Smoothies & Sleep

What is the relationship between a smoothie and your sleep? It doesn't seem obvious at first. Smoothies are my favorite thing to suggest to people, who like to skip breakfast... It's morning, they're tired, they cannot stomach having to eat something, it's too much work or because they are so tired, they have the feeling that they're not hungry. But that step of skipping food in the morning, is actually stressing the body out big time.
