Which One Is Healthier, Oranges or Orange Juice?

There is much more to manufacture juice just squeezing some citrus. Fruit juices have been criticized in recent years by a high sugar content, but scientists say that the whole picture is not so clear. They found that although the juices reduce the level of carotenoids, vitamin C and flavornoids present, improved bioavailability (the amount the body can absorb and use). But that's not the whole story.

Research has surprisingly revealed that some of known brands of apple juice contain arsenic .

juice American apple made from apple concentrate, 60% of which is imported from China. Other countries can use pesticides that contain arsenic, a heavy metal known to cause cancer and heart disease.

Results of an investigation Consumer Reports on arsenic and lead in apple juice and grape juice have led the organization to ask for government standards to limit consumer exposure to these toxins.


the weaning populations of fruit juice can be difficult. Research firm market Mintel says 83 percent of us drink fruit juice at least once a week, while 76 percent believe that fruit juice to be healthy.

Ever he wondered why the juice commercial orange - even the premium, not-from-concentrate "100 percent pure" juice type - tastes the same every time you buy it, but do not know exactly like a freshly peeled orange [?

as part of the series production, brands such as Tropicana, Minute Maid, Simply Orange, and Florida native added artificial flavors in order to ensure that the juice has a consistent flavor of the box cardboard -. and to ensure that you know of oranges

"it really rocks world of people to learn more than orange juice is not a fresh product," says Alisa Hamilton , author of " Squeezed: what you Do not want to know about orange juice "

juicy findings

Oranges and its products are rich sources of carotenoids (antioxidants, and a precursor of vitamin a); flavonoids (which is believed to have antioxidant effects) and vitamin C. It also contain lutein and zeaxanthin, compounds that are believed to play an important role in preventing macular degeneration related to age (loss of vision) and cognitive decline in the elderly.

"consumers perceive orange juice as a healthy and natural source of vitamins and other nutrients that promote health, resulting in increased demand and production worldwide" Ralf wrote Schweiggert, one of the authors on the study published in the journal of Agricultural and Food Chemistry. "In addition, convenient packaging and long life juices are advantageous compared with fresh fruit.

" Studies of recent interventions have shown the health benefits of consuming orange juice long term, such as a higher total antioxidant status, total cholesterol and preventing increases endotoxins after meals high in fat and carbohydrates.

"However, increased consumption of orange juice has also been criticized because of its high level of intrinsic sugar, which is associated with an increased risk of type 2 diabetes and cardiovascular disease. "

Should we focus on the juice?

Too natural fruit sugars without fiber to slow digestion and absorption cause a rise in blood glucose. The pancreas secretes insulin to push the glucose into cells, and when the pancreas overcompensates as a result of a spike of glucose, blood sugar will be reduced.

If over time your pancreas secrets too much insulin often, the cells will stop responding, leading to a condition known as resistance insulin . Fruit juices alone do not cause resistance to insulin, but considering that most Americans consume more sugar and refined carbohydrates than they should and not enough fiber, the juices should ensure they consume as much fiber as possible . if the overconsumption of refined processed foods

the study analyzed five different types of products: fresh orange slices orange raw, homogenised segments (mashed), freshly squeezed juice, pasteurized juice and juice flash- pasteurized.

orange juice (fresh and pasteurized) showed 'slightly diminished' levels of carotenoids and vitamin C, for 3-18%. levels of flavonoids and dietary fiber was reduced to about one tenth to dejuicing

However, carotenoids bioavailability. - the ease with which the body can absorb nutrients - was increased from 10.8% in 28.3% oranges in orange juice freshly squeezed. flavonoid bioavailability was driven almost fivefold to 96.5%.

The bioflavonoid hesperidin remained similar in all foods tested.

"The lower levels of flavonoids in orange juice compared to orange segments may be less relevant with respect to intestinal absorption, due to the low solubility of flavonoids in the digestive fluids is considered to be the limiting factor. "

orange juice makes a good example the difference in health when you focus on the question of its flesh. The white part of the orange pulp is the main source of flavonoids. The sections of juicy orange orange contain most of its vitamin C in the body, flavonoids and vitamin C often work together, and support health through their interaction. When the white part of the orange pulp is removed in processing orange juice, the flavonoids in orange are lost in the process.

This loss of flavonoids is one of the many reasons to eat oranges in their whole food form (even if it ends up just eating some of the pulpy white part). Although many commercial products will say "pulp added" on their labels, the "pulp added" many not even be the original pulp found in the whole fruit, and is very unlikely to be added back on the amount withdrawn.

the researchers add that gores maceration of orange not alter bioaccessability carotenoids, suggesting that fiber processing is more significant.

"in contrast to dejuicing, homogenization of orange slices to a puree not improved carotenoid bioaccessability This indicates a minor role of cell disruption and trituration, compared with the removal of the fibers in products orange "
