How do you find reliable health information online?

HPRC Fitness Arena:
Searching the internet for reliable health information.

Despite widespread access to internet-based healthcare information, there’s almost a complete lack of evidence showing any effects all this information may have on health outcomes. According to a study published in Health Expectations, this indicates that there’s a disparity between the health information we find online and our ability to use it properly.

So, with as much information as there is on the internet, how can we, as consumers, find reputable sources for our health questions? The internet can be a great resource when you want to learn about a specific disease or health condition. You can also find tips on staying healthy. But among the millions of websites that offer health-related information, many present myths and half-truths as if they are facts.

To avoid unreliable health information when you’re surfing the internet, use these tips to find reliable information:

  1. Keep in mind that anyone can publish anything they want on the internet, regardless of the facts. Ultimately, it’s up to the consumer to determine which information source is credible.
  2. In order to determine a trusted, verified source for credible and objective information, stick with well-respected health websites. A good starting point is healthfinder.gov, which provides a “Health A to Z” topic listing (http://www.healthfinder.gov/HealthAtoZ/ ) of over 1,600 health topics from the most trusted sources.
  3. Newspapers always use more than one source for verifying factual information. The same should hold true for health information. When searching a topic, it’s important to find at least a second reference to confirm your findings. Find a third reference, too, if possible. When several sources report similar information on a topic, it’s more likely to be accurate and up-to-date. In general, if you can't find the information duplicated in more than two or three references, then the information is questionable at best.
  4. Become skilled at separating facts from opinions. This can sometimes be difficult, as the evidence that exists may be minimal. It's important that you know the difference between fact and opinion, especially when you're researching treatment alternatives.
  5. Testimonials and personal stories tend to focus on a patient’s subjective point of view. If you find a website that quotes patients about the effectiveness of a treatment or therapy, this information is biased and cannot be trusted as a reliable source. However, there is information to be learned from the experiences of patients by using other sources (for example, through blogs and wikis, and support group message board forums). In those situations, refer back to point 1 (above) as your first line of review.
  6. Make sure the information you find is the most current available. Often, you will find that research and studies conflict with one another, or that newer information trumps older information.

Finally, information that you find on a website does not replace your doctor's advice. Your doctor is the best person to answer questions about your personal health. If you read something on the internet that doesn't concur with what your doctor has told you, make a point to speak with him or her about it.

Study examines energy drinks claims on athletic performance

HPRC Fitness Arena:
Popular energy drinks promise superior athletic performance and weight loss but do the claims hold up?

Popular energy drinks promise superior athletic performance and weight loss but do the claims hold up? Not always, according to a study conducted by researchers from Nova Southeastern University.   According to the study, energy drinks may increase athletic performance and aerobic benefits. The researchers found conflicting evidence regarding the impact of energy drinks on weight loss, although some data suggest that combining energy drink use with exercise may enhance body fat reduction.

Family influence: Eat more fruits and vegetables!

HPRC Fitness Arena:
Setting an example by eating our veggies.

A recent study published in the Journal of Nutrition Education and Behavior found that  4th and 5th grade students ate more fruits and vegetables if they helped their family shop for them, and if their parent(s) ate fruits and vegetables the day before. The bottom line: eating fruits and vegetables helps us, and the children around us, be healthier.

New report on protein drinks

HPRC Fitness Arena:
Consumer Reports says many protein drinks contain contaminants.

Recent surveys of dietary supplement use indicate that about 20 percent of active duty personnel are using some type of protein powder. The percentage of users is likely higher among special operations personnel, and this is of concern given the July 2010 Consumer Reports® Alert on protein drinks. These powder products are typically mixed with milk, water, or another liquid to make a shake and promoted as a sure way to increase muscle mass. The products often come in different flavors, with strawberry and chocolate the mainstays.

The Consumer Reports® Alert indicated that most of the 15 protein drink products analyzed contained miniscule to concerning amounts of selected contaminants – arsenic, cadmium, lead, and/or mercury – each of which is toxic to various organs in the body. Military personnel commonly use several of the products noted in the report. These include EAS Myoplex Original Rich Dark Chocolate Shakes; Muscle Milk chocolate, vanilla crème, and nutritional shake beverages; MuscleTech Nitro-Tech Hardcore Pro-Series Vanilla Milkshake; selected GNC products, and BSN and Optimum Nutrition whey protein products.

It is important to note that if three servings of these products were taken per day, consumers could be ingesting amounts of these contaminants in excess of the maximum limits proposed by the United States Pharmacopeia, the authoritative standard for health products. Importantly, toxic effects have been reported from using these products and are of concern because the Food and Drug Administration does not require such products to be tested to confirm the absence of contaminants and other potentially dangerous products before they are sold.

Take Home Message: A chicken breast, three 8-oz glasses of milk, and three eggs are inexpensive sources of high quality protein, whereas protein powders are expensive sources of uncertain quality, and potentially contaminated, protein. It is both better and cheaper to eat real foods.

Antioxidant supplementation for performance enhancement?

HPRC Fitness Arena:
Should you take antioxidants after endurance training?

