I get the feeling you’re being intentionally vague. Correct me if I’m wrong.
Are you hinting that they might not publish whatever their actual findings were, but rather a bias or perhaps a bought-and-paid-for party line or lobbyist agenda?

Aspartame | NutraSweet Company
In 1985, Monsanto Company bought G.D. Searle, and the aspartame business became a separate Monsanto subsidiary, the NutraSweet Company. In March 2000, Monsanto sold it to J.W. Childs Equity Partners II L.P. European use patents on aspartame expired starting in 1987, and the U.S. patent expired in 1992. Since then, the company has competed for market share with other manufacturers, including Ajinomoto, Merisant and the Holland Sweetener Company.
