Squash in the same
family as pumpkin and acorn squash. Squash is low in calories but rich in
vitamins, minerals and dietary fiber--nutrients which promote optimal health.
In addition, this vegetable may reduce your risk of developing lung cancer, and
it fights heart disease coupled with its effective fight against birth defects.
Nutrient-Dense Food
Nutrient-Dense Food
One
cup of squash cubes, baked, offers only 82 calories, 0 g fat, 2 g protein, 22 g
carbohydrates and nearly 5 g dietary fiber. Butternut squash is an outstanding
source of vitamin A, meeting over 100 percent of the Recommended Daily Value,
or DV, in a 1 cup serving; over 30 percent of the DV for vitamin C; and is a
good food source of vitamins E, B1, B3, B6 and folate. It also contains
appreciable amounts of the minerals potassium, magnesium and manganese.
Vitamin
A is important for healthy eyesight and reproductive health and, along with
vitamins C and E, supports immune system function. The B vitamins serve many
functions in the human body, such as acting as co-enzymes in energy metabolism
and supporting nervous system function. Potassium and magnesium help lower
blood pressure and manganese is also involved in the metabolism of
carbohydrates, fats and proteins and helps nourish the nerves and brain.
Folate in Squash Protects Against Birth Defects
Squash
contains folate, which has been shown to reduce the incidence of neural tube
defects and other birth defects when taken by women before and during
pregnancy. A cup of Squash contains 15 percent of the recommended daily
allowance of folate. Folate also works to prevent heart attacks by working
against elements that break down blood vessel structures in your body. There is
also a correlation between folate intake and reduced incidences of colon cancer.
Reduces Lung Cancer
Vitamin
A precursors known as carotenoids offer health benefits. The predominant
carotenoid in winter squash is beta-cryptoxanthin, and is responsible for its
orange-red color. Other fruits and vegetables rich in beta-cryptoxanthin are
pumpkins, papayas and red bell peppers. This carotenoid may reduce your risk of
developing lung cancer. Researchers measured lifestyle and dietary data in over
60,000 Chinese adults for a study that was published the September 2003 issue
of "Cancer Epidemiology, Biomarkers and Prevention." They discovered
that those eating the most beta-crytpoxanthin-rich foods enjoyed a 27 percent
reduction in lung cancer risk. Current smokers had an even more significant
risk reduction; a 37 percent lower risk of lung cancer compared to smokers who
ate the least of these beta-crytpoxanthin-rich foods.
Benefits Heart Health
Nutrients
in Squash, including vitamins A and C, maganese and magnesium, work together in
your body to help protect against some forms of heart disease. Magnesium is
indicated as a helpful agent in the prevention of strokes and works with
potassium to maintain healthy blood pressure levels. The folate in squash also
protects against heart attacks by helping to neutralize dangerous levels of
harmful homocysteine in the body. A healthy intake of fiber, present in squash,
is associated with lower rates heart disease.
Butternut
squash promotes heart health in two ways. First, it is particularly rich in
dietary fiber, providing 5 g per cup, cooked. According to the U.S. Department
of Agriculture Dietary Guidelines for Americans, diets rich in dietary fiber
decrease the risk of coronary heart disease by lowering total blood cholesterol
levels. Butternut squash is also is rich in folate, a B vitamin that, among
other functions, is needed to break down a toxic metabolic byproduct in the
body, known as homocysteine, according to the American Heart Association. A
high level of homocysteine in the bloodstream is associated with an increased
risk for heart attack and stroke because it directly damages blood vessel
walls.
Squash
Improves Lung Health
Researchers
have found that a vitamin A deficiency, caused by a carcinogen in cigarette
smoke, can contribute or lead to the debilitating disease of emphysema. Squash,
as well as sweet potatoes, contain high levels of vitamin A that may help
protect against emphysema. Also, there is a correlation between eating foods
high in the carotenoid beta-cryptoxanthin, and decreased incidence of lung
cancer. These findings may explain why some smokers don't get lung cancer while
others suffer from lung problems and die of cancer. While quitting smoking is
ideal, a diet rich in vitamin A and beta-cryptoxanthin may protect lung health
if a person unable to quit or is still exposed to cigarette smoke.
Eating Squash Helps Fight Diseases
Squash
is a good food for those suffering from arthritis in either form. Its
antioxidants help reduce inflammation and improve symptoms of asthma in
addition to arthritis. Squash contains copper, which may be useful for
lessoning the pain of rheumatoid arthritis. Fiber, present in squash, protects
from colon cancer by working to rid the body of harmful substances.
Choose
From Many Excellent Varieties of Squash
Butternut,
turban, hubbard and acorn are all Squashes, along with the familiar pumpkin.
They keep well in a cool dry storage spot, making them an ideal food to store
over the winter months. There are a myriad of ways to prepare Squashes, with
baked, boiled and pies the most common. Squash varieties include pattypan,
yellow squash and zucchini. They are related to cucumbers and melons, and the
seeds are also edible, as is the skin. Zucchini is often prepared in baked
goods, crookneck yellow squash is delicious steamed with butter and pattypan is
great steamed or baked.
