Better brain trauma testing urged for troops

WASHINGTON - A group of doctors and scientists said Thursday the U.S. needs to devise a uniform test for traumatic brain injury to be performed on all troops who are exposed to a blast or other violent event in wartime.

Traumatic brain injury, or TBI, is often referred to as the signature wound of the Iraq war. Roadside bombs, vehicle accidents and other events have left hundreds of thousands of troops with such an injury.

Most are mild, and military medical officials have said an overwhelming majority heal without treatment. But Brig. Gen. Loree Sutton, the head of the Defense Centers of Excellence for Psychological Health and Traumatic Brain Injury, has said 45,000 to 90,000 troops have suffered more severe and lasting symptoms.

The recommendations to Congress on Thursday came from a conference last fall in Paterson, N.J., sponsored by a congressional task force on brain injuries. Reps. Bill Pascrell Jr. of New Jersey and Todd Platts of Pennsylvania are chairmen of the task force.

The group suggested that the assessment tool be used in wartime to determine if a soldier should return to duty. It also recommended improvements to traumatic brain injury research, better access to care and more resources for families of troops with TBI.

It asked Congress to spend $350 million on its recommendations to be overseen by the Defense Centers of Excellence for Psychological Health and Traumatic Brain Injury.

"We're approaching this from every different angle possible," Pascrell said. "We have a sense of urgency."

Walkers should aim for 100 steps per minute

NEW YORK - People who walk for exercise should aim for a pace of 100 steps per minute to ensure their workout is intense enough, according to researchers.

Many people who want to keep fit use a pedometer to keep track of how many steps they take. However, the device gives no information on how intensely they're exercising — that is, whether their heart rate is being raised enough to improve physical fitness.

In the new study, researchers found that the average walker should aim for 100 steps per minute at a minimum in order to get a moderate-intensity workout.

Experts recommend that adults get at least 30 minutes of moderate activity, five times per week. If those 30 minutes are achieved in one session, that means taking a minimum of 3,000 steps per session. However, the researchers point out in the American Journal of Preventive Medicine, walkers can also break those steps down into several shorter exercise sessions throughout the day.

"Because health benefits can be achieved with bouts of exercise lasting at least 10 minutes, a useful starting point is to try and accumulate 1,000 steps in 10 minutes, before building up to 3,000 steps in 30 minutes," lead researcher Dr. Simon J. Marshall, of San Diego State University, said in a news release from the journal.

A simple pedometer and a wristwatch, he added, offer walkers a way to ensure they are working out intensely enough.

The findings are based on exercise tests given to 97 healthy adults with an average age of 32. In general, men needed to walk at a pace of 92 to 102 steps per minute to achieve a moderately intense workout for their hearts. The range for women was between 91 and 115 steps per minute.

"We believe that these data support a general recommendation of walking at more than 100 steps per minute on level terrain to meet the minimum of the moderate-intensity guideline," Marshall said.

Safe clicking tips when surfing for diet advice

With so many nutrition-related Web sites clamoring for your attention, sorting through the pile to find impartial and safe information can be frustrating enough to send you on a drive-thru binge.

Here are some basic tips for sussing out sites that are worth the click.

As a general rule, sites with the extensions .gov, .edu and sometimes .org contain accurate, unbiased information, says Jeanne Goldberg, a professor of nutrition science at Tufts' Friedman School of Nutrition.

But legitimate commercial sites — usually with .com endings — can be more user-friendly.

The trick with commercial sites is to look for a stamp of legitimacy, Goldberg says, such as an affiliation with a well-known organization, and to avoid being sucked into a sales gimmick.

The best sites for general health and nutrition offer multiple tools, such as calculators for calories, carbohydrates and body mass index, meal planning charts and comprehensive information on individual ingredients and products.

As with all research online, try to verify the source of the information. The most important thing is to look at the site's sponsor, says Gail Woodward-Lopez, associate director at the University of California-Berkeley's Center for Weight and Health.

