[a share from Haimei] does barley leaf really lose weight? The efficacy and taboo of barley leaf. Barley leaf is a Japanese name, Roman for aojiro, is barley seedlings growing to 20-30 cm. If it means young and small, it means the wheat seedling before heading and hardening. It is an alkaline food with high concentration of potassium, phosphorus, vitamin A, vitamin K and other nutrients. It also contains a large amount of dietary fiber, which is helpful to bowel movement and defecation, improve constipation and halitosis. It is mainly suitable for people with insufficient vegetables and fruits. But if you want to eat barley leaves to achieve weight loss effect, this effect is not obvious.
In most people's circle of friends, there will always be one or two friends who are promoting "barley leaf green juice", which claims to improve sub-health status, help detoxification, and lose weight healthily. Is this true?
Does it have any health value? People who eat well and have a balanced diet really don't need to drink it.
Reason 1: the history of Qingzhi is gossip
The history of Qingzhi, which can be found, was invented in 1943 by Japanese military doctor rinro endo. It is said that in his poor diet during the war, he experimented with juicing a variety of vegetables, including not only barley leaves, but also kale and other green vegetables, which cured his son's pneumonia and his wife's nephritis. --However, it was published as an anecdote in kateigaho, a magazine recording Japanese culture, art and lifestyle, and the article was withdrawn in 2007, so it has no reference value.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 of dialysis patients, and the high concentration of vitamin K will weaken the drug effect of patients with circulatory system problems who are taking medicine.

Reason 2: alkaline food is not magical
Barley RUOYE claims to have the greatest effect: "magical alkaline food can improve the sub-health state of acid constitution, which is a universal disease
In Japan, meat is cheaper and vegetables are less and more expensive. In the ordering of various restaurants, the vegetables may be just a handful of seaweed, resulting in a serious shortage of dietary fiber, some water-soluble vitamins and minerals in the diet of the Japanese people. Therefore, green juice, which contains dietary fiber, vitamins, minerals and is affordable to the people, seems to be a little more nutritious than the three meals.
However, the human body produces both acid and alkali in its daily metabolism. It has a strong blood body fluid regulating acid and alkali, which can keep the blood at a weak alkaline level of about 7.4. Once the blood pH changes greatly, it is estimated that the patient will die soon. This product in any food metabolism will not affect the human body at all.

Reason 3: "defecation" is a conceptual pseudoscience
Another claimed effect is: "detoxification. If the sedimented stool in the intestine is not excreted in time, the toxin will be absorbed by the intestinal wall again and enter the blood. Green juice helps to excrete the aged stool. '
However, the concept of "Subian" is made by health care products manufacturers, and there is no definition of this term in regular medical textbooks. There is no evidence to support the claim that "Subian contains toxins and can cause acidosis.".
Reason 4: eat 25 bags a day
Motoya ikeguchi team's research: after adding 3% barley leaf fiber concentrate to the diet of rats, we found that the water content and volume of feces increased, and the defecation time shortened, which seemed to be able to relieve constipation.
However, if converted into human body's intake according to body weight, about 25 packets of commercially available barley leaf meal (1.24g per packet of dietary fiber) are needed a day. According to the manufacturer's recommendation of 2-3 bags per day, it is far from enough.

Reason 5: do you dare to believe that manufacturers do their own experiments?
It's a scientific fact that lower postprandial blood sugar helps to lose weight. The results of Akira Takano's team said: barley leaf can effectively reduce the postprandial blood glucose level of rats. In the subsequent human trials, the recommended dose of barley leaf was used. Taking 1.5g barley leaf powder before meals, the postprandial blood glucose level also decreased. However, the relevant studies are supported by the manufacturers of green juice and published in journals with low scientific influence. Is there any bias in the experiment? Let's feel it for ourselves.
Barley leaf green juice can help people who don't like vegetables or can't have a good meal because of busy work. It can supplement dietary fiber, but it's not as magical as advertising. In fact, as long as we pay more attention to the intake of dietary fiber in our daily diet, slow down gastric emptying, reduce appetite and reduce total energy intake, we will naturally have obvious weight loss effect. Where does the dietary fiber come from?
1. Grain and oil: grain fiber mainly comes from wheat bran, corn, sorghum and rice bran, mainly insoluble in water;
2. Bean fiber: mainly from soybean and other beans, mainly soluble dietary fiber;
3. Mushrooms.
