Problem: You Have Trouble Falling and Staying Asleep
There’s an old myth that sugar makes people, especially children, hyperactive. While that isn’t true, sugar can give you a short-lived burst of energy followed by a crash caused by changing glucose levels. These blood sugar fluctuations may also make it difficult for you to fall asleep. In a large study, middle-aged women who had diets high in sugar were more likely to develop sleeping problems like insomnia. Added refined sugar like that in many baked goods and soda had more of an effect on sleep than natural sugars in fruit and other unprocessed food. Another study found that healthy people who ate high-fat diets had poorer quality sleep than those who ate less sugar and more fiber.
