As many as seventy million Americans have been diagnosed with sleep disorders, such as sleep apnea or insomnia, that prevents at least seven hours of good sleep each night. A new study helps explain why. A clinical nutritionist and registered dietitian at George Mason University points to how we eat as indicators of sleep disorders. Types of food we eat and blood sugar patterns were shown to affect how well we sleep. People with diabetes were ore likely to have trouble sleeping compared to those without diabetes. The study, appearing in the journal Frontiers in Nutrition, also found low-protein, combined with high-fat diets were consistently linked to poor sleep. However, low-carb diets were associated with lower chances of short-sleep duration.
