On the other hand, soy peptides and isoflavones
are biodegradable, environmentally friendly and non-toxic.
genistein, daidzein, equol were measured in 24 h urine samples.
There is growing interest in using soy isoflavones
in diseases related to metabolic syndrome.
The major isoflavones
include genistin, daidzin, glycitin, equol, and biochanin A and, in particular, genistein is the most widely investigated isoflavon [Figure 1].
The 66mg of isoflavone
that we use in this study is equivalent to eating an oriental diet, which is rich in soy foods.
Conclusion Soy isoflavones
supplementation 160 mg/day can lower total AV lesion.
Muscle and joint pain improved significantly for both the 10 and 20 mg doses of S-equol compared with the soy isoflavones
The levels of isoflavones
in soybeans grains vary with the stage of development.
Researchers assigned 182 women (all had been menopausal for no more than rive years) to take either 200 milligrams of a soy isoflavone
tablet or a placebo every day.
However, given that prolonged oestrogen treatment may increase the risk of endometrial and breast cancers, the structural similarity between oestrogen and soy isoflavones
raises the question of whether they too might pose some risk.
Research over the past 10 years has reported mixed results due to varying study designs and soy preparations, but the literature overall still supports the conclusion that soy protein with isoflavones
can decrease blood levels of LDL cholesterol (Zhan and Ho 2005).
There is a concern, however, regarding the harmful effects of soy isoflavones
on thyroid function.
