All food is processed...let me say that again. All food goes through some sort of processing unless you go out to your garden and eat on lettuce leaves like our adorable furry babies. Minimal processing involves only picking a raw vegetable or fruit and rinsing it with water. "Many foods today receive much more extensive processing. For raw salad vegetables this may include the washing, trimming, and packaging after harvest." Canned, boxed and frozen foods receive the most processing. "Some of the things they might be subjected to are cooking, mixing, preservatives, flavor and color enhancers, wrapping, vacuum packing, freezing, or exposed to radiation. As a general rule, each step in the processing scheme can destroy a portion of the nutrients that were in fresh food before harvesting."
