Like no other fruit, watermelon is considered by many to be a perfect  
Summer fruit. Thanks to its high water and mineral content, water melon 
 is a tasty thirst quencher. This quality was greatly appreciated as far
  back in history as Ancient Egypt and Ancient China.  
Watermelon (Citrullus lanatus) belongs to the family Cucurbitaceae. It  is a 
vine-like flowering plant that most probably originated in Southern  
Africa. The plant produces large fruits whose flesh is pink or dark red 
 when ripe. The fruits are covered with thick, green rind. There are  
more than 1200 varieties cultivated all over the world.
Watermelon is rich in nutrients:
- vitamins,
 especially the vision supporting vitamin A, the immune  system 
modulating vitamin B6 and the immune system boosting vitamin C 
- minerals, especially magnesium and potassium
- amino acid citruline 
- carotenoids lycopene and beta carotene
- flavonoids lutein, zeaxanthin and cryptoxanthin
- tripterpenoids
As mentioned before, because of its very high water content, watermelon 
 is a  wonderful thirst quencher. In Traditional Chinese Medicine the  
red flesh of the fruit is considered to be cooling and used to purify  
blood and dispel symptoms of internal and external heat. A very popular 
 watermelon lozenges are prescribed to cure sore throat. To address  
different symptoms, Chinese doctors use all parts of the fruit,  
including the rind and the seeds. 
Watermelon is a perfect anti-aging superfood. It has few calories, but  
is very rich in phenolic compounds that include flavonoids, carotenoids,
  and tripterpenoids. These compounds help fight inflammation and 
provide  protection against free radicals.
The carotenoid lycopene that gives watermelon its red color, is a very  
effective free-radicals scavenger. In fact, watermelon contains higher  
levels of lycopene than any other fresh fruit or vegetable - 15 to 20 mg
  per two-cup serving. The content depends on the ripeness of the fruit.
Lycopene has the ability to inhibit many inflammatory processes in the body including: 
- the production of pro-inflammatory messaging molecules 
- the expression of such enzymes as the cyclo-oxygenase and the lipoxygenase that can lead to increased inflammatory response
- the activity of molecular signaling agents like nuclear factor kappa B (NFkB)
Another
 anti-inflammatory compound, the tripterpenoid cucurbitacin E,   blocks 
the activity of cyclo-oxygenase enzymes and neutralizes reactive  
nitrogen-containing molecules or the RNS.
 
Watermelon
 is an amazing source of the amino acid citrulline. The flesh  of a 
watermelon contains about 250 mg of citrulline per cup. Among  others, 
citrulline is converted by the kidneys  and the endothelial cells (cells
 that line our blood vessels), into  amino acid arginine. An enzyme 
called nitric oxide synthase or NOS,  takes the amino acid arginine and 
uses it to help  produce nitric oxide (NO). NO is a  muscle relaxant 
that tells the smooth muscles around our blood vessels  to relax. When 
this happens, the space  inside our blood vessels can expand, allowing 
blood to flow more freely.  The relaxation of muscle tension  and 
increase in blood flow constitutes the mechanism by which NO can  
improve the erectile  function in men. Although consumption of 
watermelon significantly  increases levels of arginine in the body, the 
amount of citruline is not  enough to cure erectile dysfunction with one
 portion of watermelon  alone. 
Citruline
 also has the ability to flushe the kidneys and  the liver of stored 
aluminum. Aluminum can be damaging to the cells. It not only  enters our
 bodies from the environment, but is also a byproduct of protein 
breakdown within the body.
Latest
 research also demonstrated that citruline may affect the way fat  is 
deposited in the human body. When citruline converts into arginine,  
arginine-related molecules called polyarginine peptides are also formed 
 in the body. These compounds are able to block activity of an enzyme  
called tissue-nonspecific alkaline phosphatase, or TNAP. When TNAP  
activity is shut down, fat cells (adipocytes) create less  fat. The less
 fat is produced, the less fat is deposited in the body.
Watermelon seeds are also beneficial to health. They contain B Vitamins;
  incredibly bio-available iron and zinc; magnesium; omega 6 fatty 
acids;  and  the cardiovascular system supporting amino acid arginine. 
They also  contain lysine, tryptophan, and glutamic acid. 
The nutrient content makes watermelon one of the healthiest foods  
available to us. Although a ripe watermelon contains sugar, the fruit  
has a law glycemic index which means that it will not cause rapid spikes
  in blood glucose levels. Some animal studies suggest that watermelon  
juice may even have a positive effect on blood sugar metabolism.  
 
Watermelon is considered to be a natural diuretic. It helps increase the
 urine  flow, but unlike caffeine it does not put any strain on the 
kidneys.  Moreover, watermelon helps the liver process ammonia.
Watermelon is a good source of amino acids cystein, glutamate and  
glycine that are necessary for the synthesis of glutathione. Glutathione
  is the body own antioxidant, detox agent and immune system modulator. 
 Glutathione helps the body effectively excrete mercury, aluminum and  
pesticides, and improves the efficacy of vitamins C and E in the body.
When fully ripe, watermelon is an alkaline-forming fruit. This fact  
alone makes watermelon incredibly beneficial to health as diseases such 
 as cancer can only thrive in an acidic environment.
