| Soy,
A Perfect Gift From Nature To Our Health
|
| Soy has been consumed by Asians for centuries.
As industrialized nations pay more attention to healthy eating,
soy has received tremendous attention from research scientists
around the world. The abundance of scientific evidence shows
that soy truly is a remarkable food. |

| With a PDCAAS (Protein Digestibility Corrected
Amino Acid Score) of 1.0, soy protein quality equals to those
of proteins from meat, dairy, and egg white. One gram of soy
protein can replace one gram of animal protein. Unlike animal
protein sources, soy contains NO cholesterol and a very low
amount of saturated fat. |

| Other
Health Benefits |
Scientific evidences show that soy foods provide
much more than just protein to our health.
Soy and Coronary Heart Disease:
Regular consumption of soy protein (25g per day) together
with a diet that is low in cholesterol and saturated fat can
significantly lower your cholesterol and reduce the risk of
coronary heart disease. In 1999, the Food and Drug Administration
approved this health claim to foods that contains at least
6.25g soy protein per serving.
Soy and Cancers:
Many studies showed isoflavones found at high level in soy
products could reduce the risk of breast cancer and prostate
cancer. Researchers found that Asian women have a much lower
risk of breast cancers and a much higher intake of isoflavones
in their diets compared to western women. Results also showed
that isoflavones could significantly reduce the rise of PSA
in prostate cancer patients and lower incidence of prostate
cancer in Asian men was associated with higher concentration
of isoflavones and their metabolic intermediates in their
prostate fluid.
The following table shows the isoflavones content in various
soy foods:

In addition to its benefits on coronary heart
disease, breast cancer and prostate cancer, regular consumption
of soy foods have been associated with other health benefits,
such as improving women’s menopause symptoms, and improving cognitive
functions.
Truly, soy is a perfect gift from nature to our health. |
