What Works Better for Hormones--Soy or Flax?
Researchers have found postmenopausal women who supplement their diets with flaxseed, as opposed to soy, have a greater chance of reducing their risk of osteoporosis and hormone-sensitive cancers.
The structural similarity of the phytoestrogens enterolactone and enterodiol from flaxseed and genistein and daidzein from soy suggests that they may interfere with estrogen metabolism. Modulation of estrogen metabolism has the capacity to influence tissue estrogen exposure and therefore affect chronic disease.
Researchers conducted a study on postmenopausal women who were either supplemented with a placebo, soy or flaxseed, in the form of a muffin, for a four-month period. Participants contributed blood and urine samples during the beginning and ending of the study. Researchers analyzed the urine samples for phyteostrogens (2-hydroxyestrone, 16-hydroxyestrone), estrogen metabolites, and serum hormones. They also analyzed the urine and serum samples for biochemical markers of bone metabolism.
Results from the study show urinary concentrations of 2-hydroxyestrone, but not of 16-hydroxyestrone, increased significantly in the flaxseed group. In this group, the ratio of 2-hydroxyestrone to 16-hydroxyestrone was 100 percent linked with urinary lignan excretion. In the placebo and soy group, researchers observed no correlation. When analyzing the serum hormones and biochemical markers of bone metabolism, researchers found no change.
Researchers concluded supplementation with flaxseed modifies urinary estrogen metabolite excretion significantly more than does supplementation with soy.

Ok, the only SOY I'd possibly intake is soymilk. However, I prefer ricemilk. Any ideas on if ricemilk is good for you?

Rice milk is fine, make sure you get the firtified kind with calcium.
Add flaxseed oil, or Udo's perfiect blend, to shakes and as a salad dressing!!!
One of my favorite ways to have my oil -
2 cups mixed greens
one can tuna
one clove of garlic, pressed
1 tsbp Udo's
salt and pepper
Yumm!

Is flaxseed oil better in one form vs. another? (I take a gelcap supplement daily)
