Robert Lustig on Artificial Sweeteners: warns against

Dr. Robert Lustig warns against artificial sweeteners. He covered them as a harm in his September 2026 interview alongside sugary drinks and ultra-processed food, grouping them with the products he says drive metabolic dysfunction.

His stated reasoning, consistent with his broader framework, is that sweetness without nutritional substance does not resolve the underlying dietary problem — the food supply remains broken regardless of whether the sweetener is sugar or a substitute. This is Lustig’s stated position, not an established safety finding.
