Younger Broccoli, Healthier You
Chloroplex's sulforaphane from broccoli sprouts can cut your risk of cancer
High vegetable intake has long been associated in epidemiological studies with a decreased risk of various human cancers. In 1985, the Life Extension Foundation became the first organization to offer plant extracts for the purpose of reducing the risk of cancer.
At that time, the most convincing controlled study showed that increased intake of green and yellow vegetables reduced cancer incidence by 70 percent, compared with low vegetable intake, in a group of 1,271 Massachusetts residents. This large-scale human study confirmed previous studies showing that vegetables reduce cancer risk.
The best-documented anti-cancer vegetable is broccoli. The media has eagerly reported scientific studies showing that the consumption of broccoli dramatically lowers cancer incidence. The component in broccoli that has been shown to protect against cancer is called sulforaphane.
A study conducted at Johns Hopkins University School of Medicine has revealed that mature broccoli contains very little sulforaphane, but that very young broccoli sprouts contain abundant amounts. Further, the Johns Hopkins scientists showed that sulforaphane from young, 3-day-old broccoli sprouts was highly effective in reducing the incidence, multiplicity and rate of development of mammary tumors in rats.
The scientists concluded that small quantities of young broccoli sprouts may protect against the risk of cancer as effectively as much larger quantities of mature broccoli.
Based upon the results of the Johns Hopkins study, the Life Extension Foundation immediately sought a 3-day-old broccoli sprout extract containing a standardized amount of sulforaphane. We knew that very few people eat enough broccoli to significantly reduce their risk of cancer, underscoring the need for a concentrated extract in supplement form.
The results of the Foundation's efforts is a broccoli sprout powder that provides the same amount of sulforaphane in one milligram of powder as one could obtain in 1,000 mg of fresh mature broccoli.
The new Chloroplex contains 125 mg of broccoli sprout powder to provide (in each capsule) the amount of sulforaphane found in 4 ounces of fresh mature broccoli, or about one serving.
Since the Food and Drug Administration deregulated dietary supplements in 1994, the quality of available plant extracts has improved greatly, providing the consumer with more potent doses of disease-preventing phytoextracts such as lycopene and lutein.
The new Chloroplex contains an array of new carotenoids and other plant extracts shown to significantly reduce the risk of cancer, macular degeneration, and heart disease.
Depending on your vegetable intake, the suggested dose of the new Chloroplex is one to three capsules a day. It is especially recommended that you take Chloroplex when eating such various carcinogenic foods as charbroiled meat, nitrosamine-preserved meat, aflatoxin-contaminated corn or peanut products, fried foods, and pesticide/herbicide-laden produce and meat.
