100-foot diet

(名詞) 大部分或全部的食物都是取自自家菜園的飲食。

Green Man 365 is a new daily blog about my year of local eating. The challenge: to eat something that I grew myself each and every day for one year....

At first I thought of calling it the 100-foot diet, but Green Man 365 is more retro-futuristic and much more my style.

Customers may even choose to purchase free range chicken meat direct from the farm for their dinner menu, along with the vegetables they may collect from the farm garden, in what can only be described as a 100-foot diet!
