Watermelon is rich in phenolic compounds including flavonoids, carotenoids (lycopene, β-carotene), and triterpenoids (cucurbitacin E). It is a concentrated source of lycopene and cucurbitacin E which are well-documented inhibitors of many inflammatory processes, including the production of pro-inflammatory messaging molecules, the expression of enzymes like cyclo-oxygenase and lipoxygenase that can lead to increased inflammatory response. Both compounds are also well-known antioxidants, with the ability to neutralize free radical molecules. Two more antioxidant compounds found in significant amounts in water melon are β-carotene and vitamin C.
Watermelon is a source of the aminoacid citrulline acid that is commonly converted by our kidneys and other organ systems to arginine. This molecule can be converted to use nitric oxide (NO), which is a muscle relaxant and can cause a drop in blood pressure. Thus, citrulline content is likely to provide us with some cardiovascular benefits.
Watermelon seeds contain small but helpful amounts of both iron and zinc. Interestingly, the iron and zinc in watermelon seeds is surprisingly bioavailable (85-90%), despite the oxalates and phytates that are contained in the seeds.
The fruit is not a concentrated source of fiber, however as it is often consumed in larger amounts it can provide great fiber benefits at a low calorie cost.
