Another Plastic Health Risk - Erectile Dysfunction

FitSugar — Tue, 17 Nov 2009 18:13:34 -0800

While there have been previous studies, linking bisphenol A (BPA), found in hard plastics, to health problems, including precancerous tumors, prostate cancer, and brain damage, a new study, conducted in China, substantiates its claims with results in humans. In one of the first studies of its kind to be conducted on humans, researchers are finding that much of what they've previously seen in animal studies holds true - men exposed to significant amounts of BPA are at greater risk of sexual health problems.

The study compared the levels of sexual dysfunction in two groups of male factory workers - one group, which was exposed to high levels of BPA, while the other was not. The overall findings of the research reveal that when BPA enters the body, it may mimic estrogen, and block male sex hormones from functioning. In the males who were exposed to high levels of BPA, researchers observed that the risk of erectile dysfunction was four times that of a man not exposed to the chemicals.

According Dr. Rebecca Sokol, the director of the andrology program at the University of Southern California's Keck School of Medicine, and specialist in the effects of toxins on the reproductive system, these are some "compelling results." She notes that, "It's not cause and effect, but when you have the kind of ambient air quality assessment that they made, it comes pretty close to cause and effect."

E-Patients Explore Online Communities

FitSugar — Tue, 17 Nov 2009 03:00:32 -0800

Researching your health problems online can be a great way to educate yourself - or scare yourself silly. A whopping 97 percent of Fit readers 'fess up to doing some Internet sleuthing before heading to the doc. There's even a word for us: e-patients.

According to a new study by the Pew Internet and American Life Project, about 20 percent of e-patients use social-networking and similar sites to chat with medical experts and other patients.

Of course, we're big fans of community around here as a place to share information and links and get a conversation going. To find out more about the online health community revolution, read more.

Says Pew's Susannah Fox:

"They are posting their first-person accounts of treatments and side effects from medications. They are recording and posting those podcasts. They're tagging content. They are part of the conversation. And that, I think, is an indicator of where we could be going in terms of the future of participatory medicine."

In addition to connecting with fellow patients suffering from the same ailments, users are posting their health records online so they can track their test results, blood pressure, and other vital stats. All they're doing all this despite the fact that doctors are behind the times, with only about 17 percent reporting the use of online medical records.

When you're suffering from an ailment, it can be very reassuring to hear from other patients who've gone through the same thing; often, it calms me down and makes me realize I'm not alone. But do you see any danger in patients posting about their medical problems in online communities?

Who Knew? Texting's Tied to Neck Pain

FitSugar — Fri, 13 Nov 2009 03:00:20 -0800

Turns out excessive texting can get you more than a hefty phone bill. Though it's the preferred choice of easy communication for young adults and teens, a new study reveals that texting can actually increase upper body pain in the neck and shoulders.

Though this is only a preliminary study, the research shows that the same neck and shoulder discomfort seen in working adults is now being seen in college students between the ages of 18 and 21, specifically males. Judith Gold, an assistant professor of epidemiology at Temple University’s College of Health Professions and Social Work, says of the study's findings, "What we’ve seen so far is very similar to what we see with office workers who’ve spent most of their time at a computer. The way the body is positioned for texting - stationary shoulders and back with rapidly moving fingers - is similar to the position for typing on a computer."

Interestingly enough, the study didn't point to any texting-caused discomfort in the arms and wrists, but stay tuned - Gold says the research is just underway and further studies are likely to deliver more conclusive answers on whether this is all text-attributable neck tension.

Best Buy No Longer Just Selling Couch-Potato Electronics

FitSugar — Thu, 12 Nov 2009 15:00:21 -0800

When I hear my husband is headed to Best Buy, I get a bit nervous. My fears my be slightly allayed by the fact that select outlets of this electronics mecca will be selling my favorite fitness accessory that features a computer chip: heart rate monitors. Forty stores in Arizona, Colorado, Iowa, Maryland, Massachusetts, Nebraska, New Mexico, and Texas will be selling HRMs as well as pedometers and gear for swimming, yoga, and Pilates enthusiasts. Many locations will also have cardio machines like ellipticals, treadmills, and stationary bikes for shoppers to test drive. My guess is that the store is also hoping you will think that you need a flat-screen TV for your new home gym, but I still take this as a positive sign for incorporating fitness into daily life.

High-Fructose Corn Syrup Linked to High Blood Pressure

FitSugar — Thu, 12 Nov 2009 03:00:00 -0800

No matter how much the Corn Refiners Association tries to convince us that high-fructose corn syrup is healthy, I'm not buying it. Now I have another reason to avoid it: new findings have linked high-fructose corn syrup to high blood pressure, aka hypertension.

In the past 20 years alone, Americans have increased fructose intake by 30 percent, and that increase tracks closely to the rise in obesity. But it may also be contributing to high blood pressure. A team of doctors at the University of Colorado Denver studied more than 4,500 adults with no prior history of hypertension and tracked their fructose intake with a dietary survey. The results are pretty persuasive, so read all about it.

Another Reason to Eat Carbs: Boost Your Mood

FitSugar — Wed, 11 Nov 2009 03:00:56 -0800

The majority of Fit readers call themselves carb queens, and Winter can make those carbohydrate cravings even more intense. But have no fear: scientists are finding even more reasons not to avoid this essential food group.

