Is There a Link Between Diet Soda and Cancer?

Many people have questions surrounding aspartame, especially when it comes to diet soda and whether it is cancer-causing. Aspartame, sold under the names NutraSweet® and Equal®, has been used in the U.S. since the 1980s and is one of the most common artificial sweeteners found in prepared foods and beverages.
There has not been conclusive evidence that aspartame consumption is directly associated with an increased cancer risk. The FDA has set an acceptable daily intake (ADI), for which it considers safe for consumption for all sweeteners on the market.
The FDA ADI for aspartame has been set at 50 mg/kg (1kg = 2.2lb) of body weight. For example, the ADI level for an individual weighing 68 kg (or 150 pounds) would be 3400 mg of aspartame. An average 12-ounce can of diet soda contains 180 mg of aspartame. Therefore, the ADI level established by the FDA would allow for that individual to safely drink up to 19 cans of diet soda per day. It is unlikely most people would drink that much diet soda, so it is safe to say most diet soda drinkers consume well below their ADIs for aspartame.
Overall, individuals do not need to use sugar substitutes in their diets. If you are trying to reduce your sugar intake or lose weight, start with reducing your sugary food and beverage portion sizes. However, sugar substitutes can be a helpful alternative to sugary foods and beverages, if used in moderation.
