WHEN Dr. Morando Soffritti, a cancer researcher in Bologna, Italy, saw the results of his team’s seven-year study on aspartame, he knew he was about to be injected into a bitter controversy over this sweetener, one of the most contentiously debated substances ever added to foods and beverages.

Aspartame is sold under the brand names Nutra-Sweet and Equal and is found in such popular products as Diet Coke, Diet Pepsi, Diet Snapple and Sugar Free Kool-Aid. Hundreds of millions of people consume it worldwide. And Dr. Soffritti’s study concluded that aspartame may cause the dreaded “c” word: cancer.

The research found that the sweetener was associated with unusually high rates of lymphomas, leukemias and other cancers in rats that had been given doses of it starting at what would be equivalent to four to five 20-ounce bottles of diet soda a day for a 150-pound person. The study, which involved 1,900 laboratory rats and cost $1 million, was conducted at the European Ramazzini Foundation of Oncology and Environmental Sciences, a nonprofit organization that studies cancer-causing substances; Dr. Soffritti is its scientific director.

The findings, first released last July, prompted a flurry of criticism from the Calorie Control Council, a trade group for makers of artificial sweeteners that has spent the last 25 years trying to quell fears about aspartame. It said Dr. Soffritti’s study flew in the face of four earlier cancer studies that aspartame’s creator, G. D. Searle & Company, had underwritten and used to persuade the Food and Drug Administration to approve it for human consumption. “Aspartame has been safely consumed for more than a quarter of a century and is one of the most thoroughly studied food additives,” read one news release from the council.
