Frozen vs. Fresh Vegetables

"The nutritional value of fresh vegetables is determined by their seasonality and availability in the area. Many vegetables have travelled far distances to land in the produce section of your chain grocery store. When the vegetables are shipped across the country, they are exposed to extreme temperatures which release their important nutrients like vitamin A and C. Many fresh vegetables, which need to be shipped great distances, have also been harvested before they are ripe (before vitamins and nutrients have had a chance to fully develop within the vegetable)." - fitday.com
