Insomnia affects 14% of the adult population in Spain, around 5.4 million people. The Mediterranean diet favors rest thanks to its high protein content, complex carbohydrates and healthy fats.
Foods that promote rest are those that include tryptophan, an essential amino acid precursor of serotonin and melatonin that the body is not able to synthesize on its own. Melatonin can also be consumed in supplement form, along with melatonin, as it has been shown to help achieve better and longer sleep.
