Modern studies have proved soy on health in many ways useful, if similar to the role of estrogen. Cite here the two most recent role.
United Kingdom, "Journal of Nutrition" Some people think that the benefit of soy and heart disease prevention and treatment of diabetic nephropathy. They studied 14 cases of 53 ~ 73-year-old diabetic nephropathy in type 2 diabetic male patients. A group to the purified soybean protein powder, another group of white powder to the meat of animals are seasoned with vanilla, mixed with the original beverage or food to eat.
The outcome of patients who eat soy protein protein in urine volume reduced by about 10%, indicating an improvement in diabetic nephropathy, and to eat animal protein in urine of patients with increased protein. Eating soy protein and blood in patients with high-density lipoprotein (HDL, also known as the "good cholesterol") increased by 4%. And HDL is easy to reduce complications of cardiovascular disease.
Diabetic nephropathy at an early stage of protein should be added. The researchers had anticipated that after the soy protein supplement protein in urine is not increased, but did not expect to reduce, and increase HDL blood also reduced the chance of cardiovascular disease complications. Therefore appears to be should eat less meat soybeans.
The United Kingdom "Urology" magazine in Australia, experts believe that soy can prevent prostate cancer. Because the incidence of prostate cancer with androgen-related, and generally that contain soy phytoestrogens (ie, the role of estrogen similar to the plant components), may be offset by the role of androgen. They diagnosed 29 cases of prostate cancer patients prepared for surgery were divided into 3 groups: Group soybeans, soybean plus flaxseed group (high phytoestrogen) and the wheat group (low phytoestrogen). The first two groups each with 50 grams of soybean meal or cooked together with linseed powder made of 20 grams of bread daily doses for patients. Determination of the beginning and the pre-surgery blood prostate-specific antigen (PSA), free PSA, testosterone, sex hormone-binding globulin, free androgen index and other indicators of dihydrotestosterone. The results showed that the total group of soybean meal and free PSA / total PSA ratio than those in the control group improved significantly.
Previous epidemiological studies that there are plenty of men Phytoestrogen the risk of prostate cancer less. In this study, PSA is an important diagnostic indicator of prostate cancer, it reduced the prostate cancer that has improved. Therefore, the work of epidemiological studies and the results were consistent.
Of course, these two studies is only preliminary, because the number of cases is not more research remains to be further expanded. However, moderate use of soy, no harm beneficial, can be as therapeutic.
