at long last!!!! i finaly was able to re enter the forum. something like an issue with the browser or something he he.
soya has long been an ally of the health services, first for being a pure and clean source of protein and with its numerous benefits. but of course as a marketing ploy some people would launch a lot of "true" stories and more often than not.... altered studies to show that it is "harmful". experienced readers should look also at the personal history of these supposed "stories" because they often omit something. e.g. family history of uterine growths, abnormal dieting habits, career related exposure to carcinogens.... the list goes on... in the long run it would be up to the diligent readers who will find out which of these supposed claims are true or not... long live the book worms hehe

[glow=Yellow,2,300]Galit lang talaga nagsulat ng article na yan about soya being bad.
The fact that she wrote "soya is a toxic by product of vegetable OIL industry" is a give away that this woman knows nothing but telling lies because there's no oil in soya unless you want to sqeeze it with tons of pressure.
Estrogen in soya?? What the?? If that's the case queers would be recomended to consume this product to enhance their feminine features! I'm not a chemist, but how would estrogen survive temperatures of at least 130 degrees celsius (required temperature for processing soya)?
Please read this carefully before judging:
What is it? Soya, a staple food in many Asian countries, contains valuable constituents, including protein, isoflavones, saponins, and phytosterols. Soya protein provides essential amino acids. When eaten with rice, soya provides protein comparable with that found in animal products. Soya is low in fat and cholesterol-free.
The isoflavones in soya, primarily genistein and daidzein, have been well researched by scientists for their antioxidant and phytoestrogenic properties.1 Saponins enhance immune function and bind to cholesterol to limit its absorption in the intestine. Phytosterols and other components of soya have been reported to lower cholesterol levels.
The soya isoflavone genistein has been reported to inhibit angiogenesis,2 the growth of new blood vessels that, when abnormal, can contribute to the development of cancer. Soya isoflavones have also been shown to inhibit 5 alpha-reductase,3 the enzyme that activates testosterone in the prostate gland and other tissues. 5 Alpha-reductase inhibition represents a potentially effective therapeutic approach to benign prostate enlargement and male pattern baldness.
Isoflavones may reduce the risk of hormone-dependent cancers, such as breast and prostate cancer, as well as other cancers. One study of soya research found that 65% of 26 animal-based cancer studies showed a protective effect of soya or soya isoflavones.4 Human research also suggests a protective role of soya against cancer,5 6 but the data are currently insufficient to form any solid conclusions.7
A review of 38 different studies revealed that soya consumption reduced cholesterol levels in 89% of the studies. A meta-analysis of these studies indicated that eating soya resulted, on average, in a cholesterol reduction of 23 mg per deciliter.8 Exactly how soya lowers cholesterol remains in debate,9 though isoflavones appear to be one key component.10
The mild oestrogenic activity of soya isoflavones may ease menopause symptoms for some women, without creating oestrogen-related problems. In one double-blind trial, supplementation with 60 grams of soya protein per day for 12 weeks led to a 45% decrease in the number of hot flushes, compared with a 30% reduction in the placebo group, a statistically significant difference.11 In addition, soya may help regulate hormone levels in premenopausal women.12
Soya may also be beneficial in preventing osteoporosis. Isoflavones from soya have protected against bone loss in animal studies.13 In a double-blind study of postmenopausal women, supplementation with 40 grams of soya protein powder per day (containing 90 mg of isoflavones per day) protected against bone mineral loss in the spine.14 Although the use of soya in the prevention of osteoporosis looks hopeful, no long-term human studies have examined the effects of soya or soya-derived isoflavones on bone density or fracture risk.
Where is it found? Relatively large amounts of isoflavones are present in whole soybeans, roasted soya nuts, tofu, tempeh, soya milk, meat substitutes, soya flour, and some soya protein isolates. In addition, the isoflavones present in soya are available as supplements, in capsules or tablets [/glow]
