More People May Benefit From Going Gluten-Free


Avoiding troublesome foodstuffs helps even those without celiac symptoms, study finds

SUNDAY, May 8 (HealthDay News) -- People at risk for celiac disease ought to be screened for the disorder, even if they show no symptoms, a new study suggests.
Celiac disease is a disorder that causes digestive problems in the small intestine when the person consumes gluten, a protein found in wheat, rye and barley. The number of U.S. residents with the disease has grown rapidly in recent decades, but, according to the study authors, an estimated 2 million people have the disease but do not know it.
For the study, researchers screened 3,031 healthy people who were related to someone with celiac disease, but had no symptoms themselves, and selected 40 people who tested positive for antibodies specific to celiac disease. By random selection, members of that group were either put on a gluten-free diet or told to continue with their normal diet, containing gluten.
People on a gluten-free diet reported improved gastrointestinal health as well as an overall improvement in their health-related quality of life, compared with the others, according to the study.
"We found that regardless of the clinical presence of celiac disease, most screen-detected patients benefitted from early treatment of a gluten-free diet," Dr. Katri Kaukinen, from the gastroenterology department at Tampere University Hospital and School of Medicine in Finland. Her team was scheduled to present the findings Monday in Chicago at the Digestive Disease Week conference.
"In addition, the results showed that endomysial-antibody positive patients had an evident gluten-dependent disorder and, therefore, it could be argued that detection of antibody positivity could be sufficient for the diagnosis of celiac disease," she explained in a meeting press release.
After the study, 85 percent of the participants were willing to maintain a gluten-free diet, and 58 percent viewed their screening for celiac disease in a positive light, the researchers said.
"Based on our results, an intensified serological screening of at-risk populations of celiac disease is encouraged," Kaukinen said. "However, more research needs to be done before expanding screening to the general population."
Experts note that research presented at meetings should be considered preliminary because it has not been subjected to the rigorous scrutiny given to research published in medical journals.

Spices and Herbs: Their Health Benefits


Everyday herbs and spices may do more than enhance the flavor of food.
Common herbs and spices may help protect against certain chronic conditions, such as cancer, diabetes, and heart disease.
Herbs, including basil and parsley, are from plants and plant parts. Spices often come from the seeds, berries, bark, or roots of plants.
Seasonings, such as cinnamon, often lead lists of commonly eaten foods with the highest levels of measured antioxidant activity.
“Studies show that many different herbs and spices offer health benefits,” says David Heber, MD, PhD, professor of medicine, and director of the UCLA Center for Human Nutrition. Most of the evidence exists for cinnamon, chili peppers, turmeric, garlic, oregano, basil, thyme, and rosemary, Heber tells WebMD.
Polyphenols, a type of plant compound, provide one of the main health benefits associated with herbs and spices. Polyphenols are also abundant in certain fruits and vegetables, tea, and red wine.
Certain herbs and spices curb inflammation in the body, which may give rise to heart disease and cancer. For example, antioxidants in cinnamon have been linked to lower inflammation, as well as reductions in blood glucose concentrations in people with diabetes.

Savor the Flavor, Reap the Rewards

Liberally seasoning your food with herbs and spices may also help if you use them in place of other flavor boosters.
“Using herbs and spices expands your palette without extra calories and may decrease the amount of salt, fat, and sugar you use without sacrificing flavor,” says Kate Geagan, MS, RD, author of Go Green,Get Lean: Trim Your Waistline with the Ultimate Low-Carbon Footprint Diet.
The proposed Dietary Guidelines for Americans 2010 suggests that adults limit their sodium intake to 1,500 milligrams a day to manage high blood pressure and reduce the risk of developing the condition. If the guidelines are adopted, nearly all Americans will need to find alternatives to salt and other sodium-based additives.
Seasonings may even play a part in weight control.
“Tastier foods are more satisfying than bland ones, which you tend to eat faster, and with less fulfillment,” Heber says. If you’re not satisfied, you’re more likely to overeat.
According to Heber, dihydrocapsiate, a compound in chili peppers, boosted fat-burning capacity when people ate it three times a day during a study. And a recent study in Cell Metabolism showed that consuming capsaicin, the ingredient in chili peppers that provides heat, lowered blood pressure in lab animals.
Research about the therapeutic effects of herbs and spices is enticing, but how does it translate to what you eat every day? 
Quite easily, as a matter of fact. It turns out that relatively small amounts of dried and fresh herbs and spices may have health benefits.
For example, Heber says it’s reasonable to expect benefits from 1.5 teaspoons of ground cinnamon. Spread it throughout the day to make it most palatable.
“Use herbs and spices at their peak to get the most out of them,” Geagan says. “The active compounds in herbs and spices degrade with time.”
Capitalize on the potency of dried herbs and spices by purchasing brands with “Best By” dates on them, and storing them in airtight containers away from heat, moisture, and direct sunlight.
Using fresh herbs or spices? Double the amount to get the same levels of active substances in their dried counterparts, Heber says.

