Learning God's Healthy way to a better Life!
Nutrition experts blame sugar as a major cause of the rise in obesity in the United States, noting that the rise in overweight children is especially alarming. Some scientists have zeroed in on fructose as a major cause, especially high-fructose corn syrup that is used in soft drinks and processed foods. Manufacturers have staunchly defended their product, saying it is no more a cause of obesity than other foods. New research may prove their critics were right.

Rare skin cancers of the sweat glands, hair, nails and mammary glands seem to be on the rise in the United States and scientists are trying to figure out why, according to a new study.
A joint food safety research report by the University of Arizona at Tucson and Loma Linda University says reusable grocery bags can serve as a breeding ground for dangerous food-borne bacteria and pose a serious risk to public health.
The research study -- which randomly tested reusable grocery bags carried by shoppers in the Los Angeles area, San Francisco, and Tucson -- also found consumers were almost completely unaware of the need to regularly wash their bags.
"Our findings suggest a serious threat to public health, especially from coliform bacteria including E. coli, which were detected in half the bags sampled," said Charles Gerba, Ph.D., a University of Arizona environmental microbiology professor and co-author of the study. "Furthermore, consumers are alarmingly unaware of these risks and the critical need to sanitize their bags after every use."
The bacteria levels found in reusable bags were significant enough to cause a wide range of serious health problems and even lead to death -- a particular danger for young children, who are especially vulnerable to food-borne illnesses, he said.
The study also found that awareness of potential risks was very low. A full 97 percent of those interviewed have never washed or bleached their reusable bags, said Gerba, who added that thorough washing kills nearly all bacteria that accumulate in reusable bags.
The report comes at a time when some members of the California State Legislature, through Assembly Bill 1998, are seeking to promote increased consumer use of reusable bags by banning plastic bags from California stores.
"If this is the direction California wants to go, our policymakers should be prepared to address the ramifications for public health," said co-author Ryan Sinclair, Ph.D., a professor at Loma Linda University's School of Public Health.
The report noted that "a sudden or significant increase in use of reusable bags without a major public education campaign on how to reduce cross contamination would create the risk of significant adverse public health impact."
Geographic factors also play a role, said Sinclair, who noted that contamination rates appeared to be higher in the Los Angeles area than in the two other locations -- a phenomenon likely due to that region's weather being more conducive to growth of bacteria in reusable bags.
The report -- "Assessment of the Potential for Cross Contamination of Food Products by Reusable Shopping Bags" -- offered the following policy recommendations for lawmakers, as well as tips for consumers who use reusable grocery bags:
• States should consider requiring printed instructions on reusable bags indicating that they need to cleaned or bleached between uses;
• State and local governments should invest in a public education campaign to alert the public about risk and prevention;
• When using reusable bags, consumers should be careful to separate raw foods from other food products;
• Consumers should not use reusable food bags for such other purposes as carrying books or gym clothes;
• Consumers should not store reusable bags in the trunks of their cars because the higher temperature promotes growth of bacteria.
"As scientists our focus was not on the relative merits of paper, plastic or reusable grocery bags," Gerba said. "Our intent was purely to provide relevant data to better inform consumers and lawmakers about the public health dimensions that could arise from increased use of reusable bags. With this knowledge, people will be in a better position to protect their health and that of their children."
(CNN) -- South African Dr. Sonnet Ehlers was on call one night four decades ago when a devastated rape victim walked in. Her eyes were lifeless; she was like a breathing corpse.
"She looked at me and said, 'If only I had teeth down there,'" recalled Ehlers, who was a 20-year-old medical researcher at the time. "I promised her I'd do something to help people like her one day."
Forty years later, Rape-aXe was born.
Ehlers is distributing the female condoms in the various South African cities where the World Cup soccer games are taking place.
The woman inserts the latex condom like a tampon. Jagged rows of teeth-like hooks line its inside and attach on a man's penis during penetration, Ehlers said.
Once it lodges, only a doctor can remove it -- a procedure Ehlers hopes will be done with authorities on standby to make an arrest.
"It hurts, he cannot pee and walk when it's on," she said. "If he tries to remove it, it will clasp even tighter... however, it doesn't break the skin, and there's no danger of fluid exposure."
Ehlers said she sold her house and car to launch the project, and she planned to distribute 30,000 free devices under supervision during the World Cup period.

