The Benefits of Orange Juice

Orange juice remains the most commonly consumed fruit juice in America. Though it is on many breakfast tables, the benefits of orange juice remain poorly understood, says a study published by the U.S. Department of Agriculture's Economic Research Service. It is, however, a healthy drink for several reasons.

Provides Vitamin C

Drinking at least two glasses of orange juice per day increases the vitamin C concentration within the body by 40 to 64 percent, according to the said study published in the September 2003 "The American Journal of Clinical Nutrition." Vitamin C, an essential vitamin that cannot be synthesized by the human body, is an important antioxidant, a substance that protects the body against the harmful effects of free radicals, the molecules that may cause tissue damage and early aging.

Improves Diastolic Blood Pressure

Regular orange juice consumption may improve diastolic blood pressure, suggests a study published by "The American Journal of Clinical Nutrition" in January 2011. According to this study, orange juice contains hesperidin, a healthy water-soluble plant pigment. Hesperidin serves to improve the activity of small blood vessels, blood pressure and decrease the cardiovascular risk biomarkers in susceptible patients.

Decreases Bad Cholesterol Levels

Regular orange juice consumption may lead to the decrease the level of low-density lipoprotein cholesterol in patients with high cholesterol level, suggests a study published in the October 2010 issue of the "Nutrition Research." However, the mechanism behind this blood cholesterol level improvement with orange juice consumption is still unclear. Further studies and clinical trials are necessary to further establish this fact.
