Health Benefits of Broccoli and Broccoli Sprouts found in Doc Broc Rocks
Promote Optimal Health
Like other cruciferous vegetables, broccoli contains the phytonutrients sulforaphane and the indoles, which have significant anti-cancer effects. Research on indole-3-carbinol shows this compound helps deactivate a potent estrogen metabolite (4-hydroxyestrone) that promotes tumor growth, especially in estrogen-sensitive breast cells, while at the same time increasing the level of 2-hydroxyestrone, a form of estrogen that can be cancer-protective. Indole-3-carbinol has been shown to suppress not only breast tumor cell growth, but also cancer cell metastasis (the movement of cancerous cells to other parts of the body). Scientists have found that sulforaphane boosts the body’s detoxification enzymes, potentially by altering gene expression, thus helping to clear potentially carcinogenic substances more quickly. When researchers at Johns Hopkins studied the effect of sulphoraphane on tumor formation in lab animals, those animals given sulforaphane had fewer tumors, and the tumors they did develop grew more slowly and weighed less, meaning they were smaller. A study published in the cancer journal, Oncology Report demonstrated that sulforaphane, which is a potent inducer of Phase 2 liver detoxification enzymes, also has a dose-dependent ability to induce cell growth arrest and cell death via apoptosis (the self-destruct sequence the body uses to eliminate abnormal cells) in both leukemia and melanoma cells.
Sulforaphane may also offer special protection to those with colon cancer-susceptible genes, suggests a study conducted at Rutgers University and published online in the journal
In this study, researchers sought to learn whether sulforaphane could inhibit cancers arising from one’s genetic makeup. Rutgers researchers Ernest Mario, Ah-Ng Tony Kong and colleagues used laboratory mice bred with a genetic mutation that switches off the tumor suppressor gene known as APC, the same gene that is inactivated in the majority of human colon cancers. Animals with this mutation spontaneously develop intestinal polyps, the precursors to colon cancer. The study found that animals who were fed sulforaphane had tumors that were smaller, grew more slowly and had higher apoptotic (cell suicide) indices.
Additionally, those fed a higher dose of sulforaphane had less risk of developing polyps than those fed a lower dose.
The researchers found that sulforaphane suppressed enzymes called kinases that are expressed not only in animals, but also in humans, with colon cancer. According to lead researcher, Dr. Kong, ‘Our study corroborates the notion that sulforaphane has chemopreventive activity…Our research has substantiated the connection between diet and cancer prevention, and it is now clear that the expression of cancer-related genes can be influenced by chemopreventive compounds in the things we eat.’
Another study, published in Cancer, the journal of the American Cancer Society, looked at indole-3-carbinol (I3C), a naturally occurring component of Brassica vegetables, such as broccoli, cabbage, and Brussels sprouts. I3C has been recognized as a promising anticancer agent against certain reproductive tumor cells. This laboratory study evaluated I3C’s effects on cell cycling progression and cancer cell proliferation in human prostate cancer cells. I3C was shown to suppress the growth of prostate cancer cells in a dose-dependent manner by blocking several important steps in cell cycling and also to inhibit the production of prostate specific antigen (PSA), a protein produced by the prostate whose rising levels may indicate prostate cancer. Researchers noted that the results of this study demonstrate that ‘I3C has a potent antiproliferative effect’ in human prostate cancer cells, which qualifies it as ‘a potential chemotherapeutic agent’ against human prostate cancer. New research has greatly advanced scientists’ understanding of just how Brassica family vegetables such as broccoli, cabbage, cauliflower, 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.
Optimize Your Cells’ Detoxification / Cleansing Ability
For about 20 years, we’ve known that many phytonutrients work as antioxidants to disarm metabolic acids before they can damage DNA, cell membranes and fat-containing molecules such as cholesterol. Now, new research is revealing that phytonutrients in broccoli work at a much deeper level. These compounds actually signal our genes to increase production of alkaline buffers involved in detoxification, the cleansing process through which our bodies eliminate harmful compounds.
The phytonutrients in broccoli and other cruciferous vegetables initiate an intricate dance inside our cells in which gene response elements direct and balance the steps among dozens of detoxification enzyme partners, each performing its own protective role in perfect balance with the other dancers. The natural synergy that results optimizes our cells’ ability to disarm and clear metabolic acids and toxins, including potential carcinogens, which may be why cruciferous vegetables appear to significantly lower our risk of cancer.
Recent studies show that those eating the most cruciferous vegetables have a much lower risk of prostate, colorectal and lung cancer-even whencompared to those who regularly eat other vegetables:
In a study of over 1,000 men conducted at the Fred Hutchinson Cancer Research Center in Seattle, WA, those eating 28 servings of vegetables a week had a 35% lower risk of prostate cancer, but those consuming just 3 or more servings of cruciferous vegetables each week had a 44% lower prostate cancer risk.
