Cucumber is a creeping vine with a cylindrical shape when ripe. It is originally from Indian subcontinent but the crop is widely well cultivated in most continents including Africa. It is considered as a simple vegetable with enormous health benefits because of its low calories and fats. It has vitamins, minerals, protein and dietary fibre which are very good for people who want to stay health and fit.
Here are the health benefits of cucumber:
1)
Hydration
According to Ware, “Cucumbers are 95 percent water." This makes
cucumbers a great way to stay hydrated, especially during the summer. A
cup of cucumber slices is “nearly as thirst-quenching as a glass of
water,” according to
Eating Well magazine.
The anti-inflammatory compounds in cucumbers help
remove waste from the body and reduce skin irritation, according to the Cleveland Clinic. Preliminary research also suggests cucumbers
promote anti-wrinkling and anti-aging activity, according to an article in the journal Filoterapia.
2)
Cancer prevention
Cucumbers contain two phytonutrient compounds associated with
anti-cancer benefits: lignans and cucurbitacins. In recent years,
pharmaceutical companies have been paying special attention to
cucurbitacins, hoping to use them in new cancer drugs. According to a
2010 research review published in
Scientific World Journal,
scientists have found that cucurbitacins can help block the signaling
pathways that are important for cancer cell proliferation and survival.
Cucurbitacins can also inhibits the growth of pancreatic cancer cells, according to a 2009 study published in the
Journal of Cancer Research looked
at cucurbitacin B (which cucumber contains) on human pancreatic cancer
cells and found that cucurbitacin supplements inhibited the growth of
seven pancreatic cancer cell lines by 50 percent, and also increased
apoptosis, or "death by suicide," of pancreatic cancer cells.
According to World’s Healthiest Foods, lignans may protect against
cancer through working with the bacteria in the digestive tract. The
bacteria take the lignans and convert them into compounds such as
enterodiol and enterolactone, which can bind onto estrogen receptors and
possibly reduce the risk of estrogen-related cancers, such as ovarian,
breast, endometrial and prostate cancers. The research is not yet clear
on whether lignans actually assert anti-cancer benefits.
A 2009 meta-analysis published in the
British Journal of Cancer found
little or no association between lignan intake and reduced breast
cancer risk. Similarly, most studies have not found significant
correlations between lignan intake and reduced prostate cancer risk,
according to the
Linus Pauling Institute at Oregon State University, though one study of older Scottish men published in the
British Journal of Nutrition showed that consuming an enterolactone-containing serum reduced the risk of prostate cancer.
On the other hand, a
Journal of Nutrition study
of nearly 800 American women found that those with those with the
highest lignan intake had the lowest risk of ovarian cancer.
Furthermore, a study published in the
Journal of the National Cancer Institute looked
at nearly 1,000 women in the San Francisco area and found that
postmenopausal women with the highest lignan intakes had the lowest risk
of endometrial cancer.
3) Skin
You’ve probably seen pictures of people at a spa relaxing with cucumber
slices over their eyes. It turns out there’s science behind this
pampering ritual. Ware explained, “Cucumbers have a cooling and soothing
effect that decreases swelling, irritation and inflammation when used
topically. Cucumber slices can be placed on the eyes can decrease
morning puffiness or alleviate and treat sunburn when placed on the
affected areas.” She also noted that high vegetable intake is associated
with a healthy complexion in general.
4) Bone health
According to the
University of Maryland Medical Center,
in the past few decades, it has become clear that vitamin K is
important to bone health, and one cup of cucumber contains about 19
percent of the recommended daily intake of vitamin K. One review
published in
Nutrition noted
that vitamin K intake might reduce fracture rates, work with vitamin D
to increase bone density and positively affect calcium balance.
The human body uses vitamin K when building bones, and the effects seem to be especially important for women. A large 2003
American Journal of Clinical Nutrition study
showed that low vitamin K levels were associated with low bone density
in women, but not in men. Another study published in the
American Journal of Clinical Nutrition in
1999 found that low intakes of vitamin K were associated with an
increased risk of hip fractures in middle-age women. This is especially
interesting because the women saw results from eating lettuce, showing
that dietary consumption of vitamin K via eating vegetables (not
supplements) is beneficial. When it comes to men, the affects of vitamin
K and bone health may become more apparent as they age: A 2000
study saw reduced risk of hip fracture among both elderly women and elderly men who consumed more vitamin K.
5) Antioxidants
Cucumbers contain several antioxidants, including vitamin C,
beta-carotene and manganese, as well as flavonoids, triterpenes and
lignans that have anti-inflammatory properties. Vitamin C is well known
for its immune system benefits, and beta-carotene has been shown to be
beneficial for vision, according to the
Mayo Clinic.
According to a 2010 animal study published in the
Journal of Young Pharmacists,
fresh extracts from cucumber showed increased scavenging of free
radicals. Free radicals are associated with a variety of human diseases,
but can sometimes be held in check by antioxidants, according to the
Pharmacognosy Review.
Another study of cucumber extracts in animals, published in the
Archives of Dermatological Research,
found increased overall antioxidant benefits. Though this study focused
on the cosmetic applications of this use of cucumbers, decreased free
radicals can improve your inside organs as well as your skin.
An additional study published in
Current Pharmaceutical Design found
a positive association between the triterpene cucurbitacin and reduced
inflammation, particularly in cancer cells. A review of triterpenes on
the immune system, published in the
Journal of Ethnopharmacology, suggested that they can help with inflammation and encouraged future research.
6) Heart health
“Eating a variety of fruits and vegetables of all kinds is associated
with a reduced risk for many health conditions, such as heart disease,
diabetes, stroke and obesity,” said Ware. Cucumbers’ potassium content
may be especially helpful in this regard. One cup of sliced cukes
contains only about 4 percent of the body’s daily potassium needs, but
it comes with significantly fewer calories than most high-potassium
foods like bananas. Potassium is an essential part of heart health,
according to the
American Heart Association.
Many studies have linked it with lower blood pressure because it
promotes vasodiliation (widening of the blood vessels), according to
Today’s Dietitian. A study of 12,000 adults, published in
Archives of Internal Medicine,
showed that those who consumed 4,069 mg of potassium each day lowered
their risk of cardiovascular disease and ischemic heart disease by 37
percent and 49 percent, respectively, compared to those who took 1,793
mg per day.
The vitamin K in cucumbers is also known to be essential in the blood-clotting process, according to the
Harvard School of Public Health.