For instance, food manufacturers or lobbying groups, which often use .org extensions, may have conflicts of interest, such as extolling the virtues of products, treatments or even other sites that they have a financial interest in. If the site belongs to an individual, be clear on the person's credentials.

Also, try to use sites that offer evidence for their advice, such as studies or footnotes that allow you to evaluate the source. And avoid sites that offer a "silver bullet."

"If they point to one very specific food as if it's the solution, or a specific vitamin or mineral, that's a red flag," Woodward-Lopez says. "If it's too much of a dream come true, it probably is a dream."

Some sites to consider:

This extensive food database offers at-your-fingertips information on carbs, calories, fat, protein, fiber and other elements of common foods, and does so in realistic and customizable portions. Includes generic foods, name brands and fast food options.

Also provides thorough explanations of food building blocks (what is protein, what does it do, how much do you need?). Like many commercial sites, it sells scales, blood pressure monitors and diet plans, but the pitch is unobtrusive and all the good information is free. Affiliated with Boston-based Joslin Diabetes Center, the world's largest diabetes research center.

Though aimed at diabetics, the site contains great nutritional information for anyone who cooks. Offers tips for cramming more healthy foods into your lifestyle. Best feature is My Food Advisor, which offers food suggestions based on the amount of carbs, calories or fiber you're after, and lets you calculate the nutritional value of meals you prepare.

The federal government's resource for general information on healthy eating and living. The best feature is a menu planner that creates a bar graph of your nutritional needs, based on body type and exercise habits. Also includes a fun space-themed game to teach children about making healthy choices.

Excellent source of general nutrition information. The site is somewhat heavy on fact sheets and tips from food manufacturers, but the information is good, the authors are clearly stated and each entry is vetted by ADA's review board.

Owned by CondeNet, the Web arm of Conde Nast Publications, this site is jammed with helpful calculators, including one that will do a nutritional analysis of your recipes. It even has search tools that help you find ingredients high or low in specific nutrients, such as low sugar or high fat.

8 Reasons Why Your Weight Loss Diet Can’t Help You

Dieting has become so popular that it’s estimated around 70 percent of the female population, and 30 percent of males have followed one at some stage.

The worrying thing is that many people don’t seem too concerned about whether the diet they choose is healthy or not - all that matters is losing a few pounds!

Although diets often produce results in the short term, unfortunately very few can maintain this weight loss for the months and years that are ahead.

Thus the yo-yo cycle of dieting continues, and it’s often to the detriment of your health long-term.

So, why don’t diets work?

#1 Diets are not designed to work!

If everyone could simply lose weight and keep it off, there would be no money in it for the diet companies.

In fact, most of their profit is made from repeat orders, for example in shakes, soups, and ready meals.

If you think about it, it’s really not in the interest of diet companies for you to lose weight and keep it off, is it?

I believe that many programs are actually designed to keep you fully dependant on their products for life. The consequence of stopping using their products is weight gain.

This is why following a ‘diet’, which teaches you about portion control, eating real food, and also looking at the emotional side of eating, is so important.

Anything short of this is bound to fail.

#2 Dieting is a short term fix

If you think of dieting as a short term thing, you are probably setting yourself up to fail.

This is because when you don’t plan for the future, you are really only thinking a couple of months ahead. So, when you lose a few pounds, you end up going back to your old eating habits, and gaining back the weight plus extra!

Think of it this way, if you are taking medication for high cholesterol, which is successfully lowering your cholesterol levels, by stopping taking this medication you would expect your cholesterol levels to begin increasing again, wouldn’t you?

A weight loss diet works in much the same way. When you stop following the plan, you begin gaining weight again.

While it is difficult, try to think of your diet as a new way of life.

For example, if you are currently drinking shakes for breakfast, lunch and dinner, can you keep this up for life? And if not, what is your plan of action when you stop taking them? Will you go back to your old way of eating? How will you prevent this from happening?

These are very important questions to ask yourself right now. I’d suggest jotting down some solutions to these questions as a way of beginning to plan for your future right now.

