  Determination and Health Implication of the Erucic Acid Content of Broccoli Florets   (Site not responding. Last check: 2007-11-05)
The erucic acid content of broccoli florets, sprouts, and seeds was found to be about 0.8, 320, and 12100 mg/100 g, respectively.
Using the erucic acid limit established for canola oil in the U.S.A. and Canada as a guideline, the estimated dietary intake of erucic acid from florets and sprouts was considered of little consequence, whereas in seeds a relatively small amount (about 35 g/wk) equaled our calculated exposure limit for erucic acid.
Additionally, the most complete fatty acid distribution yet published for the various forms of broccoli are presented.

  Erucic acid - Wikipedia, the free encyclopedia
Erucic acid is a fatty acid found in rapeseed, wallflower seed, and mustard seed, making up 40 to 50 percent of their oil.
Erucic acid is used to produce emollients, surfactants, and other chemicals.
Erucic has been shown to have a variety of health impacts in studies, and foods containing large amounts of erucic acid are considered unfit for human consumption in many countries.

Industrially, fatty acids are produced by the hydrolysis of the ester linkages in a fat or biological oil (both of which are triglycerides), with the removal of glycerol.
Linoleic acid and arachidonic acid are omega-6 fatty acids.
Oleic and erucic acid are omega-9 fatty acids.

 Whole Foods Market : Issues & Actions : Labeling : Canola   (Site not responding. Last check: 2007-11-05)
Canola oil (it's named derived from Canadian oil) is a specially bred "low erucic acid" variety of rapeseed that was created after studies showed rats fed traditional rapeseed oil containing up to 40% erucic acid developed fatty degeneration of heart, kidney, adrenals, and thyroid.
Subsequent studies, however, showed that rats had the same type of problems with other oils that didn't even contain erucic acid, indicating that the initial conclusions indicting erucic acid as the culprit were false.
Erucic acid was bred out of canola from rapeseed's 40% erucic acid down to less than 0.02 to 0.01% to create a more neutral flavor, not because of health considerations.

A fatty acid found in large amounts in rape and mustard seed oils, and widely (but mistakenly) thought to be toxic.
As reported by nutritionist and oil expert Udo Erasmus PhD, the rat studies which showed fatty degeneration of heart, kidneys and glands after the consumption of erucic acid, were interpreted to mean that erucic acid is also toxic to humans.
Erucic acid has been used to treat a fatal degenerative disease known as adrenoleukodystrophy (ALD) and is sometimes known as 'Lorenzo's oil', after the boy who inspired the development of the treatment.

 Rapeseed, a New Oilseed Crop for the United States
This is almost entirely due to the plant breeding work initiated in Canada in the 1950s and 1960s which greatly reduced the levels of two anti-nutritional compounds, erucic acid in the oil and glucosinolates in the meal, creating a new, high-value oil and protein crop known as canola in Canada and the United States.
