Does aspartame cause cancer? | Nutritionist Explains | Myprotein

Does aspartame cause cancer? You may have seen headlines claiming aspartame was classified as a possible carcinogen, but that classification sounds much scarier without the proper context. In this YouTube Short, expert nutritionist Dr Richie Kirwan explains why the International Agency for Research on Cancer (IARC) classified aspartame as Group 2B, possibly carcinogenic to humans, and what that actually means for people consuming artificial sweeteners. Key Facts: IARC classified aspartame as Group 2B, meaning “possibly carcinogenic to humans.” Group 2B means there is limited evidence of carcinogenicity in humans. It does not mean aspartame has been proven to cause cancer. IARC classifications identify potential cancer hazards rather than estimating the level of risk from a typical amount of exposure. Other very different exposures have historically appeared in Group 2B, demonstrating why the category alone doesn't tell you how dangerous something is. Following the IARC assessment, the WHO/FAO expert committee JECFA maintained the acceptable daily intake for aspartame at 0–40 mg per kg of body weight per day. The dose and amount you're actually exposed to are essential when interpreting health risks. FAQ: Q: Did IARC say aspartame causes cancer? A: No. IARC classified aspartame as “possibly carcinogenic to humans,” reflecting limited evidence rather than proof that normal consumption causes cancer.
