Is squeezed juice as nutritious as eating fruit directly?

Of course not. If we talk about nutrition alone, of course eating fruits directly is more nutritious than drinking juice. There are three reasons:

1. Cellulose and pectin are destroyed

Although juice is also made by pressing and filtering fruit, during the pressing process, the soluble components in the fruit are destroyed. All the sugars, including the sugars, are passed into the juice, while the insoluble substances, including all the cellulose and most of the pectin, are given up.

These are precisely one of the most important nutrients in fruits. They have certain effects on maintaining intestinal function, promoting intestinal peristalsis, preventing constipation, interfering with glucose absorption, lowering cholesterol, and fighting cancer. effect. In addition to dietary fibers such as cellulose and pectin, other nutrients in the fruit such as calcium, iron and other insoluble elements will also be filtered out with the residue. So many important nutrients are filtered out during the pressing process, and the nutritional value of the juice Of course it's a big discount.

2. Vitamin C is oxidized

For squeezed juice, since the pulp is completely crushed and destroyed during the squeezing process, the cell structure of the fruit will be destroyed, and the pulp will be fully mixed with oxygen. The polyphenols and very delicate vitamin C in it will be oxidized within minutes when exposed to it, and the juice will turn into an unsightly dark brown color. But it is not just a difference in appearance, but more importantly, these many The antioxidant capacity of phenolic nutrients and vitamin C will also be weakened as a result, and of course it is not as healthy as whole fresh fruits.

3. Intake more sugar

Even if it is homemade juice, for a better taste, a considerable amount of sugar must be added to be acceptable. Generally, the sugar content of commercially available apple juice and orange juice is more than 8%, and the sugar content of grape juice can even be as high as 15%-20%. Moreover, it is easy to drink too much of the sweet and sour juice. Drink a bottle of 425 ml. Apple juice is quite relaxing, but you inadvertently eat 40 grams of sugar. Eating two fresh apples only contains more than 20 grams of sugar. Of course, eating fresh fruit is healthy and safe.

Of course, if you are an elderly person with bad teeth or an infant who has no chewing function, or a patient with eating difficulties, it is recommended that you drink homemade freshly squeezed juice, although it has certain nutrients. Loss, but eating is better than not eating at all. After all, nutritious fruits are indispensable to all of us.
