The Truth About Common Nutrition Myths

If the last time you ate fried anything was at the state fair three years ago, we have news for you. No, funnel cake hasn't become the diet food du jour. But fried foods -- as well as burgers and beer -- can have a place in a healthy diet. Surprised? No wonder. "With all the misinformation and exaggerated health headlines out there, it's easy to get fooled," says Robert J. Davis, PhD, an adjunct professor at Emory University's Rollins School of Public Health and the author of Coffee Is Good for You. To help you figure out which truths to swallow, we asked the experts to debunk the top 10 food myths. Read on to find out what's standing between you and better health, not to mention that basket of chicken fingers.

Myth: Red wine is tops for your ticker. The real deal: When it comes to heart health, red wine gets all the glory. But that glass of Syrah may not be so superior: University of Texas researchers found that although moderate drinkers lived longer than those who abstained, wine drinkers weren't better off than those who preferred beer or liquor.
"Reports of red wine's antioxidant powers were probably overblown," says Arthur Klatsky, MD, the senior cardiology consultant for Kaiser Permanente, a nonprofit health plan based in Oakland, California. The alcohol itself is what boosts levels of HDL, or "good," cholesterol. "The molecules act like Drano in your blood vessels, sweeping away plaque," Dr. Klatsky says. "This lowers your risk of developing blood clots, which can lead to strokes and heart attacks." Whether you prefer Pinot or pilsner, raise a glass to your health -- and then switch to water. Tossing back more than two drinks a day does your heart more harm than good, Dr. Klatsky says.
Myth: Organic produce packs more nutrients than the conventional kind. The real deal: Although buying organic fruits and veggies helps protect the environment, research published in theAmerican Journal of Clinical Nutrition found that they have no nutritional advantage over their conventionally grown counterparts. And while the latter contain more chemical residue, no studies have definitively proven that the amount of chemicals we ingest causes any harm: Much of the research linking pesticides with disease was done on farmers who had been exposed to huge quantities, Davis says. Still prefer organic? Spend the extra money on produce that has a peel you eat, such as apples and peaches.
Myth: A grilled-chicken sandwich beats a burger. The real deal: This seemingly healthy favorite not only contains more calories -- roughly 350 versus 250 -- than a plain hamburger, but it can also be a sodium bomb. "Many restaurants use chicken that has been injected with a saltwater solution to keep it moist," says Stephen Sinatra, MD, a cardiologist in Saint Petersburg, Florida, and a coauthor of The Fast Food Diet. Even a no-frills chicken sandwich with just lettuce, tomato, and mayo can pack more than 1,300 milligrams of sodium. That's more than double the amount in a burger and more than half of your daily quota.
Worried about a burger's toll on your heart? Don't be. A recent study in the American Journal of Clinical Nutrition found that people who ate about five ounces of lean beef daily as part of a healthy diet lowered their cholesterol level by the same amount as those who ate less beef.
Myth: Wheat is wicked. The real deal: With celebrities such as Gwyneth Paltrow and Lady Gaga praising gluten-free diets, it comes as no surprise that sales of products made without gluten -- a protein found in wheat, barley, and rye -- have nearly tripled since 2006. But unless you're one of the estimated 7 percent of people in the United States with celiac disease or a gluten sensitivity, there's no need to avoid the stuff.
"Wheat is packed with important nutrients, including folate," says Jessica Crandall, RD, a dietitian in Denver and a spokeswoman for the Academy of Nutrition and Dietetics. Few gluten-free breads, cereals, or pastas, meanwhile, are a good source of folate, a B vitamin. "Shun whole grains completely and you may even wind up gaining weight," says Bonnie Taub-Dix, RD, the author ofRead It Before You Eat It. That's because they boost the level of the feel-good chemical serotonin in your brain, so if you skip them, chances are you'll feel unsatisfied and wind up snacking unnecessarily.
