Soy has become quite the popular kid on the block!
Soy-based foods such as soymilk, tofu, miso, tempeh, and
edamame aren't just limited to health stores anymore.
These days you find them all over in supermarkets, coffee
shops, and restaurants in many different forms.
It's a protein-packed way to replace meat and dairy products
for vegans, vegetarians, and those who are lactose intolerant.
Are Soy Foods Healthy?
With so much conflicting and confusing information out
there, you may wonder if soy is actually good for you or not?
On the one hand, you hear it's rich in nutrients and
powerful minerals. Diets containing it appear to have many health benefits.
It can lower blood sugar levels, improve heart health,
reduce menopause symptoms, and even lower the risk of certain cancers.
But on the other hand, headlines about the negative effect
of soy pop up all over the internet.
"Soy increase the risk of breast cancer."
"Soy hinders your thyroid function," or maybe
something like
"Increase your chances of getting pregnant by avoiding
soy."
So, which is true? It's all a bit confusing, we know!
As with all foods, the research on soy is still ongoing. But
in recent years, it has been discovered that moderate consumption of minimally
processed soy foods (more on what those are later) does indeed offer some
benefits.
The Benefits Of Soy
Soy contains phytoestrogens, a hormone-like substance that
mimics estrogen, a powerful antioxidant and often associated with many health
benefits.
Soy foods are also rich in B vitamins, potassium, magnesium,
fiber, and high-quality protein. Soy protein is one of the few plant-based
proteins considered a complete protein. It contains all nine essential amino
acids that the body cannot make and must be obtained from the diet.
Not only is soy high in protein, it is also low in
saturated fat, making it a great alternative to animal proteins which are often
high in fats.
Protect Against Heart Disease
Eating a diet rich in soy products is linked with a lower
incidence of cardiovascular disease, including strokes and heart attacks.
Soy isoflavones appear to reduce inflammation in blood
vessels and improve their elasticity — two key factors believed to protect the
heart.
People with existing risk factors for cardiovascular
disease, including high blood pressure, cholesterol, obesity, and type 2
diabetes, seem to be among those who might benefit most from soy-based diets.
Lowers LDL (Bad) Cholesterol
Levels
Many studies suggest that diets that include soy foods may
help lower LDL (bad) cholesterol and raise HDL (good) cholesterol.
One study concluded that a median intake of 25 grams of soy
protein per day might help reduce LDL (bad) cholesterol levels by around 3%.
Lowers Blood Pressure
Soybeans and soy foods are generally rich in arginine, an
amino acid believed to help regulate blood pressure levels.
Soybeans are also rich in isoflavones, a compound
believed to offer blood-pressure-lowering benefits.
Reduces The Risk Of Certain
Cancers
Soy-rich diets may help lower the risk of certain types of
cancer, but more research is needed on this subject.
One study indicated that a diet high in soy was
associated with a reduced risk of recurrence of breast cancer.
Other studies suggest that high intakes of soy isoflavones
may lower the risk of endometrial cancer by around 19%.
Soy-rich diets may be associated with a 7% lower risk for
digestive tract cancers and an up to 12% lower risk of colon cancer. Men eating
soy-rich diets may benefit from a lower risk of prostate cancer.
It Could Assist With
Infertility
Soy actually appears to be beneficial for fertility.
Moderate soy consumption won't pose a problem in productive
health.
Women undergoing IVF are more likely to get pregnant if they
consume unprocessed soy.
Furthermore, no differences were found in reproductive
health between adults who consumed soy formula as infants compared to those who
consumed cow's milk formula as babies.
But don't overdo it. Daily consumption of over 100mg of soy
isoflavones (the equivalent of 6-ounces uncooked tempeh or 16 cups of soy milk)
can lead to impaired ovarian function.
May Help With Menopause
Symptoms
As soy is rich in phytoestrogens, or plant estrogens, they
can bind to estrogen receptors in the body.
Menopause causes a woman's estrogen levels to naturally
decrease, causing unpleasant symptoms, such as tiredness, vaginal dryness, and
hot flashes.
By binding to estrogen receptors in the body, soy
isoflavones (or phytoestrogens) help reduce the severity of these
symptoms.
It can also help with joint pain, depression, and
irritability, all common symptoms of menopause.
The Best Soy Products To Eat
When it comes to choosing soy products, quality is the most
important.
The best is to choose non-processed soy products such as
tofu and edamame beans.
Processed soy products like soy burgers, sausages, and
cheeses contain soy protein that has been heavily processed and stripped from
its nutrients. They also often contain added sodium, fats, preservatives, and
sugars.
These convenient soy foods are not even ok to enjoy
occasionally as a treat.
Here are some of the best soy products to choose.
Soy Products
Edamame – Unprocessed raw green soybeans high in
fiber and protein. You will find these in the frozen section at the grocery
store.
Soybeans – Dry hard beans that you need to soak
overnight and then cook for three to four hours. They are excellent to use in
stews and soups.
Soynut Butter – Made from whole roasted soynuts that
are ground fine and blended with soybean oil.
Soy Milk – Made by cooking the creamy milk of crushed
soybeans. Sweeteners, nutrients, and plant-based thickening agents are often
added to give soy milk a consistency similar to cow's milk.
Soy Dairy Products – Cheese, Cream cheese, sour
cream, yogurt, and frozen desserts like ice cream are all based on soy milk as
the primary ingredient.
Soybean Oil – A healthy oil with a neutral flavor
that contains no cholesterol and has good omega-3 fats.
Soy Flour – Used as an alternative to all-purpose
flours.
Soy Nuts – A crunchy snack made from mature soybeans
that have been soaked in water, drained, and dry-roasted with just a little bit
of salt.
Tofu – Tofu is one of the more known soy products and
meat replacements. It is made by stirring a thickener into warm soy milk to
make a curd-like consistency. It comes in soft, firm, or extra-firm varieties.
Moderate Soy Consumption Is
Not Bad For You
As you can see, soy has many benefits and far outweigh
the minimal risks it poses.
You also need to consume a reasonably large amount before
the negative effects become significant.
As with all things in life, moderation is key and the
quality of your food. Limit processed soy products and choose the most natural
form of soy.
But we would say it is safe to say that soy is a joy!! So go
ahead and order that tofu.
