Nutritional supplements are popular among Americans but people need to educate themselves and use caution when using these products to try to reduce their risk of cancer, says a University of Texas expert.

“Researchers are still unsure about whether or not minerals, herbs and other plants taken in pill, capsule, tablet or liquid form actually prevent cancer,” Sally Scroggs, health education manager at the Cancer Prevention Center at the University of Texas M.D. Anderson Medical Center, said in a news release from the center.

Vitamins E and C, for example, were found not to prevent cancer in the large-scale Women’s Health Study and the Physicians’ Health Study II. Findings from other studies suggest that some supplements may actually increase cancer risk by affecting the balance of nutrients in the body.

Blueberries and blackberries have high levels of antioxidants, which help the body deal with potentially dangerous cellular oxidation, but scientists say they’ve also found a cheaper source of antioxidants for consumers: black rice.

“Just a spoonful of black rice bran contains more health promoting anthocyanin antioxidants than are found in a spoonful of blueberries, but with less sugar and more fiber and vitamin E antioxidants,” study co-author Zhimin Xu said in a news release from the American Chemical Society.

“If berries are used to boost health, why not black rice and black rice bran?” suggested Xu, associate professor at the food science department at Louisiana State University Agricultural Center in Baton Rouge. “Black rice bran would be a unique and economical material to increase consumption of health-promoting antioxidants.”

The study authors noted that black rice bran could be used to boost the health benefits of breakfast cereals, cakes, cookies and other foods. It could also be added to beverages, and may serve as food coloring, allowing food manufacturers to avoid artificial colorants, the team said in the news release. The scientists explained that pigments in black rice bran extracts range from pink to black.

In the study, the researchers tested black rice bran grown in the Southern United States. Although brown rice is the most common rice variety produced worldwide, Xu said the study results suggest that black rice bran may be healthier than brown rice bran in terms of antioxidants.

In Asia, black rice is most commonly used for food decoration, such as in noodles or sushi. One variety of black rice is known as “Forbidden Rice” because in Ancient China, it was only permitted to be eaten by nobles and no one else, according to background information in the news release.

The study results were scheduled to be released Thursday at the national meeting of the American Chemical Society in Boston.

When you buy a bottled tea, you may not be getting the health boost you expect.

A new study finds that these increasingly popular beverages may contain far lower levels of antioxidants called polyphenols than green or black tea that you brew at home. In fact, some commercial tea beverages contain such small amounts of polyphenols that you would have to drink 20 bottles to get an amount equal to what’s in one cup of home-brewed tea.

Polyphenols are believed by scientists to have anti-cancer, anti-inflammatory and anti-diabetic properties.

“Consumers understand very well the concept of the health benefits from drinking tea or consuming other tea products,” researcher Shiming Li said in an American Chemical Society news release. “However, there is a huge gap between the perception that tea consumption is healthy and the actual amount of the healthful nutrients — polyphenols — found in bottled tea beverages. Our analysis of tea beverages found that the polyphenol content is extremely low.”

Li and colleagues measured the levels of polyphenols in six brands of bottled tea beverages purchased at supermarkets. Half of them contained virtually no antioxidants, while the polyphenol levels in others were so low that they would have little effect on health.

“Someone would have to drink bottle after bottle of these teas in some cases to receive health benefits. I was surprised at the low polyphenol content. I didn’t expect it to be at such a low level,” said Li, an analytical and natural product chemist at New Jersey-based biotechnology company WellGen Inc.

In fact, consumers buying commercially bottled teas may actually be spending money on substances detrimental to health, including sugar, high fructose corn syrup and sweeteners, Li said.

The study was presented Sunday at the American Chemical Society annual meeting in Boston.

Strep throat is a nasty infection, dubbed “strep” because it’s caused by streptococcus bacteria.

The American Academy of Family Physicians says common symptoms of strep throat include:

  • Having a fever.
  • Having swelling and pain in the glands that surround the neck.
  • Having swelling and redness of the tonsils.
  • Having visible white patches on the tonsils or in the throat.
  • Having a headache.
  • In children, having a rash or pain in the belly, or vomiting.


Straining the eyes while watching television or working on the computer can trigger a nasty headache. But so can your posture, stress and other factors.

To help determine if eye strain is the culprit, and if so, how to minimize it, the National Headache Foundation suggests:

  • Getting a complete eye exam, and taking care of any vision problems.
  • Using an anti-glare screen on your computer, or wearing tinted eyeglasses.
  • Sitting with proper posture when working at the computer or watching TV.
  • Taking frequent short breaks from the computer. Leave your desk for a couple of minutes and stretch your neck, arms and back.
  • Closing your eyes and breathing deeply while on a break.

Active LifestyleMost Americans know that being physically active is good for their health and helps them lose weight by burning calories.

Still, most American adults—up to 63 percent, according to some studies—don’t accumulate even an hour of moderate exercise in a week’s time.

One fitness and motivational trainer says he knows a way to motivate adults to get a move on and begin reaping the benefits of an active lifestyle.

“As children we rode bikes, played in the woods, or kicked a soccer ball around, not because we had to or someone told us to, but because we wanted to,” says Jay Snyder, a personal trainer in Springville, Utah. Snyder is certified by the American Council for Sports Medicine. “As adults, we still can tap into that spirit of play and be active because of the enjoyment it provides.”

As a busy person with family, work, and civic responsibilities, how can you find time for yet another activity?

“It’s essential to take a look at and address the circumstances of your life,” says Snyder. “If you’re a parent, for example, it’s easy to put yourself at the bottom of the list. But to nurture others, you have to nurture yourself and make your desire to swim or take a dance class as important as your child’s baseball practice.”

Heat cramps, heat exhaustion and potentially fatal heat stroke are risks when exercising or playing sports during the summer, but they can be prevented by taking a few simple precautions, advises a Medical College of Georgia expert.

Heat illness occurs when the body loses its ability to cool itself, Tim McLane, a certified athletic trainer at the MCGHealth Sports Medicine Center, said in a news release from MCGHealth. In normal conditions, the body uses sweat evaporation to cool itself during exercise. But hot, humid weather hinders sweat evaporation, which increases the risk of heat illness, he explained.

The neck has the vital task of supporting the head, but since it isn’t as protected as the rest of the spine, is it more susceptible to injury.

The American Academy of Orthopaedic Surgeons says possible causes of neck pain include:

  • An inflammatory condition, such as rheumatoid arthritis.
  • Degeneration of a cervical disk.
  • An injury stemming from an incident such as a traffic accident, sports injury or fall.
  • An infection or tumor affecting the neck, although this is rare.
  • A congenital abnormality of the vertebrae in the neck, which also is rare.


As Americans’ average weight keeps rising, their quality of life is falling, according to new research.

The nationwide study found that the number of healthy days per year that Americans lose due to obesity has more than doubled over the past two decades, from about 7.5 in 1993 to 17 in 2008.

Researchers calculated the amount of healthy time lost, in addition to noting trends of increasing obesity across the country in all racial and ethnic groups for men and women in every state.

While the findings support a general trend, some groups were more seriously affected. Obesity has caused black women to lose the greatest amount of time spent in good health (more than 24 fewer such days per year). That number is 31 percent higher than for black men, who lost the second highest amount of healthy time due to being obese, and 50 percent higher than that of whites.

Most of women’s healthy days lost to obesity were due to illness, while most of the men’s loss was due to early death, the study found.