Myth: Sprinkling on less salt keeps sodium in check. The real deal: Nine in 10 Americans consume more than 2,300 milligrams of sodium, the recommended daily threshold, according to the Centers for Disease Control and Prevention. Laying off the shaker can help a little, but 90 percent of the sodium in our diets comes from processed and restaurant foods. "Manufacturers use it as a preservative, so it's found in items that don't even taste salty, like bread," says CDC epidemiologist Elena Kuklina, MD, PhD. The first step toward cutting back: reading labels. Go for breads with fewer than 100 milligrams a slice and soups with no more than 140 milligrams per serving.
Myth: Raw veggies rule. The real deal: There's no need to crunch through another plate of crudités in the name of nutrition. "Besides making vegetables more palatable, cooking can also increase their nutritional value," says Tammy Roberts, RD, a nutrition and health-education specialist at the University of Missouri Extension. In fact, Cornell University scientists found that stewing tomatoes for a half hour increased their cancer-fighting lycopene content by 35 percent. Cooking also unlocks another nutrient, beta-carotene, in corn and carrots. "Heat breaks down the fibrous cell walls, releasing more of these antioxidants," Roberts explains.
On the other hand, water-soluble vitamins, including vitamin C, are usually destroyed by heat. "To cover all your bases, eat a variety of vegetables," Roberts says. If you dig into a salad at lunch, consider serving roasted broccoli or carrots as a side dish at dinner.
Myth: Brown eggs are better than white. The real deal: Despite their higher price tag (they can cost up to 20 percent more), brown eggs aren't all they're cracked up to be. "Although they look more wholesome, they have the same nutritional breakdown as the white kind," Crandall says. "They simply come from a different breed of hen."
Instead, put your extra dollars toward omega-3-enriched eggs, which can deliver more than 600 milligrams of these heart-healthy fats, compared with the 30 milligrams provided by the regular kind. Researchers found that people who ate fortified eggs daily experienced a 32 percent decrease in their triglyceride level. For the biggest benefit, look for brands that contain both EPA and DHA, two easy-to-absorb omega-3s.
Myth: High-fructose corn syrup is worse for you than sugar. The real deal: It's been blamed for America's obesity crisis, but experts say that high-fructose corn syrup doesn't pave the way for weight gain any more than other sweeteners do. "From a biochemical standpoint, it's no different from sucrose, or table sugar," says Marion Nestle, PhD, a professor of nutrition, food studies, and public health at New York University and a coauthor of Why Calories Count: From Science to Politics. "It has the same number of calories, and the body processes both of them the same way."
The problem is that high-fructose corn syrup is extremely cheap, so manufacturers add it to countless products. As a result, Americans are consuming more of the sweet stuff than ever before. The bottom line: Limit your consumption of all added sugar, which can appear on labels as "dextrose," "maltose," "beet sugar," and "fruit juice concentrate."
Myth: Fried food makes you fat. The real deal: "Deep-frying can be just as healthy as sautéing," says Harold McGee, a food-science writer and the author of On Food and Cooking: The Science and Lore of the Kitchen. "When properly deep-fried, food soaks up minimal oil." Case in point: A chicken leg contains only 16 calories more when fried than it does when roasted. That's because the intense heat causes moisture inside the food to evaporate, creating steam pressure that blocks oil -- and calories -- from entering. To create this effect, the oil needs to be between 325 and 350 degrees for larger pieces of food, like chicken, and 375 to 400 degrees for smaller items, such as potato wedges. To know when the proper temperature has been hit, use a deep-frying or candy thermometer.
Myth: Loading up on fruit helps you slim down. The real deal: Some weight-loss plans consider fruit a freebie that dieters don't have to factor into their daily tally. But just because grapes are loaded with nutrients doesn't mean you should graze on them all day. "Fruit is high in vitamins and fiber," Taub-Dix says. "But it still contains calories and sugar." A banana, for instance, has roughly the same number of calories -- around 100 -- as two chocolate-chip cookies.
If you're trying to slim down, Taub-Dix recommends that you stick with four servings (a half cup or a piece of fruit counts as one) a day and pair each serving with some protein. "A handful of nuts or a cup of Greek yogurt will slow down digestion and keep your blood sugar levels steady," she says.

