Can drinking fruit juice or vegetable soup really replace dinner or vegetables and fruits?

Modern people are popular in healthy eating, pursuing natural food without additives, and sometimes paying attention to timeliness. They don't have time to eat a bunch of fruits and vegetables at the same time, so freshly squeezed fruit juice, fruit and vegetable juice and even refined soup have become very popular healthy eating. There are even celebrities who have been promoting health essence soup for many years, and they also take the results of long-term drinking by their families as publicity cases.

However, what is the nutritional value of these drinks that omit the normal cooking process and directly crush the fruits and vegetables on the ground with machines? Can it meet the requirements of maintaining the normal function of the human body, and is it suitable for everyone to switch to drinking to absorb these phytonutrients? I believe it is a question that many people are curious about.

Freshly squeezed juice will lose a lot of nutrients, and the calories are not low, and the risk of obesity will increase by four times. Let's start with freshly squeezed pure juice. If you use factory machines to make juice, you must go through cleaning, peeling, squeezing, pasteurization and other processes during the processing. In the process of sterilization, the instantaneous temperature can reach above 100℃, so the natural vitamin C will be destroyed a lot. The important nutrients in fruits, such as dietary fiber, vitamins, minerals and antioxidants, will also be lost in large quantities. When the juice is made, the vitamin C in the fruit is less than 5%.

If freshly squeezed juice is squeezed at home, although the purity can be guaranteed to reach 100%, the sugar content in it is still a problem that cannot be ignored. For example, the water content of an orange is about 80%, and it takes 5 to 8 oranges to squeeze a cup of 500ml orange juice. Such a glass of orange juice has about 300 to 480 calories, even higher than the same amount of Coca-Cola. About 60% of the calories of sugar will be metabolized in the liver. Most fructose is converted into fat in the liver, which leads to fat accumulation in liver cells and muscle cells, insulin resistance and nonalcoholic fatty liver disease, and then leads to obesity.

A clinical study shows that children who drink juice for breakfast are 1.5 times more likely to be overweight or obese than children who don't drink juice. The American Academy of Pediatrics (AAP) explicitly banned 1 7 children from drinking fruit juice. Clinical research shows that people who drink fruit juice have more than four times the risk of obesity than those who eat fruit.

Cellulose in fresh fruits can prolong digestion time and increase satiety. More importantly, compared with whole fruit, fruit juice has no nutritional advantage. A whole fruit can retain more dietary fiber and nutrition than freshly squeezed fruit juice, and at the same time, the sugar content is much less than that of the same weight fruit juice. In the process of eating fruit, repeated chewing can delay gastrointestinal emptying and enhance satiety. At the same time, because most fruits contain cellulose which is not easy to digest and absorb, it can prolong the digestion time and make people less hungry.

Does the refined prescription soup of fruits and vegetables have magical anti-cancer effect? After talking about pure juice, let's take a look at fruit and vegetable juice or refined soup with fruits, vegetables or whole grains as the staple food. Is there a magical health preservation or even cancer prevention effect?

Opinions from all walks of life are very different on this issue. HEHO once wrote an article "The Prince of Fruit and Vegetable Juice tells you the magical cancer prevention effect after drinking 2 million CC of fruit and vegetable juice". Han Baichang, a professor at Beijing Medical University, said that after drinking fruit and vegetable juice containing 30 ingredients for a week, his weight began to drop, and he lost 3 kilograms in two weeks. Later, I found that the urine became clear, the spots on my face became lighter, my skin became brighter and my spirit became better. He even published a book to publicize that drinking fruit and vegetable juice is one of his "hands for reducing cancer 18", which can bring good things into the body, and various phytochemicals with eight functions are very important, especially for killing cancer cells and inhibiting abnormal vascular proliferation.

Chen Yueqing, a veteran media person, once helped her husband, former Secretary-General of the National Security Council, Su Chi, recuperate with the homemade Whole Foods Essence Soup. As a result, his fatty liver not only disappeared, but his liver was even healthier than before he had liver cancer. Her husband's personal experience made her soup famous for some time and became a fashion.

Indeed, according to clinical research, if you can grind and break the dietary fiber that is not easy to swallow, such as grape skin, pumpkin seeds and burdock, you can greatly increase the intake of dietary fiber. Clinical studies have proved that dietary fiber and various phytochemicals can effectively reduce breast cancer, endometrial cancer and ovarian cancer in men and women, as well as esophageal cancer, gastric cancer and colorectal cancer in the digestive system.

The medical community has negative opinions about whether Jinglitang has special effects, but the medical evaluation of fruit and vegetable juice is not entirely positive. For example, Dr. Jonathan Hall, a consultant at St. Mary's Hospital in London, said that the sugar in fruits and vegetables is called FODMAPs. If fruits and vegetables are made into juice, some people will not be able to digest this sugar, which may lead to symptoms of intestinal dryness, leading to abdominal pain, bloating and diarrhea. Hall also said that the health benefits of fruit and vegetable juice are not so obvious. "There is no logical reason or any evidence that drinking fruit and vegetable juice is better than eating vegetables and fruits. Hall said.

In addition, Willand, a professor of diabetes and nutrition at King's College London, England, also doubted the substantial health benefits of fruit and vegetable juice. He said that there is no systematic and strong evidence to support this statement, especially compared with eating fruits and vegetables directly to balance nutrition.

Some people are not suitable for drinking fruit and vegetable soup. Whether it is the personal experience of cancer patients or their families, or the research and analysis of scholars and experts, it is at least confirmed that fruit and vegetable juice or soup is not a healthy conditioning drink. However, while promoting the benefits of drinking, we should also remind some people that it is not suitable to use fruit and vegetable soup or juice for health preservation, or we should be especially careful in the process of conditioning. For example, cancer patients who are undergoing chemotherapy and radiotherapy, or pregnant women and children under 7 years old, it is best to blanch vegetables, disinfect them first and then juice them. According to clinical statistics, at least 3 1 person in the United States was infected with Salmonella after eating alfalfa sprouts in 2009. These people have low resistance and it is not recommended to eat raw.

In addition, nutritionists also remind people with high uric acid or gout that when making fruit and vegetable juice, the amount of beans should be controlled in the selection of ingredients to avoid excessive intake of protein, which will lead to abnormal metabolism and increase uric acid value. As for patients with chronic renal failure and renal dialysis, it is even more necessary to avoid drinking fruit and vegetable Jingli decoction. Because Jinglitang contains a lot of ingredients with high potassium and phosphorus content, if you want to drink it, you must first discuss the ingredients and intake with the dietitian.
