with ED and depression had increased cardiovascular problems independent of other known risk factors. "What is important about this study is the broader concept of the sexual medicine problem no longer being just about a man's performance in the bedroom, but about his psychological mood and his cardiovascular health," states Irwin Goldstein, Editor-in-Chief of the Journal of Sexual Medicine. Researchers think that recognizing depressive symptoms in men with ED is important for preventing cardiovascular diseases.

Taste Buds of Fat Men Vs. Lean

6 Obese Men Less Sensitive to Taste of Fat

New research revealed differences in how obese and lean men react to the taste of fat. The research, from the University of Adelaide in Australia, found that obese men don't taste fat as well as lean men. Researchers also found that in obese men, fat is less effective at stimulating appetite-suppressing gut hormones. "At this point it is not possible to tell whether reduced responsiveness to the taste of fat or reduced gut hormone release causes over-consumption of fat, or whether eating a high-fat diet impairs taste and hormonal responses to fat," says Christine Feinle-Bisset, a professor at the University of Adelaide. Her team is performing further studies. The current research was presented at the Annual Meeting of the Society for the Study of Ingestive Behavior (SSIB).

Natural Source of Melatonin

7 Tart Cherry Juice May Be Natural Cure for Insomnia

According to a new study published in the Journal of Medicinal Food, tart cherry juice could help reduce the severity of insomnia and time spent awake after going to sleep. The small study of 15 older adults found that those who drank 8 ounces of a tart cherry juice beverage called CheriBundi twice a day (morning and evening) for two weeks reported less sleeplessness and saved about 17 minutes of wake time after going to bed. The researchers suspect that the high content of melatonin in the tart cherries help to moderate the body’s sleep-wake cycle. Sleep issues plague more than 40 million adults in the United States, according to statistics by the National Institutes of Health. Cherries are also rich in anthocyanins that provide health benefits such as reduced inflammation.

Cover Your Cough

8 One in Four Do Not Cover Mouth When Sneezing

Approximately one out of every four people observed in a public setting failed to cover their mouth when they coughed or sneezed, according to new research from Otago University Wellington, presented at the International Conference on Emerging Infectious Diseases. The majority of those who did cover used the improper technique of using their bare hands. One of the simplest actions to prevent the spread of infection is to cover the mouth during a sneeze or cough, preferably with a tissue, handkerchief, or into the elbow of a shirt sleeve. The observers also found a drop in other hygiene behaviors since last winter’s H1N1 influenza pandemic, including a reduction in public use of a hand sanitizer station near the entrance to the hospital where the study took place.