The Best Fat-Burning Workout for a Packed Gym


The best fat-burning workout for a packed gymIt's January, and you're ready to ramp up your results this year…but the gym is so packed that you can't even get to your favorite equipment. No worries-we've got your back. When it comes to getting in amazing shape in the shortest amount of time, you can't beat metabolic resistance training (MRT), a type of workout that maximizes caloric expenditure while also increasing your metabolic rate. The basic principles of MRT involve working in a circuit with little to no rest in between moves.
Studies have shown that MRT can help boost your calorie burn both during and up to 38 hours after your workout is over! Do this simple, small-space friendly routine at the gym or at home up to four non-consecutive days per week for best results.

How it works: Perform each set of moves in a circuit (back to back with little to no rest in between). Rest 60 to 90 seconds in between in each circuit, repeating the circuit 3 times total.
You will need: Free weights
Side lunge pressSide lunge press1. Side lunge front v-raise: Stand with feet together, holding dumbbell in right hand. Step right foot out and lower into a side lunge, reaching hands to the floor on either side of right foot [A].
Push off right leg and bring feet together as right arm presses dumbbell overhead with palm facing in. Repeat, lowering right arm down as right foot steps back out into side lunge [B]. Repeat on opposite side.

Single-leg squat rowSingle-leg squat row2. Single-leg squat row: Stand on left leg, holding dumbbell with left hand, right leg bent and right foot lifted slightly off the floor behind body. Bend left knee and squat down, hinging forward at hips and reaching arms down towards the floor, keeping spine straight [A].
Bend left elbow behind body and pull dumbbell into side of torso [B]. Extend left arm and return to starting position. Do 12 reps; repeat on opposite side. If you have trouble balancing, try this move in a split stance instead, with the back foot lightly tapped on the floor for stability.
Diamond pushupDiamond pushup3. Diamond pushup: Begin in plank position with feet slightly wider than hip width and hands together directly under chest, forming a diamond shape [shown]. Keeping abs drawn into spine, bend elbows and lower chest as close to the floor as possible without sagging through hips (elbows stay close to sides). Return to start. Modify on knees if needed.
Cross chopCross chop4. Cross chop: Stand with feet wider than hip width, holding dumbbell. Bend elbows and raise dumbbell to right shoulder (as if winding up to hit a baseball with a bat), rotating torso to the right, lifting left heel off the floor in preparation for the chop [A].
Engage abs and quickly lower dumbbell down and across to left knee, rotating torso to the left and lifting right heel to lower into a left lunge [B]. Immediately return to start. Do 12 reps; repeat on opposite side.

Public Talk at the University of Virginia on Friday, January 17

This Friday, I'll be giving an invited lecture at the University of Virginia, my undergraduate alma mater.  I was kindly invited by a medical student named Robert Abbott, and it worked out well because I was already traveling to Charlottesville.

The talk will be titled "Why Do We Overeat?  A Neurobiological Perspective".  Here's the teaser:
Obesity is a leading cause of morbidity and mortality in industrialized nations, yet this is a relatively recent phenomenon.  In the United States, increasing obesity prevalence has paralleled a gradual increase of daily energy intake.  Why do most Americans eat more than we used to, and more than we need to maintain a lean state, despite negative consequences?  This presentation will touch on the neurobiology of action selection, the neurobiology of energy homeostasis, and why our central nervous system hardware may not be up to the task of constructively navigating the modern food environment.
The talk will be attended by medical students, but I also hope to have some doctors and researchers show up, as well as people from the broader Charlottesville community.  It will be a thought-provoking talk regardless of your background, and it will touch on some of my own work.

