Information
Vegatables are an important part of a well-balanced diet. Many people wonder if frozen and canned vegetables are as nutritious as fresh vegetables. The answer to this question depends on both the time between the harvesting of the vegetable and the canning and freezing process. Generally, vegetables are canned or frozen immediately upon harvest when their nutrient content is at its peak.
The way vegetables are prepared at home can also affect the nutrient content. Vegetables of any type (fresh, frozen, or canned) that are boiled in large amounts of water for long periods of time lose much of their nutritional content compared with vegetables that are lightly steamed.
Vegetables fresh from the farm or just picked are more nutritious than their frozen or canned counterparts, but frozen and canned vegetables are an acceptable nutritional alternative. Just be mindful of the amount of salt added to canned vegetables; try to buy those without added salt. And, don't overcook any vegetables.
