Hormone Therapy Doubles Breast Cancer Risk

Post-menopausal women who take combined hormone replacement therapy for at least five years double their risk of developing breast cancer, according to a study published Wednesday.

However, once they stop taking the combination of estrogen and progestin their risk of cancer falls by at least 28 percent within one year, said the researchers at Stanford University in California.

"This is very strong evidence that estrogen plus progestin causes breast cancer," said Marcia Stefanick, co-author of the study that appears in the February 5 edition of the New England Journal of Medicine. MORE.....

Beach Vacations May Increase Kids' Melanoma Risk

Spending vacations at the beach during childhood may increase the risk of the deadly skin cancer melanoma later in life, according to a study published Tuesday.

Researchers examined 681 white children born in 1998 who were lifetime residents of Colorado and conducted exams on the children when they were seven years old to identify nevi -- commonly known of moles -- which are a risk factor for developing melanoma. MORE.....

Brave Bad World! Cancer Survivors Declining Care Due to Costs

More than a million cancer survivors living in the United States are foregoing what they believe is necessary medical care due to the cost, and Hispanics and African-Americans are twice as likely to go without services, according to data presented at the American Association for Cancer Research conference on the Science of Health Care Disparities.

“These survivors are either going without, or significantly delaying, dental care, general medical care, mental health care or prescription drugs,” said Kathryn Weaver, Ph.D., a cancer prevention fellow at the National Cancer Institute.

Although insurance status did play a role, foregoing care due to cost still persisted among the insured. “There are significant out-of-pocket expenses, even for those with insurance,” said Weaver.

Weaver and colleagues used data from the Center for Disease Control’s National Health Interview Survey to identify 6,602 adult cancer survivors. Of these survivors, 64.3 percent were female, 4.8 percent were Hispanic, 6.4 percent were non-Hispanic black and 88.8 percent were non-Hispanic white. The survey is conducted annually and questions about 30,000 to 40,000 households.

Overall, the prevalence of foregoing medical care due to cost was 7.8 percent for general medical care, 9.9 percent for prescription medication, 11.3 percent for dental care and 2.7 percent for mental health care.

Compared to non-Hispanic whites, Hispanics were 2.14-fold more likely to forego prescription medications due to cost concerns and African-Americans were 87 percent more likely to forego prescriptions. For dental care, Hispanics were 2.31-fold more likely to go without and African-Americans were 57 percent more likely.

These differences persisted after statistical adjustments for education, health insurance coverage and non-cancer medical comorbidities.

“Efforts to expand insurance coverage might go some way toward addressing these problems, but absent that, clinicians need to be more aware that their patients are not getting these services and work to try to connect them to charity or low-cost care,” said Weaver.

Losing Weight Can Cure Obstructive Sleep Apnea

For sufferers of obstructive sleep apnea (OSA), a new study shows that losing weight is perhaps the single most effective way to reduce OSA symptoms and associated disorders, according to a new study in the American Journal of Respiratory and Critical Care Medicine, one of the American Thoracic Society’s three peer-reviewed journals.

Dark Chocolate Fights Cancer

The great news this Valentine’s Day is that in addition to being decadent and delicious, moderate amounts of dark chocolate may play a role in cancer prevention,” said Sally Scroggs, M.S., R.D., L.D., health education manager at The University of Texas M. D. Anderson Cancer Center’s Cancer Prevention Center.

Recent research indicates that dark chocolate’s chemicals, which act as antioxidants, have been shown to play a role in reducing cancer risks by helping to combat cell damage that can lead to tumor growth. These antioxidants occur naturally in the plant-based cacao bean, the base of all chocolate products. Cacao beans are, in fact, one of the most concentrated natural sources of antioxidants that exist.

Apple Juice Slows Alzheimer's Protein

Drinking apple juice helps slow the accumulation of the protein fragments that damage the brain in Alzheimer's disease, new research in mice shows.

The protein fragments, known as beta-amyloid, are the building blocks of the plaques that form in the brains of people with Alzheimer's disease.

