"Considered the ultimate superfood, walnuts are now being served up as brain medicine for many reasons.
We now know that walnuts help develop over 3 dozen neuro-transmitters for brain function. Low omega-3 intake can be linked to depression and cognitive degeneration. They have potential health effects against cancer, aging, inflammation, and neurological diseases. Eating a fistful of walnuts regularly then can keep the spirits up and prop up the grey cells for good measure. What's more walnuts are known to raise melatonin levels by a whopping three times, promising relief from sleeplessness and insomnia.
So if you're tired of counting sheep at night and would appreciate a knock-out sleep instead, then consider ingesting a few walnuts as a pre-bedtime snack."
