Wow! Quite a discussion. Thanks for all the good advice!
knowing where your food comes from is the first step to healthier eating habits.
Buy local if at all possible - not always an option if you live in a big city, or in the middle of winter, lol, but do the best you can with the options available to you. The further away something is grown, the more chemicals are involved in getting it to the stores. Bananas and avacados are two of the worst in that regard for most of us..
If you have good southern exposure windows, and the space to do it, you can grow some things indoors in pots - things like leaf lettuces, spinach or chards, and many herbs can be grown in pots all year round, and are pretty easy to grow, too... but you dont want to use regular potting soil.. you want a good garden composted soil for things like that.
Things that need to flower first wont do so well - like beans, peas, tomatoes, squashes, etc. - they need pollination to fruit, and i doubt you want bees in the house.
however.. they can be started indoors, then moved outdoors when the weather permits (no chance of frost anymore).
Smaller, family owned butcher shops will most likely have better quality, locally sourced meats available than the big grocery chains. (fewer chemicals & hormones in them)
