Is what barley leafy juice?
The manufacturer’s publicity materials read: Barley Ruoye Green Juice (Japanese name, Roman pronunciation is Aojiru), the raw material is the seedlings of barley growing to 20 ~ 30cm. Barley Ruoye [Ruo] means young, so to put it bluntly, the wheat seedlings before wheat heading and growing into hard stems are essentially grass. Mix the grass into pulp, grind it into powder, soak it in water, and make green juice.
In Taiwan and other areas, it is also called wheat straw juice.
Does this thing have any health care value? In my opinion, people who eat well and eat a balanced diet do not need to drink.
Reason 1: Green Juice History Is Gossip and Anecdote
The history of green juice that can be found was invented by Japanese military doctor Renlang Endo in 1943. It is said that he tested a variety of vegetable juicing in a barren diet during the war, including not only barley leaves but also green vegetables such as kale, which cured his son’s pneumonia and his wife’s nephritis.
However, this is published as anecdotes in magazines < > that record Japanese culture, art and lifestyle. And the article was withdrawn in 2007, so it has no reference value. Later scientists analyzed that the high concentration of potassium, phosphorus and vitamin A in green juice will aggravate the disease condition for dialysis patients, and the high concentration of vitamin K will also weaken the drug power for patients with circulatory system problems who are taking drugs.
Reason 2: [Alkaline Food] Not Magic
Barley Ruoye claims the greatest effect is:
[Magic alkaline food] can improve the sub-health state of [acidic constitution], which is the source of all diseases.
Both acid and alkali are produced in daily metabolism. The human body already has strong blood and body fluids to regulate acid and alkali, which can keep the blood at a weakly alkaline level of about 7.4. Once the pH value of the blood changes greatly, it is estimated that life will soon be over. This product in any food metabolism will not affect the human body at all.
Reason 3: Pseudoscience of the Concept of “Pai Su Shi”
Another claimed effect is:
Detoxification, if the stool deposited in the intestinal tract is not discharged in time, the toxin will be absorbed by the intestinal wall again and enter the blood. Green juice is helpful to discharge the aged stool.
The concept of “excrement” was created by health care products manufacturers, and there is no definition of this term in formal medical textbooks. The so-called statement that excrement contains toxins that will cause acidosis in the body has no basis in what.
Only constipation is really not a good thing in what. It will cause some anorectal diseases and even gastrointestinal neurological dysfunction. However, once the human body has a certain amount of feces, it will report to the brain that it needs defecation. How can there be so many aged feces?
Reason 4: You have to eat 25 packs a day! Ha ha
Research by Motoya Ikeguchi’s team: After adding 3% barley leaf concentrated fiber to the diet of rats, it was found that the fecal water content increased, the volume increased, and the defecation time shortened, which did seem to relieve constipation. However, if converted into human intake by body weight, about 25 packs of commercially available barley leaf powder (1.24 g per pack of dietary fiber) were needed a day.
However, manufacturers recommend 2-3 packs per day, which is far from enough.
Reason 5: Manufacturers do their own experiments, and the credibility is uncertain.
It is a scientific fact that lower postprandial blood sugar is helpful to lose weight. The results of Akira Takano’s team said that barley leaves can effectively reduce the postprandial blood sugar level of rats. Subsequent human tests used the manufacturer’s recommended dose, and 1.5 g barley leaves powder before meals also reduced the postprandial blood sugar level.
However, the relevant research was completed with the support of the manufacturers of green juice and published in publications with low scientific influence. Is there any bias in the experiment? Let’s feel it for ourselves.
Reason 6: Other studies are still shallow and inconclusive.
A study by Taiwan University of Traditional Chinese Medicine believes that the combination of green juice with antioxidant vitamin C and vitamin E has the risk of preventing angiopathy in patients with type 2 diabetes. The principle is still based on the theory of free radicals, which is somewhat outdated.
Others believe that the fermented green juice may contain some prebiotics, which will stimulate butyrate on the inner wall of intestinal canal to produce flora beneficial to digestive tract, and has certain adjuvant therapeutic effect on ulcerative colitis. However, the research level is far from the depth of Phase III clinical trials, and no conclusion has been reached yet.
Reason 7: Green juice makes up for the problem of expensive vegetables in Japan,
The effect of green juice sounds a bit chicken ribs, but why is it so popular in Japan?
Meat is cheaper in Japan, Vegetables are few in variety and expensive. Among the regular meals in various restaurants, The vegetable may be a pinch of seaweed, resulting in a serious shortage of dietary fiber and some water-soluble vitamins and minerals in the Japanese people’s diet. Therefore, green juice containing dietary fiber, vitamins and minerals, and the price is also close to the people, seems to have become a nutrient that can be slightly supplemented in addition to the daily three meals.
In China, the price of vegetables is far lower than that of meat. The cost of drinking green juice is higher than that of eating fresh vegetables directly. As long as the daily diet [full of green], there is no need to drink extra green juice.
Reason 8: It’s hard to drink,
Green juice is generally recognized as difficult to drink and is usually used as a punishment tool in Japanese TV variety shows. Let’s be fine, why should we spend money on the crime?
