Health questions: does microwaving vegetables destroy their nutrients?

No

Many people avoid microwaving vegetables for fear that microwave energy is dangerous. They might choose steaming or stir-frying instead because these cooking methods are thought to be safer and better for preserving nutrients.

But Karen Chong, a registered dietitian from Matilda International Hospital, says microwaving veggies is just as acceptable - and in some cases more convenient - than steaming or stir-frying.

Just follow a few rules, she says. Don't microwave for too long to avoid loss of nutrients and don't put the vegetables in water because their nutrients may leak out. Also, don't chop vegetables too finely - the increased surface area makes for a greater loss of vitamins and minerals.

These rules should also be applied to steaming, stir-frying, boiling and roasting. Basically, every cooking method can destroy nutrients in food.

You have to watch the cooking time, temperature and the amount of water.
