Cooking vegetables until they turn soggy and limp removes most of its nutrients. To get optimum nutrition from your vegetables, avoid boiling them for long periods as this process leaches the nutrients out of it. Instead, stir frying them lightly is a better way to preserve their nutrients. Alternatively, blanch them in hot water if you intend to eat them in a soup. Just make sure that your vegetables are still firm and lightly crisp when eaten.
