Once in a while the FDA catches deceitful claims made by food manufactures.  But for every slap on the hand by the FDA, dozens of other product makers use sleight of hand techniques and carefully constructed language to lead consumers to a single conclusion: this product is magic!  Caveat emptor.  
Or do you have a sense that a love relationship was established between the FDA and the pharmaceutical industry, which forged the agency’s rule that no food maker can claim similar effects claimed by big-business drug companies?
I’m just saying.
