As usual, more research is needed, and while a catchy title is nice, this isn't anything to change your dietary habits by,

Learnt from my grandmother to eat plenty bananas before bedtime. It helped with my asthma and swear too that it did wonders for my sleep.

Usually had it with a hot curry at dinner time or dessert (sliced bananas, cubed apples and evaparoted milk.)

    Multiple regression analysis indicated that individuals with a higher potassium intake had lower AIS scores.