#3 Diets don’t encourage exercise

Many weight loss diets do not encourage both exercise and healthy eating as a whole package. However, if long-term weight loss success is what you’re after you need to realise that exercise and a healthy diet go hand in hand.

If your current diet promises you can, “Lose 10 pounds without any exercise!” be wary of it.

One of the problems with losing weight and not exercising is that you are losing muscle as well as fat. The more muscle you lose the slower your metabolism becomes, which will eventually make it even more difficult to lose weight.

Try to get in some exercise every day. Remember, it doesn’t have to be intense, but you should notice your heart rate increasing. Aim for at least 30 minutes, but preferably somewhere around 60 minutes every day.

#4 Diets don’t create lifestyle changes

If you want to achieve and maintain a healthy weight you need to work on making lifestyle changes that you can maintain for life, not simply a one off event.

Check out my free ebook, “The Lifestyle Makeover Guide” for more tips on doing this.

Focus on making small gradual changes in how you eat, for example stitching from one bottle of coke per day, to water. Or, swapping your afternoon chocolate cookie for an apple and some peanut butter.

Instead of learning all about the latest fad diet on the market, why not endeavour to learn as much as you can about controlling food portions? This is something that will be a huge help to you in the future.

It will also enable you to eat the foods you love, but in correct proportions, rather than eating a bunch of foods you just don’t even enjoy every day. Much more satisfying!

#5 Diets can slow your metabolism

Diets are often extremely restrictive in calorie intake, which can cause your metabolism to slow down.

This means you burn fewer calories each day. And, if you’re not exercising, you will also be losing lean muscle mass, which further slows your metabolism.

Make sure your calorie intake isn’t too restrictive. 1,200 calories per day is considered to be a very restrictive diet, and it won’t give you the nutrients and energy that you need for your body to stay healthy.

#6 Dieting makes you feel like a failure

Research shows that no matter what weight you are, dieting can make you hungry, and create powerful cravings for the very foods you are trying to avoid, such as sugar and fat.

Not only do these cravings lead to overeating, but it usually ends up causing feelings of guilt and failure.

Rather than viewing lapses as a sign that you’ve failed, you should think of them as inevitable. Now, this is not to say you go out of your way to eat the foods you are trying to avoid. However, you shouldn’t beat yourself up every time you overeat.

Telling yourself, “I’ve totally blown it again,” only serves to make you feel inadequate, and a victim in the yo-yo cycle.

A more balanced eating plan would allow you to have small amounts of your favourite foods, without the guilt factor, or the possibility of falling off the bandwagon every time you’re around unhealthy foods.

You must remember you are the one in control. So, take control of the situation, and don’t let food rule your life!

#7 Diets don’t help with your emotions

Do you eat to help you deal with emotional problems, rather than because you’re hungry?

Many people do, but a diet simply won’t help you with this. If anything, it can make you even more depressed, because it becomes one of the issues that cause overeating.

Check out my post on emotional eating and how to over come it.

#8 Dieting doesn’t change your core habits

If you are to lose weight and keep it off, you will have to make permanent changes to your eating and exercise habits.

It’s commendable to want to be a healthy weight and to manage your eating, but dieting as we know it, is not the way to do it.

For long-term weight loss, you will need to change your whole lifestyle. While this may sound completely daunting, trust me it is completely do-able.

In fact, you may even find it much easier than many of the diets you’ve been following throughout your lifetime.

So, what is a good diet?

A healthy diet for weight loss is balanced, nutritious, and enjoyable.

It will encourage you to:

  • Get five (or more) portions of fruit and veg each day
  • Eat fibre-rich foods
  • Reduce your intake of fat (especially saturated and trans fat)
  • Reduce your sugar and salt intake
  • Drink plenty of water
  • It doesn’t encourage excluding whole foods groups, such as carbs, meat or dairy
  • It doesn’t focus on single foods, such as cabbage soup, or meal replacement bars
