Television infomercials promote machines that turn healthful fruits 
and vegetables into less healthful juices. 

You can't improve on the quality of a food by extracting something 
from it. Protein supplement pills are not more healthful than the 
milk or tuna that was used to make them. An orange is more healthful 
than its juice because it contains more than ten times as much fiber 
that helps to lower cholesterol, reduce weight, prevent constipation 
and gall bladder disease and may even help to prevent colon cancer. 
The average North American gets only 11 out of the required 35 grams 
of fiber per day. 

Juicing won't help you to lose weight. A glass of orange juice 
contains twice as many calories and 1/10th as much fiber as an 
orange. Juice raises blood sugar levels more quickly than the whole 
fruit because the fiber has been removed, leaving primarily sugar 
and water. There is no particular health advantage to turning fruits 
and vegetables into juices, and if you don't get enough fiber in 
your diet, it's a big disadvantage. 

If you must use a juice machine, get the type that is like a strong 
blender and does not remove anything. If your juicer removes pulp 
for you to discard, you are losing valuable nutrients and fiber.

Juices are not Health Foods
