    1. Coffee: The New Health Food?
    Plenty of health benefits are brewing in America’s beloved beverage.

    Want a drug that could lower your risk of diabetes, Parkinson’s disease, and colon cancer? That could lift your mood and treat headaches? That could lower your risk of cavities?

    If it sounds too good to be true, think again.

    Coffee, the much maligned but undoubtedly beloved beverage, just made headlines for possibly cutting the risk of the latest disease epidemic, type 2 diabetes. And the real news seems to be that the more you drink, the better.
    Reducing Disease Risk

    After analyzing data on 126,000 people for as long as 18 years, Harvard researchers calculate that compared with not partaking in America’s favorite morning drink, downing one to three cups of caffeinated coffee daily can reduce diabetes risk by single digits. But having six cups or more each day slashed men’s risk by 54% and women’s by 30% over java avoiders.

    Though the scientists give the customary "more research is needed" before they recommend you do overtime at Starbuck’s to specifically prevent diabetes, their findings are very similar to those in a less-publicized Dutch study. And perhaps more importantly, it’s the latest of hundreds of studies suggesting that coffee may be something of a health food — especially in higher amounts.

    In recent decades, some 19,000 studies have been done examining coffee’s impact on health. And for the most part, their results are as pleasing as a gulp of freshly brewed Breakfast Blend for the 108 million Americans who routinely enjoy this traditionally morning — and increasingly daylong — ritual. In practical terms, regular coffee drinkers include the majority of U.S. adults and a growing number of children.

    "Overall, the research shows that coffee is far more healthful than it is harmful," says Tomas DePaulis, PhD, research scientist at Vanderbilt University’s Institute for Coffee Studies, which conducts its own medical research and tracks coffee studies from around the world. "For most people, very little bad comes from drinking it, but a lot of good."

    Consider this: At least six studies indicate that people who drink coffee on a regular basis are up to 80% less likely to develop Parkinson’s, with three showing the more they drink, the lower the risk. Other research shows that compared to not drinking coffee, at least two cups daily can translate to a 25% reduced risk of colon cancer, an 80% drop in liver cirrhosis risk, and nearly half the risk of gallstones.

    Coffee even offsets some of the damage caused by other vices, some research indicates. "People who smoke and are heavy drinkers have less heart disease and liver damage when they regularly consume large amounts of coffee compared to those who don’t," says DePaulis.

    There’s also some evidence that coffee may help manage asthma and even control attacks when medication is unavailable, stop a headache, boost mood, and even prevent cavities.

    2. iPods can cause heart pacemakers to malfunction

    In only six years, the small, plastic device that can hold your entire record collection has revolutionised the way we listen to music, changed society and turned the ailing Apple computer company into the dominant force in the download music industry. But researchers are so concerned about new evidence of potential effects of MP3 players on heart pacemakers that a major clinical investigation is to start this month.

    The trial comes in the wake of a report earlier this year that iPods may cause pacemaker interference in up to half of patients. A study in Michigan in the US found that when an iPod was held 2 inches from a patient’s chest for five to 10 seconds it interfered with pacemakers in half the 100 patients, whose average age was 77.

    Now researchers want to test the possible dangers with other types of player and different ages of patients. "Our hypothesis is that the close approximation of portable MP3 players interfere with the appropriate sensing and recording of pacemakers," said researchers at the Children’s Hospital in Boston, Massachusetts.

    There have been concerns about the possible interference of other gadgets with pacemakers, and mobile phones are among those that have been investigated. One study showed that a phone being used at the ear was sufficiently far away to prevent a health risk, but recommended that phones not be put in shirt pockets or used near the implanted device.

    The Boston researchers point out that, unlike phones, which are usually held to the ear, portable MP3 players can be held almost anywhere, including positions close to the site of the implanted device.

    They cite the research showing that the players caused pacemaker interference in half of patients tested; with over-sensing – where the pacemaker misreads the heart’s functioning – in 20 per cent; interference in 29 per cent; and pacemaker inhibition – where the pacemaker stopped functioning properly for a time – in 1.2 per cent. In some cases, interference was detected when the players were held 18 inches from the chest.

    Those researchers said that while older people with pacemakers may not use MP3 players, they may well come close to them through contact with grandchildren. As the baby-boomer generation grows older, with many rock musicians in their 60s and 70s, the potential for older people to use MP3 players is growing.

    In the Boston trial, four different brands of MP3 players will be tested at three distances from the implanted medical device in children and adults aged four to 55 with congenital heart disease. At each distance the pacemaker will be checked for changes in sensing and pacing. The whole process takes around 10 minutes.

    3. A compound found only in hops and the main product they are used in – beer – has rapidly gained interest as a micronutrient that might help prevent many types of cancer.

    Researchers at Oregon State University first discovered the cancer-related properties of this flavonoid compound called xanthohumol about 10 years ago. A recent publication by an OSU researcher in the journal Phytochemistry outlines the range of findings made since then. And many other scientists in programs around the world are also beginning to look at the value of these hops flavonoids for everything from preventing prostate or colon cancer to hormone replacement therapy for women.

    "Xanthohumol is one of the more significant compounds for cancer chemoprevention that we have studied," said Fred Stevens, a researcher with OSU’s Linus Pauling Institute and an assistant professor of medicinal chemistry in the College of Pharmacy. "The published literature and research on its properties are just exploding at this point, and there’s a great deal of interest."

    Quite a bit is now known about the biological mechanism of action of this compound and the ways it may help prevent cancer or have other metabolic value. But even before most of those studies have been completed, efforts are under way to isolate and market it as a food supplement. A "health beer" with enhanced levels of the compound is already being developed.

    "We can’t say that drinking beer will help prevent cancer," Stevens said. "Most beer has low levels of this compound, and its absorption in the body is also limited. But if ways can be developed to significantly increase the levels of xanthohumol or use it as a nutritional supplement – that might be different. It clearly has some interesting cancer chemopreventive properties, and the only way people are getting any of it right now is through beer consumption."

    Xanthohumol was actually first discovered in 1913, isolated as a yellow substance found in hops. Researchers started studying its molecular structure in the 1950s, but for decades the only people who showed any real interest in it were brewers, who were trying to learn more about how hops help impart flavor to beer.

    In the 1990s, researchers at OSU, including Stevens and toxicologist Don Buhler, began to look at the compound from another perspective – its anti-cancer properties. It showed toxicity to human breast, colon and ovarian cancer cells, and most recently has shown some activity against prostate cancer in OSU studies.

    Xanthohumol appears to have several mechanisms of action that relate to its cancer preventive properties, scientists say. It, and other related flavonoid compounds found in hops, inhibit a family of enzymes, commonly called cytochromes P450 that can activate the cancer process. It also induces activity in a "quinone reductase" process that helps the body detoxify carcinogens. And it inhibits tumor growth at an early stage.

    In recent years, it has also been shown that some prenylflavonoids found in hops are potent phytoestrogens, and could ultimately have value in prevention or treatment of post-menopausal "hot flashes" and osteoporosis – but no proper clinical trials have been done to study this.

    Information about these compounds appears to be spreading. Hop-containing herbal preparations are already being marketed for breast enlargement in women, the OSU research report said, without waiting for tests to verify their safety or efficacy. And a supposed "health" beer is being developed in Germany with higher levels of xanthohumol.

    It’s possible, scientists say, that hops might be produced or genetically engineered to have higher levels of xanthohumol, specifically to take advantage of its anti-cancer properties. Some beers already have higher levels of these compounds than others. The lager and pilsner beers commonly sold in domestic U.S. brews have f
