For example, 1/4 cup of broccoli sprouts contain the same nutrient - content as 2 1/2 cups
of mature broccoli!
They contain a phytonutrient called sulforaphane, which is 50 times more concentrated in broccoli seeds and sprouts than it is
in mature broccoli florets.
Note this individual was making juice from
mature broccoli plants which have many different active substance and are not recommended for source of glucoraphanin / sulforaphane as the young sprouts have up to 100 times higher glucoraphanin levels.
In fact, 3 - 4 day old broccoli sprouts have up to 100x the amount of sulforaphane
as mature broccoli.
So if all cruciferous vegetables contain sulforaphane, why not just
eat mature broccoli and other veggies?
For instance, one study
on mature broccoli noted genotoxic effects at high doses, but the same results were not seen with broccoli sprouts.
Three - day - old broccoli sprouts contain anywhere from 10 - 100 times the amount of chemoprotective compounds found in mature broccoli
As the concentration of sulforaphane is a lot higher in broccoli sprouts than in
mature broccoli, exactly the same decrease in risk theoretically may be had with a weekly intake of slightly over an ounce of sprouts.
Broccoli sprouts are the highest dietary source of sulforaphane, a whopping five times more than
mature broccoli.
As previously mentioned, young broccoli sprouts have up to 100 times more glucoraphanin than
mature broccoli, making them ideal sources if you want to grow or purchase them (R, R).
Keep in mind, broccoli sprouts offer greater nutrient concentration, when compared to
the mature broccoli plant.
Broccoli sprouts, the three - day old starter of the broccoli plant, offer 10 to 100 times more of sulforaphane, a potent cancer - preventive chemical, than
mature broccoli, according to the University of New Hampshire Cooperative Extension Service.
A 1997 Johns Hopkins study determined that broccoli sprouts are anywhere from 10 to 100 times more anti-carcinogenic than
mature broccoli, depending on which variety or cultivar.
Other health - promoting compounds found in cruciferous vegetables such as broccoli sprouts (and
mature broccoli) include:
For example, previous tests15, 16 have revealed that three - day old broccoli sprouts consistently contain anywhere from 10 - 100 times the amount of glucoraphanin — a chemoprotective compound — found in
mature broccoli.
The usually acceptable claim is up to 50 times more potent than
mature broccoli.
Ironically, their study pointed out that the sprouts have less indole glucosinolates than
mature broccoli, which the recent Penn State study considered a good thing with the right genes.
Although Brussels sprouts, cabbage, watercress and radishes all contain glucoraphanin, the real high - ringer in glucoraphanin content is broccoli — specifically, broccoli sprouts, which contain up to 100 times more of this vital precursor than
mature broccoli.
Dr. Tallaly asserted,» The sprouts are not only quantitatively different than
mature broccoli in their concentrations of chemoprotectants [that protect against tumor formation], they are qualitatively different in their profiles.»