After the trial period, they'll be available for about $2 a piece. She hopes the women will report back to her.
"The ideal situation would be for a woman to wear this when she's going out on some kind of blind date ... or to an area she's not comfortable with," she said.
The mother of two daughters said she visited prisons and talked to convicted rapists to find out whether such a device would have made them rethink their actions.
Some said it would have, Ehlers said.
Critics say the female condom is not a long-term solution and makes women vulnerable to more violence from men trapped by the device.
It's also a form of "enslavement," said Victoria Kajja, a fellow for the Centers for Disease Control and Prevention in the east African country of Uganda. "The fears surrounding the victim, the act of wearing the condom in anticipation of being assaulted all represent enslavement that no woman should be subjected to."
Kajja said the device constantly reminds women of their vulnerability.
"It not only presents the victim with a false sense of security, but psychological trauma," she added. "It also does not help with the psychological problems that manifest after assaults."
However, its one advantage is it allows justice to be served, she said.
Various rights organizations that work in South Africa declined to comment, including Human Rights Watch and Care International.
South Africa has one of the highest rape rates in the world, Human Rights Watch says on its website. A 2009 report by the nation's Medical Research Council found that 28 percent of men surveyed had raped a woman or girl, with one in 20 saying they had raped in the past year, according to Human Rights Watch.
In most African countries, rape convictions are not common. Affected women don't get immediate access to medical care, and DNA tests to provide evidence are unaffordable.
"Women and girls who experience these violations are denied justice, factors that contribute to the normalization of rape and violence in South African society," Human Rights Watch says.
Women take drastic measures to prevent rape in South Africa, Ehlers said, with some wearing extra tight biker shorts and others inserting razor blades wrapped in sponges in their private parts.
Critics have accused her of developing a medieval device to fight rape.
"Yes, my device may be a medieval, but it's for a medieval deed that has been around for decades," she said. "I believe something's got to be done ... and this will make some men rethink before they assault a woman."

People with diets high in sweets and other foods that cause rapid blood-sugar spikes may have a higher risk of developing pancreatic cancer than those who eat less of those foods, a new study suggests.
In a study of nearly 1,000 Italian adults with and without pancreatic cancer, researchers found that those whose diets were high in so-called "glycemic index" showed a greater risk of the cancer than participants whose diets were relatively low-glycemic index. MORE>>>>>>>
It is still not clear what difference milk makes to the health benefits Drinking several cups of tea or coffee a day appears to protect against heart disease, a 13-year-long study from the Netherlands has found.
It adds to a growing body of evidence suggesting health benefits from the most popular hot drinks.
Those who drank more than six cups of tea a day cut their risk of heart disease by a third, the study of 40,000 people found.
Consuming between two to four coffees a day was also linked to a reduced risk.
While the protective effect ceased with more than four cups of coffee a day, even those who drank this much were no more likely to die of any cause, including stroke and cancer, than those who abstained.
The Dutch tend to drink coffee with a small amount of milk and black tea without. There have been conflicting reports as to whether milk substantially affects the polyphenols - believed to be the most beneficial substance in tea.
Coffee has properties which could in theory simultaneously increase and reduce risk - potentially raising cholesterol while battling the inflammatory damage associated with heart disease.
But the study in the Journal of the American Heart Association finds those who drank between two and four cups a day lowered the risk of the disease by 20%.
"It's basically a good news story for those who like tea and coffee. These drinks appear to offer benefits for the heart without raising the risk of dying from anything else," said Professor Yvonne van der Schouw, the lead researcher.
Ellen Mason, Senior Cardiac Nurse at the British Heart Foundation, said: "This study adds further weight to the evidence that drinking tea and coffee in moderation is not harmful for most people, and may even lower your risk of developing, or dying, from heart disease.
"However, it's worth remembering that leading a healthy overall lifestyle is the thing that really matters when it comes to keeping your heart in top condition.
