Maybe we should eat foods native to our culture and region. Being from Louisiana, I eat plenty of meat (I have no ethical qualms with animals dying so I can eat meat, its apart of life), vegetables that can grow in the region, starches that also grow in the region e.g.,, converted Louisiana white rice, and take in a good portion of dairy. I don't need my food imported from around the world, I eat what is grown and raised here. Couple that with an active lifestyle and I don't see any need to change.
