Cauliflower benefits

Health Benefits

While cauliflower is not a well-studied cruciferous vegetable from a health standpoint, you will find several dozen studies linking cauliflower-containing diets to cancer prevention, particularly with respect to the following types of cancer: bladder cancer, breast cancer, colon cancer, prostate cancer, and ovarian cancer. This connection between cauliflower and cancer prevention should not be surprising, since cauliflower provides special nutrient support for three body systems that are closely connected with cancer development as well as cancer prevention. These three systems are (1) the body’s detox system, (2) its antioxidant system, and (3) its inflammatory/anti-inflammatory system. Chronic imbalances in any of these three systems can increase risk of cancer, and when imbalances in all three systems occur simultaneously, the risk of cancer increases significantly.

Detox Support Provided by Cauliflower

The detox support provided by cauliflower includes antioxidant nutrients to boost Phase 1 detoxification activities and sulfur-containing nutrients to boost Phase 2 activities. Cauliflower also contains phytonutrients called glucosinolates that can help activate detoxification enzymes and regulate their activity. Three glucosinolates that have been clearly identified in cauliflower are glucobrassicin, glucoraphanin, and gluconasturtiian. While the glucosinolate content of cauliflower is definitely significant from a health standpoint, cauliflower contains about one-fourth as much total glucosinolates as Brussels sprouts, about one-half as much as Savoy cabbage, about 60% as much as broccoli, and about 70% as much as kale.

If we fail to give our body’s detox system adequate nutritional support, yet continue to expose ourselves to unwanted toxins through our lifestyle and our dietary choices, we can place our bodies at increased risk of toxin-related damage that can eventually increase our cells’ risk of becoming cancerous. That’s one of the reasons it’s so important to bring cauliflower and other cruciferous vegetables into our diet on a regular basis.

Cauliflower’s Antioxidant Benefits

As an excellent source of vitamin C, and a very good source of manganese, cauliflower provides us with two core conventional antioxidants. But its antioxidant support extends far beyond the conventional nutrients into the realm of phytonutrients. Beta-carotene, beta-cryptoxanthin, caffeic acid, cinnamic acid, ferulic acid, quercetin, rutin, and kaempferol are among cauliflower’s key antioxidant phytonutrients. This broad spectrum antioxidant support helps lower the risk of oxidative stress in our cells. Chronic oxidative stress—meaning chronic presence over overly reactive oxygen-containing molecules and cumulative damage to our cells by these molecules—is a risk factor for development of most cancer types. By providing us with such a great array of antioxidant nutrients, cauliflower helps lower our cancer risk by helping us avoid chronic and unwanted oxidative stress.

Cauliflower’s Anti-inflammatory Benefits

As an excellent source of vitamin K, cauliflower provides us with one of the hallmark anti-inflammatory nutrients. Vitamin K acts as a direct regulator of our inflammatory response. In addition, one of the glucosinolates found in cauliflower—glucobrassicin—can be readily converted into an isothiocyanate molecule called ITC, or indole-3-carbinol. I3C is an anti-inflammatory compound that can actually operate at the genetic level, and by doing so, prevent the initiation of inflammatory responses at a very early stage.

Like chronic oxidative stress and chronic weakened detox ability, chronic unwanted inflammation can significantly increase our risk of cancers and other chronic diseases (especially cardiovascular diseases).

Cauliflower and Cardiovascular Support

Scientists have not always viewed cardiovascular problems as having a central inflammatory component, but the role of unwanted inflammation in creating problems for our blood vessels and circulation has become increasingly fundamental to an understanding of cardiovascular diseases. The anti-inflammatory support provided by cauliflower (including its vitamin K and omega-3 content) makes it a food also capable of providing cardiovascular benefits. Of particular interest is its glucoraphanin content. Glucoraphanin is a glucosinolate that can be converted into the isothiocyanate (ITC) sulforaphane. Not only does sulforaphane trigger anti-inflammatory activity in our cardiovascular system—it may also be able to help prevent and even possibly help reverse blood vessel damage.

