Gout is a complex arthritis associated with uric acid crystal deposition.
Therefore, hyperuricemia is considered a precursor to gout attacks.
It is known that eating foods with high purine compounds can increase blood uric acid levels, which can promote and exacerbate gout attacks.
Therefore, various guidelines on gout suggest that diet is an important part of the management of high uric acid and gout.
For example, it is recommended to strictly control foods containing a lot of purines such as chicken liver, meat and so on.
However, there are disagreements regarding the purine content of other specific foods and whether they are suitable for patients with hyperuricemia and gout.
peanuts are a typical example.
Is the peanut purine content high?
There are three different theories about the purine content of peanuts:
Some people say that peanuts have high purine content and are not suitable for hyperuricemia. Food for patients with disease and gout;
Some people say that peanut has a medium purine content of 96.3mg/100g, which is not suitable for patients with gout attacks. However, patients with hyperuricemia and gout in remission can be consumed;
Some people say that peanut purine content is low to medium level, 79mg/100g; in addition, it contains fatty acids with anti-inflammatory properties. Foods that can benefit gout patients.
In this way, many readers are faced with an old difficult question: Who does
listen to?
How many purines does peanut contain?
The saying that the purine content of peanuts is 96.3mg/100g is mainly popular in China, and 79mg/100g is spread abroad.
Which statement is more accurate and true?
We might as well look for the answer from the published medical literature.
Because the data circulating in the market refers to the total purine content of food.
However, we know that total purine includes several forms, and their effects on serum uric acid concentration are different.
Hypoxanthine, hypoxanthine nucleotide, adenine, adenine nucleotide, and guanine nucleotide can increase the blood uric acid concentration of people with normal blood uric acid, hyperuricemia and gout patients.
Among them, hypoxanthine and hypoxanthine nucleotides (metabolic to hypoxanthine) have the most significant effect on blood uric acid; adenine, which is present in nucleic acid, has a weak effect on blood uric acid.
Interestingly, there has been no report that guanine can change serum uric acid levels or urine uric acid excretion, that is, guanine in food may not increase blood uric acid levels.
In view of the different effects of different forms of purines on the metabolism of uric acid, some scientific researches also convert the total purines in food into uric acid equivalent for labeling.
So, what kinds of peanuts and how many purines do they contain?
In a data involving 270 kinds of food purine content high performance liquid chromatography (HPLC) analysis, peanuts contain adenine, guanine, hypoxanthine, xanthine, total purine, and uric acid equivalent values respectively They are 18.9, 28.6, 0.0, 1.6, 49.1, and 57.1 mg/100g.
In other words, the total purine content of peanuts is less than 50mg/100g, which is a very low purine content food.
Moreover, almost all of them are guanine and adenine, mainly guanine, which does not have the effect of raising blood uric acid.
Therefore, in theory, peanuts are a kind of nut (although they belong toThe fruit of legumes) is considered to be a good source of protein and essential fatty acids for gout patients. Not only can gout patients eat, but it is also a recommended food.
"Do not look at the advertisement to see the effect"
Peanuts are the recommended food for gout patients. After all, this is only a theoretical presumption. What is the actual effect of eating peanuts on blood uric acid?
An analysis of the effects of 63 diets and genetic genes on blood uric acid levels published in 2018 found that peanuts are second only to 脱脂奶, and eggs, brown bread and cold-foamed oatmeal are the most significantly reduced. Blood uric acid food.
Of course, other nuts are also recommended foods for patients with hyperuricemia and gout. The purine content is lower than that of peanuts, even though it reduces uric acid Not as good as peanuts.
