The World Health Organisation (WHO) has reacted to a news report that talks about artificial sweeteners, especially aspartame, and their link to possible increased cancer risk. Speaking to NDTV, WHO said that one of its key committees has assessed the potential carcinogenic effect of aspartame and "will update its risk assessment exercise". A Reuters report had said that WHO's International Agency for Research on Cancer (IARC) will hold a meeting in July where popular sweetener aspartame will be listed as "possibly carcinogenic to humans" for the first time.
