Seth Roberts has found that for enough people to make it interesting, a tablespoon of raw honey before going to sleep improves both sleep and (quite surprisingly) strength.
His arguments for why this is plausible don't strike me as very strong, and it seems to me I've heard that dessert is hardly universal, and (very faint memory) there are cultures that put something sweet at a different point in the meal. Anyone have details?
In any case, a dessert after dinner isn't the same timing as something sweet right before bedtime.
I'm going to try out the tablespoon of honey-- I'll post about the effects, if any.
