Oxidative stress in humans is associated with damage to DNA, proteins, and biological membranes. Oxidative
stress, which often arises as a result of an imbalance in the human antioxidant status, has been implicated in
aging and a number of human diseases such as cancer, atherosclerosis, and rheumatoid arthritis.

Watermelon benefits - antioxidants
Watermelon contains high concentrations of lycopene, an antioxidant that may help reduce the risks of the
diseases relatd to oxidative stress. [1]Within 30 minutes after consumption, orange, melon, grape, peach,
plum, apple, and kiwi juices already effectively suppressed reactive oxygen species generation. This radical
scavenging effect of fruit juices was maintained for up to 90 minutes post-consumption. These results
suggest that the consumption of fruits or fruit juices may reduce damage from oxidative stress, and that this
effect may be a consequence of the antioxidant activity of fruits in scavenging the reactive oxygen species
generated in human plasma. [2] A study has shown that lycopene was bioavailable from both fresh-frozen
watermelon juice and canned tomato juice.

Watermelon benefits - on erection dysfunction
Betsy Blaney, a writer from Associated Press, wrote "A slice of cool, fresh watermelon is a juicy way to top off
a Fourth of July cookout and one that researchers say has effects similar to Viagra!" in her news report. [1]

Watermelons contain an ingredient called citrulline that can trigger production of a compound that helps
relax the body's blood vessels. Citrulline reacts with the body's enzymes and is changed into arginine.
Arginine boosts nitric oxide, which relaxes blood vessels, the same basic effect that Viagra has, to treat
erectile dysfunction. [1]

The nitric oxide can also help with angina, high blood pressure and other cardiovascular problems. Thus,
eating watermelon benefits the heart and the circulatory and immune systems. [1]

Watermelon benefits - on sperm counts
Study also have suggested that taking an arginine supplement for weeks or months would significantly
increase the production of sperm and drastically improve erection.   The effective doses range from 2 to 5
grams per day. [2]

Bhimu Patil, a researcher and director of Texas A&M said that watermelon rind contains 60% more ciltrulline
than in the flesh. And, among different watermelons, the yellow-fleshed types contain the most citrulline.

However, you need to have about six cups of watermelon to get enough citrulline to boost the body's
arginine level. In addition, watermelon is a diuretic, you may need to "visit bathroom" frequently after taking a
large quantity of watermelon. Another issue is its amount of sugar, this may lead to side effect of cramping.

Though its high content of sugar, some researchers believe that intake of watermelon may benefit those who
are obese or suffer from type-2
diabetes. [1]
Watermelon is fat free, nutritionally low in calories and considered an ideal diet food, and is high in energy,
making it a great energy boost!

Watermelon, the fruit that is really a Vegetable. Watermelon can be traced back to Africa and is part of the
cucumber and squash family. Early watermelons were mainly rind and seeds. Today's varieties are larger,
the flesh sweeter, the seeds smaller and the rind thinner. It is perhaps the most refreshing, thirst quenching
fruit of all. Watermelon consists of 92% water and 8% sugar, so it is aptly named. Americans eat over 17 lbs
of watermelon each year. The largest one on world record (Guinness Book of World Records) weighed 262

When to look for them in your grocery store:

Watermelons are available all year. The natural sweetness of watermelon makes it a favorite anytime of the
year. It is a perfect addition to a salad, salsa, or cool drink. Top chunks of sweet watermelon with fruit
flavored sherbets or sorbets.

Nutritionists have long appreciated the health benefits watermelon provides. Recently research has shed new light on its
potential health benefits.
Choose firm, symmetrical, fruit free of cracks, bruises, soft spots or mold. Ripe watermelon will have a healthy
sheen, a dull rind, dried stem, and a buttery yellow underside where it touched the ground. There should be a
melon like smell or fragrance. Thump if you must, sound should be dull and hollow. Lift them, weight should be
heavy for size.

Special Tip
Avoid watermelons that are very hard, white or very pale green in color on the underside, indicating immaturity.
An immature watermelon will be slightly acidic.

Once picked, watermelon will not ripen easily.  If unripe, try putting the whole melon in paper bag
un-refrigerated. This sometimes works to ripen them.  Watermelons can be kept for short periods of time, up to
2 weeks, uncut at room temperature.  Wash watermelon with soap and water before cutting.  Once cut,
package what is not eaten in closed plastic containers or bags and put back in the refrigerator.

There are more than 50 varieties of watermelon. Most have red flesh, but there are orange and yellow-fleshed
varieties. Of the 50 varieties of watermelon throughout the United States, there are four general categories:
