In May, the World Health Organization issued an alarming report that declared widely used non-sugar sweeteners like aspartame are likely ineffective for weight loss, and long term consumption may increase the risk of diabetes, cardiovascular diseases and mortality in adults. A few months later, WHO declared aspartame, a key ingredient in Diet Coke, to be a "possible carcinogen", then quickly issued a third report that seemed to contradict its previous findings " people could continue consuming the product at levels determined to be safe decades ago. That contradiction stems from beverage industry corruption of the review process by consultants tied to an alleged Coca-Cola front group, the public health advocacy group US Right to Know said in a recent report. It uncovered eight WHO panelists involved with assessing safe levels of aspartame consumption who are beverage industry consultants who currently or previously worked with the alleged Coke front group, International Life Sciences Institute (Ilsi). Aspartame was first approved for use in the US in the early 1980s over the objection of some researchers who warned of potential health risks. In recent years, as evidence of health threats has mounted, industry has ramped up a PR campaign to downplay the issues. Ilsi representatives have sought to shape food policy worldwide. [Gary Ruskin, US Right to Know's executive director], characterized the aspartame controversy as a "masterpiece in how Ilsi worms its way into these regulatory processes".
