purine is a substance existing in the nucleus, so basically any food contains purine to some extent. Generally, the more cells in food, the higher the purine content. On the other hand, foods that contain only one cell, such as eggs, have very low purine levels, no matter how big they are.

Of course, you are not a fairy, so you can't calculate the purine content by counting the number of cells in food. What should I do?

Your taste instinct may help you: one of the characteristics of high-purine food is "freshness", and the more delicious the food, the higher the purine content may be. In fact, purine itself is also one of the indicators of freshness.

speaking of which, you may have been able to guess a thing or two. Yes, that's right. Animal offal, various seafood and thick soup gravy are all "classic" foods with high purine content.

2. According to science, the purine content of food is carefully classified

but it is not always reliable. We need scientific standards to classify the purine level of food in detail:

Category I: high purine food (containing 1-1 mg of purine per 1 g)

Mainly animal viscera (especially liver), thick soup and gravy (hot pot) and fish eggs.

category ii: moderate purine food (containing 75–1mg of purine per 1 g)

freshwater fish such as perch, marine fish such as cod, shellfish, eel and eel, smoked ham, pork, beef, rabbit meat, venison liver, poultry and so on.

the third category: foods with low purine content (every 1 g of food contains purine <: 75 mg)

herring, tuna, white fish, lobster, crab, oyster, ham, mutton, chicken, cereal, bread, coarse grains, asparagus, cauliflower, green beans, peas, kidney beans, spinach, dried beans, tofu and so on.

the fourth category: extremely low purine food

all kinds of fruits, dried fruits, sugar, eggs, milk, soft drinks, tea, coffee, chocolate, all kinds of oils, peanut butter, jam and so on.

3. Food choices of gout patients

(1) Food choices and taboos

Patients with gout and hyperuricemia should concentrate on the third and fourth kinds of food in their daily diet, while the first kind of food should be taboo.

(2) Choice between animal and plant foods

In addition, recent studies have found that animal purines are more harmful than plant purines in foods with the same purine level, and mushrooms are classified as plant purines although they are not plants. Another epidemiological study even thinks that plant purine seems harmless, on the contrary, it is beneficial, but this has not been recognized by international authorities and needs careful observation.

(3) High-sugar foods are worthy of vigilance

It is important to point out that the fourth kind of extremely low-purine foods seem to be very safe, but the high-sugar foods contained in them need special vigilance.

Although high-sugar foods and drinks are hardly a concern from the purine point of view, recent studies have suggested that high-sugar also has an amazing effect of raising blood uric acid level-the more sugar is ingested, the higher the blood uric acid level will be. The underlying mechanism of this phenomenon is not clear at present, but it is enough to remind myself to reduce the intake of high-sugar foods, especially carbonated drinks and other fruit juice soft drinks containing a lot of high fructose syrup in daily life.

(4) Actual intake

Another thing that needs to be considered is that although the purine level in food is calculated by the amount of purine per 1 g, in the operation of practical health advice, we should not only examine the influence of a certain food on gout by numerical comparison, but also consider the actual intake of this food in catering.

this is more prominent in another big category of food: alcoholic beverages.

gout, can you drink alcoholic beverages

The purine content in alcoholic beverages is calculated by how many milligrams of purine are contained in each 1ml. According to the Japanese public welfare consortium legal person? Information of gout consortium, The purine content of the most common alcoholic beverages in social catering is:

Japanese shochu: almost zero mg/1ml

whisky: .1mg/1ml

brandy: .4mg/1ml

Japanese sake: 1.2mg/1ml

wine: .4mg/1ml. 1ml

Shaoxing wine (yellow rice wine): 11.6mg/1ml

From this, it can be seen that high-alcohol liquor generally has no problem with purine, and wine is fine, but beer and yellow rice wine are "forbidden areas" for high-risk people. Especially beer, although it is not as good as yellow rice wine in terms of unit value, because the alcohol content of beer is far less than that of yellow rice wine, and it contains carbonated gas, it is particularly refreshing. When it is compared with visceral meat and seafood, it is very delicious, and it is often impossible to drink one cup after another, which eventually leads to the overall purine intake is often much higher than that of yellow rice wine.

By the way, the incidence of gout in Qingdao ranks first in China, among which the incidence of gout in adult males is as high as 2.2%, which is much higher than .96% in China. One of the reasons is that Qingdao is near the sea and rich in seafood, and Qingdao men especially like beer and seafood to eat.

Then the question comes: Is it just because beer and seafood are high purine foods, and the total purine content together is too high?

no.

Of course, it is true that the total purine is higher, but there is another point that many people may not think: alcohol will increase the blood lactic acid concentration in the process of metabolism in the human body, and the latter will inhibit the uric acid excretion in the kidney. Others suffer from ketosis due to excessive Binge Drinking, and uric acid excretion is more inhibited. Although the mechanism of alcohol on serum uric acid needs to be further studied, the role of alcohol in fueling high purine foods has attracted enough attention.

gout, other lifestyle interventions

are more important in two aspects.

1. greatly increase the total daily drinking water, and it is better to drink a small amount and many times at a time. Don't wait until you feel thirsty.

The reason is simple: promoting uric acid excretion.

But we should also pay attention to the methods:

(1) Drink pure water instead of soft drinks or coffee.

(2) Don't drink sea water before going to bed, so as not to increase the burden on the kidneys during sleep.

2. Insist on moderate exercise (but don't overdo it).

Exercise can also promote uric acid excretion, and at the same time prevent another risk factor of gout and hyperuricemia: obesity.

finally, once again, keep your mouth shut.
