I eat lots of brussel sprouts and broccoli- but as food. 2 DIM caps are the equivalent of 2-4 pounds of raw cabbage which makes DIM more of a drug. I took DIM briefly about ten years ago but I now disagree with the routine strategy of the alt med doctors who give out DIM as an anti-estrogen. When I open my mouth about the problems with DIM, it is considered heresy but I have researched it thoroughly.
There has been evidence that DIM can manipulate estrogen, but absolutely NO EVIDENCE that it helps prevent Breast Cancer in humans. I have asked the DIM prescribers to provide evidence and not one can do it. The cell line/ test tube studies are bogus. Only human studies count and they do not exist. A few DIM takers have acquired goiters or developed nodules on their thyroids. These conditions went away when DIM was discontinued.
Goats who over-graze in kale patches have developed goiter. Goiter in tropical countries is often caused my a diet with too much goitrogenic cassava (tapioca).
The Irish researcher, Smyth, has measured the thyroids of Breast Cancer patients and found swollen thyroids indicates risk for breast cancer. He has even correlated the size of the swelling with the stage of breast cancer. So the thyroid expanding to take up more Iodine from the bloodstream is an efficient compensation mechanism in iodine-deficient people. But, it is a bad health sign because cancer and lower IQ often parallel the swollen thyroid.
Um, Wommie, this sound-off was probably more than you wanted to hear. :)
