Sarah Davidson Evanega, PhD, is fighting world hunger through biotechnology.World hunger may seem like a problem far from home. But, here's an interesting way it affects all of us: whether or not we support GMO produce. Dr. Roizen's guest this week is Sarah Davidson Evanega, PhD, the director of the Cornell Alliance for Science. One of her messages is that not all GMOs are created equal. For example, an insect-resistant eggplant in Bangladesh dramatically reduces the need for pesticides and raises the farmers' yields... so much that many are able to make big changes to their lives, like putting warm nutritious food in front of their children three times a day.

Why does heavy alcohol consumption cause "Holiday Heart Syndrome"?Between Thanksgiving, Christmas, and New Years, there are a lot of reasons to celebrate. Unfortunately, it is often a time when many people end up going to the ER due to "holiday heart syndrome." In 1987, holiday heart syndrome was described in a study of 24 patients who landed in the hospital during the holiday season due to atrial fibrillation. Atrial fibrillation, or flutter, is a common type of abnormal heartbeat and has been linked to risk of stroke. In this condition, the heart rhythm is fast and irregular. Atrial fibrillation may occur without your knowledge, causing you to not seek medical attention and thus increase your risk of death from stroke. What can cause holiday heart syndrome? Listen in as Chadd Kraus, MD, discusses holiday heart syndrome and how you can protect yourself this holiday season.

Creams and ointments that claim to address stretch marks are everywhere. What kinds are best, if any?Whether you've recently gone through a growth spurt, rapidly gained weight, or had a baby, you might have noticed a few stretch marks on your body. Stretch marks originate in the middle layer of your skin, the dermis, which supports your skin's outer surface, the epidermis. This is why they are easily spotted on your arms, legs, stomach, and back. A recent study in the British Journal of Dermatology looked at why stretch marks occur at the molecular level. Researchers studied skin samples from 27 pregnant women who suffered from recently-formed stretch marks, comparing the stretch mark skin to both nearby stretched skin on the abdomen and to less-stretched skin on the hip. Researchers found that the elastic fiber network in the dermis gets disrupted in a stretch mark. After giving birth, this network remains disrupted. Elastic fibers give skin its elasticity, or the ability to "snap back," after stretching. The skin tries to repair the disrupted elastic network, but it does not appear to be effective, which in turn promotes the lax, loose skin seen in more mature stretch marks. Is there a way that you can get rid of stretch marks? Listen in as Frank Wang, MD, shares the recent study on stretch marks and what treatments are available.

What type of exercise is best for burning fat and losing weight?Having a well-balanced metabolism is crucial in order to live a long, healthy life. Every person's metabolism is different... some may be speedy and others might be slow. But the one thing we all have in common is that as you age, your metabolism will eventually slow down. What are ways that you can build a healthy metabolism? Listen in as Francisco Torres, MD, shares how you can build a healthy metabolism.

What is a food cue, and what happens in your brain when you see one?Obesity is a very serious disease that can cause health issues like heart disease and diabetes. According to the Centers for Disease Control and Prevention, more than one-third (78.6 million) of people in the U.S. are obese. Two studies have recently given insight to your brain, how it responds to food cues, and why that matters in obesity. In the first study, researchers performed an fMRI on 12 lean and 17 obese participants, showing words representing high-energy dense foods (chicken wings, lemon cheesecake) and low-energy dense foods (red-leaf lettuce or summer squash). Researchers then asked the participants to rate how much they wanted to eat each food item. They found that the brains of the obese participants had a stronger reaction to the high-energy dense food than the lean participants. What did the other study suggest about food cues and obesity? Listen in as Susan Carnell, PhD, shares the recent findings of the two studies and how food cues relate to obesity.
