The English term is... "locally grown food" It is curious that a language that likes creating acronyms for everything has not come up with a single word for this.

I used to prefer buying local products of any kind over imported. Not just food, but also cosmetics and other stuff, including cars and electronics if available. Somehow it also turned out cheaper. But then I moved to the UK and to my surprise found much less choice. You can buy about 10 varieties of Procter&Gamble washing powder but nothing else. This country is more in the grip of large corporations who push the prices down by enforcing such uniformity.
