Are fresh vegetable brought at a grocery store fresher than frozen vegetables?
It's quite common for a lot of people to assume that fresh vegetables are fresher than frozen vegetables. In fact, many wrongly assume that freezing destroys nutrients. Nothing could be farther from the truth. To survive transportation and storage, fresh vegetables are often harvested prematurely at sub-par nutrition levels. On the other hand, frozen vegetables are harvested close to peak maturity and nutrition levels.

Unless you have your own kitchen garden or have access to a farmers market located close to where the vegetables are actually grown, frozen is a better bet - it's fresher, more convenient and rather crucially, more easily accessible for you to improve the health quotient of your meals. It's better to eat frozen peas all through the year than be puritanical about enjoying it only during winter. Eating healthily is as much a behavior science problem as it is a nutrition science problem, and it's easier to keep frozen peas around and eat it regularly than to try and remember what is currently in season and go out of the way to procure them fresh all the time. Long term convenience always trumps short term will power improvements.
