The pros and cons of fruit juicing

of high-priced freshly squeezed juices has been in vogue these days, and high-end machines for making juices have been buzzing. However, "high price" products do not mean perfect function, "fashion" eating does not necessarily mean that it is really healthier.before discussing the pros and cons of fruit juice, do you know anything good about fruit?fruit is an important enjoyment of the diet, but also for the human body to provide health-beneficial many nutrients and antioxidant active substances. The main nutrients in fruits are vitamin C and potassium, and also provide phosphorus, cellulose, carotene, organic acids, flavonoids, antholine, phenolic acid and other healthy substances. Among them, soluble dietary fiber such as phosphorus has the effect of lowering blood sugar, lipids and blood cholesterol, while insoluble fiber can promote intestinal peristalsis and help prevent bowel cancer. So what happens to the health effects of fruit juice?The defects of fruit juice1, in the complete fruit cells, there are complex microstructing, like a unit, there will be many rooms, each room, put things are not the same, can not be mixed together. For example, nutrients such as vitamin C run out of cells after juicing and are exposed to oxygen and oxidase, which can cause damage even if not heated. Especially when syringe at high speed with a blade, vitamin C is more lost than cooking directly in a pot. In contrast, citrus juice and other acidic juice vitamin C preservation rate is relatively high, while watermelon juice, pear juice, peach juice, etc. are more loss. Of course, in addition to vitamin C, antioxidants such as flavonoids and phenolic acid can also cause varying degrees of loss due to exposure to oxygen.2, if not hotly boiled, fruit juice should be immediately after drinking, and not like fruit can be "tun" for a few days. It can be said that the loss of vitamins and antioxidants increases every minute. If the enzyme has been inactivate after hot cooking and juice, it should be 2000 to keep it in the fridge for a day. Of course, oxidizing color-changing fruit juice, not can not drink, but its antioxidant capacity, taste is poor.3, in the process of juice, the fruit's soluble dietary fiber has a small part into the juice, insoluble fiber is lost in the slag. Some of the fruit calcium, magnesium and other minerals because of the combination with dietary fiber, but also left in the slag. If the pulp is eaten with the slag, there is little loss of fiber, but if all the slag is removed, as in the juicer, most of the fiber will be lost. Fiber loss not only reduces the disease prevention value of fruit, but also reduces the satiety of fruit. This disadvantage, actually by some juicers with "remove the slag, let heavy metals and dietary fiber combined to help detox" and other words for beautiful packaging, and many believers, can be lamented.4 and the fruit is juiced, almost all the sugar in the fruit is squeezed out. In other words, the power of fruit to gain weight is preserved in fruit juice. It's not easy to eat six apples in a row, but the juice from six apples is easy to drink in 10 minutes. Studies abroad have shown that even pure fruit juices of more than 1 cup (200 grams) a day increase the risk of obesity and diabetes, while eating whole fruits directly does not increase the risk of diabetes, despite their sweet taste.the benefits of fruit juice 1, fruit juice, can help some people who have difficulty eating fresh fruit, such as the elderly with bad teeth, such as patients with extremely weak gastrointestinal function. For this part of the people, although drinking fruit juice is better than eating fruit directly, but also better than not eating fruit at all.2, if the fruit at home taste bad, tasteless food, abandoned a pity, may as well be juiced, not only to avoid waste, but also to promote the intake of fruit.3. For those who really refuse to eat vegetables, or do not have the conditions to eat vegetables, combining fruits and vegetables to juice can increase the intake of vegetables, increase the intake of potassium, magnesium, vitamin C and antioxidants in the diet, because sweet fruit juice will be better than pure vegetable juice.4, increase the purchase of fruit, good for fruit farmers, juicer enterprises are also good, can stimulate economic growth at home and abroad.in short, it's fair to say that freshly squeezed juices are better than juice drinks that contain only 10% juice, but the health benefits are not as good as complete fresh fruit. Even freshly squeezed juice, if drunk outside of three meals, too much can still pose a risk of obesity. If you use it instead of three meals a day, two days a month can also, long-term fruit juice substitute meals, may cause malnutrition.for obese people and diabetics, eating more vegetables is necessary, fruit can also be ingested in moderators, but it is best not to drink fruit juice. Patients with hyperlipidemia and gneumure should also limit their consumption of fruit juice, as sugar from fruit is also sugar, too much sugar will promote the synthesis of triglycerides, and promote endouric uric acid production.in short, if the teeth and gastrointestinal function are normal, can eat complete fruits and vegetables, then still work their own teeth to juice it! We'll have plenty of opportunities to enjoy liquid food when we get old and our teeth fall out in the future.
