Red Meat
If you are a vegan or a vegetarian, you will want to skip this one. However, in moderation red meat can help keep your body strong and can help you sleep. It is rich in protein, iron, calcium, as well as other important minerals. Go and enjoy that steak every now and then.
If you add a good chunk of these food ideas to your diet, then you will find that you will sleep better. Your nails and hair follicles will be stronger as well. Stay healthy.
