I agree, but disagree. Aspartame is not a real cancer risk, but neither is red meat. Red meat is technical 2A with Aspartame 2B, but both have shown no signs of causality.

Similarly, zero cancer deaths have ever been attributed to red meat (~34,000 have been attributed to processed meat).

Red meat's fine in moderation. Aspartame is fine in moderation. NOTHING is fine in excess.