A recent study of more than 100 obese and overweight adults in Australia found that dieting put people in a better mood; a drop in pounds led to increased satisfaction. But for people on low-carb diets, the mood boost didn't last.

The study group was split, with half the subjects on a lowfat diet and the other half low-carbing it. Interestingly, folks in both groups lost the same amount of weight on average, about 30 pounds. But after a year, the low-carb dieters also lost the positive mood effects, while the low-fat dieters did not. Here's more from the study.

With Teen Obesity, Inactivity Is Only Part of the Problem

FitSugar — Tue, 10 Nov 2009 14:32:46 -0800

I panic every time I see another "exercise doesn't work!" story - until I read between the lines and learn once again that exercise is a good thing. On the heels of its conversation-starting cover story on the exercise "myth," Time is tackling a new study of teen obesity that claims inactivity is only partly to blame for heavier kids.

Obesity rates in teenagers have triple between 1976 and 2004, with lack of exercise the suspected culprit. But a new report published in Obesity Reviews says that physical activity levels among teens have actually stayed fairly steady. So does that mean that exercise doesn't matter? Hardly, so read more.

Unfortunately, this latest study only looked at activity levels, not eating habits, and the participants were self-reporting on their own habits, which can lead to unreliable data. These figures merely suggest that the increase in teen obesity can't be explained away by teens' lack of exercise, according to Dr. Youfa Wang, the lead author of the study. Here's more:

So does this mean that exercise isn't important in controlling weight? As tempting as that conclusion might be, Wang and other health experts say that's not exactly what the new data show. . . . While exercise may not contribute directly to weight loss, it is critical for maintaining a healthy weight, since it helps calibrate the balance between energy taken in and energy burned off. "The data is too gross, and too general, to assume that [exercise doesn't count]," warns Dr. Janet Walberg Rankin, a professor in the department of human nutrition, foods, and exercise at Virginia Tech. "We need to have a dual approach to weight involving both activity and diet. I would hate for people to take away from this study that activity has nothing to do with weight."

Phew! Thanks, doc. I also hope that's not what people take away from this study. In fact, to me, it says the opposite. If teen obesity is going up because teens have increased their calorie intake without increasing their activity levels, then that seems to say pretty clearly that exercise does make a difference. Do you agree?

It's True! We Really Do Crave Fatty Foods When We're Stressed

FitSugar — Tue, 10 Nov 2009 03:00:42 -0800

If your chocolate cravings are any indication, you may have already suspected that high-fat foods are a woman's go-to snack when stressed. Now there's evidence to confirm your suspicions - UCSF recently conducted a study to examine the relationship between eating habits and chronic stress.

Researchers surveyed 600 overweight or obese women regarding their diet and stress. Issues classified as chronic stressors included job dissatisfaction, financial worries (like inability to pay rent or mortgage), or dealing with an ailing loved one. The women dealing with these taxing personal issues reported a higher likelihood of being unable to control what they ate, and a tendency to eat more fattening foods. Chronically stressed women were also more likely to force themselves to keep a regimented, strict diet to control weight gain, even skipping meals. The downside is that it's hard to keep up a regimented program, and being stressed means a plan like this is bound to backfire - ultimately there's a breaking point, and we're more likely to overeat.

While this study may not offer any groundbreaking info, it does serve as a healthy reminder: Be conscious of when you're actually hungry, and remember, there is such a thing as emotional eating. Be more mindful of your mental health and how it affects your food choices, and make healthy eating a priority.

Morning Exercisers Burn More Calories

FitSugar — Thu, 05 Nov 2009 13:00:55 -0800

Whether you're a fan of daylight saving or not most of us have to live with that fact that it gets darker much earlier. That means if you used to sweat it out after work, you may have to rearrange your schedule and make time for it before your nine-to-fiver. Not too motivated to set your alarm early? Here's something that might perk you out of bed and help you deal with the new studies on exercise and weight loss. Researchers at Bangor University in the United Kingdom discovered that a.m. exercisers work out harder than those who exercise at other times during the day. That translates to more calories burned. Why is that? People tend to be more energetic and alert in the morning, and may also feel less rushed than those who squeeze gym time into the middle of their busy schedules.

That's not to say that morning exercise trumps exercise at other times of the day. If you're not a morning person or can't fit it in at that time, don't force it. The most important thing is to fit exercise in, period, whenever you can.

Tell me, have you switched to morning workouts because of daylight saving time?

Diet Soda May Be Damaging Your Kidneys

FitSugar — Tue, 03 Nov 2009 10:00:44 -0800

A while back we learned that soda, both diet and regular, was bad for the heart, and now it looks like more organs are at risk: the kidneys. This time it's diet sodas, or more specifically, the artificial sweeteners, that seem to be the culprit. A study published recently of over 3,500 women found that those who drank two or more diet sodas daily had decreased liver function by about 30 percent. This percentage is significant, for at the beginning of the six-year study, the participants all had normal kidney function. Drinking two servings or fewer of diet soda daily did not decrease kidney function, which does naturally slow down with age. It looks like that diet soda, along with most other things, should be enjoyed in moderation.