Herbs and Spices: A Little Goes a Long Way

You don’t need to make drastic changes in your eating plan to benefit from seasonings. Here’s how to incorporate more herbs and spices into your favorite foods.
Ground cinnamon:
  • Add 1.25 teaspoons to prepared oatmeal; 1 cup Greek yogurt mixed with 2 teaspoons molasses or honey, or artificial sweetener; and French toast batter.
  • Sprinkle half a teaspoon of cinnamon over ground coffee before brewing.
  • Top a fat-free latte or hot cocoa with ground cinnamon.
Chili peppers: Add chopped peppers to chili, burgers, soups, stews, salsa, and egg dishes.
 Turmeric: 
  • Sprinkle on egg salad.
  • Mix half a teaspoon turmeric with 1 cup Greek yogurt and use as a dip or sandwich spread.
  • Add to chicken or seafood casseroles, and to water when cooking rice.
Garlic: Add fresh chopped or minced garlic to pasta dishes, stir-fry dishes, pizza, fresh tomato sauce, and meat and poultry recipes. 
Oregano:
  • Add 1/8 teaspoon dried to scrambled eggs, salad dressings, and store-bought or homemade marinara sauce.
  • Sprinkle some on top of pizza, and stir into black bean soup.
 Basil: Make a sandwich with low-fat mozzarella cheese, sliced tomatoes, and fresh basil leaves; add fresh leaves to green salads.
Thyme:
  • Sprinkle dried thyme onto cooked vegetables in place of butter or margarine.
  • Add 1/8 teaspoon dried thyme to two scrambled eggs, and to salad dressings.
  • Use it in a rub when cooking salmon.
  • Add fresh thyme to chicken salad and chicken soup.
Rosemary: Add dried crushed rosemary to mashed potatoes and vegetable omelets.
Parsley: Add chopped flat leaf parsley to meatballs and meat loaf, and to bulgur salad.
Ginger:
  • Grate fresh ginger into quick bread batters and vinaigrette.
  • Add chopped ginger to stir-fries. Sprinkle ground ginger on cooked carrots.
Cloves: Sprinkle ground cloves on applesauce, add to quick bread batters, and add a pinch to hot tea.

Restaurant Foods Win 'Awards' for Most Calories


Milkshake
July 19, 2011 -- What has 1,540 calories, 59 grams of saturated fat, and weighs nearly three-quarters of a pound? A single slice of the Cheesecake Factory's Ultimate Red Velvet Cake Cheesecake, a winner of one of this year's Xtreme Eating Awards from the Center for Science in the Public Interest (CSPI).
The CSPI, a consumer health advocacy organization, named the seven "dishonorees" at a news conference. Eight awards were given; the Cheesecake Factory received two.
"It's as if the restaurants were targeting the remaining one out of three Americans who are still normal weight in order to boost their risk of obesity, diabetes, [and] heart attacks," CSPI Nutrition Director Bonnie Liebman says in a news release.

