Agricultural Research Service scientists in northern California led by chemist Gary D. Manners of the Western Regional Research Center in Albany have uncovered new details about these compounds. Their research has demonstrated that our bodies can readily access a limonoid called limonin, and all of its health-imparting properties, each time we bite into an orange. This is the first time that bioavailability has been shown in humans.
In some individuals, limonin remains in the bloodstream for up to 24 hours which is an impressive length of time. This longevity, or persistence, may help explain why limonoids fight the type of cancer cells which proliferate unless they are continuously suppressed.
A single orange provides 12.5% of the daily value for fiber, which has been shown to reduce high cholesterol levels and to prevent atherosclerosis. A single orange offers you over 170 different phytochemicals and more than 60 flavonoids, many of which have been shown to have anti-inflammatory, anti-tumor and blood clot inhibiting properties, as well as strong antioxidant effects.
Although oranges are the major fruit in the citrus fruits group don’t forget about the others such as Tangerines, Mandarines, Clementines, Satsumas, Lemons, Limes and Grapefruits.
