Cauliflower Fridays

I like to broaden my horizons on Fridays, as I prepare to get some other things accomplished this weekend. Last week I posted news you can use on watermelon, one of my all time favorite snacks.  This week I want to touch on a vegetable that doesn't get the nod that it deserves.  I think cauliflower is one of the neglected vegetables because of the bland color and taste. According to WHfoods it ranks right up there with many others in Vitamin C and other health benefits. Is is still healthy covered in butter or maybe some Ranch dressing???  Or is that kind of like buying the reduced fat chips and eating twice as much..........

The milk, sweet, almost nutty flavor of cauliflower is at its best from December through March when it is in season and most plentiful in your local markets.

Cauliflower lacks the green chlorophyll found in other members of the cruciferous family of vegetables like broccoli, cabbage and kale, because the leaves of the plant shield the florets from the sun as they grow. It has a compact head (called a "curd"), usually about six inches in diameter that is composed of undeveloped flower buds. The flowers are attached to a central stalk.

Health Benefits

Cauliflower and other cruciferous vegetables, such as broccoli, cabbage, and kale, contain compounds that may help prevent cancer. These compounds appear to stop enzymes from activating cancer-causing agents in the body, and they increase the activity of enzymes that disable and eliminate carcinogens.

Epidemiological studies have long suggested a connection between these vegetables and resistance to cancer. However, only in the past decade have we begun to understand how these compounds work.


New Research Expands our Understanding of How Cruciferous Vegetables Help Prevent Cancer

New research has greatly advanced scientists' understanding of just how cruciferous vegetables such as cabbage, cauliflower, broccoli, kale and Brussels sprouts help prevent cancer. When these vegetables are cut, chewed or digested, a sulfur-containing compound called sinigrin is brought into contact with the enzyme myrosinase, resulting in the release of glucose and breakdown products, including highly reactive compounds called isothiocyanates. Isothiocyanates are not only potent inducers of the liver's Phase II enzymes, which detoxify carcinogens, but research recently conducted at the Institute for Food Research in the U.K. shows one of these compounds, allyl isothicyanate, also inhibits mitosis (cell division) and stimulates apoptosis (programmed cell death) in human tumor cells.


A Weekly Serving of Cruciferous Vegetables Halves Advanced Prostate Cancer Risk

A study of 29,361 men, enrolled on the Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial found that men who ate more than a serving of either broccoli or cauliflower each week almost halved their risk of developing advanced-stage prostate cancer (cancer that had spread beyond the prostate gland), compared with their peers who ate these vegetables less than once a month.

Specifically, compared to men eating broccoli just once a month, those eating a weekly serving lowered their risk of advanced prostate cancer by 45%. Cauliflower was even a bit more protective. Compared to men eating one serving of cauliflower per month, those enjoying a weekly serving lowered their risk of advanced prostate cancer by 52%. (Kirsch VA, Peters U. et al., J Natl Cancer Inst.)


Protection against Rheumatoid Arthritis

While one study suggests that high doses of supplemental vitamin C makes osteoarthritis, a type of degenerative arthritis that occurs with aging, worse in laboratory animals, another indicates that vitamin C-rich foods, such as cauliflower, provide humans with protection against inflammatory polyarthritis, a form of rheumatoid arthritis involving two or more joints.

The findings, presented in the Annals of the Rheumatic Diseases were drawn from a study of more than 20,000 subjects who kept diet diaries and were arthritis-free when the study began, and focused on subjects who developed inflammatory polyarthritis and similar subjects who remained arthritis-free during the follow-up period.

Subjects who consumed the lowest amounts of vitamin C-rich foods were more than three times more likely to develop arthritis than those who consumed the highest amounts.


Cardiovascular Benefits

Consumption of cruciferous vegetables, such as cauliflower, is known to reduce the risk of a number of cancers, especially lung, colon, breast, ovarian and bladder cancer. Now, research reveals that crucifers provide significant cardiovascular benefits as well.

Researchers from the University of Hawaii have shown that, at the tiny concentration of just 100 micromoles per liter, a phytonutrient found in cruciferous vegetables, indole-3-carbinol, lowers liver cells' secretion of the cholesterol transporter, apolipoproteinB-100 by 56%! Apolipoprotein B-100 (apoB) is the main carrier of LDL cholesterol to tissues, and high levels have been linked to plaque formation in the blood vessels.