Xtreme Eating Winners

In addition to the Red Velvet Cake, the winners include:
The Farmhouse Cheeseburger. Topped with pork belly and a fried egg, it weighs in at 1,530 calories with 36 grams of saturated fat. The fries served with it add an additional 460 calories and 1,460 milligrams of sodium. (Cheesecake Factory).
PB&C Shake. This 24-ounce peanut butter and chocolate ice cream shake has 2,010 calories and 68 grams of saturated fat. That's a full day's recommended calories and three and half days' recommended saturated fat, the CSPI points out. (Cold Stone Creamery).
Provolone-Stuffed Meatballs with Fettuccine. Served with garlic bread, this meal packs 1,520 calories, 43 grams of saturated fat, and 3,700 milligrams of sodium onto your plate. (Applebee's).
Great Fries. An extra large order is about 1 1/3 pounds. It has 930 calories and nearly 2,500 milligrams of sodium. That's before it's dressed up in an assortment of toppings, including cheese, bacon, chili, and sour cream. (Great Steak).
Monster Bacon 'N Beef Cheeseburger. The bacon is blended into the two ground beef patties for a total of 1,250 calories and 42 grams of saturated fat. A side of 300-calorie fries, 620-calorie onion rings, or 80-calorie fruit salad completes the plate. (IHOP).
Fried Cheese Melt. Four fried mozzarella sticks, melted American cheese, sourdough bread, and a side of fries give diners a meal that has 1,260 calories, 21 grams of saturated fat, and 3,010 milligrams of sodium. (Denny's).
Porterhouse Steak. This 1 1/2 pound piece of beef comes with 1,390 calories, 36 grams of saturated fat, and 1,200 milligrams of sodium. Want mashed potatoes and creamed spinach with that? The calorie count nearly doubles, to 2,570, while the fat shoots up to 85 grams and the sodium to 2,980 milligrams. (Morton's The Steakhouse).

Calorie Counts on Menus

Soon, you may be able to view those calorie counts on restaurant menus. In April, the FDA proposed a regulation that would require calorie labeling in chain restaurants, retail food establishments, and vending machines.

"Perhaps calorie labeling will usher in a new era of common sense at America's chain restaurants, and chains will compete with each other to come up with new, healthy menu items with more vegetables, fruits, and whole grains," CSPI Executive Director Michael F. Jacobson says in a news release.
According to Nancy Mays, a spokeswoman for  Applebee's, the restaurant chain offers nutritional information online and in the restaurant.
"We offer a lot of great-tasting dishes, including six Unbelievably Great Tasting and Under 550 Calories selections and five Weight Watchers-endorsed entrees," Mays says in a statement.
Cold Stone Creamery also offers lower-calorie menu items, says spokeswoman Jean Smoke in a statement, including "Sinless Ice Cream and Non-Dairy Sorbet, and ... at least one flavor of low-fat frozen yogurt that starts at 34 calories an ounce."
Smoke, also speaking on behalf of Great Steak, says that while Great Steak does offer some lower-calorie sides and salads, "We serve a consumer who is looking for true comfort food. Comfort food will oftentimes involve high-calorie items."
The National Restaurant Association, which says in a statement that it advocated for the menu labeling law, points out in the same statement that "restaurants have and will continue to offer a growing selection of healthful menu options."
To the CSPI, such limited nods to healthy eating are not enough.
"Instead of setting aside a few menu items called something like 'Lean & Fit,' why can't menus have a small section called 'Fatten Up!' and keep the rest of the menu healthy?" Jacobson asks in a news release.

Seven Diet Sins

The most common nutrition mistakes -- and how to avoid them.
  • Assuming your choices are better than they actually are.
  • Being confused about carbs.
  • Eating too much.
  • Not eating enough -- or often enough.
  • Taking too many supplements.
  • Excluding exercise.
  • Believing everything you read about nutrition and weight loss.
You read all the books; buy all the right vitamins; you know the buzzwords to look for on food labels. By all standards, you're certain your nutrition report card should be filled with straight A's.
But before you start pasting gold stars onto your refrigerator door, take heed: Nutrition experts say most of us think we are eating a lot better than we actually are.
"It's easy to buy into some pretty popular nutrition misconceptions -- myths and half-truths that ultimately find us making far fewer healthier food choices than we realize," says New York University nutritionist Samantha Heller, MS, RD.
To set the record straight, Heller and two colleagues from the American Dietetic Association gave us the dish on seven nutrition mistakes you probably don't know you're making -- along with sure-fire ways to avoid them.

