Identified concepts and relative definitions use for local food.

Concepts	Definition	References
Geographic	Food is produced in a geographic proximity or in a specific political boundary, e.g., Tomato from within a 50 km radius or a German Tomato	[15,17,19,21,25,26,27,28,30,32,33,34,38,41,46,47,51,54,56,57,58,59,60,61,62,63,64,65,66,67,68,69,70,71,72,73,74,75,76,77,78,79,80,81,82,83,84,85,86,87,88,89,90,91,92,93,94,95,96,97,98]
Holistic	Food produced in geographic proximity with trust and connectedness between and within producer groups and consumers. It is mainly represented by short food supply chains and cooperative networks of consumers and producers that commonly pursue to maintain traditional farming practices through new models and social improvement; e.g., Community-Supported Agriculture (CSA)	[14,22,29,35,36,37,39,40,42,43,45,48,49,50,51,52,53,54,56,79,90,97,99,100,101,102,103,104,105,106,107,108,109,110,111,112,113,114,115,116,117,118,119,120,121,122,123,124,125,126,127,128,129]
Regional	Food that represents concepts such as “specialty” and “identity”, containing a differentiation of the food, e.g., Parma Ham	[7,75,76,122,126,130,131,132,133,134,135]
