The Claim
Migratory birds experience a physiological trade-off between energy efficiency during endurance flight and long-term oxidative damage, such that higher omega-6 polyunsaturated fatty acid content in their fat stores reduces flight energy costs by approximately 11% but increases oxidative damage, indicating a fundamental performance-health compromise in avian endurance athletes under experimental conditions.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Migratory birds burn fat to fly long distances, and when their fat has more omega-6, they use less energy to fly—but it comes at a cost: more cell damage over time. It's like getting better gas mileage in a car that wears out faster.

What the research says
1 studyStudy: The energy savings-oxidative cost trade-off for migratory birds during endurance flight
The study shows that birds burning more omega-6 fat use less energy during flight but suffer more cell damage over time, which matches the idea of a trade-off between performance and health.
