Because of all the health benefits of spinach, it ranks high among
green leafy vegetables. Believed to have originated in the Arab
countries and cultivated by the Persians (Iranians) about 2000 years
ago, spinach (spinacia
oleracea) was taken to Spain by the Moors, and from there it
spread
to other countries. The US and the Netherlands are the largest growers
of spinach today.
The word spinach comes from the Spanish word hispania.
Spinach, palak,
or palakoora, as it's known in some Indian
languages, is very popular in Indian cooking. While spinach is commonly
used in salads, soups, and quiches in the US, in India, spinach is
used in curries, soups, breads, appetizers, and raitas.
Spinach and Health
Quick Facts
Spinach is rich in
essential amino acids, iron, calcium, vitamin A, and folic acid. It is
the most inexpensive source of protein, providing as much protein as
meat, fish, eggs, chicken do in the same quantity. Spinach is also an
excellent source of fiber.
The iron in spinach makes it an excellent vegetable for those suffering
from anemia, menopause, or chronic fatigue syndrome.
Spinach is rich in B-complex
vitamins which protect the cells from
mutating into cancerous cells.
Spinach is also rich in lutein which helps protect against eye ailments
such as macular degeneration and cataracts, the leading causes of
blindness in old age. (Lutein
and zeaxanthine
also give spinach and
other greens their green color.)
The vitamin A, vitamin C, magnesium, and riboflavin help reduce
inflammation associated with arthritis, asthma, heart disease.
Studies show that the vitamin A and vitamin C in spinach may help
prevent atherosclerosis and diabetic heart disease by reducing free
radicals and preventing oxidation of cholesterol that would otherwise
stick to the walls of the blood vessels.
The folic
acid in spinach helps prevent buildup of homocysteine, a
substance that can lead to heart attacks.
Magnesium in spinach can help reduce high blood pressure and reduce the
risk of heart disease.
Spinach has a cooling and soothing effect on the body. It also has a
laxative effect because of the fiber. Spinach juice is recommended by
experts to treat constipation. Spinach juice combined with fresh
coconut water is also recommended by experts as a diuretic for treating
urinary disorders such as cystitis and nephritis.
Spinach is a rich source of calcium and other alkaline elements which
preserve the alkalinity of the blood, thereby preventing chronic
diseases such as acidosis
caused by too much acid in the blood.
The folic acid in spinach makes it very valuable during pregnancy as it
helps in the healthy development of the fetus and reduces the risk of
abortion and accidental hemorrhage. Spinach provides a lot of nutrition
to lactating mothers and improves the quality of the milk.
Cooking Tips
If buying fresh, loose spinach (rather than
pre-washed and bagged, frozen, or canned), make sure the leaves are
green and crisp. Buy spinach bunches that are dry, as any moisture will
cause them to spoil quickly. Store in a plastic bag in the refrigerator
to keep spinach fresh for about a week.
Before using, chop off the thicker part of the stems,
and wash in several changes of water to get rid of sand and dirt.
(Place the leaves in a large bowl of water and let sit for a few
seconds for the dirt and sand to settle at the bottom, remove the
leaves, and repeat until the water is clear.)
While most of the time it's safe to eat spinach raw,
it's better to cook it (blanch, steam, or saute) to get rid of bacteria
such as E. Coli.
To
prevent loss of nutrients, cook the leaves on
medium heat, and blanch or steam the leaves. Place the leaves in a pan
on low-medium heat, and cover and cook until tender. No water is needed
as spinach contains a lot of water like other greens and release water
as they cook.
To improve iron absorption, combine spinach with
vegetables and fruits rich in vitamin C such as citrus (lime/lemon,
oranges) and tomatoes.
