• Soy-based formula? Neonatal plant estrogen exposure leads to adult infertility in female mice - Science Daily, 5/2/12 - "A paper published May 2 in Biology of Reproduction describes the effects of brief prenatal exposure to plant estrogens on the mouse oviduct, modeling the effects of soy-based baby formula on human infants. The results suggest that exposure to estrogenic chemicals in the womb or during childhood has the potential to affect a woman's fertility as an adult, possibly providing the mechanistic basis for some cases of unexplained female infertility ... part of the National Institutes of Health, previously demonstrated that neonatal exposure to the plant estrogen genistein results in complete infertility in female adult mice. Causes of infertility included failure to ovulate, reduced ability of the oviduct to support embryo development before implantation, and failure of the uterus to support effective implantation of blastocyst-stage embryos ... The team now reports that neonatal exposure to genistein changes the level of immune response in the mouse oviduct, known as mucosal immune response. Some of the immune response genes were altered beginning from the time of genistein treatment, while others were altered much later, when the mouse was in early pregnancy. Together, those changes led to harmfully altered immune responses and to compromised oviduct support for preimplantation embryo development, both of which would likely contribute to infertility ... estrogenic chemical exposure to the female fetus, infant, child, and adolescent all have potential impacts on mucosal immunity in the reproductive tract and, therefore, on adult fertility. The authors present the view that limiting such exposures, including minimizing use of soy-based baby formula, is a step toward maintaining female reproductive health"
• Soy protein alleviates symptoms of fatty liver disease, study suggests - Science Daily, 4/22/12 - "Almost a third of American adults have fatty liver disease, many of them without symptoms ... Obesity is a key risk factor for this condition, which can lead to liver failure ... When fat accumulates in an organ that's not supposed to store fat -- like the liver, that organ's vital function can be dangerously compromised ... Chen compared fat accumulation in the livers of lean and obese rats, which were assigned to either a diet containing casein, a milk-based protein, or a diet containing soy protein, for 17 weeks after weaning ... While diet had no effect on the liver profiles of lean animals, the obese rats that were fed soy showed a 20 percent reduction in triglycerides and overall fat accumulation in the liver"
• Soy beats milk protein for cholesterol improvements: RCT - Nutra USA, 10/22/11 - "Results showed that, compared with carbohydrates, the soy protein was associated with a 3.97 mg/dl reduction in total cholesterol levels, and a 0.12 mg/dl reduction in the ratio of total:HDL cholesterol ... In addition, compared to milk protein, the soy protein was associated with a 1.54 mg/dl increase in HDL cholesterol levels and a 0.14 mg/dl decrease in the ratio of total:HDL cholesterol ... On the other hand, milk protein supplementation was significantly associated with a 1.13 mg/dL decrease in HDL levels, compared to carb supplement ... The effect of milk protein did not confer a significant favorable effect on any lipid measures compared with carbohydrate" - Note:  In addition to homemade yogurt, I been using Silk plus DHA Omega-3 on my cereal.  If you read the ingredients, it's probably not the best for you but it sure tastes good.  The soy adds variety over the milk used to make the yogurt.

• Soya isoflavone consumption in relation to carotid intima-media thickness in Chinese equol excretors aged 40-65 years - Br J Nutr. 2012 Feb 29:1-7 - "Previous studies have suggested that the daidzein metabolite equol rather than daidzein itself contributes to the beneficial effect of soya foods in the prevention of CVD. The aim of the present study is to examine the proportion of equol excretion in Chinese adults and compare plasma lipids and carotid artery intima-media thickness (IMT) between equol excretors and non-excretors, and to evaluate the effect of soya isoflavone intakes on serum lipids and IMT in either equol excretors or non-excretors ... Compared with non-excretors, equol excretors showed significantly lower serum TAG ( - 38.2 (95 % CI - 70.4, - 5.9) %, P = 0.012) and CCA-IMT ( - 4.9 (95 % CI - 9.7, - 0.3) %, P = 0.033). Equol excretors with higher daily isoflavone intakes ( - 5.4 mg/d) had significantly lower IMT ( - 16.2 %, P = 0.035) and tended to have higher HDL-cholesterol (P = 0.055) than did those with lower daily isoflavone intakes (1.5 mg/d), while no association was observed between soya isoflavone intakes and serum lipids or IMT in non-excretors. In conclusion, the benefits of soya isoflavones in preventing CVD may be apparent among equol excretors only"