In the Netherlands Cohort Study on Diet and Cancer, in which data was collected on over 100,000 people for more than 6 years, those eating the most vegetables benefited with a 25% lower risk of colorectal cancers, but those eating the most cruciferous vegetables did almost twice as well with a 49% drop in their colorectal cancer risk.
A study of Chinese women in Singapore, a city in which air pollution levels are often high putting stress on the detoxification capacity of residents’ lungs, found that in non-smokers, eating cruciferous vegetables lowered risk of lung cancer by 30%. In smokers, regular cruciferous vegetable consumption reduced lung cancer risk an amazing 69%!
How many weekly servings of cruciferous vegetables do you need to lower your risk of cancer? Just 3 to 5 servings-less than one serving a day! (1 serving = 1 cup)
To get the most benefit from your cruciferous vegetables like broccoli, be sure to choose organically grown varieties (their phytonutrient levels are higher than conventionally grown), and steam lightly (this method of cooking has been shown to not only retain the most phytonutrients but to maximize their availability). For a brief overview of the process through which cruciferous vegetables boost our ability to detoxify or cleanse harmful compounds (acids) and examples of how specific phytonutrients in crucifers work together to protect us against cancer, read our pH Miracle Books. The pH Miracle books can be found on amazon.com or at www.phmiracleliving.com
Broccoli definitely proves the adage, ‘Good things come in small packages’ since by weight they provide an even more concentrated source of sulfur-containing phytonutrients than mature broccoli. Researchers estimate that broccoli sprouts contain 10-100 times the power of mature broccoli to boost alkaline buffers that detoxify potential carcinogens! A healthy serving of broccoli sprouts in your salad can offer some great health benefits.
Support Stomach Health for Children of All Ages
A study published in Antimicrobial Agents and Chemotherapy provides support for broccoli’s ability to eliminate Helicobacter pylori (H. pylori). In this study, sulforaphane, a phytonutrient richly abundant in the form of its precursor in broccoli and broccoli sprouts, was able to completely eradicate H. pylori in 8 of 11 laboratory animals that had been infected with the bacterium via the implantation of infected human gastric cells. Results were so dramatic the researchers concluded that sulforaphane-rich broccoli may be of benefit in the treatment or prevention of infection with H. pylori, a primary cause of ulcers. Clinical research is being planned that will hopefully confirm these findings and other similar findings, potentially offering people an effective dietary approach to eliminate H. pylori.
A more recent study published in Inflammopharmacology also supports these findings.
The research team, led by Akinori Yanaka of the University of Tsukuba, Japan, found that in patients with H.pylori infection, a diet including 100 grams of broccoli sprouts per day (about 3 ounces) resulted in a significant reduction of H. pylori and pepsinogen (a biomarker in the blood indicating the degree of gastritis).
The researchers think these beneficial results are due to broccoli sprouts’ especially rich concentration of sulforaphane, which can protect against oxidative (free radical) damage in cells that can damage DNA, potentially causing cancer.
H. pylori infection results in a constant barrage of oxidative damage to the cells that make up the lining of the stomach. Cells can survive against such chronic oxidative stress by increasing their protective arsenal of anti-oxidant enzymes, thereby protecting cells from DNA damage.
Recent studies have shown that the gene encoding Nrf-2 (NF-E2 p45-related factor-2) plays an important role in increasing the production of antioxidant enzymes protective against oxidative stress. Sulforaphane stimulates this nrf-2 gene-dependent production of anti-oxidant enzymes, thereby protecting cells from oxidative injury during H. pylori infection.
The Japanese team recruited 40 patients infected with H. pylori. Each day for two months, 20 patients ate a diet with 100 grams of sulforaphane-rich broccoli sprouts each day for two months, while the remaining 20 ate a diet with 100 grams of alfalfa sprouts instead.
‘We wanted to test alfalfa spouts together with broccoli sprouts,’ Yanaka explained, ‘because the chemical constituents of the two plants are almost identical, except that 100 grams of broccoli sprouts contain 250 milligrams of sulforaphane glucosinolate whereas alfalfa sprouts contain neither sulforaphane nor sulforaphane glucosinolate.’
(Glucosinolates, naturally occurring compounds in cruciferous vegetables such as broccoli, cauliflower and cabbage are enzymatically converted into sulforaphane and other bioactive components when the sprouts are chewed or cut.)
At the end of the two-month dietary regimen, patients consuming 100 grams of broccoli sprouts per day showed significantly less H. pylori and markedly decreased pepsinogen (an indicator of gastric atrophy). Those eating alfalfa sprouts did not show any effect.
