The Health Benefits of Oranges E-mail
oranges
Oranges are classified into sweet and bitter categories, and popular sweet varieties are Valencia, navel, Jaffa and the hybrid blood orange. The bitter oranges are utilized in jams, marmalades, preserves, and liqueurs such as Cointreau.

Oranges are indigenous to China and the south Asian subcontinent, and were first cultivated in the Middle East around the 9th century, and it was Christopher Columbus who introduced orange seeds to North America in the 16th century.

The word orange comes from an old Sanskrit word nagarunga, which means "fruit beloved by elephants". Later on, the word became narandj in Arabic, and then naranja via the Moorish conquests in Spain.

The first recorded use of the word in the form orange is in a Middle English text from somewhere around 1380. Today Brazil is the world’s largest producer of oranges, and in the United States oranges are the biggest fruit crop.

Health Benefits of Oranges

  • Nutrients
    Oranges are an excellent source of flavonoids and vitamin C. They are a very good source of dietary fiber. They are a good source of B vi­tamins (including vitamins Bl, B2, and B6, folic acid, and pan­tothenic acid), carotenes, pectin, potassium, and folic acid.
  • Glycemic Index (GI)
    In a study to determine the GI of various fruits, it was concluded that oranges have a low GI of 42.
  • Cholesterol
    One of the most important flavonoids in or­anges is hesperidin. Hesperidin and the pectin in oranges have been shown to lower cholesterol. The concentration of hes­peridin is considerably higher in the inner peel and inner white pulp of the orange, rather than in its orange flesh.
  • Arthritis
    In a study at the Arthritis Research Campaign Epidemiology Unit in the United Kingdom, results suggested that a modest increase in beta-cryptoxanthin (antioxidant found in oranges) intake, equivalent to one glass of freshly squeezed orange juice per day, is associated with a reduced risk of developing inflammatory disorders such as rheumatoid arthritis.
  • Kidney Stones
    In a preliminary study involving nine healthy and four participants with kidney stones, it was suggested that orange juice consumption might be more effective than other citrus juices in the prevention of kidney stones. Further studies are needed to evaluate these results.
  • Cancer
    The flavonoids naringenin and hesperedin exhibit estrogenic, anticarcinogenic and antioxidative properties. Orange juice contains high amounts of these compounds, and research data suggests that these two flavonoids may be able to inhibit the development of cancer.
    D-limonene is found in the essential oils of oranges and other citrus fruits, and studies have shown that d-limonene to be effective in the prevention of gastric and liver cancer.
    Recent studies indicate that beta-cryptoxanthin may be a promising chemopreventive agent against lung cancer.
