Aspartame, artificial sweetener, decreases fat deposits in mice at a cost of mild cardiac hypertrophy and reduced cognitive performance. Long-term exposure to artificial sweeteners may have detrimental impact on organ function even at low doses (~ to one-sixth recommended max human daily intake).

High-fat diets are a major risk factor for liver cancer. New research shows that excess fat rewires liver cells, pushing mature hepatocytes into a stem-like state. This helps them survive metabolic stress, but over time increases their likelihood of becoming cancerous.