‘Even though we were unable to eradicate H. pylori, to be able suppress it and relieve the accompanying gastritis by means as simple as eating more broccoli sprouts is good news for the many people who are infected,’ said Yanaka. Infection with H. pylori is very common worldwide, and some experts estimate that nearly 50% of the American public is infected with the bacterium. In addition, this research provides a deeper understanding of earlier studies suggesting broccoli sprouts have cancer-preventive properties. We now know that by increasing the production of anti-oxidant enzymes that protect against H. pylori-induced DNA damage, these sulforaphane-rich sprouts may also help prevent gastric cancer.
Help for Sun-Damaged Skin
Sulforaphane, an active compound found in Brassica family vegetables has already been shown to boost liver and skin cells’ detoxifying abilities. Now, research conducted at John’s Hopkins University and published in Cancer Letters indicates sulforaphane can help repair sun-damaged skin.
After exposure to a dose of UV light comparable to that which would be received by a person sunbathing by the sea on a clear summer’s day, twice weekly for 20 weeks, test animals were treated with varying doses of broccoli extract applied topically to their backs, 5 days a week for 11 weeks. Broccoli extract counteracted the animals’ skin cells’ carcinogenic response to UV light. Recent research has demonstrated that some sun exposure is essential for good health since it is needed for our production of vitamin D, yet to much may be of concern as skin cancer rates continue to rise due to depletion of the ozone layer. Broccoli sprouts’ ability to repair damage done to sun-exposed skin may offer us a way to receive the benefits of sunlight we need without increasing our risk for skin cancer.
A Cardio-Protective Vegetable
Broccoli has been singled out as one of the small number of vegetables and fruits that contributed to the significant reduction in heart disease risk seen in a recent meta-analysis of seven prospective studies. Of the more than 100,000 individuals who participated in these studies, those who diets most frequently included broccoli, tea, onions, and apples-the richest sources of flavonoids-gained a 20% reduction in their risk of heart disease.
Broccoli and other leafy green vegetables contain powerful phytonutrient antioxidants in the carotenoid family called lutein and zeaxanthin, both of which are concentrated in large quantities in the lens of the eye. When 36,000 men in the Health Professionals Follow-Up Study were monitored, those who ate broccoli more than twice a week had a 23% lower risk of cataracts compared to men who consumed this antioxidant-rich vegetable less than once a month. In addition to the antioxidant potential of broccoli’s carotenoids, recent research has suggested that sulforaphane may also have antioxidant potential, being able to protect human eye cells from free radical stressors.
Stronger Bones with Broccoli
When it comes to building strong bones, broccoli’s got it all for less. One cup of cooked broccoli contains 74 mg of calcium, plus 123 mg of vitamin C, which significantly improves calcium’s absorption; all this for a total of only 44 calories. To put this in perspective, an orange contains no calcium, 69 mg of vitamin C, and 60-about 50% more-calories. Dairy products, long touted as the most reliable source of calcium, contain no vitamin C, but do contain saturated fat. A glass of 2% milk contains 121 calories, and 42 of those calories come from fat.
An Immune System Booster
Not only does a cup of broccoli contain the RDA for vitamin C, it also fortifies your immune system with a hefty 1359 mcg of beta-carotene, and small but useful amounts of zinc and selenium, two trace minerals that act as cofactors in numerous immune defensive actions.
A Birth Defect Fighter
Especially if you are pregnant, be sure to eat broccoli. A cup of broccoli supplies 94 mcg of folic acid, a B-vitamin essential for proper cellular division because it is necessary in DNA synthesis. Without folic acid, the fetus’ nervous system cells do not divide properly. Deficiency of folic acid during pregnancy has been linked to several birth defects, including neural tube defects like spina bifida. Despite folic acid’s wide occurence in food (it’s name comes from the Latin word folium, meaning ‘foliage,’ because it’s found in green leafy vegetables), folic acid deficiency is the most common vitamin deficiency in the world.
Broccoli’s name is derived from the Latin word brachium, which means branch or arm, a reflection of its tree-like shape that features a compact head of florets attached by small stems to a larger stalk. Because of its different components, this vegetable provides a complex of tastes and textures, ranging from soft and flowery (the florets) to fibrous and crunchy (the stem and stalk). Its color can range from deep sage to dark green to purplish-green, depending upon the variety. One of the most popular type of broccoli sold in North America is known as Italian green, or Calabrese, named after the Italian province of Calabria where it first grew.
Other vegetables related to broccoli are broccolini, a mix between broccoli and kale, and broccoflower, a cross between broccoli and cauliflower. Broccoli sprouts have also recently become popular as a result of research uncovering their high concentration of the anti-cancer phytonutrient, sulforaphane.
Broccoli has its roots in Italy. In ancient Roman times, it was developed from wild cabbage, a plant that more resembles collards than broccoli. It spread through out the Near East where it was appreciated for its edible flower heads and was subsequently brought back to Italy where it was further cultivated. Broccoli was introduced to the United States in colonial times, popularized by Italian immigrants who brought this prized vegetable with them to the New World.
