Steaming Vegetables Is a Healthy Preparation
Method
Cooking vegetables in water causes some of the nutrients to leach
out into that same water. For example, boiled broccoli loses glucosinolate, the
compound that may be responsible for its cancer-fighting properties. Steaming
vegetables may help retain more nutrients. Steamed broccoli holds on to more
glucosinolate than boiled or fried broccoli. This 2008 study published in Journal of Agricultural and Food Chemistry
has been followed up by a study conducted at the University of Illinois.
Broccoli is an excellent source of sulforaphane which is a plant compound which
has shown anti-cancer properties. For the sulforaphane to form, another
compound must be present – myrosinase.
Research found that broccoli when steamed retained the myrosinase
necessary to form the cancer-fight sulforaphane. Boling and microwaving broccoli even for one
minute destroyed the myrosinase.

Cut the
vegetables into uniform sizes so that they cook at roughly the same rate and
are all done at the same time. You can mix vegetables, but be aware that more
tender vegetables, like broccoli, will cook faster than denser vegetables, like
carrots. If you want to steam mixed vegetables at the same time, add the
longer-cooking veggies first and then the quicker-cooking veggies after a few
minutes. You can also cut the denser vegetables slightly smaller so that they
cook more quickly and finish at the same time as the rest of the vegetables.
·
Arrange the
vegetables with the toughest, thickest parts in the middle where they will get
more steam and heat.
·
Herbs, spices
and garlic can be added to the water which will enhance flavor. Another option
is to replace water with broth.
No matter how you slice it, vegetables are good for you pretty much any way you prepare them, and most of us don’t eat enough of them.
