Even your diet can have an impact on how well you sleep. We spoke to Dr. Michael Breus, a sleep specialist and author of "The Sleep Doctor's Diet Plan: Lose Weight Through Better Sleep," to find out what we should be eating (and drinking) to get a better night's rest. Here are 23 foods and drinks that he recommends. BEEF Sydney Kramer Beef is high in tryptophan, an acid "that is involved in the process of making melatonin naturally," Breus said. Melatonin is a hormone that helps regulate your sleep. Beef also contains vitamin B3 and iron, which help alleviate restlessness, according to the sleep doctor.
