Most people would agree that nothing beats the texture and flavor of fresh vegetables picked from your own garden or purchased from a local farmers' market. Still, you might wonder if fresh is always best. Although they taste better, are fresh vegetables nutritionally superior to their frozen counterparts?
Frozen Vegetables
The nutritional content of a frozen vegetable depends on the quality of the fresh product before it is frozen. If picked at its peak and frozen promptly, a vegetable retains its nutrient value at the time of freezing. However, the way produce is packaged can affect nutritional quality. For example, some produce is frozen using added sugars or sodium to help maintain its overall quality. Furthermore, the nutritional profile of some vegetables like broccoli changes with the removal of their stalks or skins. Broccoli stalks tend to be higher in calcium and lower in beta-carotene than florets; thus, removal affects the overall density of certain nutrients.
Fresh Vegetables
The only true fresh vegetables are the ones you pick from the garden or buy from a local farmer and eat almost immediately. These vegetables, picked at their peak and consumed quickly, typically provide the most nutrition. However, because many nutrients are light sensitive, the amount of time that a vegetable spends on the counter or in the crisper can adversely affect its nutrient content.
Pseudo Fresh Vegetables
A pseudo fresh vegetable refers to produce that is purchased from the grocery store. Though labeled fresh, some of this produce spends days in transit and even more time on the store's shelves. Add to that the time it spends in your refrigerator or on your counter, and you have a fresh product that is no longer so fresh. As vegetables age, the amount of sugar versus starch changes, affecting flavor, texture and nutritional quality.
Other Factors
Cooking methods affect the nutrient content of both fresh and frozen vegetables. The desirable cooking method depends on the particular vegetable. For example, while grilling or baking with skins will guarantee your potatoes yield the greatest amounts of nutrients, steaming or microwaving is often a better choice for cauliflower. Most frozen products come with directions on how to properly prepare them to guarantee the most desirable end product. In general, whatever method you use, vegetables should be minimally cooked.
Which Is Healthier
Many factors affect the nutritional quality of fresh and frozen vegetables by the time they end up on your plate. To ensure you are getting the healthiest and best product, choose unbruised fresh produce that is not discolored or wilted, and frozen produce that is not packed with added salt or sugar. Use fresh vegetables quickly or store them appropriately to reduce any nutrition loss associated with aging. Finally, research the best preparation and cooking method for a particular fresh food or follow the cooking directions for frozen items to avoid overcooking.
