2. Nutrients and Phyto-
chemicals in Soybean
Phytochemicals
• phytosterols,
• lecithins,
• saponins, and
• phenolic acids
• Anticarcinogens-
isoflavones
Nutrients
• Protein
• Fat
• Complex
carbohydrates
• Dietary fibre
3. How does it help
Protein
consumption of soy protein selectively decreases
total and LDL (bad) cholesterol and maintains
HDL (good) cholesterol in individuals with
elevated normal blood cholesterol levels. The
United States Food and Drug Administration
and American Heart Association issued a
health claim for soy protein that states,
"consumption of 25gms of soy protein per day
with a diet containing low in saturated fat may
lower the risk of heart diseases".
4. How does it help
Oil
it has zero trans fat, is low in saturated fat ("the
bad fat") and high in poly- and mono-
saturated fat ("the good fats").
This combination causes the reduction of blood
cholesterol and lowers the risk of heart
disease.
Soybean oil features omega-3 fatty acids and is
the primary commercial source for Vitamin E,
which defends against forms of cell damage
ranging from cancers, heart disease and
cataracts to premature aging and arthritis.
5. How does it help
Anticarcinogens
Human epidemiological studies suggest
that as little as one serving of soy foods
each day may be protective against
many types of cancer, including cancers
of the lung, colon, rectum, stomach,
prostate and breast.
6. How does it help
Menopause
Soybean is considered as a natural
alternate for hormone replacement
therapy for women who are in
menopause. Soy foods are a rich
source of phytoestrogens, which may
help compensate for the lack of natural
estrogen production.
7. How does it help
Osteoporosis
soy protein exhibits less calcium leaching
effects. The isoflavones found in
soybeans may also directly stop bone
deterioration
8. How does it help
Obesity
A study published in the August 2003
issue of Endocrinology suggests active
isoflavone compounds found in soy,
specifically, genistein, may help us stay
lean by causing us to produce fewer
and smaller fat cells.
9. How does it help
Blood Pressure
A study published in the February 2004 issue of
the Journal of the American College of
Nutrition has investigated the effects of soy
protein and soy isoflavones on blood
pressure and cholesterol levels found that
men consuming soy in their diet were found
to have significant reductions in both diastolic
and systolic blood pressure.
10. How does it help
Diabetes
Soybeans can be very beneficial is diabetes,
particularly type 2 diabetes. The protein and
fiber in soybeans can also prevent high blood
sugar levels and help in keeping blood sugar
levels under control. In addition, soybeans
have been shown to lower high triglyceride
levels. Triglyceride levels tend to be high in
diabetic patients, and high triglyceride levels
are another factor of diabetics' increased risk
for heart disease.
11. How does it help
Diabetes-related Kidney and Heart
Disease
Soy protein can help protect diabetics'
hearts and kidneys from damage
caused by the disease. Specifically, the
patients' urinary urea nitrogen and
proteinuria were found much lower on
the soy protein diet.