The findings don't suggest that Alzheimer's disease can be treated by gulping gallons of apple juice, but they do point to the importance of long-term nutrition in preventing aging-related changes like those seen in Alzheimer's disease, Thomas B. Shea of the University of Massachusetts-Lowell, the co-author of the current study, said in an interview with Reuters Health.

How Much HFCS Is In Ketchup?

I was looking again at the quote from Con-Agra in regards to trace amounts of mercury found in HFCS-laced foods like ketchup, and the thing is, people don't just eat ketchup. HFCS is everywhere.

HFCS is also used as a sweetner in a vast array of common foods, from barbecue sauce to tomato soup.

The PR spokesperson said a person would have to eat 100 pounds of ketchup a day to reach the safe exposure levels. Ok then, let's reverse-engineer the quote. How much HFCS is in ketchup? Using that, plus the USDA's data that the According to the USDA, average person ate 128.3 pounds of HFCS in 2006, maybe we can figure out how much HFCS-related mercury people ingest a year, at least in the hypopthetical worse-case scenario where all HFCS has mercury.

Also, mercury builds up in the muscle of fish, does it do the same for humans?

If people are eating all this HFCS on the regular and little bits of mercury are adding up...then that's something worth looking into. It's not necessarily a crisis, but it's also not as trivial as the spokesperson tried to make it sound (imagine that).

Mercury in corn syrup? Food made with ingredient may have traces of toxic metal

A swig of soda or a bite of a candy bar might be sweet, but a new study suggests that food made with corn syrup also could be delivering tiny doses of toxic mercury.

For the first time, researchers say they have detected traces of the silvery metal in samples of high-fructose corn syrup, a widely used sweetener that has replaced sugar in many processed foods. The study was published Monday in the peer-reviewed journal Environmental Health.

Eating high-mercury fish is the chief source of exposure for most people. The new study raises concerns about a previously unknown dietary source of mercury, which has been linked to learning disabilities in children and heart disease in adults.

The source of the metal appears to be caustic soda and hydrochloric acid, which manufacturers of corn syrup use to help convert corn kernels into the food additive MORE

Peanut Recall Grows as Feds Find More Problems

WASHINGTON -- Federal officials have announced a recall of all products containing peanut paste or peanut oil produced over the past two years at a Georgia plant at the center of the current salmonella outbreak.

In a briefing Wednesday, the federal food safety officials said the plant owner — Peanut Corp. of America — had agreed to the recall.

More than 500 people have gotten sick in the salmonella outbreak, which is linked to at least eight deaths.

Wednesday's recall follow reports by federal inspectors that salmonella had been found previously at least 12 times in products made at the plant. Inspectors found that the tainted peanut products were retested, then shipped to customers.

THIS IS A BREAKING NEWS UPDATE. Check back soon for further information. AP's earlier story is below.

WASHINGTON (AP) _ Roaches, mold, and signs of a leaking roof were among numerous problems federal inspectors uncovered at a Georgia plant that kept shipping peanut butter even after it was found to contain salmonella.

A senior lawmaker on Wednesday quickly called for a criminal investigation of the plant, which has been implicated in the national salmonella outbreak.

Salmonella had been found previously at least 12 times in products made at the plant, but production lines were never cleaned up after internal tests indicated contamination, a government report said. The tainted products initially tested positive, were retested and then shipped out.

That happened as recently as September. A month later, health officials started picking up signals of the salmonella outbreak, which now has been linked to at least eight deaths.

Peanut Corp. of America's plant in Blakely, Ga., had 10 separate problem areas, Food and Drug Administration inspectors said in a report posted on the Internet.

"Here's a company that knew it had salmonella in a product and still released it," said Michael Doyle, head of the food safety center at the University of Georgia. "What they tried to do is get around it by having it tested elsewhere. But that doesn't count. The first time counts. They were selling adulterated products."

Separately, senior congressional and state officials on Wednesday called for a federal probe of possible criminal violations at the plant.

The company's actions "can only be described as reprehensible and criminal," said Rep. Rosa DeLauro, D-Conn., who oversees FDA funding. "This behavior represents the worst of our current food safety regulatory system."

In Georgia, the state's top agriculture official joined DeLauro in asking the Justice Department to determine whether the case warrants criminal prosecution.