• Differential Influence of Dietary Soy Intake on the Risk of Breast Cancer Recurrence Related to HER2 Status - Nutr Cancer. 2012 Jan 2 - "Legume intake (mostly from black soybeans) was inversely associated with the risk of breast cancer recurrence in HER2 negative cancer patients (HR: 0.27, 95% CI: 0.13-0.57, P for trend < 0.01), whereas legume intake was positively associated in HER2 positive cancer patients (P for trend = 0.02). In HER2 negative cancer patients, isoflavone was inversely associated with breast cancer recurrence (HR: 0.23, 95% CI: 0.06-0.89; P for trend = 0.01). Total soy intake was not associated with an increased risk of cancer recurrence. In conclusion, overall soy food intake might not affect the risk of cancer recurrence, but high intake of soy isoflavones increased the risk of cancer recurrence in HER2-positive breast cancer patients. However, further research is needed to confirm these results due to the small number of cancer recurrence events"
• Soy intake is associated with lower lung cancer risk: results from a meta-analysis of epidemiologic studies - Am J Clin Nutr. 2011 Nov 9 - "A total of 11 epidemiologic studies that consisted of 8 case-control and 3 prospective cohort studies were included. A significantly inverse association was shown between soy intake and lung cancer with an overall RR of 0.77 (95% CI: 0.65, 0.92). Findings were slightly different when analyses were restricted to 5 high-quality studies (RR: 0.70; 95% CI: 0.45, 0.99). In a subgroup meta-analysis, a statistically significant protective effect of soy consumption was observed in women (RR: 0.79; 95% CI: 0.67, 0.93), never smokers (RR: 0.62; 95% CI: 0.51, 0.76), and Asian populations (RR: 0.86; 95% CI: 0.74, 0.98)"
• Effect of soy and milk protein supplementation on serum lipid levels: a randomized controlled trial - Eur J Clin Nutr. 2011 Sep 28 - "Previous clinical trials have documented that soy protein reduces low-density lipoprotein cholesterol and increases high-density lipoprotein (HDL) cholesterol compared with milk protein ... Compared with carbohydrate, soy protein supplementation was significantly associated with a net change (95% confidence interval (CI)) in total cholesterol and total/HDL cholesterol ratio of -3.97 mg/dl (-7.63 to -0.31, P=0.03) and -0.12 (-0.23 to -0.01, P=0.03), respectively. Compared with milk protein, soy protein supplementation was significantly associated with a net change (95% CI) in HDL and total/HDL cholesterol ratio of 1.54 mg/dl (0.63 to 2.44, P=0.0009) and -0.14 (-0.22 to -0.05, P=0.001), respectively. Compared with carbohydrate, milk protein supplementation was significantly associated with a net change (95% CI) in HDL of -1.13 mg/dl (-2.05 to -0.22, P=0.02). Conclusions: This randomized controlled trial indicates that soy protein, but not milk protein, supplementation improves the lipid profile among healthy individuals"
• Effect of Dietary Protein Supplementation on Blood Pressure: A Randomized, Controlled Trial - Circulation. 2011 Jul 18 - "The trial participants were assigned to take 40 g/d soy protein, milk protein, or carbohydrate supplementation each for 8 weeks in a random order. A 3-week washout period was implemented between the interventions. Three BPs were measured at 2 baseline and 2 termination visits during each of 3 intervention phases with a random-zero sphygmomanometer. Compared with carbohydrate controls, soy protein and milk protein supplementations were significantly associated with -2.0 mm Hg (95% confidence interval -3.2 to -0.7 mm Hg, P=0.002) and -2.3 mm Hg (-3.7 to -1.0 mm Hg, P=0.0007) net changes in systolic BP, respectively. Diastolic BP was also reduced, but this change did not reach statistical significance. There was no significant difference in the BP reductions achieved between soy or milk protein supplementation"
• Alternative Healthy Eating Index and mortality over 18 y of follow-up: results from the Whitehall II cohort - Am J Clin Nutr. 2011 May 25 - "Indexes of diet quality have been shown to be associated with decreased risk of mortality in several countries. It remains unclear if the Alternative Healthy Eating Index (AHEI), designed to provide dietary guidelines to combat major chronic diseases, is related to mortality risk. OBJECTIVE: We aimed to examine the association between adherence to the AHEI and cause-specific mortality over 18 y of follow-up in a British working population. Design: Analyses are based on 7319 participants (mean age: 49.5 y; range: 39-63 y; 30.3% women) from the Whitehall II Study. Cox proportional hazards regression models were performed to analyze associations of the AHEI (scored on the basis of intake of 9 components: vegetables, fruit, nuts and soy, white or red meat, trans fat, polyunsaturated or saturated fat, fiber, multivitamin use, and alcohol) with mortality risk. Results: After potential confounders were controlled for, participants in the top compared with the bottom third of the AHEI score showed 25% lower all-cause mortality [hazard ratio (HR): 0.76; 95% CI: 0.61, 0.95] and >40% lower mortality from cardiovascular disease (CVD; HR: 0.58; 95% CI: 0.37, 0.91). Consumption of nuts and soy and moderate alcohol intake appeared to be the most important independent contributors to decreased mortality risk. The AHEI was not associated with cancer mortality or noncancer/non-CVD mortality. Conclusion: Our findings suggest that the encouragement of adherence to the AHEI dietary recommendations constitutes a valid and clear public health recommendation that would decrease the risk of premature death from CVD"
