Raisins are the Cretans’ secret for health as they contain many vitamins (Α, Β1, Β2, Β3, Β6) . Nuts are also a favourite for locals . They are rich in linoleic and linolenic acid , substances necessary for the function of cells , as well as the best protection for the heart . A great percentage of the nuts produced in Crete come from self-sown trees which grow in the wild without any special care or cultivation.
