Frozen vegetables are less nutritious than fresh vegetables

There is probably little nutritional difference between fresh and frozen vegetables. The nutrient content of frozen vegetables can be higher or lower compared with the fresh equivalent. It can be higher because the vegetables destined for freezing may have been picked at peak condition and frozen immediately after harvesting. In comparison, 'fresh' vegetables may lose some nutrients during transport and storage prior to purchase and subsequent cooking.

Frozen vegetables can also lose nutrients if they are blanched prior to freezing. However, because blanching causes some tenderisation, less time is needed to cook frozen vegetables. The length and method of cooking (boiling, pressure cooking, steaming or microwaving) will ultimately have the greatest impact on the nutrient content of the vegetable when it appears on our plates.