Cauliflower and Digestive Support

The fiber content of cauliflower—over 9 grams in every 100 calories—makes this cruciferous vegetable a great choice for digestive system support. Yet the fiber content of cauliflower is only one of its digestive support mechanisms. Researchers have determined that the sulforaphane made from a glucosinolate in cauliflower (glucoraphanin) can help protect the lining of your stomach. Sulforaphane provides you with this health benefit by preventing bacterial overgrowth of Helicobacter pylori in your stomach or too much clinging by this bacterium to your stomach wall.

Other Health Benefits from Cauliflower

The anti-inflammatory nature of glucosinolates/isothiocyanates and other nutrients found in cauliflower has been the basis for new research on inflammation-related health problems and the potential role of cauliflower in their prevention. While current studies are examining the benefits of cruciferous vegetables as a group rather than cauliflower in particular, promising research is underway that should shed light on the potential benefits of cauliflower in relationship to our risk of the following inflammation-related health problems: Crohn’s disease, inflammatory bowel disease, insulin resistance, irritable bowel syndrome, metabolic syndrome, obesity, rheumatoid arthritis, type 2 diabetes, and ulcerative colitis.

Description

All cruciferous vegetables provide integrated nourishment across a wide variety of nutritional categories and provide broad support across a wide variety of body systems as well. For more on cruciferous vegetables see:

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.

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.

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.

Tips for Preparing and Cooking

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 blanch the cauliflower.

The Healthiest Way of Cooking Cauliflower

From all of the cooking methods we tried when cooking cauliflower, our favorite is Healthy Sauté. We think that it provides the greatest flavor and is also a method that allows for concentrated nutrient retention. Begin by cutting cauliflower florets into quarters and let sit for at least 5 minutes to enhance its health-promoting benefits. To Healthy Sauté cauliflower, heat 5 TBS of broth (vegetable or chicken) or water in a stainless steel skillet. Once bubbles begin to form add cauliflower florets (cut into quarters) and turmeric, cover, and Healthy Sauté for 5 minutes. Toss with our Mediterranean Dressing.

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?

Cauliflower as a “Goitrogenic” Food

Cauliflower is sometimes referred to as a “goitrogenic” food. Yet, contrary to popular belief, according to the latest studies, foods themselves—cauliflower included—are not “goitrogenic” in the sense of causing goiter whenever they are consumed, or even when they are consumed in excess. In fact, most foods that are commonly called “goitrogenic”—such as the cruciferous vegetables (including cabbage, broccoli, kale, and cauliflower) and soyfoods—do not interfere with thyroid function in healthy persons even when they are consumed on a daily basis. Nor is it scientifically correct to say that foods “contain goitrogens,” at least not if you are thinking about goitrogens as a category of substances like proteins, carbohydrates, or vitamins. With respect to the health of our thyroid gland, all that can be contained in a food are nutrients that provide us with a variety of health benefits but which, under certain circumstances, can also interfere with thyroid function. The term “goitrogenic food” makes it sound as if something is wrong with the food, but that is simply not the case. What causes problems for certain individuals is not the food itself but the mismatched nature of certain substances within the food to their unique health circumstances. For more, see an An Up-to-Date Look at Goitrogenic Substances in Food.

Introduction to Food Rating System Chart

In order to better help you identify foods that feature a high concentration of nutrients for the calories they contain, we created a Food Rating System. This system allows us to highlight the foods that are especially rich in particular nutrients. The following chart shows the nutrients for which this food is either an excellent, very good, or good source (below the chart you will find a table that explains these qualifications). If a nutrient is not listed in the chart, it does not necessarily mean that the food doesn’t contain it. It simply means that the nutrient is not provided in a sufficient amount or concentration to meet our rating criteria. (To view this food’s in-depth nutritional profile that includes values for dozens of nutrients – not just the ones rated as excellent, very good, or good – please use the link below the chart.) To read this chart accurately, you’ll need to glance up in the top left corner where you will find the name of the food and the serving size we used to calculate the food’s nutrient composition. This serving size will tell you how much of the food you need to eat to obtain the amount of nutrients found in the chart. Now, returning to the chart itself, you can look next to the nutrient name in order to find the nutrient amount it offers, the percent Daily Value (DV%) that this amount represents, the nutrient density that we calculated for this food and nutrient, and the rating we established in our rating system. For most of our nutrient ratings, we adopted the government standards for food labeling that are found in the U.S. Food and Drug Administration’s “Reference Values for Nutrition Labeling.” Read more background information and details of our rating system.
