Local fresh produce is best however, frozen is a very close second choice. Frozen produce is harvested at it’s peak and frozen within 1 – 2 days. Conventional and organic produce found in grocery markets, unless it is local, can travel over 1,000 miles. That produce is picked before it’s peak and ripens en route to your local store. The concentration of vitamins and nutrients may be lower than produce that is local fresh or frozen.