Recent research suggests that antioxidant (vitamins A and E) supplementation has no effect on exercise performance after strenuous endurance training in individuals without vitamin deficiencies. Instead of taking antioxidant supplements to enhance performance, it’s more beneficial to eat a balanced diet with lots of fruits and vegetables.

Eating as a family in childhood leads to positive health behaviors in adolescence

HPRC Fitness Arena:
A study published in the Journal of Health Psychology found that the more often a family eats together in childhood, the more likely an adolescent is to exhibit effective coping skills, good communication skills AND the less likely they are to smoke and feel high levels of stress in late adolescence.

A study published in the Journal of Health Psychology examined females age 9-19 and found that the more often a family eats together in childhood (i.e. before age 12), the more likely the adolescent is to exhibit effective coping skills, good communication skills AND the less likely they are to smoke and feel high levels of stress in late adolescence. For the full study, see Franko, D., Thompson, D., Affenito, S., Barton, B., & Striegel-Moore, R. (2008).

Diet: Major piece of soldier's health, fitness puzzle

HPRC Fitness Arena:
As Army Chief of Staff Gen. George W. Casey Jr. stresses the Comprehensive Soldier Fitness Program, the U.S. Army Sergeants Major Academy finds itself at the tip of the spear in offering health and fitness insight to its enlisted members.

By G. A. Volb | Army News Service

May 24, 2010

As Army Chief of Staff Gen. George W. Casey Jr. stresses the Comprehensive Soldier Fitness Program, the U.S. Army Sergeants Major Academy finds itself at the tip of the spear in offering health and fitness insight to its enlisted members.

Senior Army leadership not only wants a broadly-skilled NCO treading the battlefields of tomorrow, but one that is both physically and spiritually fit. The former is a product of fitness regimens designed to enhance Soldier's ability to withstand the stresses and challenges of today's real - world operations tempo – and diet, not surprisingly, is a major piece to the puzzle.

Dietician Mrs. Jennifer Eiland, left, discusses possible changes Master Sgt. Anthony Jones may want to consider regarding his diet to help better his overall fitness. Jones, a Philadelphia, Pa., native lost nine pounds in just over a month following his initial meetings with Eiland. "I just used a few common sense diet and lifestyle changes that Jennifer suggested," the 44-year-old Jones said. (Photo Credit: G.A. Volb)"The food choices you make and when you eat have a direct impact on your energy level, ability to concentrate, overall feeling of well-being and gut function," said Jennifer Eiland, a dietician and part of the Army Physical Fitness Research Institute's staff at their USASMA annex. "It also affects your ability to complete an exercise session."

Casey, it should be noted, is so big on Soldier fitness that he's made the CSF Program, established in 2009, a priority as the Army tries to focus on the five dimensions of strength: Physical, Emotional, Social, Spiritual and Family.

The general's intent is to increase the strength, resilience and enhance performance of all Soldiers, family members, and Department of the Army civilians. None of it is possible if the old quip, "You are what you eat" makes sense and everyone is shoveling junk food down their necks.

"Diet is extremely important to realizing health and fitness goals," said the 25-year dietitian from Roy, Utah. "It influences almost three-quarters of the results of our health assessments. It can also influence a person's aerobic capacity; heavier participants typically have lower V02 or lung efficiency as a result. Mood and alertness are also affected by diet."

She stressed that eating a diet full of sugar, salt and fat lowers one's energy level and ability to concentrate, which in turn, can negatively affect school work and a Soldier's performance.

"It affects chronic disease risk on a number of levels as well," she offered. "Obesity increases the odds of contracting cancer, diabetes, heart disease and high blood pressure. Excessive sodium intake can increase blood pressure in over two-thirds of the population and risk of stroke and heart attacks according to the latest from the American Heart Association and Centers for Disease Control."

In a recent letter to the troops, Sgt. Maj. of the Army Kenneth Preston emphasized the need for Soldiers to work on all five areas stressed by the CSF Program; most of which can be affected by diet.

"We want CSF activities to become a part of our daily lives, just as we do physical training every day to build and strengthen the physical dimensions of CSF," said Preston in his letter. "We want the members of our team to do more than just cope with adversity; we want them to grow from their life experiences."

"Reflecting on the past eight years of war and our deployment experience in Afghanistan and Iraq, we can now begin to understand the individual health and resilience problems associated with our deployment tempo," he said.

An unhealthy Soldier is less effective," said Eiland. "A sergeant major's overall health, including how he or she eats, influences their ability as leaders ... and the influence they have on the health choices of their young Soldiers."

Eiland pointed out that a prominent group of retired military leaders want junk food taken out of America's schools because the obesity epidemic, especially in young people, is limiting the number of people who can be recruited into the military, making obesity a national security issue.

On a positive note, she added that many Soldiers have a sincere interest in improving their eating habits.

"A good majority tend to eat more meat and fewer fruits and vegetables than is considered optimal for good health," said Eiland. "Including more whole grains and less processed foods is also an area I frequently discuss with Soldiers. Sugary beverages seem to be a favorite as is eating fast food and microwave meals given their busy schedules. However, if dietary changes are presented in a practical and doable way to them, most will make changes."

The major challenges, according to the dietitian, are getting organized and planning ahead.

"Enlisting uncooperative family members, finding time to cook their own meals and changing an old mindset are also challenges," she said.
