According to the study, published in the journal Cancer Epidemiology, Biomarkers & Prevention, urine samples taken from a group of hookah smokers and non-smokers were tested to determine the amount of benzene in their body. Benzene, a chemical that has been linked to certain cancers, including leukemia, is often found in higher amounts in the bodies of those who smoke cigarettes.

Researchers said that the participants in their study who had smoked hooked had benzene byproducts in their systems at nearly 30 times the amount as in non-smokers. All participants were tested following a lounge event.

It was not clear whether a link exists between hookah use and an increased risk of leukemia.

Tim Boyle/Getty Images(NEW YORK) -- The Swiss food and beverage giant Nestlé is working on developing the lazy person's holy grail: an edible product that replaces exercise -- providing at least some of the benefits.

But it will be a while before the magical potion gets approved by the U.S. Food and Drug Administration, let alone hits the shelves of your neighborhood grocery store.

"Ideally, we'll be able to develop products that will help promote and augment the effects of exercise," said Kei Sakamoto, who heads the diabetes and circadian rhythms department at the Nestlé Institute of Health Sciences in Switzerland.

Specifically, Nestlé is working on a product that would regulate AMPK, an enzyme that scientists have dubbed the "metabolic master switch." The target customer is someone with diabetes or someone who is obese, according to the company.

Researchers at Nestlé Institute of Health Sciences and several other institutions found that a compound acts on the AMPK enzyme in mice to stop their livers from producing fat, according to a study published in July in the journal Chemistry and Biology.

But don't think you're going to drink your way to a beach body.

The product won't outright replace exercise, Sakamoto said in a statement, explaining that even run-of-the-mill exercise has such a dynamic role that Nestlé will "never be able to mimic all those effects in a single product."

Dr. Silvana Obici, an endocrinologist at the University of Cincinnati in Ohio who was not involved in the study and has no affiliation with Nestlé, said it was too early to know if the findings in mice could be replicated in humans with any success.

"Although I am very happy that new specific compounds with selective AMPK are coming to the forefront, I can say I have guarded optimism," Obici told ABC News. "It needs to be demonstrated directly and not only in trials but also in animal models of obesity and also in clinical trials."

Obici said she had guarded optimism that a drink that affects AMPK could "rev up the metabolism," but said the drink would never fully replace eating healthy and working out.

"As a doctor, I want to point out that any drug that we have at our disposal for weight reduction and obesity [does] not work unless you are implementing lifestyle changes," she said.

Minus33(NEW YORK) -- You've relied on wool socks and sweaters to stay warm during cold weather months. And now, the natural fiber is making its way from your winter wear into your gym clothes.

It might sound strange, but manufacturers are going full steam ahead with the trend.

"When you think of wool, you think of old scratchy sweaters your grandmother used to give you and that just isn't the case anymore," said Craig Sexton, marketing and assistant sales manager at Minus33, an online shop selling wool workout wear. "Merino wool is ultra-soft, natural and provides ultimate performance in almost any setting."

Typically, athletic clothing is made from man-made materials such as spandex, Lycra and polyester. But according to Sexton, wool workout wear outperforms familiar fitness fabrics in many ways.

"While synthetics are passive, Merino wool is active, reacting to changes in body temperature to keep you warm when you're cold, but releasing heat and moisture when you're hot,” he said, noting that wool performs equally well during indoor and outdoor workouts. "The best part is that wool naturally reduces chafing, odor and dries incredibly fast."

Because of its benefits, high-profile companies are incorporating Merino wool into their fitness apparel.

"Lululemon and Nike are keeping up and other brands will continue to surprise us by pushing the boundaries," said celebrity fitness expert Lacey Stone. "I've seen the trend [Merino wool] worn in my classes and I actually love it."

Other labels, including Adidas and Icebreaker, currently have wool exercise leggings and running shirts in their lines.

Sexton said he is confident that the trend will continue to grow.

"Once consumers try the product, they don't go back," he said.

iStock/Thinkstock(NEW YORK) -- Heavy drinking does not make you an alcoholic, according to a new study by the Centers for Disease Control and Prevention.

While one out of three adults drink excessively, Dr. William Brewer with the CDC says 90% of adults aren't booze-dependent because they don't have the chronic medical condition of alcohol dependency.

However, he says, "that doesn't mean that the drinking that they're doing isn't still putting themselves and others at risk of harm."

Every year, 88,000 people in the United States die from excessive drinking.

So how many glasses of wine or bottles of beer are safe to drink? For women, that is no more than one drink a day, and for men, no more than two a day.

iStock/Thinkstock(WASHINGTON) -- Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, addressed the National Press Club Friday on thet opic of Ebola and said there is no reason for widespread panic.

"Is there a large influx of Ebola people infected with people who are trying to get into the United States?" Dr. Fauci said. "The answer is no."

Regarding Thomas Eric Duncan, who died of the disease last month, Dr. Fauci said, "Yes, Duncan got in to the country but that was a very rare event because of what we know now when we do screening."

Dr. Fauci said the best way to protect the U.S. is by keeping an eye on West Africa.

"The best way to protect Americans or anyone else throughout the world is to completely suppress the epidemic in West Africa, so that there isn't any risk of it going any place else," he said.