When liver cells were treated with I-3-C, not only was apoB-100 secretion cut by more than half, but significant decreases also occurred in the synthesis of lipids (fats), including triglycerides and cholesterol esters. (Maiyoh GK, Kuh JE, et al., J Nutr.)


Description

Cauliflower, a cruciferous vegetable, is in the same plant family as broccoli, kale, cabbage and collards. It has a compact head (called a "curd"), with an average size of six inches in diameter, composed of undeveloped flower buds. The flowers are attached to a central stalk. When broken apart into separate buds, cauliflower looks like a little tree, something that many kids are fascinated by.

Surrounding the curd are ribbed, coarse green leaves that protect it from sunlight, impeding the development of chlorophyll. While this process contributes to the white coloring of most of the varieties, cauliflower can also be found in light green and purple colors. Between these leaves and the florets are smaller, tender leaves that are edible.

Raw cauliflower is firm yet a bit spongy in texture. It has a slightly sulfurous and faintly bitter flavor.


History

Cauliflower traces its ancestry to the wild cabbage, a plant thought to have originated in ancient Asia Minor, which resembled kale or collards more than the vegetable that we now know it to be.

The cauliflower went through many transformations and reappeared in the Mediterranean region, where it has been an important vegetable in Turkey and Italy since at least 600 B.C.

It gained popularity in France in the mid-16th century and was subsequently cultivated in Northern Europe and the British Isles. The United States, France, Italy, India and China are countries that produce significant amounts of cauliflower.


How to Select and Store

When purchasing cauliflower, look for a clean, creamy white, compact curd in which the bud clusters are not separated. Spotted or dull-colored cauliflower should be avoided, as well as those in which small flowers appear.

Heads that are surrounded by many thick green leaves are better protected and will be fresher. As its size is not related to its quality, choose one that best suits your needs.

Store uncooked cauliflower in a paper or plastic bag in the refrigerator where it will keep for up to a week. To prevent moisture from developing in the floret clusters, store it with the stem side down.

If you purchase pre-cut cauliflower florets, consume them within one or two days as they will lose their freshness after that. Since cooking causes cauliflower to spoil quicker, consume it within two to three days of placing in the refrigerator after cooking.


How to Enjoy

Tips for preparing cauliflower

Cauliflower florets are the part of the plant that most people eat. However, the stem and leaves are edible too and are especially good for adding to soup stocks.

To cut cauliflower, first remove the outer leaves and then slice the florets at the base where they meet the stalks. You can further cut them, if you desire pieces that are smaller or of uniform size. Trim any brown coloration that may exist on the edges.

Cauliflower contains phytonutrients that release odorous sulfur compounds when heated. These odors become stronger with increased cooking time. If you want to minimize odor, retain the vegetable's crisp texture, and reduce nutrient loss, cook the cauliflower for only a short time.

Some phytonutrients may react with iron in cookware and cause the cauliflower to take on a brownish hue. To prevent this, add a bit of lemon juice to the water in which you blanche the cauliflower.



A few quick serving ideas:

Healthy sauté cauliflower with garlic, minced ginger and tamari.

For cauliflower with a vivid yellow color, "healthy sauté" it briefly with a spoonful of turmeric or generous pinch of saffron.

Puree cooked cauliflower, add fennel seeds and your other favorite herbs and spices and serve as soup.

Because of its shape and taste, cauliflower florets make wonderful crudite for dipping in sauces.


Individual Concerns

Cauliflower and Purines

Cauliflower contains naturally-occurring substances called purines. Purines are commonly found in plants, animals, and humans. In some individuals who are susceptible to purine-related problems, excessive intake of these substances can cause health problems. Since purines can be broken down to form uric acid, excess accumulation of purines in the body can lead to excess accumulation of uric acid. The health condition called "gout" and the formation of kidney stones from uric acid are two examples of uric acid-related problems that can be related to excessive intake of purine-containing foods. For this reason, individuals with kidney problems or gout may want to limit or avoid intake of purine-containing foods such as cauliflower. For more on this subject, please see "What are purines and in which foods are they found?"


Nutritional Profile

One cup of boiled cauliflower is an excellent source of vitamin C (91.5% of the DV), folate (13.6% of the DV), and dietary fiber (13.4% of the DV). That same amount of cauliflower also serves as a very good source of vitamin B5, vitamin B6, manganese and omega-3 fatty acids.
