Fat Chance - New Clues to Why We Gain Weigh

We live surrounded by a 24-hour , all-you-can-eat buffet. And yet some people manage to stay lean while everyone else gains weight. Is it will power? Genes? Metabolism?"Given teh world we live in, the real question isn't why people get fat, but why some people manage to stay thin," says obesity researcher Eric RavussinHere are some purprising new leads into what packs on the extra pounds...and how to keep them off: LeptinQ. What do we know about obesity that we didn't know 20 years ago?

Beyond Bread -- Think Thin

White, wheat, or rye? Years ago, that was pretty  much all you had to decide in the bread aisle.Now sliced bread has to share shelf space with a growing cadre of wraps, flat-breads, pitas, naans, bagels, English muffins, and other breadoids. More are whole grain (if not 100 percent) and higher in fiber (if not the best kind) than ever before. And many are thinner, which is a boon for consumers who aim to stay that way themselves. Thinner also means they're lower (if not low) in sodium. 

Exercise Maintains Cognitive Functioning in Older Adults

Older adults who participated in a moderate exercise program for 1 year improved cognitive functioning, according to a study published in Frotneirs in Aging Neuroscience (2010; 2 [Article 32], 1-17; doi:10.3389/fnagi.2010.00032). To compare the cognitive effects of aerobic training with those of stretching, toning and balance (STB) training among older adults, researchers from the University of Illinois at Urbana-Champaign recruited 65 subjects ranging in age from 59 to 80 years. Subjects reported having engaged in very little physical activity in the previous 6 monhts.

Nutritional Necessities: Before, During & after Exercise

1. Before ExerciseFluids: Drink at least 8 ounces of fluids prior to exercise.Meal: Eat a meal at least 4 hours prior to exercise so that the body uses carbohydrates proplery.Snack: Ideally, consume a snack 30-90 minutes prior to exercise; include 30-60g of carbohydrates, plus 5-10g or protein to provide energy for prolonged stamina and to decrease exercise-induced muscle protein breakdown. 2. During Exercise

A Few Stress and Obesity Hormones

EpenephrineAlso known as adrenaline. It is secreted by the adrenal medulla in response to stress and acts on all body tissues. When produced in teh body, it participates in teh fight-or-flight response of the sympathetic nervous system by stimulating several physiological processes.  Norepinephrine

Keen One

"Quino: An Emerging 'New' Crop with Potential for CELSS," read the title of the 1993 NASA Technical PAper. The U.S. space agency was considering Quicno (pronounced Keen-wah) for teh "Controlled Ecological Life Support Symstem" -- that is, for "meeting the needs of humans on long-term space missions."

5 More Common Food Goofs!

6. If it has Vitamins, it must be good for me.It started 40 years ago with breakfast cereals ("fortified with 8 vitamins and iron"), Wonder Bread ("helps build strong bodies 12 ways!"), and sugary kids drink like Hi-C, and Sunny D ("100% vitamin C").Now vitamins are also being added to cereal bars, evergy and granola bars, and sugary drinks for adults. And we keep falling for it. 

5 Common Food Goofs!

It's easy to make mistakes when it comes to buying food. (even teh most seasoned nutrition mavens, who should know better, occasionally screw up.)Maybe you didn't notice that the reducted-fat peanut butter has as many calories as (and more sugar than( the regular. Or that you typically fill your bowl with not one, but TWO 200-calorie servings of cereal. Or that you would never touch Wonder bread but can't resist a crusty (white flour) baguette.

Salt Strikes Swiftly

A high-salt meal can stiffen your arteries within 30 minutes. Arteries that lose their ability to expand when they need to can increase the risk of high blood pressure, heart attack, stroke, and cognitive decline.On two separate occasions, researchers fed 16 healthy men and women with normal blood pressure a meal that contained either 115 milligrams of sodiem or 1,495 mg ( a full day's worth). At 30 minutes and 60 minutes after the high-sal meal, the ability of the participants' arteries to expand was more impaired than it was after the low-salt meal.