The talk will be held in the main medical school auditorium, MEB 3110, on Friday, January 17 at noon.  You can find driving directions and parking information by following this link.  You'll probably have to park in a parking garage, either the Lee Street or Central Grounds garage (directions in the link).

For a map of the UVA health system, follow this link.  The Medical Education Building is number 44 on the map, and the talk will be in room MEB 3110 on the 3rd floor of the building.

See you there!

10 Things Your Feet Say About Your Health

What can your toes tell you? The nurse just took your temperature, checked your blood pressure, and even made you step on the scale (with that heavy sweater on, no less). And as she hands you the paper gown, she gives her final directive: "You can leave your socks on."
When it comes to your health, that could be a big mistake. A change in your feet--whether on the skin, nails, or even how they feel--can be the first sign of a potentially serious problem that, if caught early, could save your life. "Our feet are the first parts to be affected by nerve issues because they're the farthest from our hearts and spine," explains Carolyn McAloon, DPM, a Bay Area podiatrist and president of the California Podiatric Medication Association. Even more reason to never ignore feet: They're easily compromised when our bodies feel threatened, since we send blood to the internal organs and the brain before the extremities.
Here, we reveal what could be lurking behind your most common foot concerns. If you see something familiar on the list, it's best to get it checked by your doc or podiatrist before attempting any treatment. 
Hairless feet and toes
What it might mean: Serious circulation problems

Sure, it's a pain during sandal season, but hair on your toes is a good thing. Sudden baldness can be a sign that your feet aren't getting enough blood flow to sustain hair growth. Expect your doctor to check for a pulse in your feet, which is another indication that your heart may not be able to pump enough blood to your feet, says Dr. McAloon. (Feet aren't your only cue to poor circulation. Read 8 Weird Health Tricks From Your Hands for more tips.)

Frequent foot cramping
What it might mean: Dehydration and nutritional deficiencies

Randomly occurring cramps are about as generic as foot problems get. They can be as serious as circulation and nerve issues, or as harmless as a nutritional deficiency. If you're exercising, be sure to drink plenty of water, since dehydration often leads to muscle cramping. You might also try upping your intake of potassium, magnesium, and calcium (with your doctor's go-ahead, of course), since their deficiencies make cramps more common. "For relief, soak feet in a warm foot bath and stretch your toes toward your nose, not pointing down," says Dr. McAloon. If the cramps don't let up, see your doctor for testing to rule out circulation issues or nerve damage.
A sore that won't heal
What it might mean: Diabetes or skin cancer

Stubborn sores are red flags for diabetes. Uncontrolled glucose levels in the blood can lead to nerve damage all the way down in your feet, which means any cut, sore, or scrape can come and go without you ever feeling it. And if it gets infected, the most serious cases may call for amputation.
A non-healing wound can also be a sign of skin cancer, says Dr. McAloon. Melanoma can pop up anywhere on your body--even in between your toes--so be sure to include your feet in your regular skin checks. (Brush up on your mole-detecting skills here.)
Perpetually cold feet
What it might mean: Hypothyroidism

Hypothyroidism is the most common cause of feet that just can't get warm. And if you're over 40, you could be living with a sluggish thyroid without even knowing it. Unfortunately, cold feet are the least of your problems--hypothyroidism can also cause hair loss, fatigue, unexplained weight gain, and depression. Get your feet feeling toasty again by heading to your doc for a simple blood test, and you'll start warming up shortly after starting the daily medication.
Suddenly enlarged big toe
What it might mean: Gout or other inflammatory issue

"The sudden onset of a red, hot, swollen, and painful joint requires immediate medical attention," says Dr. McAloon. Typical causes include gout, inflammatory arthritis, infection, or trauma.

