Today, gout has become a common metabolic syndrome after diabetes in China. Gout is a group of clinical syndromes in which purine metabolism disorder leads to the increase of blood uric acid level and the deposition of urate crystals in tissues or organs. In order to avoid the recurrence of gout, many patients who have experienced pain and suffering choose to avoid it. Not only said goodbye to big fish and meat, but even tofu and high purine vegetables. Is it true that gout patients will live a life of "eating bran and swallowing vegetables" from now on? The lifestyle management of gout patients is indeed important, but we should also pay attention to science. Today, based on clinical experience and relevant literature, rheumatic immunologists will help you sort out the common misunderstandings of gout patients in diet management. Myth: high purine vegetables can't be eaten Some vegetables such as lettuce, spinach, mushrooms, green beans, cauliflower and other purine content is high, leading to gout patients dare not eat, worried about inducing the onset of gout. In fact, vegetables are alkaline food and rich in vitamin C, which is a protective factor for gout. Therefore, high purine vegetables will not increase the risk of gout, so there is no need for strict restrictions. Misunderstanding: no more luck with wine and meat The intervention of gout patients' lifestyle runs through the whole process, and the requirements for diet in different periods of the disease are different: in the acute stage of gout attack, the body is in the vulnerable stage, so the intake of purine should be strictly controlled and away from alcohol to avoid aggravating the symptoms of acute gouty arthritis. In the intermittent period, because the level of blood uric acid is higher than that in the acute period, the focus of treatment is to control the standard with uric acid lowering drugs, and the dietary control can be relaxed appropriately. For example, seafood with medium purine content such as shrimp, crab and squid and beef, sheep and pork can be eaten in limited quantities. Myth: gout has to eat more coarse grain Due to the relatively high content of purine in grain husk, the intake as a staple food is large. Excessive intake will increase the production of blood uric acid. Especially in the period of gout attack, do not eat coarse grains with high purine content. In addition, in the daily diet, it is suggested that the staple food of gout patients is mainly fine grain, and coarse grains with low purine content, such as corn and millet, can be selectively ingested. Misunderstanding: high purine content of bean products should be fasting Beans and bean products do contain high purines. Earlier views suggested that patients with gout should limit the intake of beans and bean products. Later, research found that some components in beans and bean products can promote the excretion of uric acid, and once encouraged gout patients to eat beans and bean products. The latest research tends to neither encourage nor limit the intake of beans and bean products, just eat them normally. Myth: seafood can't be touched The purine content of different seafood varies greatly. For example, the purine content of jellyfish and sea cucumber is even lower than that of some green vegetables. Therefore, sea cucumber, jellyfish and seaweed, which are low purine seafood, can be eaten by gout patients. In addition, the intake requirements of seafood are also different in different periods of disease. Patients with acute stage and uncontrolled serum uric acid should absolutely abstain from seafood with high purine. However, patients who have reached the standard in intermittent period and blood uric acid control can selectively eat seafood with medium and low purine content, such as salmon, saury and so on. Misunderstanding: the more "cruel" dietary control, the better Overeating can induce acute attack of gout. Controlling diet can reduce body weight and uric acid. In addition, some patients are unwilling to take oral drugs to reduce uric acid, so they take diet to treat gout. Proper diet control is indeed beneficial to gout, but excessive diet will produce acidic metabolites such as ketones, which will lead to the increase of blood uric acid and even induce the acute attack of gouty arthritis. Therefore, gout patients should not go on an excessive diet. They should go on a moderate diet and have balanced nutrition according to the daily calories needed. Myth: fruits with low purine can be eaten casually Fruit is the food with the lowest purine content, but gout patients can't eat too much because of the low purine content of fruit, especially a large amount of fruit in a short time. Because fructose content in fruits is high, fructose will increase the level of serum uric acid, and increase the risk of obesity, dyslipidemia, diabetes and so on. Therefore, gout patients should selectively eat fruits. They can eat more fruits with low fructose content and should not eat too much fruits with high fructose content. Myth: drinks can replace water We encourage gout patients to drink more water and maintain a daily urine volume of more than 2000ml. However, some patients use sugary drinks instead of water, which can also meet the requirements of more than 2000ml urine volume per day. This is wrong because the sweetener in sugary drinks is mostly high fructose syrup, also known as fructose syrup. The increase of intake will not only cause more uric acid production, aggravate the disease, but also lead to the risk of diabetes, coronary heart disease and cancer. (outlook new era)
