Krafts Crystal Light Immunity Berry Pomegranate drink falsely claims that its vitamins A, C, and E will help maintain a healthy immune system, charges the Center for Science in the Public Interest.
The nonprofit nutrition and food safety watchdog group today urged the Food and Drug Administration to crack down on that and other deceptive structure/function claims increasingly appearing on food labels.
When companies claim their products will maintain a healthy immune system, consumers believe this means those products will help ward off disease. But while vitamins A, C, and E are important for the functioning of just about every system in the human body, theres little evidence to suggest that drinking Crystal Light will have any impact on the average persons immune system, the group said.
There is no consistent evidence that adding vitamin A to a food or drink is beneficial for the immune function of adults, and it might even worsen respiratory illnesses among children, according to researchers at the Harvard School of Public Health.
The Crystal Light drink has only 500 IU just a small fraction of what one would find in a typical multivitamin. (In fact, says CSPI, theres not much berry or pomegranate in this drink either; less than 2 percent of it is unspecified natural flavor, and the rest is water, artificial sweeteners, preservatives, and food dyes.)
Another Kraft product, Fruit2O Immunity Nutrient Enhanced Water Beverage, also bears a bogus help maintain a healthy immune system claim, CSPI said, also charging that its Berry Pomegranate flavor is just as bereft of berries and pomegranates as Crystal Light.
Food manufacturers know that they can get away with this kind of consumer deception because the Bush FDA is letting the industry play by many of the same loosely-goosey rules followed by dietary supplement manufacturers, says CSPI legal affairs director Bruce Silverglade. The result is that the deception that is commonplace on dietary supplement labels has now spread to the much larger food industry.
Silly claims
Even some foods that are perfectly healthy in their own right bags of frozen fruit or vegetables bear silly label claims touting magical immunity-boosting properties, CSPI said.
For instance, Green Giant Immunity Boost, a General Mills product, consists of frozen broccoli, carrots, pepper strips, and seasoning. While its a perfectly healthful food, there is no evidence to support the claim that the product supports a healthy immune system, or provides the promised immunity boost.
In an informal survey of 1,000 health-oriented consumers conducted by CSPI, 49 percent thought this product would help prevent colds and the flu.
Doles Wildly Nutritious Tropical Fruit frozen sliced pineapple, mango, kiwi fruit, papaya, and strawberries is another decent food. But the marketing copy on the label makes it sound like nothing short of a medical miracle, whose vitamins variously maintain, support, or even enhance white blood cell function and the cells lining the airway, urinary, and digestive tracts, and can protect the body against viruses and bacteria, CSPI said.
Sometimes a pineapple is just a pineapple, said CSPI senior nutritionist David Schardt. Consumers should eat their fruits and vegetables, by all means. But save your money by watching out for weasel words like support, maintain, or enhance, which often imply that a specific brand name food can prevent disease.
Express disease prevention claims on food labels must be approved by the FDA prior to marketing. But food companies do not need the FDAs permission to claim that various nutrients allegedly play in the normal structure or functioning of the body.
Thus, while the makers of Welchs Fiber 100% Grape Juice may not claim that that product with its added fiber cures chronic constipation or relieves irritable bowel syndrome, they can state that it support[s] a healthy digestive system. But in this case, the fiber comes from maltodextrin, not fruit, and theres no evidence that the amount of maltodextrin in the grape juice has any effect on digestion, Schardt said.
In a formal complaint filed today with the FDA, CSPI says the agency should stop the bogus claims and set new rules for food companies requiring them to base future claims on solid scientific evidence and make only FDA-approved claims.
'Brain food'
CSPIs complaint to the FDA also criticized claims that products supposedly help nourish your brain (Minute Maid Enhanced Juice Blend Omega-3 DHA Pomegranate Blueberry Flavored Blend of 5 Juices), keep your digestive system healthy (Sunsweet PlumSmart for Digestive Health Plum Juice Extra with Fiber), and protect cartilage and joints (Minute Maid Enhanced Juice Active 750 mg Glucosamine HCL).
Several prominent researchers with expertise in nutrition and immunity, David C. Nieman, John D. Potter, and Neli Ulrich, also today urged FDA to suspend its approval of immunity-related structure/function claims on food labels.
Many, if not most, consumers associate the immune system with protection from disease, the researchers wrote. There is little or no evidence that these products can provide that protection.