Mistake No. 1: Assuming your choices are better than they actually are.

From fruit juices to canned vegetable soup, breakfast muffins to seven-grain bread, it's easier to think your food choices are healthier than they really are, experts tell WebMD.
"If a label says 'Seven-Grain Bread,' it sounds pretty healthy, right? But unless that label also says 'whole grains' it's not necessarily going to be the healthiest bread choice you could make," Heller says.
Likewise, she says many folks think that eating a can of vegetable soup is as nutritious as downing a plateful of veggies -- not realizing how few vegetables are inside, and how much of the nutrients are lost in processing.
Another common mistake: Substituting fruit juices for whole fruits.
"Are fruit juices healthier than soda? Yes. But they are also concentrated sources of sugar that don't give you anywhere near the same level of nutrients you get from whole fruits," says Bonnie Taub-Dix, MA, RD. What's more, says Taub-Dix, if you're trying to lose weight, you won't get the same sense of fullness from a glass of juice that you will from a piece of fruit.
"Instead, you'll just take in a whole lot of calories -- and still feel hungry," Taub-Dix says.
The solution: Whenever possible, eat whole, fresh, and unprocessed foods. Even when you eat them in smaller amounts, you're likely to get a well-rounded group of nutrients. When buying packaged foods, put in at least as much time into reading labels and selecting products as you do when choosing a shower gel or shampoo.
"Don't just assume a product is healthy -- even if it's in the health food section of the supermarket," says Heller. "You've got to read the labels."

Mistake No. 2: Being confused about carbs.

A national fascination with low-carb diets has many Americans eliminating carbohydrates from their eating plans in record "grams." But before you reconstruct your personal nutrition pyramid, there's something you should know.
"There are carbs that are very, very good, and some that are less good, but your brain and body must have some carbohydrates every day," says Heller.
Moreover, because complex carbohydrates (those rich in whole grains and fiber) keep you feeling full longer, they also help you to eat less -- and lose more!
But eliminating this important food group isn't our only carb-related mistake. According to dietician Rachel Brandeis, MS, RD, just as troublesome is the belief that all no-carb or low-carb foods are healthy, or that you can eat them in any amount.
"Much like the low-fat diet craze, where everyone thought that if a meal had no fat, it had no calories, similarly people have come to believe that if it has low carbs you can eat as much as you want and not gain weight," says Brandeis. "And that is simply not true." Eat enough of anything, she says, and you'll gain weight.
The solution: Experts say you should never cut any food group out of your diet -- including carbohydrates. Equally important, says Heller, is to learn which carbohydrates give you the biggest bang for your nutritional buck.
"It's a lot harder to run amuck when you are including carbohydrates like fresh fruits and vegetables and whole grains in your diet," says Heller.

Mistake No. 3: Eating too much.

Whether you're filling your plate with low-fat, low-carb, or even healthy, nutritionally balanced foods, overestimating how much food your body needs is among the most common mistakes, experts say.
"Many people believe they should feel not just satisfied after a meal, but stuffed," says Heller. "I think many of us have lost touch with the sensation of having had enough food."
Adds Taub-Dix: "People also tend to believe that they can eat larger portions if all the food on their plate meets the guidelines of their current diet -- such as low-carb or low-fat -- and that, of course, is also not true."
The solution: Remain conscious of portion sizes. Weigh and measure standard portions, at least at first, so you'll know what the amounts should look like. And, says Brandeis, "never use restaurant portions as your guide -- they super-size everything."

Mistake No. 4: Not eating enough -- or often enough.

While overeating and undereating may seem like contradictory nutrition mistakes, they are related.
"If you don't eat at regular intervals throughout the day, you risk disrupting your blood sugar and insulin levels, which in the end can promote fat storage and lower your metabolism -- both of which lead to weight gain," Brandeis says.
The solution: Eat something every four hours and never let yourself "starve" from one meal to the next, Brandeis says.

