Some menopause symptoms carry with them effects that are not only embarrassing or painful but also fatal. Hypertension has been found to affect a large number of older women, women that may also be suffering other symptoms of menopause. Millions across the world suffer from hypertension and the condition invariably leads to the often fatal coronary heart disease. The study measures the effectiveness of soy in the benefit of menopausal women by introducing Soy into a test sample of women who are suffering from menopause symptoms.

The clinical trial to discover the effect of the competence of soy in reducing this risk involved 60 postmenopausal women. Some of these women were put on a normal Therapeutic Lifestyle Changes diet, which includes a monitored measure of energy, fat and protein. Others in the study were placed on the same diet, with soy protein substituting non-soy protein. Each diet was monitored for a length of 8 weeks.

In order for the study to be fair and accurate exclusions amongst the women included: those that were current smokers or smoked last year and those that consumed more than 21 alcoholic drinks per week. The conclusions of the study showed varying results in regards carbohydrate levels between normotensive and hypertensive women taking soy. In regards saturated fat however, women in the soy group showed significantly lower levels in contrast to the non soy diet. In regards the creation of equol in the body, soy has been clinically proven to increase the effectiveness of reducing bone loss. Women taking soy supplements and found capable of producing equol in the body were shown to be able to increase lumbar bone density by 2.4%.

Testing in regards soy and menopause symptoms has shown that the levels of polyunsaturated fat, protein and isoflavone were higher. While the levels of carbohydrate was lower in the soy diet for normotensive women. The results for hypertensive women were more consistent, with polysaturated fat, protein and carbohydrate levels all higher on the soy diet than on the normal diet.
