Does lemon really have whitening effect?

Because lemonade tastes good, it has many other functions. ? Lemon peel contains dietary fiber (DF), which has the advantage of high content of water-soluble dietary fiber and is rich in flavonoids and VC. Water-insoluble dietary fiber is mainly used to make intestinal peristalsis and prevent constipation, while water-soluble dietary fiber (SDF) plays more metabolic functions, such as preventing gallstones, eliminating harmful metal ions, lowering serum and liver cholesterol, and inhibiting postprandial blood sugar increase, which is related to the physical and chemical characteristics of IDF and SDF. At the same time, lemon DF has the ability to prevent chronic diseases. The content of SDF in lemon DF is also very high, which makes it of great significance in balancing people's DF sources. In the latest edition of Reference Intake of Dietary Nutrients for China Residents (20 13), China Nutrition Society stipulated that the specific recommended level (SPL) of DF was 25 g, and required that SDF should account for 30% ~ 50% of IDF, and the composition of SDF content of lemon DF could just meet this requirement. ?

Drinking lemonade on an empty stomach in the morning is recommended to be light, otherwise the acid will stimulate the stomach, and drinking lemonade on an empty stomach is not recommended if there is stomach trouble. ? Lemonade also helps to change the pH value of urethra and prevent the growth of harmful bacteria.
