About Purine Myths

Myth 1: Vegetables are low-purine foods, and gout patients do not need to limit them. Many people believe that vegetables have low purine content and will not induce gout, so there is no need to limit them.

Compared with animal foods such as offal, seafood, and broth, the purine content of vegetables is generally lower, but the purine content of some vegetables is not low, such as lentils, asparagus, seaweed, Bean sprouts, etc. It is one-sided for gout patients to insist on being vegetarian instead of meat. During an acute attack of gout, you should also try to avoid eating the above-mentioned vegetables with high purine content. During the remission period, reduce the frequency and amount of food you eat. ?

Myth 2: Soybeans contain high purine content, so gout patients cannot eat soy products. The purine content of dry beans (soybeans, black beans, mung beans, red beans, etc.) is indeed relatively high, but because water-soluble purines are lost during processing, when soybeans are processed into tofu and tofu skin, their purine content drops significantly.

During the gout remission period, it is okay to consume soy products in moderation. It is recommended that the order of choosing beans and soy products is tofu, dried tofu, soy milk, and whole beans. The intake should also be gradually increased in this order. reduce. ?

Myth 3: Beer contains a lot of purine, and drinking other alcoholic drinks has no effect on uric acid. The main component of alcohol is ethanol, which can cause the accumulation of lactic acid and ketones in the body and competitively inhibit the excretion of uric acid. Therefore, excessive drinking at one time can increase blood uric acid and induce gout attacks.

As long as you drink alcohol regularly, whether it is beer, white wine or red wine, it will accelerate the synthesis of purine, leading to hyperuricemia and increased uric acid excretion. If you drink high-purine, high-protein, and high-fat foods at the same time, It is more likely to cause acute attacks of gout, which is not uncommon in clinical practice. Therefore, gout patients are advised to stay away from alcohol. ?

Myth 4: In order to reduce purine intake, gout patients should eat as little as possible. When gout patients learn that overeating can trigger gout attacks, many patients resort to dieting. Since body mass index is positively correlated with hyperuricemia, obese people should limit their total energy intake, but this should be done gradually and not too hastily.

Excessive hunger will cause an increase in ketone bodies in the body, inhibit the excretion of uric acid from the renal tubules, reduce uric acid excretion, and induce an acute attack of gout. ?
