Some frozen foods are ACTUALLY more nutritious and delicious than their fresh counterparts. Surprisingly, frozen beat out fresh in terms of nutritional content for Vitamin C, beta-carotene (think carrots), and folate in 8 types of produce, according to a few recent studies. When comparing fresh to frozen veggies, all (with the exception of cauliflower) had the same nutritional content for 3 days. After that, the produce that was fresh had FAR LESS vitamin C than that of frozen (especially BLUEBERRIES!).
The second that fresh produce is harvested, it begins losing its’ nutritonal value. Since frozen veggies and fruit are picked and froze at peak quality, expect the nutrients and flavors to last longer.