• Effect of soya protein on blood pressure: a meta-analysis of randomised controlled trials - Br J Nutr. 2011 Feb 23:1-10 - "Meta-analyses of twenty-seven RCT showed a mean decrease of 2·21 mmHg (95 % CI - 4·10, - 0·33; P = 0·021) for systolic BP (SBP) and 1·44 mmHg (95 % CI - 2·56, - 0·31; P = 0·012) for diastolic BP (DBP), comparing the participants in the soya protein group with those in the control group. Soya protein consumption significantly reduced SBP and DBP in both hypertensive and normotensive subjects, and the reductions were markedly greater in hypertensive subjects. Significant and greater BP reductions were also observed in trials using carbohydrate, but not milk products, as the control diet. Meta-regression analyses further revealed a significantly inverse association between pre-treatment BP and the level of BP reductions. In conclusion, soya protein intake, compared with a control diet, significantly reduces both SBP and DBP, but the BP reductions are related to pre-treatment BP levels of subjects and the type of control diet used as comparison"
• Soy food and isoflavone intake and colorectal cancer risk: the Fukuoka Colorectal Cancer Study - Scand J Gastroenterol. 2010 Oct 24 - "Energy-adjusted intakes of soy foods (dry weight) and isoflavones were inversely associated with colorectal cancer risk in men and postmenopausal women, but not in premenopausal women. The multivariate-adjusted OR for the highest versus lowest quintile was 0.65 (95% CI 0.41-1.03, p for trend = 0.03) for soy foods and 0.68 (95% CI 0.42-1.10, p for trend = 0.051) for isoflavones in men. The corresponding values for postmenopausal women were 0.60 (95% CI 0.29-1.25, p for trend = 0.053) and 0.68 (95% CI 0.33-1.40, p for trend = 0.049)"
• Soy isoflavones in conjunction with radiation therapy in patients with prostate cancer - Nutr Cancer. 2010 Oct;62(7):996-1000 - "Soy isoflavones sensitize prostate cancer cells to radiation therapy by inhibiting cell survival pathways activated by radiation. At the same time, soy isoflavones have significant antioxidant and anti-inflammatory activity, which may help prevent the side effects of radiation ... Adverse effects of radiation therapy on bladder, bowel, and sexual function were assessed by a self-administered quality of life questionnaire at 3 and 6 mo. Only 26 and 27 patients returned completed questionnaires at 3 and 6 mo, respectively. At each time point, urinary, bowel, and sexual adverse symptoms induced by radiation therapy were decreased in the soy isoflavone group compared to placebo group. At 3 mo, soy-treated patients had less urinary incontinence, less urgency, and better erectile function as compared to the placebo group. At 6 mo, the symptoms in soy-treated patients were further improved as compared to the placebo group. These patients had less dripping/leakage of urine (7.7% in Group 1 vs. 28.4% in Group 2), less rectal cramping/diarrhea (7.7% vs. 21.4%), and less pain with bowel movements (0% vs. 14.8%) than placebo-treated patients. There was also a higher overall ability to have erections (77% vs. 57.1%). The results suggest that soy isoflavones taken in conjunction with radiation therapy could reduce the urinary, intestinal, and sexual adverse effects in patients with prostate cancer" - See isoflavone products at iHerb.
• Soy food intake and breast cancer survival - JAMA. 2009 Dec 9;302(22):2437-43 - "Soy food intake, as measured by either soy protein or soy isoflavone intake, was inversely associated with mortality and recurrence. The hazard ratio associated with the highest quartile of soy protein intake was 0.71 (95% confidence interval [CI], 0.54-0.92) for total mortality and 0.68 (95% CI, 0.54-0.87) for recurrence compared with the lowest quartile of intake. The multivariate-adjusted 4-year mortality rates were 10.3% and 7.4%, and the 4-year recurrence rates were 11.2% and 8.0%, respectively, for women in the lowest and highest quartiles of soy protein intake. The inverse association was evident among women with either estrogen receptor-positive or -negative breast cancer and was present in both users and nonusers of tamoxifen. CONCLUSION: Among women with breast cancer, soy food consumption was significantly associated with decreased risk of death and recurrence"
