Eating grapefruit before bed has been an old wives’ tale for years, but as it turns out there’s a reason why this has been known to help sleep. It contains lycopene, an antioxidant in the body that has been shown to improve the way you sleep. This is additional good news, since lycopene has also been shown to help ward off heart disease and cancer, and has anti-aging benefits. Just one more reason to start adding grapefruit to your diet, as well as other foods that contain lycopene. Grapefruit can also help you lose weight if needed, and being at a proper weight can lead to better sleep as well.
