These are an important crop of Southern Europe, and a staple food in some parts of Italy and France. They can be boiled and used as a vegetable, or used as a puree, or made into a flour for bread or pancakes. They are rich in many nutrients. They have the highest sugar content of any nut.
Starches of little nutritional value
Most refined starches have little to offer the healthy diet. These include cornflour, cornstarch, potato starch, as well as sago and tapioca (manioc, cassava).