Mistake No. 5: Taking too many supplements.

"People tend to forget that a vitamin pill is a supplement -- it's meant to complement your diet, not act as a stand-in for the foods you don't eat," says Heller. What's more, she says, taking too many vitamins can end up sabotaging your good health.
"Every vitamin and mineral and phytochemical in our body works in concert with one another, and it's easy to knock that balance off if you are taking concentrated doses of single nutrients, or even groups of nutrients," says Heller.
Bradeis cautions that any diet plan that claims you must take a high-potency supplement to meet your nutritional needs should send up a red flag.
"It means that eating plan is not healthy," says Brandeis, "and it also means you are going to miss out on the synergistic health effects that can only come from whole foods -- including not only helping you to feel fuller longer, but also preventing cellular breakdowns important to preventing disease."
The solution: Both experts recommend taking no more than one all-purpose multivitamin daily. Don't supplement your diet with individual nutrients without the guidance of your doctor, nutritionist, or other health expert. Keep in mind that the sales clerk in the health food store is usually not a health expert.

Mistake No. 6: Excluding exercise.

While most folks believe nutrition is all about food, Brandeis says it's also about how your body uses food -- and that's where regular exercise comes in.
"Without adequate exercise, you cannot maintain a high enough metabolic rate to burn your food efficiently," says Brandeis. "A pill can't do that for you; foods alone can't do that for you. Exercise is the only way to achieve it."
The solution: Make exercise a regular part of your life. And don't get hung up if you can't do it at the same time every day. If you miss your routine in the morning, don't wait until the next day and try to do twice as much. Instead, try to fit in some exercise -- even if it's just a little bit -- every day, says Taub-Dix.

Mistake No. 7: Believing everything you read about nutrition and weight loss.

"Just because someone writes a diet book or a nutrition guide does not mean they are an expert," cautions Brandeis.
If you're turning to a book for guidance, she says, "look to the author's credentials and ask yourself: Is this person a dietician; do they have an advanced degree in nutrition? Or are you buying this book because it's written by a celebrity who you think looks good?"
Even if an "expert" is behind your nutrition or diet plan, Brandeis says, it's important to make sure the plan is based on solid research.
"Has the plan been tried on 20 people or 200 people? Have the results been published in a peer-reviewed medical journal -- or is it based solely on anecdotal reports? These are things that I fear many people don't pay attention to before paying attention to what is being said -- and that is a huge mistake," says Brandeis.
Perhaps even more important: Experts say there is no one diet or nutrition plan that is right for every person.
Brandeis tells WebMD that dieters need to stop blaming themselves when a plan doesn't work for them. It's not them, she says. It may not even be the plan. "It's just not the correct match," she says.
The solution: Before following a particular diet or nutrition plan, check the credentials of the author or creator. Look for plans that are backed up by published medical data, and supported by the opinions of many experts in the field.

Barbeque May Contain Hidden Dangers

SUNDAY, July 17 (HealthDay News) -- Backyard barbeques are a big part of summer fun, but avoiding their hidden dangers is key to staying healthy and enjoying a cookout, a doctor suggests.
Barbeques can result in food poisoning from raw or undercooked foods; temperamental grills can cause burns; and charred meat may contribute to the development of certain types of cancer, according to Dr. Martha Howard, a Chicago Healers practitioner.
But it doesn't have to be that way, Howard noted in a news release from the health care network. As the summer heats up and more people fire up their grills, Howard offers the following tips to help ensure safe and healthy barbeques:
  • Keep it clean. Be sure to scrub the grill and remove old fats.
  • Use wood starters for charcoal -- not petroleum. Stack charcoal in a two-pound metal can with the ends cut off. Spread out the coals with tongs once they are well-lit.
  • Become familiar with the grill. It's important to know how to operate and turn off a propane grill safely.
  • Use proper hygiene. Remember to wash your hands and use separate plates and cutting boards for raw and cooked meats.
  • Use marinades. Marinated meat may char less. Just don't let meat sit out while it's marinating.
  • Precook. Avoid taking meats or poultry directly from the freezer to the grill. Precooking before grilling reduces overall cooking temperature and charring.
  • Cut down to size. Cut meat and chicken into smaller pieces so they cook thoroughly.
  • Check temperatures. To avoid food poisoning, check temperatures with a meat thermometer: chicken, 165 degrees; hamburger, 160 degrees; pork, 150 degrees; hot dogs, 140 degrees; steak, 160 degrees for medium.
  • Don't allow meat to become charred. Charred meat contains three potentially cancer-causing chemicals: PhIP, HCAs (heterocyclic amines) and PAHs (polycyclic aromatic hydrocarbons).
  • Trim the fat. Less fat on meat and poultry means fewer PAHs.
  • Try more vegetables. Vegetables can be grilled for a healthy alternative to meat.
  • Turn it off. At the end of the barbecue, be sure to put out charcoal completely, or turn the propane valve off.

