Fruit juice is easily absorbed by the stomach, which can save a relatively long digestion process and supplement nutrition more effectively. Usually, the general food we eat stays in the stomach for about two hours and stays in the small intestine for three hours before it can be absorbed by the blood. After drinking fruit juice for 20 minutes, it will be absorbed by the blood and then transmitted to various organs of the body. This is because when fruits or vegetables are squeezed into juice, the enzymes in them are released and absorbed by the human body to play a role quickly. This helps the body to decompose and inhibit harmful substances frequently, and also speeds up the transport of nutrients in fruit juice. If you eat a meal made of fruit and vegetable juice for four or five days in a row, the symptoms of some chronic diseases can often be greatly improved or even disappeared. Fruit and vegetable juice diet can also help people know more about their diet choices. Fruit juice is convenient to eat and can be properly drunk anytime and anywhere. Generally, it is best to drink before and after meals, and it is better to drink on an empty stomach between meals in the morning. Drinking midnight snack before going to bed will help you sleep. Fruit juice will not burden the stomach, but also can fully supplement vitamins and minerals. Natural fruit juice, which combines flavor, nutrition and health care, is the most promising health food.
