More on Fasting during Ramadan, Practicing and Potential Dehydration During Football Season

An article that came out in today’s Salt Lake Tribune looks at some young athletes who have observed Ramadan even during football season by not eating or drinking from sunrise to sunset. In the article one young player discusses some of the challenges he experienced when not eating and not drinking water during the day and still practicing football.

I had mentioned Ramadan as an example in the Introduction to Nutrition Lecture this week that people’s religious beliefs can impact their eating habits, or in this case their lack of eating habits.

My biggest concern here is the not drinking. Not drinking water during especially hot athletic practices, could potentially lead to dehydration. You can read more about preventing dehydration in children (or adults) in the two articles that I wrote on this topic, Preventing Dehydration and Heat-Related Problems in Children and Tips for Preventing Your Child from Getting Dehydrated in the Heat.

More about Ramadan

Ramadan Crescent MoonRamadan, the annual 30-day Islamic holiday during which all believers abstain from food, drink and physical pleasures such as smoking and sex from dawn until sunset.

According to the article not everyone has to fast during Ramadan. Pregnant or menstruating women are exempt but expected to make up the lost fast days during the course of the year. Children begin fasting gradually, first half a day, then several days, until they grow old enough to fast without injuring their health.

The practice is meant to instill discipline, and to encourage gratitude and identification with the poor.

New Study Finds Toxins in Some Herbal Medicines

Herbal SupplementsA new study published this August in JAMA found that one-fifth of both US-manufactured and Indian-manufactured Ayurvedic medicines purchased via the Internet contain detectable lead, mercury, or arsenic.

The purpose of the JAMA (Journal of the American Medical Association) study was to “determine the prevalence of Ayurvedic medicines available via the Internet containing detectable lead, mercury or arsenic.” The study was also designed to compare the prevalence of toxic metals in US- vs Indian-manufactured medicines and between rasa shastra and non–rasa shastra medicines.

Lead, mercury, and arsenic have been detected in a substantial proportion of Indian-manufactured traditional Ayurvedic medicines. These metals may be present due to the practice of rasa shastra which is to combine herbs with metals, minerals, and gems.

More about Arsenic, Lead and Mercury
According to the study research more than 80 people have developed lead poisoning worldwide from Ayurvedic medicines since 1978. Lead and mercury can damage the kidneys and brain, especially in children. Arsenic can cause cancer.

Ayurvedic medications are largely used by adults to treat problems ranging from indigestion to infertility. About 4% of the 193 products that author Robert Saper of the Boston University School of Medicine and Boston Medical Center tested were labeled for use in children. Among the metal-containing products, 95% were sold by US Web sites and 75% claimed Good Manufacturing Practices.

The bottom line, since 20% of both US-manufactured and Indian-manufactured Ayurvedic medicines purchased via the Internet contained detectable lead, mercury, or arsenic one should be extremely cautious when using these products.

Parents Influence Whether Their Children Eat Fruits and Vegetables

Mom and ChildParents are one of the greatest influences on their children’s eating habits. This has been confirmed in a new study published this summer.

According to researchers at Washington University in St. Louis parents who providing fruits for snacks and serving vegetables at dinner can shape a preschooler’s eating patterns for his or her lifetime.

Researcher Debra Haire-Joshu, Ph.D., a professor at the George Warren Brown School of Social Work found when parents eat more fruits and vegetables, so do their children. On the other hand, when parents eat and give their children high fat snacks or soft drinks, children learn these eating patterns instead.

I firmly believe if we teach our children how to make healthy choices, about good health, nutrition and being active; these will help them to develop healthy habits and lifestyle choices to they can be healthy for a lifetime.

New Olympian Michael Phelps Now a Junk Food Spokesperson?

People are wondering what kind of a role model Michael Phelps is going to be to the growing population of overweight and obese children. His choices of foods to sponsor and endorse caused many child obesity experts to denounce his endorsements.

Kellogg Co. announced on August 19 that Michael Phelps, winner of eight gold medals at the Beijing Olympics, will be featured on upcoming boxes of Kellogg’s Frosted Flakes and Kellogg’s Corn Flakes. No longer is Wheaties the breakfast of champions in stead it’s Tony the Tiger’s GREEAATTT cereal.

Phelps has also been serving as ambassador for a program sponsored by McDonald’s to bring Chinese children to the Olympics and serve them American fast food. Consumer Health advocate Mike Adams, offered these words on the questionable choices being made in endorsing these products:

Olympian Michael Phelps is currently an active participant in this “junk food imperialism” that’s sweeping through China, ensnaring hundreds of millions of children in a junk food diet that may doom many of them to deadly diseases later in life.

The Children’s International Obesity Foundation (CIOF) believes that celebrities should think twice before choosing to endorse or encourage the consumption of any product which is inherently unhealthful to children, especially if that product is correlated to obesity, diabetes, and a myriad of dangerous conditions.”

Douglas Castle, Senior Adviser to CIOF has pointed out that

“Public figures like Michael Phelps exert a major influence over our youngsters. Mr. Phelps is a superior athlete by any measure, but his judgment regarding the McDonald’s and Kellogg’s Frosted Flakes endorsements was either ill-advised by his handlers; the irrational product of too much blood sugar; or a sad triumph of greed over good.”

Let’s hope that the public outcry will cause them to reconsider or at least the parents of the children being targeted to reconsider supporting the endorsed products.

Truth in Advertising: The Airborne Case

The Airborne company has fined $30 million by the Federal Trade Commission for false advertising, namely claiming Airborne can help reduce the length of a common cold. The makers of Airborne tablets have agreed to pay $30 million to settle the lawsuit.

What is Airborne?

According to the Airborne Company’s website:

Airborne Immune Boosting FormulaAirborne is a dietary supplement that was created by a school teacher. Airborne is a proprietary combination of 17 vitamins, minerals and herbs.

The key ingredients in Airborne have been shown to help support a healthy immune system as shown in scientific studies and medical journals.

Airborne was created by Victoria Knight-McDowell, a second-grade teacher who got tired of catching colds from her students.

She started selling the product in 1997, three after Congress voted to allow dietary supplement makers to claim their products have an effect on a body structure or function, such as the immune system. Claiming to cure or treat illnesses requires FDA approval.

No Tangible Evidence to Support the Claims

Lydia Parnes, director of the Federal Trade Commission’s Bureau of Consumer Protection said that “There is no credible evidence that Airborne products . . . will reduce the severity or duration of colds, or provide any tangible benefit for people who are exposed to germs in crowded places.”

Consumers who bought Airborne products between 2001 and 2008 have until Sept. 15 to apply for a refund for as many as six purchases, the FTC said. Claims will be paid by Oct. 15, 2008.

The FTC action adds $6.5 million to a previous class action settlement in which Airborne agreed to pay $23.5 million in customer refunds and attorney fees.

When I looked for Airborne on Amazon, the ‘Immune Boosting’ formulas were listed as being currently unavailable, but they had a whole host of other options, including a formula for children.
