Acorn is a fruit of the oak tree.
Oak trees are present in forests almost everywhere in the world, including Europe, Asia, North Africa, and America.
Acorns have been used in the human diet in the past as a flour or coffee substitute.
Despite its typical taste, it was an acorn always an attractive source of food and people used it. Acorns were one of the basic foods already in the distant past, especially in ancient times and in times of shortage.
But the whole potential as a food resource has been underestimated relative to other plant foods.
Acorns for growth, production, processing, and storage does not require any chemical means.
That is why they have great potential for sustainable development in the diet.