How to Select and Store
Choose broccoli with floret clusters that are compact and not bruised. They should be uniformly colored, either dark green, sage or purple-green, depending upon variety, and with no yellowing. In addition, they should not have any yellow flowers blossoming through, as this is a sign of over maturity. The stalk and stems should be firm with no slimy spots appearing either there or on the florets. If leaves are attached, they should be vibrant in color and not wilted.
Broccoli is very perishable and should be stored in open plastic bag in the refrigerator crisper where it will keep for a week. Since water on the surface will encourage its degradation, do not wash the broccoli before refrigerating. Broccoli that has been blanched and then frozen can stay up to a year. Leftover cooked broccoli should be placed in tightly covered container and stored in the refrigerator where it will keep for a few days.
How to Enjoy
Tips for Preparing Broccoli:
Both cooked and raw broccoli make excellent additions to your meal plan. Some of the health-supporting compounds in broccoli can be increased by slicing or chewing, since both slicing and chewing can help activate alkaline buffers in the broccoli. The heating (for example, steaming) of unsliced broccoli is also fine, since it helps to prepare the food in a pureed state for biological transformation into blood in the small intestine. When cooking broccoli, however, the stems and florets should be prepared differently. Since the fibrous stems take longer to cook, they can be prepared separately for a few minutes before adding the florets. For quicker cooking, make lengthwise slits in the stems. While people do not generally eat the leaves, they are perfectly edible and contain concentrated amounts of nutrients.
The World’s Healthiest Foods has long recommended quickly steaming or healthy sautéing as the best ways to cook vegetables to retain their nutrients. Several recent studies have confirmed this advice. The way you cook can dramatically impact the amount of nutrients your vegetables deliver. For more information on healthy cookware go to: http://www.phmiracleliving.com/saladmaster.htm
A study published in the Journal of the Science of Food and Agriculture investigated the effects of various methods of cooking broccoli. Of all the methods of preparation, steaming caused the least loss of nutrients.
Microwaving broccoli resulted in a loss of 97%, 74% and 87% of its three major antioxidant compounds-flavonoids, sinapics and caffeoyl-quinic derivatives. In comparison, steaming broccoli resulted in a loss of only 11%, 0% and 8%, respectively, of the same antioxidants.
Study co-author, Dr. Cristina Garcia-Viguera, noted that ‘Most of the bioactive compounds are water-soluble; during heating, they leach in a high percentage into the cooking water. Because of this, it is recommended to cook vegetables in the minimum amount of water (as in steaming) in order to retain their nutritional benefits.’ A second study, published in the same issue of the Journal of the Science of Food and Agriculture, provides similar evidence. In this study, Finnish researchers found that blanching vegetables prior to freezing caused losses of up to a third of their antioxidant content. Although slight further losses occurred during frozen storage, most bioactive compounds including antioxidants remained stable. The bottomline: how you prepare and cook your food may have a major impact on its nutrient-richness. For more information of how to cook food without losing its electrical potential go to: http://www.phmiracleliving.com/saladmaster.htm
A third study, published in the British Medical Journal, checked to see how much of the B vitamin, folate, was retained after broccoli, spinach or potatoes were boiled or steamed.
Boiling for typical time periods caused a loss of 56% of the folate in broccoli, and 51% of the folate in spinach, while boiling potatoes caused only minimal folate loss. Steaming spinach or broccoli, in contrast, caused no significant loss of folate. The take home message: Boiling potatoes may be okay, but to get the most benefit from cruciferous vegetables like broccoli, and greens like spinach, cook them lightly!
A Few Quick Serving Ideas:
Sprinkle lemon juice and sesame seeds over lightly steamed broccoli.
Toss spinach pasta with olive oil, pine nuts and healthy sautéed broccoli florets. Add salt and pepper to taste.
Purée cooked broccoli and cauliflower, then combine with seasonings of your choice to make a simple, yet delicious, soup.

Broccoli and Goitrogens
Broccoli contains goitrogens, naturally-occurring substances in certain foods that can interfere with the functioning of the thyroid gland. Individuals with already existing and untreated thyroid problems may want to avoid broccoli for this reason. Cooking may help to inactivate the goitrogenic compounds found in food. However, it is not clear from the research exactly what percent of goitrogenic compounds get inactivated by cooking, or exactly how much risk is involved with the consumption of broccoli by individuals with pre-existing and untreated thyroid problems.
Broccoli contains glucosinolates, phytochemicals which break down to compounds called indoles and isothiocyanates (such as sulphoraphane). Broccoli also contains the carotenoid, lutein. Broccoli is an excellent source of the vitamins K, C, and A, as well as folate and fiber. Broccoli is a very good source of phosphorus, potassium, magnesium and the vitamins B6 and E.
