RFF#88 – Bananas contain serotonin

But unfortunately, orally ingested serotonin can’t cross the blood brain barrier. So despite the neuro-chemicals they possess, bananas cannot be prescribed as an anti-depressive therapy.

I learned about this fact from: Gharibzadeh et al, Depression and Fruit Treatment, J Neuropsychiatry Clin Neurosci. 2010;22(4).

RFF#10 – Carbohydrates promote the release of serotonin in your brain, which makes you feel happy

It’s no wonder carbs are a classic comfort food. The effect of carbohydrates on our mood has been known for centuries. Apparently, when Marco Polo brought pasta back from China, Emperor Fredrick III described pasta using the Greek word “makarios”, which means “happy”.
