What the study found

Points to benefit

Blood fat responses differed only a little between meals. Grain beef and lamb gave a lower blood triglyceride rise than the plant burger (grain: -0.346; 95% CI: -0.692, -0.0004).

How much this study counts

  • ✓Randomized: people were put into groups by chance, so the groups start out alike.
  • –Small: 27 people. Small trials can miss real effects or find chance ones.
  • –Measured lab tests or markers, which stand in for cancer, heart disease and death. A better marker does not always mean better health.
  • –Company stake: Some authors received support from the Meat Industry Association.
  • •Summarized from the PubMed abstract only. The full paper may hold details the abstract leaves out.

✓ Strength– Limit• Note

These points come from fixed rules about the type of study, its size and length, what it measured, and who has a stake. Every study on Digestery gets the same rules.
