contribution of dietary flavonoids to (...) antioxidant function in vivo is likely to be very small or negligible". But unlike controlled test tube conditions, in vivo anthocyanins have been shown to be poorly conserved (less than 5%), and most of what is absorbed exists as chemically modified metabolites destined for rapid excretion. A powdered preparation of freeze-dried açaí fruit pulp and skin was shown to contain cyanidin 3-O-glucoside and cyanidin 3-O-rutinoside as major anthocyanins (3.19 mg/g). The powdered preparation was also reported to contain twelve flavonoid-like compounds, including homoorientin, orientin, taxifolin deoxyhexose, isovitexin, scoparin, as well as proanthocyanidins (12.89 mg/g), and low levels of resveratrol (1.1 μg/g). Marketing In the 1980s, the Brazilian Gracie family marketed açaí as an energy drink or as crushed fruit served with granola and bananas; this demand led to the building of cottage industries and processing plants to pulp and freeze açaí for export. Scams In the early 2000s, numerous companies flooded the internet with açaí advertising, many of them with counterfeit testimonials and products. In 2009, açaí scams were ranked #1 on the US FTC's "scams and rip-offs" list, so that by 2011 sales of açaí flattened as the fad waned. Açaí was promoted heavily for its antioxidants, and many false claims were made, including a reversal of diabetes and other chronic illnesses, as well as expanding the size of the penis and increasing men's sexual virility. According to the Washington, D.C.-based Center for Science in the Public Interest thousands of consumers had trouble stopping recurrent charges on their credit cards when they canceled free trials of some açai-based products. In 2003, American celebrity doctor Nicholas Perricone included açaí berries among "superfoods", but such extravagant marketing claims regarding açaí as miracle cures for everything from obesity to attention-deficit disorder were challenged in subsequent studies. Even some websites purporting to warn about açai-related scams are themselves perpetrating scams. By 2011, Ralph Carson, the formulator of MonaVie, cautioned the public that the product was in fact nothing more than "expensive flavored water" and that any claims made about it were "purely hypothetical, unsubstantiated and, quite frankly, bogus". The FTC handed down an $80 million judgement in January 2012 against five companies that were marketing açaí berry supplements with fraudulent claims that their products promoted weight loss and prevented colon cancer. One company, Central Coast Nutraceuticals, was ordered to pay a $1.5 million settlement. Production Brazil is
