> Carbohydrates increase insulin release which not only controls blood sugar but has an effect on amino acid ratio too. It basically lowers the blood levels of certain aminos (including precursors to NA (noradrenalin) and DA (dopamine)) that share the 'transport vehicle' with SE through the blood-brain barrier. This means more SE can get through which can cause tiredness in susceptible people.
Sorry, a correction on the above paragraph:
Its TRYPTOPHAN that is involved in the blood-brain cross-over, not SE. But as tryptophan is the precursor for SE everything else still applies.
Sorry for any confusion.
