HPRC Fitness Arena: Dietary Supplements
Godi International, Corp., located in South Florida is announcing a recall of Fruta Planta weight loss dietary supplements because the products contain Sibutramine an undeclared drug ingredient.

A recent systematic review found that nutritional and herbal supplements may be an effective way to treat anxiety and anxiety related problems without serious side effects. Although scientists reported that positive outcomes may be due to a placebo effect*, based on the review, there is scientific evidence to support the use of certain nutritional and herbal supplements to treat these conditions. If you are currently being treated for anxiety, discuss with your physical the option of using or including a natural supplement.
* A placebo effect is the beneficial effect in a patient following a particular treatment that arises from the patient's expectations concerning the treatment rather than from the treatment itself.
The Montreal Gazette is reporting that a new study made public yesterday links glucosamine, a popular over-the-counter dietary supplement for joint problems with a risk of developing diabetes. The study, which was published in the Journal of Endocrinology, looks at in-vitro cell lines from mice and rats.
The experiment showed that the supplement triggers a mechanism intended to lower high blood sugar levels, but it also destroyed about 50 per cent of the cells by affecting SIRT1, a protein crucial to cell survival.

The Federal Trade Commission (FTC) recently filed a complaint against POM Wonderful products due to deceptive advertising. POM Wonderful has claimed that its products will reduce (or treat) heart disease, prostate cancer and erectile dysfunction. The FTC says that these claims are not supported by scientific research.
So, what’s a health claim and what’s considered acceptable advertising as such?
A health claim statement has to have a food substance, food, or dietary ingredient, and a health condition or disease. The Food and Drug Administration (FDA) has approved certain health claims that, based on scientific evidence, show a link between a food or supplement and a health condition or disease. Health claims cannot state that a food product or supplement can treat or cure a disease. It may claim to minimize a disease risk; for example, a product advertised as low sodium can state the approved claim that “diets low in sodium may reduce the risk of high blood pressure, a disease associated with many factors.”
Health claims shouldn’t be confused with structure/function claims. These claims do not have to be approved and reviewed by the FDA, yet they must be truthful in stating that a substance maintains structures and/or functions of the body. We see these claims on many fiber-rich products, like “fiber maintains bowel regularity,” or a dairy product stating that “calcium builds strong bones.” Unlike health claims, structure/function claims cannot be linked to a health-related condition or disease. Also, an important point to keep in mind: if a dietary supplement label makes a structure/function claim, it must also state this disclaimer: “This statement has not been evaluated by the FDA. This product is not intended to diagnose, treat, cure, or prevent any disease.”
There are also nutrient content claims. These describe the amount of a nutrient in a product. Descriptions such as free, low, high, and rich in are used, or other terms that describe the nutrient content to that of the content in another product, such as reduced, lite, less, or more.
Manufacturing companies want consumers to buy their products. We, as consumers, must be savvy as we try to choose products that are healthy for our families and us. False health claims are used on food products as well as dietary supplements. They claim to help us lose weight, cure diseases, and prevent memory loss. The FDA has not approved claims that focus on the treatment of diseases. They have, however, set forth regulations to authorize health claims after the scientific evidence has been presented and reviewed.
Protein powder supplements are a popular source for packing on muscle. The September 27, 2010 edition Health section of the L.A. Times contains an article that poses the question of how much supplements, if any, should one use in building muscle mass?
The September 27, 2010 edition of the Wall Street Journal 's Health Blog reports that food giant Nestle' is looking to expand their stake in "functional foods" - foods that might prevent diseases. According to the article, the company is investing over $500 million into research in order to get a foothold into the functional food market. This move comes on the heels of yesterdays news that the Foot Trade Commission (FTC) is suing the maker of a popular pomegranate fruit drink, POM Wonderful LLC, in a widening effort by the government to clamp down on food ads that tout specific health benefits.
It remains to be seen how this will play out.
According to the press release, Nestlé will create a wholly owned subsidiary, Nestlé Health Science, as well as a research body, the Nestlé Institute of Health Sciences, “to pioneer a new industry between food and pharma,” the company said in a statement.
