Broccoli sprouts may help prevent stomach cancer !










Pict., of Broccoli (Structures of DIM & Sulforaphane respectively)

We knew that Broccoli has anticancer activity due to the presence Diindolylmethane, DIM (Str-1). DIM is a natural compound formed during the autolytic breakdown of glucobrassicin present in food plants of the Brassica genus, including broccoli, cabbage, Brussels sprouts, cauliflower and kale. The autolytic breakdown of glucobrassicin requires the catalytic reaction of the enzyme myrosinase which is endogenous to these plants and released upon rupture of the cell wall

(the same compound, has been tested for viral nfections,bacterial infections and immune deficiency diseases also). And boiling the Broccoli, will lead to the loss of this
compound has been also established
Now more interestingly, Dr. Jed Fahey has come out with something different and this time they have mentioned about a phytochemical from broccoli, i.e., sulforaphane. Though the cancer protective effects of sulforaphane is known two decades ago, but this is the first study to show an effect of broccoli in humans on the bacterial infection that leads to stomach cancer. In this study, researchers enrolled 48 Helicobacter-infected Japanese men and women and randomly assigned them to eat 70 grams of fresh broccoli sprouts daily for eight weeks or an equivalent amount of alfalfa sprouts.

Researchers assessed the severity of H. pylori infection at enrollment, and again at four and eight weeks using standard breath, serum and stool tests. H. pylori levels were significantly lower at eight weeks on all three measures among those patients who had eaten broccoli sprouts, while they remained the same for patients who had eaten alfalfa sprouts.
A reduction in H. pylori is expected to lead to a reduction in stomach cancer due to their well-established cause-and-effect link. Stomach cancer has a grim prognosis and is the second most common and the second deadliest cancer worldwide. Congrats Dr. Jed Fahey and group...
