"Rethinking Policy Decisions: Addressing Substandard Metrics in Animal-Source Foods Reduction"

A perspective examines the use of substandard metrics in influential reports from the EAT-Lancet Commission and the Global Burden of Diseases (GBD) Risk Factors Collaborators, which advocate for significant reductions in animal-source foods in the human diet. Concerns are raised about the validity of assumptions, quality and transparency of input data, and appropriateness of statistical modeling in these reports. The reliance on global health estimates rather than primary data, along with questionable assumptions and statistical techniques, raises doubts about the accuracy and reliability of the recommendations for dietary shifts and their potential impact on human health.

"Revisiting the Hunter-Gatherer Narrative: New Research Reveals Surprising Insights"

Archaeological findings from burial sites in the Peruvian Andes dating back 9,000 to 6,500 years ago suggest that early human hunter-gatherers primarily consumed plants and vegetables, with wild potatoes and root vegetables being a dominant source of nutrition. This challenges the common belief of a high protein, meat-heavy diet and raises the possibility of a more gradual transition from foraging to farming. The study, published in PLOS One, indicates that plant foods comprised 80% of the individuals' diets, with meat playing a secondary role, contrary to the widespread assumption of meat dominance in early human diets.

Insights into the Diet of Young Tyrannosaurs: Fossilized Stomach Contents Reveal Prey Preferences

Paleontologists in Canada have discovered a 75-million-year-old fossilized skeleton of a juvenile tyrannosaurid dinosaur, Gorgosaurus libratus, with the remains of two young individuals of the small dinosaur Citipes elegans in its stomach. This finding provides direct evidence that young tyrannosaurs had different diets than their adult counterparts, suggesting a major dietary shift as they grew. Juvenile tyrannosaurs likely hunted small and young prey, while adults hunted large herbivores. The study sheds light on the ontogenetic dietary shifts of these iconic predators.

"Tyrannosaur's Last Meal: A Prehistoric Surprise Found in Stomach Fossil"

Scientists have discovered the remains of prey inside the stomach of a tyrannosaur skeleton for the first time, shedding light on the dietary habits and growth patterns of these mighty dinosaurs. The Gorgosaurus, a member of the tyrannosaurid family, had the remains of two young bird-like dinosaurs called Citipes in its stomach. This finding suggests that young tyrannosaurs had a different diet than their adult counterparts, transitioning from smaller prey to larger plant-eating dinosaurs as they grew. The discovery provides insight into the ontogenetic dietary shift of tyrannosaurs and their success as apex predators.
