#Medication science ranking # Do not take medicine every day to drink lemon juice can reduce uric acid and cure gout, which is the main content of yesterday's popular science article.
This is unbelievable, a stone stirs up a thousand layers of waves.
People who often drink lemonade have questioned why they often drink it, but whether they always have gout attacks, but they only listen to the doctor who usually drink more soda and do not drink more lemonade.
The most weighty question is that even if lemon juice can lower uric acid and cure gout, do you have evidence? What's at work?
I have to say that these doubts are all justified, and I feel that the responsibility is heavy, and the road to science popularization is far away and necessary.
Therefore, I think it is necessary to clarify this aspect in today's TCM Doctor's Talk Health Original American Article 75.
<h1 class="pgc-h-decimal" data-index="02" data-track="10" What are the nutrients and functional ingredients > lemons? </h1>
Lemon, for the russet family citrus trees evergreen small tree, its fruit has low sugar and high acid aroma and other qualities, so widely loved by people around the world, although native to Southeast Asia, is now the main cultivated fruit tree variety in Europe and the United States.
Lemon is also known as lemon fruit, foreign lemon, mother fruit, etc., the peel surface is yellow, commonly known as lemon yellow, the appearance of the peel is relatively rough, uneven, the fruit shape is oval, the size is different, the average weight is about 80 grams, the peel is thicker, and the juice rate is 30% to 40%.
The functional ingredients in ning lemon are very rich, including flavonoids, citric acid, flavonoids, vitamin A, volatile oils, dietary fiber, pectin, limonin, vitamin C and minerals.
There are many kinds of minerals in lemons, mainly potassium and calcium, but also sodium, zinc, manganese, phosphorus, magnesium, selenium, iron, copper and so on.
Vitamins are the most abundant nutrients in lemons, especially vitamin C, and also contain small amounts of vitamins B1 (thiamine), B2 (riboflavin), B3 (niacin), B6 (pyridoxine), B9 (folic acid) and a very small amount of vitamin A.
<h1 class="pgc-h-decimal" data-index="03" data-track="18" > What ingredients in lemons can lower uric acid and relieve gout? </h1>
Given the long history and wide range of uses of lemons, people are actually very deep about the breadth and depth of their research, but there are not many studies on its effects on gout or uric acid, but they are not nothing.
Because of the relationship between acid and base and gout and uric acid, after some reasoning and research, citric acid is the first substance to enter the researcher's field of vision.
citric acid:
A weak acid, widely found in various vegetables and fruits, because it is first extracted in lemons, so it is called citric acid.
The citric acid contained in lemons, mainly found in the peel and juice, accounts for no more than 10% of the dry weight of lemons, and is the most representative acidic substance in lemons.
It has been suggested that citric acid can alkalize urine and assist in the treatment of uric acid stones. The reason for this is that uric acid crystals are mainly present in acidic environments to form.
The above is the research cognition of domestic scholars, in fact, the University of California, San Diego Health Center also has a similar conclusion, their research believes that lemon juice is rich in potassium and citric acid, both of which can prevent uric acid from forming gout and kidney stones, and the study also confirmed that potassium and citric acid can also prevent the accumulation of too much acid in the body, which can create an alkaline body environment that alkalines the body and blood.
However, the above conclusions have been questioned by later researchers, because their research concluded that the citric acid in lemons does not alkalinize the urine and has no effect on the excretion of uric acid in the body, and the main role is the potassium citrate contained in lemons. (We'll look at this in more detail in tomorrow's content.)
Limonin and coumarin:
Studies of limonin and coumarin on gout or uric acid are not directly evidenced. But both are anti-tumor, antibacterial and antiviral. The antimutagenic effect seems to be related to gout and uric acid lowering.
Lemon and urinary tract stones:
Searching the literature, it is not difficult to find that lemon juice has a certain effect on various stones when some reports are reported.
Some researchers have found that mice are provided with different concentrations of lemon juice, and it turns out that high concentrations of lemon juice effectively reduce the content of stones and calcium, phosphorus, urea nitrogen and creatinine in various parts of the kidney, and the mechanism of action may be that lemon juice can increase the filtration rate of glomeruli and the ability to resist lipid peroxidation.
In foreign studies in the study of potassium citrate provided for patients with hyperuricemia stones, the results confirmed that lemon juice is rich in citrate, which can reduce the concentration of calcium oxalate and calcium phosphate in the urine, thereby inhibiting the occurrence of urinary stones.
The researchers also conducted a similar comparative study of lemon juice and orange juice, and the results showed that lemon juice can inhibit calcium oxalate deposition and form crystals like citrate, but orange juice does not have this effect. It is therefore thought that potassium citrate is the one that acts on the stones in lemon juice, because the orange juice does not contain potassium citrate, but the orange juice contains almost equal amounts of citric acid.
So is it citric acid or potassium citrate that acts on the excretion of uric acid in lemon juice? We'll take a closer look at tomorrow's content.
