Locally grown food has not endured travel, and had more nutrients. These nutrients give your body the building blocks and cofactors needed to function efficiently.
If you can talk to the person who grew the food, you can find out their philosophy of farming, and learn what they have used on the plants, and even what types of seeds they use.
Some people describe this as "better than organic" because it reflects the care and approach of the farmer, rather than only adherence to govt regulations.
Thanksgiving Day has so many special aspects that highlight how much we have to be grateful for. You get to pick your focus- family, friends, football, feast, foliage and so much more. It is easy to get swept up in the planning, or to feel sadness if something from the past is no more- Taking a few moments to get quiet, and focus on what is going right can turn that around.
