Although fruit juice is rich in nutrition, it is not a drink that can be drunk to the fullest. First of all, if there is satisfactory sweetness in fruit juice, the sugar content will reach about 10%, and some even higher. If you drink 2 cups of juice in addition to three meals, it will increase the calorie of 160 kcal, which is equivalent to half a bowl of rice.
For people who want to lose weight, it is unwise to drink a lot of fruit juice. Tea without energy is the best choice. Secondly, there is almost no protein in the juice. Although most fruit juices contain a certain amount of vitamin C, the content of B vitamins is very low.
Therefore, although the juice looks good, don't drink too much. Drink 1-2 cups every day, preferably between meals or before meals. People with diabetes can eat low-sugar fruits such as strawberries, but it is best not to drink fruit juice. Dieters and hyperlipidemia patients should also drink less juice. When you feel thirsty, the preferred drinks are boiled water and green tea. Choose black tea in autumn and winter, and green tea is better in summer. They don't contain any energy. Black tea has a remarkable lipid-lowering effect, while green tea is rich in anticancer substances.
Extended information: introduction of freshly squeezed juice:
1. Fresh juice is juice squeezed from fresh fruit. Drinking some juice can properly supplement some nutrition. If adults can't ensure a reasonable diet, and people who don't like boiled water, sweet juice can increase their drinking water, especially in summer.
In addition, fresh fruit itself contains a lot of dietary fiber necessary for human body. After squeezing into juice, dietary fiber will remain in the pomace. Therefore, in order to supplement the dietary fiber needed by the human body, it is recommended to eat the pomace as well.
More and more people use freshly squeezed fruit and vegetable juice instead of fresh fruits and vegetables, which is really good in nutrition. After entering the human digestive system, it will make the blood alkaline and expel toxins accumulated in cells, such as heavy metals such as lead, aluminum and mercury and free radicals, so it has the function of detoxification and purification.
4. It has the functions of promoting digestion, stimulating appetite, whitening skin, and keeping fit and losing weight. For patients, the elderly and infants, gastrointestinal function is weak, gastrointestinal peristalsis is slow, there are fewer lactic acid bacteria in the intestine, and food remains in the gastrointestinal tract, which is difficult to digest. It is very suitable for supplementing the deficiency of nutrients in the diet by drinking fruit juice. If adults cannot guarantee a reasonable diet.
In fact, when drinking freshly squeezed juice, it is recommended to eat even the fruit residue. Freshly squeezed fruit juice contains nutrients such as sugar, fat and trace elements obtained by the human body, which is similar to eating fresh fruit. But the biggest deficiency is that fruits lose a lot of dietary fiber necessary for human body during fresh pressing. The water-soluble fiber represented by pectin has the health care function of preventing and reducing diabetes and cardiovascular diseases.
6. Insoluble fiber is more used to prevent gastrointestinal diseases, which can stimulate intestinal peristalsis and promote defecation. In addition, dietary fiber can also affect the blood sugar level, reduce the dependence of diabetic patients on drugs, prevent excess calories, control obesity, prevent gallstones and reduce blood lipids. The best way to solve the problem of less dietary fiber in fruit juice is to eat the solid residue left after juicing, so that the nutrients will not be lost.
7. In addition, don't heat the fruit after juicing, which will cause different degrees of damage to vitamins. It is not advisable to drink high-concentration juice on an empty stomach to avoid hurting the stomach. Don't drink too much for lunch and dinner, because a lot of fruit juice will dilute the concentration of gastric juice, and the fruit acid in fruit juice will also combine with some nutrients in the diet, which will affect the digestion and absorption of these nutrients.
8. Prostate fluid contains many trace elements besides protein and various enzymes, among which zinc is the majority. It is reported that the zinc content in prostate tissue is much higher than that in other tissues.
9. An experimental study abroad found that prostatic fluid contains a certain amount of antibacterial components. Further research proves that this antibacterial substance is a kind of protein containing zinc, and its main component is zinc, and its antibacterial effect is similar to that of penicillin, so it is called the antibacterial component of prostatic fluid. It is also found that the zinc content in chronic prostatitis is obviously decreased and it is difficult to increase.
10. A foreign clinical medical study found that apple juice has amazing curative effect on zinc deficiency. This study is called "Apple Therapy". Compared with the commonly used zinc-containing drug therapy, apple juice is more effective than drugs with high zinc content, and it is safe, easy to digest and absorb, and easy to be accepted by patients. In addition, the curative effect of "apple therapy" is directly proportional to the concentration of apple juice, and the greater the treatment, the better the curative effect. Therefore, it is very beneficial for patients with chronic prostatitis to eat apples often.
