It’s not good to eat a heavy meal just before you go to sleep. Also avoid fatty foods and sweets. If you have a drink and really have to eat something before going to sleep, limit it to a light snack. For example, a bowl of yogurt, a piece of cheese, a banana or a hand of almonds.
These products contain tryptophan, a substance that helps you sleep better. But a kiwi can help you too. Kiwi fruit contains folic acid. A folic acid deficiency can lead to insomnia.
