Why is it good to eat fruit but not fruit juice?

Drinking fruit juice is not necessarily bad. But it is not equivalent to eating fruit , because when you drink the juice of a fruit you are actually taking an undesirable part of several pieces of fruit and discarding other nutritionally interesting parts.

For example, orange juice is made from three oranges, not just one. Juice has two to three times as much sugar but almost none of the fiber, because the pulp is wasted. The problem is accentuated when it is not even natural squeezed juice but comes from orange concentrates, which possibly have added sugar in addition to that contained in the fruit itself, and no pulp. In addition, the juice you drink quickly and without the need to chew while the orange takes several minutes to eat.

That is, drinking a glass of orange juice, in one minute you are taking about 20 grams of sugar, more than 100 calories, 0.5 grams of fiber (2% of the recommended daily amount), it does not fill you up and it is very possible Have a second glass of juice. On the other hand, an orange gives you half the sugar and calories, six times more fiber (about 3 grams, 12% of the recommended daily amount), it fills you up and you do not have the need to eat more.

The fiber in the fruit is important because it regulates intestinal transit, it prevents sugar from being absorbed quickly in the intestines, and therefore, with the same intake of sugars, the body assimilates less.
