We've all had one of those nights where raiding the biscuit tin or tucking into a plate of cheese on toast seems like the perfect thing to do before heading to bed.
But beside the obvious (hello, midnight chocolate feast) could some foods actually be preventing you from getting a good night's sleep?
A busy lifestyle and growing addiction to technology (yes, we know you're reading emails in bed) means that we don't get enough sleep.
With experts recommending that the average adult should be clocking up eight hours per night, could your diet be a good place to start in making sure you get an uninterrupted night?
Health writer Paola Bassanese said: "We underestimate the importance our gut has on our overall wellbeing. Yet, vital hormones like serotonin, which regulates sleep, are produced in the gut so any dysfunction in our digestion can have a snowball effect on our overeall health.
So, what is the key to good sleep? Making healthier food choices, practicing relaxation techniques like mindful meditation and cutting out stimulants like coffee. And remembering that our gut is our powerhouse just like a car's engine.'
So, make sure your midnight feast doesn't consist of these...
