The town of Korčula, said to be the home of Marco Polo, was mostly built in the 15th century, and the island's local population were famous for their decorative stone carving work, which to this day still adorn the city's facades. Korčula is also known as a gastronomic destination with many good restaurants that wrap around the edges of the seaside. You may be lucky enough to see a performance of “Moreska” - a dramatic sword dance, which was widespread in the Mediterranean countries in the 11th century, but today only exists here on the island. We will overnight in Korčula Town and enjoy a traditional Croatian dinner in the village of Zrnovo, one of the oldest settlements on the island.
There is evidence that blood tryptophan levels are unlikely to be altered by changing the diet,  but tryptophan is available in health food stores as a dietary supplement .  Consuming purified tryptophan increases brain serotonin level, whereas eating foods containing tryptophan does not.  This is because the transport system , which brings tryptophan across the blood-brain barrier , is also selective for the other amino acids, which are contained in protein food sources .  High blood plasma levels of other large neutral amino acids prevent the plasma concentration of tryptophan from increasing brain concentration levels.
