QUINOA SUPERFOOD
Description
Because
quinoa is typically consumed in the same way as the cereal grasses (wheat,
oats, barley, and rye), we group it together with those foods on our website.
However, quinoa is not a cereal grass at all, but rather a member of the same
food family that contains spinach, Swiss chard, and beets. Many researchers
refer to quinoa as a "pseudocereal." This term is typically used to
describe foods that are not grasses but can still be easily ground into flour.
The scientific name for quinoa is Chenopodium quinoa.
History
The
history of quinoa is clearly rooted in South America, in the Andes region that
is currently divided up between the countries of Argentina, Bolivia, Chile,
Colombia, Ecuador, and Peru. Along with maize, quinoa was one of the two
mainstay foods for the Inca Empire that had its start around 1200 AD. As
previously mentioned in the Description section, quinoa was a food that could
survive in a wide variety of growing conditions. Along with its unusual
nutrient richness, its adaptability helped it gain popularity among the Incas
for hundreds and hundreds of years.
How to Select and Store
Quinoa
is generally available in prepackaged containers as well as bulk bins. Just as
with any other food that you may purchase in the bulk section, make sure that
the bins containing the quinoa are covered and that the store has a good
product turnover so as to ensure its maximal freshness. Whether purchasing
quinoa in bulk or in a packaged container, make sure that there is no evidence
of moisture. When deciding upon the amount to purchase, remember that quinoa
expands during the cooking process to several times its original size. If you
cannot find it in your local supermarket, look for it at natural foods stores,
which usually carry it.
Nutritional Profile
Quinoa
is food of high protein quality and is typically regarded as an adequate source
of all essential amino acids, including lysine and isoleucine. It provides a
variety of antioxidant phytonutrients, including ferulic, coumaric,
hydroxybenzoic, and vanillic acid. Antioxidant flavonoids including quercetin
and kaempferol are also especially plentiful in quinoa. Anti-inflammatory
polysaccharides in quinoa include arabinans and rhamnogalacturonans. Many
members of the vitamin E tocopherol family are provided by quinoa, including
important amounts of gamma-tocopherol. Quinoa is a very good source of
manganese. It is also a good source of phosphorus, copper, magnesium, dietary
fiber, folate, and zinc.
Health Benefits
Overall
Nutrient Richness
Perhaps the most striking health benefit provided by quinoa is its
overall nutrient richness. When the nutrient composition of this food is
analyzed in depth, the results are unusual and striking. While quinoa can be
eaten in the same way as a grain, or ground into flour like is so commonly done
with grains, it lacks some important nutritional shortcomings of grains.
One of the shortcomings overcome by quinoa involves its protein content.
Most grains are considered to be inadequate as total protein sources because
they lack adequate amounts of the amino acids lysine and isoleucine. The
relatively low level of both lysine and isoleucine in the protein of grains is
what causes these amino acids to be considered as the limiting amino acids
(LAAs) in grains. In other words, these LAAs prevent grains from serving as
complete protein sources in our diet. By contrast, quinoa has significantly
greater amounts of both lysine and isoleucine (especially lysine), and these
greater amounts of lysine and isoleucine allow the protein in quinoa to serve
as a complete protein source.
Anti-Inflammatory Benefits
Most of the
quinoa studies that we've seen in this area have been animal studies. However,
we believe that the preliminary indications for humans are very promising.
Research has shown the ability of daily quinoa intake to lower levels of
inflammation in fat (adipose) tissue in rats and in the linings of their
intestine as well.
Gluten
free
Gluten-free diets are
recommended for people with Celiac
disease,
a severe gluten intolerance. Though the scientific community is still
debating the
benefits of gluten-free diets for people who do not have Celiac disease, plenty
of Americans have jumped on the bandwagon. Medical
News Today estimates
that approximately 1.6 million follow a gluten-free diet without having been
diagnosed with the disease.

Lowering cholesterol
Quinoa’s good fiber content
can aid in lowering cholesterol levels, according to Toups. Fiber aids in
digestion, which requires bile acids, which are made partly with cholesterol.
As your digestion improves, the liver pulls cholesterol from the blood to
create more bile acid, thereby reducing the amount of LDL, the
bad cholesterol.
A study published in the journal Plant
Foods for Human Nutrition found that rats that had consumed a high
level of fructose and were then fed a quinoa diet reduced their LDL cholesterol
by 57 percent.


Heart health
Lowering LDL cholesterol is
good for your heart, but quinoa can benefit your ticker in other ways as well.
A study published in the Journal of
Food Lipids noted
that quinoa seeds possess many of the dietary flavonoids "shown to
inversely correlate with mortality from heart disease."
Diabetes and hypertension
"Quinoa has also been
studied for its role in diabetes management and hypertension," said Toups.
Commenting on a study published in the Journal of
Medicinal Food,
she said, "Brazilian scientists researched 10 traditional Peruvian grains
and legumes for their potential in managing the early stages of Type 2
diabetes.
They found that quinoa was especially rich in an antioxidant called quercetin
and that quinoa had the highest overall antioxidant activity (86 percent) of
all 10 foods studied." She added that the study led researchers to
conclude that quinoa, kañiwa (quinoa’s cousin) and other traditional crops from
the Peruvian Andes have potential in helping researchers to develop effective
dietary strategies for managing Type 2 diabetes and associated hypertension.
Quinoa risks
There are
a few health risks associated with eating quinoa. Quinoa seeds are coated with
saponins, which are chemicals designed to protect plants from diseases caused
by fungi, bacteria and viruses, according to the Environmental Protection Agency. Saponins can have a bitter, soapy taste, so
quinoa should be rinsed thoroughly in cold water before it is cooked.
Quinoa cooks faster than most whole grains, taking
only 12 to 15 minutes, according to Toups. This makes quinoa "an easy
grain for busy families and individuals to add to their weekly rotation,"
she said. Furthermore, "Unlike some grains that tend to dry out when
cooled, quinoa maintains a pleasant, chewy texture when served warm, chilled or
at room temperature."
Protein
in Quinoa:
One
of the best reasons to enjoy quinoa is because it has a high-protein content,
which makes it a great cholesterol-free and low-fat source of protein for vegetarians and
vegans. According to the USDA nutrient database, 1
cup of cooked quinoa (185 g) contains 8.14 grams of protein.
