Why it scores 45

  2. Ultra-processed (NOVA 4, estimated): No NOVA group on file; estimated from 4 kinds of ultra-processing markers. Strong
  3. Erythritol: A 2023 study linked higher blood erythritol to cardiovascular events and found it increased clotting activity; long-term safety studies are warranted. Strong
