At least 10,000 accidental deaths a year are sleep-related and 200,000 traffic accidents annually are due to driver fatigue. Recent research on sleep deprivation shows that what you eat before and during nighttime work can affect sleepiness. Greasy, heavy, protein foods bring on sleep according to information in The Shiftworker's Handbook.
Drivers can still enjoy eating, though.
Take light, well-balanced meals and eat snacks that are compatible with slower, nighttime digestion. Vegetables, fruit, breads, pasta and potatoes are good, as are low-fat milk, cheeses, and yogurt. If you're planning to sleep before work, make this a lighter and smaller meal. Meals during breaks Eat soup and salad, soup and a light sandwich, or light protein foods and vegetables. Good snacks include low-fat dairy products, fresh and dried fruit, popcorn, cereal, plain cookies, pretzels, and baked crackers.
