Cabbage can provide you with some special cholesterol-lowering benefits if
you will cook it by steaming. The fiber-related components in cabbage do a
better job of binding together with bile acids in your digestive tract when
they've been steamed. When this binding process takes place, it's easier for
bile acids to be excreted, and the result is a lowering of your cholesterol
levels. Raw cabbage still has cholesterol-lowering ability, just not as much as
steamed cabbage.
Researchers now realize that different types of cabbage (red, green, and Savoy) contain different
patterns of glucosinolates. This new knowledge means that your broadest health
benefits from cabbage are likely to come from inclusion of all varieties in
your diet. Cabbage in general—but also Savoy
cabbage in particular—turns out to be an especially good source of sinigrin.
Sinigrin is one of the cabbage glucosinolates that has received special
attention in cancer prevention research.
In one recent study, short-cooked and raw cabbage were the only types of
cabbage to show cancer-preventive benefits—long-cooked cabbage failed to
demonstrate measurable benefits. New research shows that steaming is a better
cooking method than microwaving if you want to maximize the health benefits of
glucosinolates found in cabbage. That's because two minutes of microwaving
destroys the same amount of myrosinase enzymes as seven minutes of steaming,
and you need those myrosinase enzymes to help convert cabbage's glucosinolates
into cancer-preventive compounds.
You'll want to include cabbage as one of the cruciferous vegetables you
eat on a regular basis if you want to receive the fantastic health benefits
provided by the cruciferous vegetable family. At a minimum, include cruciferous
vegetables as part of your diet 2-3 times per week, and make the serving size
at least 1-1/2 cups. Even better from a health standpoint, enjoy cabbage and
other vegetables from the cruciferous vegetable group 4-5 times per week, and
increase your serving size to 2 cups.
While green cabbage is the most commonly eaten variety of cabbage, we
highly recommend trying red cabbage because of it added nutritional benefits
and its robust hearty flavor. We don't think you will be disappointed. The rich
red color of red cabbage reflects it concentration of anthocyanin polyphenols,
which contribute to red cabbage containing significantly more protective
phytonutrients than green cabbage.
A recent study showed that a 100 gram (about 3 ounces) serving of raw red
cabbage delivers 196.5 milligrams of polyphenols, of which 28.3 milligrams are
anthocyanins. Green cabbages yielded much less per 100 grams: 45 milligrams of
polyphenols including 0.01 milligram of anthocyanins. The vitamin C equivalent,
a measure of antioxidant capacity, of red cabbage is also six to eight times
higher than that of green cabbage. Red cabbage is one of the most nutritious
and best tasting vegetables around — a great addition to your Healthiest Way of
Eating.
Cancer prevention tops all other areas of health research with regard to
cabbage and its outstanding benefits. More than 475 studies have examined the
role of this cruciferous vegetable in cancer prevention (and in some cases,
cancer treatment). The uniqueness of cabbage in cancer prevention is due to the
three different types of nutrient richness found in this widely enjoyed food.
The three types are (1) antioxidant richness, (2) anti-inflammatory richness,
and (3) richness in glucosinolates.
Cabbage ranked in wellness Foods rating system as an excellent source of
vitamin C and a very good source of manganese. But in terms of antioxidants in
the newer, phytonutrient category, cabbage is impressive, even among
cruciferous vegetables. Polyphenols rank at the top of the list for
phytonutrient antioxidants in cabbage. In fact, one group of researchers has
described polyphenols as the primary factor in cabbage's overall antioxidant
capacity.
Even white cabbage (a very lightly-colored form of green cabbage and the
most commonly eaten variety of cabbage in the U.S.) provides about 50 milligrams
of polyphenols in a half-cup serving. Red cabbage is even more unique among the
cruciferous vegetables in providing about 30 milligrams of the red pigment
polyphenols called anthocyanins in each half cup. (These anthocyanins qualify
not only as antioxidant nutrients, but as anti-inflammatory nutrients as
well.)
Long-established in health research is the role of cabbage juice in
helping heal stomach ulcers (called peptic ulcers), but more recent studies on
cabbage have looked at the overall health benefits of this food for the stomach
and digestive tract as a whole. Present-day studies make it clear that cabbage
contains a variety of nutrients of potential benefit to our stomach and
intestinal linings. These nutrients include glucosinolates (and the
anti-inflammatory isothiocyanates or ITCs made from them), antioxidant
polyphenols, and the amino acid-like substance called glutamine.
