Stephen Voltz (left) and Fritz Grobe create a geyser effect from a combination ofdiet soda and Mentos mints.

WASHINGTON - Nerv research suggests that diet soft drinks may actually contribute to rveight gain. Now, an advocacy group is charging Coca- and PepsiCo with engaging in false advertising.

The California-based group is known as Right to Know. It plans to file two citizen petitions Thursday. The petitions call on the Food and Drug Administration (FDA) and the Federal Trade Commission (FTC) to stop the companies from branding artificially sweetened products with the rvord "diet." "Consumers are using products - and Diet - that are advertised to make us think they assist in weight loss," says the petition to the Food and Drug Administration. "In fact ample scientific evidence suggests that this is not true, and the opposite may rvell be true." Soda Makers Disagree With Claims The American Beverage Association speaks on behalf of Coca-Cola and PepsiCo. It strongly challenged the petitions' claims. The association pointed to numerous studies showing "that diet beverages are an effective tool as part ofan overall rveight management plan."

The petitions call for more questioning about the marketing of products that contain any artificial srveeteners. The most popular , , is used in more than 5,ooo products.

Both Diet Coke and contain aspartame. The artificial srveetener has been mainly sold under the brand name NutraSrveet and is consumed worldw'ide. Last year, Diet Coke ranked third and Diet Pepsi rvas seventh in U.S. carbonated soft-drink sales.

There have been safety controversies around the use ofa number of artificial sweeteners for decades, especially NutraSrveet and . Horvever, Right to Knorv is the first group to call for investigations into possible deceptive marketing. Some Studies Say Diet Drinks Increase Weight Gain

A number of recent studies have challenged the beliefthat artificial srveeteners help rvith rveight loss.

For example, a tw'o-year study of 164 children found that overweight kids drank more diet sodas than normal-weight children.

Another nationrvide study looked at more than ro,ooo children ages 9 to 14. It found that, for boys, drinking diet soda was "significantly associated with weight gains."

A zoto review ofprevious studies concluded that "artificial sweeteners may contribute to rveight gain." Another zoro revierv also found "an association between artificially srveetened beverage consumption and rveight gain in children."

Also of particular interest is an Israeli study published last fall in the journal Nature. It found that mice given the three most popular sweeteners developed bacterial changes in their guts that caused glucose intolerance. In humans, this raises the risk of .

The researchers at the Weizmann Institute of Science in Rehovot, Israel, found similar effects. Their study observed this among people who ate artificially sweetened foods for a week. Not All Scientists Agree However, not all scientists are convinced. In particular, they challenge the idea that the sweeteners can cause weight gain.

One such scientist is Dr. James O. Hill. who has conducted his orm studv of artificial sweeteners.

"I am absolutely convinced that there's no way they are causing rveight gain," Hill said. Drinking diet sodas is "not something people should worry about," he added.

Hill's orvn study found that people who drank diet soda lost more rveight than those rvho drank rvater. Hill acknowledged receiving hundreds of thousands of dollars from the American Beverage Association to finance the study. However, he said the industry group had no role in designing the study.

Right to Know acknowledges the conflicting research results in its petition. Horvever, it points to evidence that "industry-funded studies" are "less trustrvorthy than those funded independently." Petition Could Revive Old Controversy

Neither the Food and Drug Administration nor the Trade Commission would comment on the petitions. The Food and Drug Administration regulates food labeling, while the Trade Commission polices advertising claims.

Trade commission spokesman Peter Kaplan said the agency is dedicated to "combating deceptive advertising. "

"Deceptive health claims in particular are a priority ofthe agency," Kaplan said.

The petition to the FDA could bring the agency back to the days of bigger controversies: its decisions in the early r98os to approve the use of aspartame, first as an added ingredient in food and then in diet soft drinks.

There have been several research studies and books that link aspartame to health problems. These problems range from cancers to neurological ailments. Yet the FDA has stood by its position that the sweetener is safe, except for people rvho suffer from a rare disease knorvn as phenylketonuria, a developmental illness. Quiz
