Orange juice is a popular beverage made from the extraction (squeezing) of liquid from fresh oranges. The term "orange juice" is also used, both colloquially and commercially, to refer to "concentrated orange juice".Orange juice is a source of vitamin C (ascorbic acid), potassium, thiamine, Phosphorus G, folic acid (Vitamin B9) and vitamin B6. Research shows orange juice is more nutrient dense than many commonly consumed 100 percent fruit juices, such as apple, grape, pineapple and prune.
Citrus juices also contain flavonoids that are believed to have beneficial health effects. Orange juice containing pulp seems to be more nutritious than no-pulp varieties due to the flavonoids contained in the pulp.If drunk on an empty stomach, orange juice can exacerbate present gastrointestinal conditions and/or cause mild and temporary stomach upset. Due to the citric acid, orange juice typically has a pH of 3.5.Drinking or sipping orange juice can therefore cause erosion of the tooth enamel, otherwise known as 'acid erosion'. Some publications recommend using a straw when drinking orange juice so that the juice does not come into contact with the teeth.
Apple juice is a common beverage for both children and adults. Apple juice is also a component of several cocktails, and is a filler in some other fruit drinks, because it is less expensive and more widely available than other juices. It may also be produced and consumed in a carbonated form, referred to as sparkling apple juice.Vitamin C is sometimes added by fortification, because content is variable, and much of that is lost in processing. Other vitamin concentrations are low, but apple juice does contain various mineral nutrients, including boron, which may promote healthy bones. Apple juice has a significant concentration of polyphenols that may protect from diseases associated with ageing due to the antioxidant effects which help reduce the likeliness of developing cancer. Research from the University of Massachusetts Lowell (UML) suggests that apple juice increases acetylcholine in the brain, resulting in increased memory.[
Pomegranate juice is juice made from the pomegranate fruit. It is used in cooking both as a fresh juice and as a concentrated syrup.While preliminary research has shown that the fruit juice may play a role in reducing the risk of cancer, reducing serum cholesterol, and protecting arteries from clogging, more research is needed to validate these findings. Its possible benefits also need to be balanced against its high caloric content derived from its natural sugars.
The cholesterol reduction effect has been observed only in small studies.This, as well as the anti-clogging effect of pomegranate juice, are the result of its concentration of antioxidants, and are similar to the effects shown in studies of red wine, black tea, and purple grape juice. There have been no large clinical trials showing that antioxidants can prevent heart attacks or other major heart-related events.
People who had undergone surgery or radiation therapy for prostate cancer could significantly slow the increase of prostate specific antigen when they consumed a glass of pomegranate juice daily.
A 250 ml (8 oz) glass of pomegranate juice provides approximately 50% of an adult's recommended daily allowance (RDA) of the vitamins A, C and E, 100% RDA of folic acid, and 13% RDA of potassium.
Notwithstanding the possible benefits of the juice, each such glass also tops the maximum daily amount of sugar, as recommended by The Food and Agriculture Organization and World Health Organization. The organizations jointly recommend that only 10% of calories come directly from sugars . With almost 30 grams of sugar, a glass of pomegranate juice has more sugar than an equal size serving of some soft beverages, such as Coca Cola Classic and roughly equal to two servings of a sweetened breakfast cereal
