I found that acquiring meat from local farmers and butchers is a lot easier than doing the same for fruits and veg, especially with so many of them being shipped in from around the world. Granted they are making it more difficult for farmers too, but there is a notable difference in taste with grass fed meat.

For the most part, people are using supermarkets to buy their food instead of farmers markets and butchers. Either way, sourcing is important but becomes easier when you're only eating a handful of different foods.