Binge Drinking May Affect Memory of Teens

By Jennifer Warner
WebMD Health News

Teens drinking alcohol
July 15, 2011 -- Binge drinking may have lasting effects on the still-developing brains of teenagers.
A new study shows that long after the hangover wears off, binge drinking impairs the spatial working memory of teenagers. Girls appear especially vulnerable to these effects.
Spatial working memory is the ability to perceive the space around you, remember, and work with this information to perform a task, such as using a map, playing sports, or driving a car.
"Our study found that female teenage heavy drinkers had less brain activation in several brain regions than female non-drinking teens when doing the same spatial task," says researcher Susan F. Tapert, acting chief of psychology at the VA San Diego Healthcare System, in a news release. "These differences in brain activity were linked to worse performance on other measures of attention and working memory ability."
"Even though adolescents might physically appear grown up, their brains are continuing to significantly develop and mature, particularly in frontal brain regions that are associated with higher-level thoughts, like planning and organization," says Tapert. "Heavy alcohol use could interrupt normal brain cell growth during adolescence, particularly in these frontal brain regions, which could interfere with teens' ability to perform in school and sports, and could have long-lasting effects, even months after the teen uses."
The study is published in Alcoholism: Clinical and Experimental Research.

Lingering Effects of Teen Binge Drinking

In the study, researchers compared the performance of 40 teenage binge drinkers and 55 non-drinking teenagers on a working spatial memory task on a computer. Functional magnetic resonance imaging (fMRI) scans of the participants' brains were taken during the task to show differences in brain activity.
The results showed binge drinking was associated with gender-specific differences in brain activation during the working spatial memory task. Male binge drinkers showed greater activation in all brain regions during the task while female binge drinkers showed less activation than non-drinkers.
For female teenage binge drinkers, these differences correlated with worse performance on the working spatial memory task as well as poorer sustained attention.
Among male teenage binge drinkers, greater activation in the brain translated to better spatial memory performance.
Researchers say the results suggest that teenage girls may be more vulnerable to the toxic effects of binge drinking on the brain while males may be more resilient.
"Females' brains develop one to two years earlier than males, so alcohol use during a different developmental stage -- despite the same age -- could account for the gender differences," Talpert says. "Hormonal levels and alcohol-induced fluctuations in hormones could also account for the gender differences. Finally, the same amount of alcohol could more negatively affect females since females tend to have slower rates of metabolism, higher body fat ratios, and lower body weight."
Researchers say these gender differences for the effects of teenage binge drinking on brain development merit further study.
"These findings remind us that adolescent boys and girls are biologically different and represent distinctive groups that require separate and parallel study," says researcher Edith V. Sullivan, PhD, professor in the department of psychiatry and behavioral sciences at Stanford University School of Medicine, in the news release.
"And yet binge-drinking is a dangerous activity for all youth," says Sullivan. "Long after a young person -- middle school to college -- enjoys acute recovery from a hang-over, this study shows that risk to cognitive and brain functions endures. The effects on the developing brain are only now being identified. 'Why tamper with normal developmental trajectories that will likely set the stage for cognitive and motor abilities for the rest of one's life?'"