"They tried to hide it so they could sell it," said Georgia Agriculture Commissioner Tommy Irvin. "Now they've caused a mammoth problem that could destroy their company _ and it could destroy the peanut industry."

There was no immediate response from Peanut Corp., which owns the processing plant at the center of the investigation. The company has previously said it fully cooperated with the salmonella investigation.

More than 500 people have gotten sick in the outbreak, which is continuing, and has been linked to at least eight deaths. More than 400 products containing peanut butter or peanut paste have been recalled. They range from Asian-style cooking sauces, to ice cream, to dog treats. However, major national brands of peanut butter are not affected.

Among the latest additions to the recall list were peanut butter cookies and cookie dough sold by fundraisers at 162 California schools. The products were made by Dough-To-Go Inc. and distributed throughout the state.

The peanut industry also condemned the company, portraying it as a rogue operator.

The FDA's findings "can only be seen as a clear and unconscionable action of one irresponsible manufacturer, which stands alone in an industry that strives to follow the most stringent food safety standards," Patrick Archer, president of the American Peanut Council, said in a statement.

The FDA inspection report is preliminary, and the agency said the findings do not represent a final judgment on the company's compliance with food safety laws and regulations.

But the report detailed problems which food safety experts say would be of concern.

The roaches were found in a wash room next to a packaging area. And a sink used for cleaning utensils also was used to wash out mops.

Of even greater concern, inspectors found open gaps as large as a half-inch by two-and-a-half feet at air conditioner intakes on the roof of the plant. Water stains were seen on the ceiling around the intakes and near skylights. The openings were above an area in which finished products were handled. Water leaks would be a problem because salmonella thrives in moist conditions.

A leaky roof is believed to have contributed to a 2007 salmonella outbreak in Peter Pan peanut butter.

ConAgra, the manufacturer, said the plant's roof leaked during a rainstorm, and the sprinkler system went off twice because of a problem, since repaired. The moisture from those three events mixed with dormant salmonella bacteria in the plant that the company said likely came from raw peanuts and peanut dust.

Inspectors at the Blakely plant also found that Peanut Corp. did not take proper steps to prevent finished products from being contaminated by raw peanuts. Roasting is supposed to kill the bacteria, but raw peanuts can harbor salmonella.

Three-Minute Workouts May Help Prevent Diabetes

Rigorous workouts lasting as little as three minutes may help prevent diabetes by helping control blood sugar, British researchers said on Wednesday.

The findings published in the journal BioMed Central Endocrine Disorders suggest that people unable to meet government guidelines calling for moderate to vigorous exercise several hours per week can still benefit from exercise.

"This is such a brief amount of exercise you can do it without breaking a sweat," said James Timmons, an exercise biologist at Heriot-Watt University in Edinburgh, who led the study.

"You can make just as big as an effect doing this as you can by doing hours and hours of endurance training each week."

Type 2 diabetes, which affects an estimated 246 million adults worldwide and accounts for 6 percent of all global deaths, is a condition in which the body gradually loses the ability to use insulin properly to convert food to energy.

Very strict diet and vigorous, regular and sustained exercise can reverse type 2 diabetes, but this can be difficult for many people. The condition is closely linked to inactivity.

Timmons and his team showed that just seven minutes of exercise each week helped a group of 16 men in their early twenties control their insulin.

The volunteers, who were relatively out of shape but otherwise healthy, rode an exercise bike four times daily in 30 second spurts two days a week.

After two weeks, the young men had a 23 percent improvement in how effectively their body used insulin to clear glucose, or blood sugar, from the blood stream, Timmons said.

The effect appears to last up to 10 days after the last round of exercise, he added in a telephone interview.

"The simple idea is if you are doing tense muscle contractions during sprints or exercise on a bike you really enhance insulin's ability to clear glucose out of the bloodstream," Timmons said.

The findings highlight a way for people who do not have time to work out a few hours each week as recommended to improve their health, he added.

His team did not look for other important benefits to health that come from exercise, such as lowered blood pressure or weight control, but said another study had shown similar benefits to heart function.

But Timmons said getting people to exercise even a little could translate into big savings for health systems that spend hundreds of million of dollars treating diabetes.
