Health Halo: Supports Immunity
The Facts: In order for food companies to claim that their product can help prevent a specific disease, they must submit scientific evidence to the FDA which can take up to 540 days to get approved. However, an increasing number of manufacturers are using language that falls outside the law, essentially allowing them to make unsubstantiated health claims, according to the Center for Science in the Public Interest. For instance, companies cannot say that a nutrient in their product "helps reduce the risk of cold and flu" without FDA approval. They can, however, say it "supports immunity."
Shop Smart: No single food product is going to ward off a specific illness. That’s not to say some of the foods making these claims are unhealthy-but as with any other packaged food, you need to read the nutrition facts label. In the end you’ll do best by your body by sticking to a wholesome diet, low in sugar, fat, salt and artificial ingredients.
