I try and always buy McCain Young and Tender. They harvest and freeze it at their prime. This means that all the vital nutrients are locked in as quickly as possible. There are also no preservatives and naturally cholesterol free. They also have a huge variety to choose from.
My second choice is Harvestime. I've been dissapointed with Checkers’ House Brand quite a few times already and dont even buy it when it is on special.
Jane Badham, dietitian and CEO of the 5-a-Day for Better Health Trust: "Research shows that the nutritional quality of frozen vegetables is the same as, or in some cases even better than, greengrocer or supermarket vegetables. The key to ensuring their nutritional value is careful handling in the supply chain, strict temperature control and correct cooking methods."
The nutrient content of vegetables starts diminishing soon after harvesting. The longer the vegetables remain in the store or home kitchen, and depending on how they are prepared, the less nutritious they become.
In the case of frozen vegetables, only a small amount of nutrients are lost in the short time between harvesting and freezing.
McCain controls the entire production process of its vegetables, and uses mechanical harvesting methods wherever possible to ensure the delay between harvesting and processing is less than eight hours. It also uses individual quick freezing, to ensure the quality of its frozen vegetables.
