Fermentation increases the digestibility of soy (especially its proteins), nutrient absorption from soy (including absorption of phytonutrient isoflavones
like genistein and daidzein), and the concentration of bioactive peptides (formed during the breakdown of soy proteins during fermentation).

It aims to establish whether high doses of the
treatment Genistein Aglycone is effective in people with Sanfilippo Disease.
«The dose potency of
genistein appears to be approximately 1/10 that of E2 [estradiol - 17 beta] in this system.
And Dr. Claude Hughes reported that rats born to mothers that
consumed genistein (an estrogen - like compound found in soy) had decreased birth weight and earlier onset of puberty compared to controls.
Perinatal genistein exposure resulted in transient and lasting alterations in masculinization of the reproductive system.
Second, they can inhibit thyroid function due to their high levels of goitrogens and the isoflavone
genistein which can be antagonistic to thyroid hormone.
The levels of
genistein used in these experiments are comparable to those found in infant formula based on soy.»
Some of the other flavonoids that have a mild inhibitory effect on CYP's
include genistein, diadzein and equol from soy and the aflavins from black tea.
Tofu is a weight loss friendly food thanks to one
ingredient genistein — compound which suppresses appetite.
A previous NIEHS study showed that newborn mice
given genistein grew up to experience irregular menstrual cycles, erratic ovulation and other problems indicative of infertility.
In recent studies, rats fed the isoflavone
genistein exhibited pathological changes in the colon23 and rats fed soy - based chow had reduced growth and an increase in gastrointestinal problems.40
This occurred even though the soy isoflavones were so well absorbed that blood levels of the
isolflavone genistein rose from 4.76 ng / mL to 37.67 ng / mL over the course of the study.
In various studies, green tea polyphenols, catechins, and
genistein supplements were associated with better protection against sun [1].
Nakamura Y, Yogosawa S, Izutani Y et al.. A combination of indol -3-carbinol and

Metabolism of the soy isoflavones daidzein and
genistein by fungi used in the preparation of various fermented soybean foods.
Research out of the University of Maryland and reported in the Journal of Agriculture and Food Chemistry found that quail feed supplemented with the soy isoflavone
genistein ended up in the egg yolk but not the egg white.
Soy products, including Soy Protein, have naturally occurring phytoestrogens and beneficial proteins such
as Genistein and Daidzein.
Male rats exposed to
genistein also have lower testosterone concentrations in adulthood.
It is thought that
Genistein Aglycone works by blocking the production of heparan sulphate and associated damage to the cells.
A US study published last year, demonstrated the safety of high doses of
Genistein Alygone in patients with Sanfilippo Disease4.
Finally the soy isoflavone
genistein reduces DNA synthesis in the brain, reducing the birth of new brain cells and promoting apoptosis and cell death.
Newbold primarily looked at the effects of the synthetic estrogen DES on the development and growth of rats; but she also examined other sources of endocrine disruption, including the
phytoestrogens genistein and diadzen in soy.
i - cool health supplement is enriched with the
