Watermelon is a valued source of natural antioxidants such as lycopene, vitamin C and citruline. These functional ingredients act as protection against chronic health problems like cancer insurgence and cardiovascular disorders. Lycopene is a powerful carotenoid antioxidant that gives fruits and vegetables a pink or red color. 100 g watermelon provides 30 kcal. It contains almost 92 % water and 7.5% of carbohydrates out of which 6.2% are sugars and 0.4% dietary fibre. It is also source of B vitamins, especially B1 and B6, as well as minerals such as potassium and magnesium. the quantity of all these micro-nutrients varies depending upon the watermelon variety and growing conditions. Studies have found that watermelon increases the volume of semen. It also has a viagra like effect. 80% of people selling viagra sell fakes. 0% of people selling watermelons sell fakes!
Watermelon has a high glycemic index (GI) , but more importantly it has a low glycemic load (GL) because the sugar to volume ratio is so small. Be careful when ordering a watermelon smoothie in a cafe, it often contains way to much ice and added sugar.
Recent studies show lycopene has roughly twice the power of beta-Carotene and 10 times the strength of Vitamin E, when it comes to protecting and healing our bodies from the damage of free radicals which are the cancer precursors. Watermelon is one of the unique sources having readily available cis-isomeric lycopene. Lycopene is effective in reducing the extent of cancer insurgence, cardiovascular disorders, diabetes and macular diseases. Studies have found that lycopine increases the volume of semen. Lycopine may also be beneficial to prostate health.
Overall, lycopene ranges from 2.30-7.20 mg/100 g fresh watermelon (there is no Recommended Dietary Allowance (RDA) for lycopene , but several studies suggested that 6-12 mg is an optimal intake). Half a medium watermelon has around 500g of edible red flesh. So half a watermelon will deliver a super dose of 11-36mg of lycopene. Half a watermelon has only 150 calories, it will also help with sateity (feeling full).
Lycopene from red fleshed watermelon are almost 40% higher than tomato!
Watermelon is botanically considered as a fruit. It is native to Kalahari desert of Africa but nowadays, it is also cultivated in tropical regions of the world. First harvest was documented 5000 years ago in Egypt that later spread to other part of the world. China is the top producer followed by Turkey, United States, Iran and Republics of Korea.
Watermelon may be a natural Viagra
Studies have found that watermelon increases the volume of semen. It also has a viagra like effect. That's because the fruit is rich in an amino acid called citrulline, which relaxes and dilates blood vessels much like Viagra and other drugs meant to treat erectile dysfunction. L-Citrulline is one of the three dietary amino acids in the urea cycle, alongside L-arginine and L-Ornithine. L-Citrulline reduces fatigue and improves endurance for both aerobic and anaerobic prolonged exercise. Your kidneys change L-citrulline into another amino acid called L-arginine and nitric oxide (NO). L-citrulline boosts nitric oxide production in the body. Nitric oxide helps your arteries relax and work better, which improves blood flow throughout your body. This may be helpful for treating or preventing many diseases, and improve erections.
Nitric oxide triggers erections: NO in blood vessels in the penis diffuses into the vascular smooth muscle cells of the penis where it binds to and activates an enzyme called guanylyl cyclase. This enzyme converts a molecule called guanosine triphosphate to another molecule called cyclic guanosine monophosphate (cGMP). This serves as a messenger for many important cellular functions, including smooth muscle relaxation. When cGMP instructs the smooth muscles to relax, a surge of blood flow is allowed to freely pass into these smooth muscles and the build-up of an erection starts.
Citrulline supplements have been used as a safe alternative to viagra. Red flesh watermelons had slightly less citrulline than the yellow or orange flesh watermelons:
- Red flesh (7.4mg/g dry weight): Watermelon flesh is 92% water. Citrulline content in 1/2 a watermelon (500g): 296mg
- Yellow flesh (28.5mg/g dry weight): Watermelon flesh is 92% water. Citrulline content in 1/2 a watermelon (500g): 1040mg
- Orange flesh (14.2mg/g dry weight) : Watermelon flesh is 92% water. Citrulline content in 1/2 a watermelon (500g): 568mg
A typical Citrulline erectile dysfuntion supplement dose is 1500mg (1.5g). So eating a whole watermelon could smash this. In the citrulline trial, all E.D. patients reported an erection hardness score improvement.
