Squeezed fruit is as healthy as eating a piece of raw fruit out of your hand. Unlike many people think there is not a whole lot of fruit flesh lost when you squeeze fruit. This means that your glass of orange juice does contain all the fibers you need! These fibers prevent from many diseases. Fibers stimulate the digestive system so if you have a substantial amount of fruit intake it is not necessary to eat bran or other intestine stimulating foods.
If you are in the possession of a fruit press you can squeeze the citrus fruits. Real fruit lovers also have a blender so they can make mixes of all types of fruit. A juice-centrifuge easily extracts the juice out of all fruits and many vegetables and is in our opinion for the more extreme squeezers who also want to drink vegetable juices. It is not very practical in use (a lot of cleaning) and for squeezing almost any type of fruit a fruit press and a blender will do.
Try to get it into your system: squeeze those wonder-fruits yourself everyday. Freshly squeezed juices are best. Magical characteristics are ascribed to freshly squeezed juice. Avoid to drink fruit juice from a can or glass bottle because when the bottle or can is closed the juice is heated and gets an acid structure. Juice from cartons, cans and glass bottles has been pasteurized. This means the juice has been heated (cooked) to kill all the germs. The heating of food changes the enzymes of the food so it looses (some of) its nutritious value. This means you can't substitute freshly squeezed juice by juice from cartons.
