abnormal brain functions when it comes to looking at pictures of their own face. The study, lead by Dr. Jamie Fuesner at UCLA, used functional magnetic resonance imaging to look at the brains of BDD patients as well as healthy individuals. When viewing normal to low resolution photos of their own faces, patients with BDD displayed abnormal activation patterns in the systems of the brain that control visual processing, guide behavior, and maintain emotional flexibility. BDD patients were also found to experience greater activity in the left hemisphere of the brain, which is associated with categorization and details. Contrastingly, healthy individuals rely more on the right hemisphere, which processes information more holistically. Taken together, these results suggest that patients suffering from BDD are unable to properly process the details they observe, leading them to perceive flaw where it may not exist. Underutilization of parts of the brain that recognize the face’s overall shape and size causes BDD patients to see only pieces of their face, which are likely to look distorted in the absence of a larger context. Dr. Sabine Wilhelm, director of the Body Dysmoprhic Disorder Clinic and Research Unit at Massachusetts General Hospital, notes that anecdotal evidence from treatment has long supported what this study confirms – that the underlying defect of BDD occurs at the level of brain processing.

BDD in itself does not confer a life threatening hazard, but the likelihood of attempting suicide or being hospitalized is notably higher among BDD patients. People who suffer from BDD may also endanger their safety in situations where their attention to crucial tasks is diverted by to their fixation with appearance. Currently, treatment for BDD includes psychotherapy and SSRI and tricyclic antidepressants. If the findings of the UCLA study can be further supported, it could open up the possibility for targeted cognitive behavioral therapy as a form of treatment, which would focus on retraining patients to look at their faces in order to see the big picture.

But the U.S. Food and Drug Administration (FDA) is concerned that these candy-like products will attract children and teenagers.

| Health Junkie while attempting to quit. The 1992 national survey by psychologist Naomi Breslau shows that while 36% of those in the 15 – 24 age group and 60% of those in the 45 – 54 group used tobacco daily, 60% of the younger group and 10% of the older group were addicted. Another study found that only 3% of teens who tried to quit smoking succeeded for a one year period. Compared to quitting data for adults, this suggests that teenagers are more easily addicted to nicotine. The Journal of Family Practice, for example, warns teens that they can become “hooked from the first cigarette,” unlike adults. Thus the attraction of convenient smokeless products to teens is particularly dangerous, whether tobacco companies are purposefully targeting them or not.

Hope is still in the air, however. Last year, a historical bill known as the Family Smoking Prevention and Tobacco Control Act passed the Senate; the new law allows the FDA to regulate the manufacturing, marketing, and sale of tobacco products, just as how the FDA controls the circulation of pharmaceuticals. Currently, the FDA is requiring two makers of dissolvable tobacco products to provide data on how those under 26 view their products and information on who uses the products. Meanwhile, tobacco companies defend their products, saying that they are not meant to attract non-tobacco users and have child-proof packaging. With the new regulations, however, these candy-like products may have a shorter shelf-life than expected, as the FDA already has power to ban candy-flavored cigarettes. As smoking decreases in popularity, smokeless products are the next line to conquer in the battle against nicotine addiction. The key to winning this battle lies in today’s teens. As long as they do not get addicted to nicotine during their adolescent years, there is a good chance that soon, there will be no battle to fight. Unfortunately, the adolescent period is particularly vulnerable to addiction, both physically and mentally. This may be prevented by new and harsher regulations from the FDA in the near future. Until then, teens must learn to abstain from the seemingly harmless tablets. Just reach for a piece of real gum instead!

The good news is that tobacco use among teens has decreased. From 1996 to 2009, smoking (any use within a month) among twelfth graders decreased from 37% to 20%, stemming from a change in teens’ attitude toward tobacco use. For example, in 2002, 81% of teens surveyed said they would rather date a nonsmoker, and 64% agreed that “becoming a smoker reflects poor judgment.” The bad news is, since 2007, teens’ smoking rate has reached a plateau and remains at 20%, according to data released by the CDC. Today, teens are still at peril for becoming dependent on nicotine—through smokeless products. These data, combined with marketing that emphasizes smokeless products are not as detrimental as cigarettes, do not bode well for a future decrease in nicotine addiction rate.

Thus, many consumers looking to improve their health through food and beverage intake have turned to red wine as their alcoholic beverage of choice. However, those of you who have taken the Introduction to Wines course at Cornell, or who have experimented with a variety of wines, know that not all wines go with every type of food. More importantly, not everyone enjoys red wine. This may leave you wondering, what about the other alcoholic drinks out there? What if I want to go out for a couple of beers on a Thursday or Friday (or Sunday, Monday, Tuesday…) night? The answer: there is good news for you.

A recent study conducted by researchers at the University of California-Davis and published in the Journal of the Science of Food and Agriculture indicated that certain brews of beer are high in dietary silicon, which, according to the NIH, may be beneficial for bone health and protective against osteoporosis. The silicon concentrations of several of the beers studied are shown in the table below. The high levels of malted barley and hops found in some of the beers, such as the India Pale Ales, were responsible for the beers’ higher silicon content. In general, the lighter-colored beers, which are subject to less heat during malting, have higher silicon concentrations than darker beers, such as chocolate, roasted barley, and black malt.

In addition to these potential positive effects on bone health, the alcohol itself in beer may contribute to improving your health. While the antioxidant compounds in wine have been indicated as the beverage’s major health ben-

Thus, when you choose to enjoy a beer, you may be improving your bone strength in addition to reducing your risk of stress-induced maladies. While this news of the potential health benefits of beer consumption may be encouraging, there are a few caveats. First, it is important to remember that these benefits are derived from consuming beer in moderation. Excess beer intake may result in excess caloric intake, in addition to poor liver health. Second, bone health can be improved by consuming foods and beverages other than beer. Silicon is found in relatively high amounts in foods that contain the husk of whole grains, such as barley, wheat bran, oats, and rice bran. These whole grains are found in foods such as granola cereal, high fiber wheat bran cereal, oat bran, porridge oats, and dried dates. Furthermore, the calcium and vitamin D found in milk are known to improve bone mineral density. Thus, a well-balanced, varied diet may include all of the silicon, calcium, and vitamin D that you need for optimal bone health.

Several Democratic lawmakers and liberal advocates say that the remedy to this ongoing problem is to compel the Democratic population in both the House and the Senate to vote for the Health Care overhaul bill that the Senate passed on Christmas Eve. The concern with this solution is that many house members do not like the fact that the bill includes a tax on high-cost health insurance plans.
