"A 'toxic substance] is implicated 'in contributing to].... Parkinson's Disease and chronic alcoholism. 'It is.... found in certain beverages and foodstuffs, including soy sauce, beer and bananas.]"

In a comparison in the post-menopausal period, a report showed that soy phytoestrogens and estrogen replacement therapy in subjects with atherosclerosis showed equal benefits. In another study, soy isoflavones showed no benefit in thyroid conditions. Others showed a cause of these conditions to be a deficiency of iodine.

"These data suggest that consumption of soy products have a protective effect against hot flashes."
Significantly lower intake of soy products were found to be 'associated with] patients with osteoporosis.

"It is concluded that treatment with phytosterols 'rich content in soybeans] reduces the growth and metastasis 'spreading] of prostate cancer cells by reducing tumor adhesion, migration and invasion."

"Lyn 'tyrosine kinase]....blocks the export of p53 complex." P53 is a tumor-suppressor gene. So tyrosine kinase indirectly enhances tumor growth. Genistein in soy reduces tyrosine kinase, thus genistein in effect helps the body to kill tumor cells.

Another study revealed a transient rise in epidermal growth factor 1 after genistein treatment for bladder cancer. This is not good. Fortunately, the effect is short-lived.

"Genistein prevents 'the increased self-oxidation of glucose] by.... low density lipoprotein 'LDL, the potentially harmful cholesterol carrier in the blood.]

"These data suggest a protective role for dietary soy intake against CVD 'cardiovascular disease] in post-menopausal women."

"The present study showed a beneficial effect {of soy protein extract] against kidney disease."

"Genistein's effect on 'certain T cells] which are critical 'in immune defense], suggest it may impair immune function."