Numbness
What it might mean: Peripheral neuropathy or a pinched nerve

Numbness in both feet is known as peripheral neuropathy, caused most commonly by diabetes, chronic alcoholism, or a side effect of chemotherapy. If you're experiencing neuroma, or numbness in only one foot, it could be due to a pinched nerve in the foot, ankle or back. That's most likely caused by years of wearing tight shoes (we mean you, stiletto devotees.)
Bunions
What it might mean: Inherited faulty foot structure

If you thought your bunions were caused exclusively by a closet full of gorgeous (yet restrictive and often painful) shoes, you can stop blaming the boutique. Bunions are actually a sign of a flawed foot structure that's often inherited and merely aggravated by inappropriate shoes. "The first foot bone drives toward the middle of the body, and you see the bump," explains Dr. McAloon. It can be painful and unsightly, but the only way to really correct it is with surgery.
Heel pain
What it might mean: Plantar fasciitis

You can't mistake it--that sharp pain in the bottom of the heel when you get out of bed or stand up from a chair. It's a strain of the ligament that supports you arch. And whether you did it by wearing too-tight shoes, walking in flip-flops, or wearing worn-out workout sneakers, the longer you let it go, the longer it takes to heal. Your podiatrist will probably tell you to ease up on your workout at first, rethink your footwear, and adopt a good stretching routine. 
Flaky, itchy, or peeling skin
What it might mean: Fungal infection

Even if you're never donned an athletic jersey in your life, you could still be walking around with athlete's foot--the euphemistic term for a fungal infection. The most common cause of itchiness and peeling, it can be treated by applying anti-fungal cream and keeping your feet as cool and dry as possible during the day. If you're fungus-free, you might be dealing with eczema or psoriasis--both to be determined by your podiatrist through a skin sample.

Yellow toenails
What it might mean: Fungus or pedicure overload

Seeing yellow when you look down? Don't freak out--especially if you've been wearing nail polish for months on end without a break. "Yellowness can also happen naturally with age," says Dr. McAloon. If it's accompanied by brittleness or flaking, it's most likely you have a fungal infection like athlete's foot.

Free e-Book and Ideal Weight Program 2.0 Announcement


I'm happy to announce that we're releasing a free e-book titled Why do We Gain Fat, and How do We Lose it? An Introduction to the Science of Body Fat, by Dan Pardi and myself. This is a slimmed-down version of the longer, fully referenced e-book we offer as part of the Ideal Weight Program. In it, we provide a succinct overview of the science of body fat gain and loss, and the evidence base for our program.  It also contains a schematic that ties together the various concepts in visual form. You can download it from the Dan’s Plan site by following this link to our program overview page.

Ideal Weight Program 2.0 Upgrades

Over the last year, Dan and I have been working hard to improve the Ideal Weight Program, both in response to user feedback and our own ideas for development.  Here are some of the new features we offer in 2014:
  1. Four-week meal plans and shopping lists for the FLASH diet and the Simple Food Diet, as requested by Ideal Weight Program users.  This is in addition to the recipes and cooking guides we already provide.  
  2. The Protein Unit system.  Research suggests there's an optimal amount of protein for appetite control and fat loss, depending on your height, weight, gender, and physical activity level.  Our fat loss diets are high in protein, but how do you know you're getting the right amount?  We've created a calculator that does it for you automatically, and explains how to apply your personalized Protein Unit value easily and intuitively using real food. 
  3. Diet plates.  These are visual guides to following our diets, based loosely on the intuitive USDA MyPlate design.  
  4. Cheat sheets.  Put these on your fridge to remind yourself of your diet and lifestyle guidelines, and daily protein unit goal.
  5. Updated guidance.  We've refined a few things in the diet guidance documents. 

At a time of year when many people want to shed excess holiday pounds and start down a leaner, healthier path, we offer the Ideal Weight Program 2.0.  The program comes with a 30-day no-questions-asked refund policy so you can try it without risk.  We think you'll love this program, but if it doesn't work for you, we're happy to refund your purchase price. 







Financial disclosure: I receive a portion of the revenue from the sale of the Ideal Weight Program.  I do not receive revenue from the sale of other products associated with Dan's Plan or the Ideal Weight Program (such as the Fitbit, cooking tools, and other programs).
