Crucifers – these vegetables
include arugula, cabbages, Boc choy, broccoli, Brussels sprouts, cauliflower,
kale, collard greens, kohlrabi, mustard greens, mizuna, wasabi, radishes and turnips. Rapeseed grows in cool climates and is the
source of canola oil. What they all have in common is flowers with four petals,
arranged in a cross, how the name “crucifer” was derived. Most originated in
the middle east. Roman conquerors brought these vegetables to the British Isles
around 500 AD. Kale became very popular there.
Most of the crucifers have not been selected for sweetness
or to remove bitterness, which nutritionally is an advantage for health,
because they contain glucosinolates, and the more bitter, the better, (unlike
Betty Botter’s bitter batter.) Kale and Brussels sprouts have the most. They
offer more health benefits than most of the other fruits and vegetables we
normally eat. Most crucifers are helpful in preventing cancer.
Most crucifers are rich in antioxidants, measured with an
ORAC value (oxygen radical absorbance capacity.) Those foods with highest
antioxidants are Kale and Strawberries, (not a crucifer) Broccoli, Grapefruit,
and Grapes are next highest.
To realize their benefits, the vegetables need to be freshly
harvested, but commonly lose 89 % of their potential value in harvest, shipped,
warehoused, and displayed, and then stored in your refrigerator. Cooking
further depletes their benefits.
Broccoli depletes very rapidly after it is picked. Broccoli
needs to be chilled as soon as it is harvested, kept cool and eaten within two
to three days. Most is grown in California or Arizona. If possible buy broccoli
at a Farmer’s market. If you must store it, keep it in a microperforated bag in
your crisper drawer. Look in the supermarket for dark green crowns and closed
buds, with no evident yellowing, and firm stems. Cut ends should be moist and
smooth. Best to buy a whole head of broccoli and prepare it right away.
Frozen broccoli is far less nutritious, as blanching
destroys a third of its glucosinolates before it gets to the freezer..
Raw broccoli gives you up to twenty times more sulforaphane
than cooked, which contains its anti cancer properties. Boiling or steaming for
a maximum of four minutes is better than nuking it. They should be crunchy.
They can be sauted in olive oil with garlic. A microwave destroys half of the
nutrients in broccoli. (Information from Eating

PLEASE NOTE:
I am finding it difficult to keep up with daily tasks, and still
have time to do some of the things that give me joy. I have a lot of yard work
to catch up on. Because of that, I will try to write this blog three times a month, and hope that
helps.
