Af hverju
brokkolí?
Líkaminn verður stöðugt fyrir árásum sindurefna sem skaða frumur okkar. Þessar sködduðu frumur skipta sér
líkt og heilbrigðar frumur og er það ferli talin meginorsök fyrir ótímabærri öldrun, hrukkumyndun og
gæti leitt til fjölda sjúkdóma.
Árið 1992 uppgötvuðu vísindamenn ensímið sulforaphane í brokkolí sem örvar líffræðilega ferlið í frumum líkamans, veitir þeim vernd gegn skaðlegum
áhrifum og stuðlar að endurnýjun þeirra. Ferlið sem sulforaphane úr brokkolí hrindir af stað er þekkt undir vísindaheitinu Nrf2.
Heilbrigðar frumur – heilbrigður líkami
Líkaminn er gerður úr milljörðum fruma og segja má að heilbrigði og vellíðan okkar velti á heilbrigði frumanna. Innbyggt varnarkerfi líkamans verndar
frumurnar fyrir skaðlegum áhrifum og stuðlar að endurnýjun þeirra. Þegar á þrítugsaldurinn er komið getur oft reynst erfiðara að virkja þetta innbyggða
kerfi og því stundum þörf á hjálp „til að kveikja á því“ – þar getur sulforaphane úr brokkolí spilað stórt hlutverk.
Margfalt áhrifaríkara en nokkur andoxunarefni í fæðunni
Þegar sulforaphane kemst í snertingu við frumur líkamans berast boð til gena um að auka framleiðslu eigin andoxunarefna í líkamanum – það er margfalt
áhrifaríkara en nokkur andoxunarefni í fæðunni! Í þessu sama ferli myndast einnig detoxensím sem hjálpa líkamanum að losa út eiturefni. Jafnframt
styrkist geta líkamans til eigin framleiðslu á bólgueyðandi efnum auk taugaboðefna sem efla samskipti fruma.
Þetta líffræðilega ferli er lykillinn að heilbrigðum frumum !
Ensímið sulforaphane í brokkolí kann að vera einn öflugasti hvatinn á
varnarkerfi líkamans sem verndar og styrkir frumur okkar og vinnur
þannig gegn ótímabærri öldrun, hrukkumyndun og ýmsum sjúkdómum.

Broccoli kicks canc

Vegetables pack a
roundhouse punch
against cancer, acc
ording to a report
by nutritional
scientist Keith Sin
gletary of the Uni
versity of Illinois.
He added sulforap
hane, a chemical
found in broccoli,
to cultures of hum
an breast cancer c
ells. Within hours,
the cells stop-
ped dividing. Sulfo
raphane seems to
work by interrupti
ng the tiny microt
ubules that nor-
mally pull pairs of
chromosomes apa
rt when cells divid
e. Without the tub
ules, malignant
cells can’t multiply
. And sulforaphan
e seems to leave n

Potent chemical to

COPD is the fo

. ”In COPD,
there is critical lo

If you’re a smok

have found that
eating crucife-
rous vegetables le
d to between a 20
per cent and 55 p
er cent reduction
in lung cancer
risk, depending o
n the type of vege
table and how lon
g the subject had
been a smoker.
The research also
showed that only
the consumption
of raw, as op-
posed to cooked,
cruciferous veget
ables reduced lun

Broccoli beats oth

h benefits
When the Americ
an Journal of Clin
ical Nutrition pub
lished a pa-
per that listed fo
ods most likely t
o prevent colon
cancer, what
stood out? Brocc
oli. Scientists at
the Harvard Scho
ol of Public
Health in Boston
published an art
icle in the same
journal last
October and not
ed that broccoli,
along with spina
ch, helped to mi
nimize risk for
cataracts. When a
nother team of H
arvard scientists l
ooked at how die
t might protect
against stroke, br
occoli’s benefits a
gain came to the
fore, in research p
ublished in the
October 6, 1999
issue of the Journ
al of the America
n Medical Associ
ation. When it
comes to basic nu
trients, broccoli is
a mother lode. O
unce for ounce, b
oiled broccoli
has more vitamin
C than an orange
and as much calci
um as a glass of m
ilk, according
to the USDA’s nu
trient database. O
ne medium spear
has three times m
ore fiber than
a slice of wheat b
ran bread. Brocco
li is also one of t
he richest sources
of vitamin A
in the produce se
ction.

Broccoli extract bo

Scientists in the U

at a broccoli extr

protect the skin a
gainst ultraviolet
(UV) rays, the pr
imary cause
of most skin can
cers. The research
team, in trials wit
h mice and
human volunteers
, found that sulfo
raphane, extracted
from broc-
coli sprouts and a
pplied to the skin
, helps protect cel
ls against the
redness and inflam
mation created by
exposure to the su
n’s UV ra-
diation. The hum
an trial involved s
ix volunteers, each
exposed to UV ra
diation on two
patches on their b
acks, one treated w
ith the broccoli ex
tract, the other no
t. Skin redness
was used as a mea
sure of cell damag
e. When the extra
ct was applied dai
ly during the th-
ree days before UV

by 37 percent, tho
