Good question! In this section Plusonline goes in search of answers to nagging questions. This time: Are vitamins and minerals in vegetables lost through roasting?
Roasting vegetables in the oven or on a grill pan is tasty and easy. You can do this with many types of vegetables, such as tomatoes, courgettes, peppers and celery. But what about the vitamins and minerals?
Minerals are stable when heated and so are not lost when roasting vegetables. However, vitamins are quickly lost through preparation and heating. The longer they are heated, the more vitamins are lost. Though they will never completely disappear. To get enough vitamins and minerals, it is wise to alternate. Also with vegetables. So, in addition to grilled vegetables, regularly eat cooked and raw vegetables.
Storage advice
In addition, the Nutrition Center advises to store vegetables in a cool, dark place or in the freezer to preserve vitamins. Cut vegetables should also not be stored for too long, because otherwise especially vitamin C and folic acid will be broken down.
