100% of fruit juice in the market is not necessarily squeezed from fresh fruit. It can be said that the freshly squeezed juice bought in the market is not necessarily healthier than ordinary juice.
Freshly squeezed juice and reconstituted milk juice sold in the market are claimed to be 100% juice on the packaging, but in fact, many juices are reconstituted milk juice made of water and concentrated juice.
The freshness of freshly squeezed juice often makes people feel healthy. But this is not the case. Fresh pressing seems to be a physical treatment of fruit, which should be to turn eating fruit into drinking fruit. But it can't be judged that the freshly squeezed juice sold in the market is definitely healthier than the reduced juice.
From the point of view of nutrition and health, the nutritional components of fruit juice mainly come from fresh fruits. Therefore, the quality of fresh fruit directly determines the nutrition of juice. Generally speaking, the fruit used for fresh juice is unlikely to be better than the fresh fruit directly sold in the market.
Studies have shown that freshly squeezed juice can increase postprandial glycemic index compared with whole fruit. One is eating and the other is drinking. If you eat fruit directly, the process of chewing will slowly release and absorb sugar, and it will take about two hours from eating to absorbing nutrition, so it will not strongly stimulate the glycemic index. Fresh fruit is eaten directly, because it contains cellulose, and the nutrient absorption rate is only 17%. However, the absorption rate of nutrients in freshly squeezed juice can reach 65% because of the removal of cellulose, and the absorption time of nutrients is shortened to a quarter of an hour, which is more stimulating to the blood sugar index.
