Sweet Chestnuts Facts

Sweet Chestnut is a native of the Mediterranean and first introduced and grown in the UK  by the Romans , who used the fruits to make a porridge, called pollenta in Latin, which  is still consumed but only in the poorer regions of southern Europe.  It grows well on light and acidic soils and hates chalky, heavy soiled environments but is also a drought resistant tree. Sweet chestnuts are a major food crop in regions where they are grown and are usually not eaten raw but used baked, boiled, roasted or in confectionary.  Chestnuts have also been used to make flour and for animal feed. Compared to other nuts chestnuts are low in protein and especially low in fat.
