Q: Can diet affect sleep?
– John in California

A: Yes, I discuss this topic in length in my book, Food & Mood. Avoid eating large or spicy meals in the evening, since they might make you groggy, but they interfere with a good night’s sleep. Avoid coffee and other caffeinated beverages and foods after 12 noon. Caffeine can linger in the body for 12 hours or more. About 45 minutes to an hour prior to bedtime, have a small, all-carbohydrate snack, such as a small bowl of popcorn, a half English muffin topped with jam, or a half bagel with honey drizzled on the top. This will help boost levels of a nerve chemical called serotonin that aids sleep. -Elizabeth Somer
