What dietary choice could help improve a pilot's cognitive function before flying?

Choosing a low-fat meal before flying can contribute positively to a pilot's cognitive function due to its potential to support sustained energy levels and avoid sharp insulin spikes. Low-fat meals typically include a balance of protein and carbohydrates, promoting steady blood sugar levels and preventing the lethargy that can result from high-fat meals, which often take longer to digest.

When pilots consume a meal that is lower in fat, they are more likely to maintain alertness and cognitive performance essential for safe flying. This enhanced state of mental clarity is crucial in the cockpit, where decision-making and quick reactions can have direct safety implications.

In contrast, high-carbohydrate meals and high-sugar snacks can lead to fluctuations in blood sugar levels, potentially resulting in a quick energy boost followed by a crash, which can impair cognitive function. Similarly, high-protein meals, while beneficial in many contexts, may also contribute to a longer digestion period, leading to feelings of fullness and lethargy that could detract from a pilot's focus and alertness during flight.
