Many nutritionists advise that we should pay attention to the combinations of foods that we eat together, because this is the only way to better use the benefits of food, which in the right combination is better absorbed by the body. Good combinations include honey and milk. Milk contains the amino acid tryptophan, which helps in the production of seratonin - the hormone of happiness, and melatonin - the hormone that controls the sleep cycle. The carbohydrates in honey, on the other hand, help increase tryptophan levels in the body.
