I3C and Cruciferous
Vegetables
– Environmental
estrogens, estrogen
replacement in
women, and an
increasing
estrogen/testosterone
ratio in aging males
represents a
hormonal health
problem.
Indole-3-carbinol
(I3C) is a nutrient
that has been shown
to blunt the
negative effects of
estrogen without
lowering estrogen
levels
and
may
decrease the
risk of
estrogen-related
tumors
including breast and
cervical cancer.25,26
Cruciferous
vegetables are the
main source of I3C.
Cruciferous
vegetables include
broccoli, brussels
sprouts, cabbage,
and cauliflower.
The National Cancer
Institute recommends
consumption of 5-9
servings (2˝-4 ˝
cups) of fruits and
vegetables daily,
but separate
recommendations for
cruciferous
vegetables have not
been established. A
study
published in the
Journal of the
National Cancer
Institute found that
cruciferous
vegetables, but not
other vegetables and
fruit, reduce the
risk of bladder
cancer in men.27
