Black fungus is rich in nutritional value and various life elements necessary for the human body. Black fungus is rich in potassium, phosphorus, magnesium, and calcium. The calcium content is 100 grams to 34 mg, which is better than many vegetables. Black fungus is also rich in vitamin E, which can protect the reproductive system. It is also an antioxidant element that can protect blood vessels and resist aging. Black fungus is rich in dietary fiber, which can relieve constipation, inhibit the absorption of fat, cholesterol and sugar, and is very useful for preventing chronic diseases. The most noteworthy thing is the "fungus polysaccharide" in the fungus. Fungus polysaccharides can reduce blood viscosity and are very useful in preventing atherosclerosis and thrombosis. Fungus polysaccharides help prevent cardiovascular and cerebrovascular diseases and help uric acid metabolism, which is very beneficial to patients with gout/hyperuricemia.

Onions are also low-purine foods, rich in dietary fiber, and can stabilize blood lipids and blood sugar. Onions are very rich in potassium, up to 740 mg in 100 grams, which is very useful in preventing high blood pressure caused by increased extravascular osmotic pressure. Onions also contain a variety of minerals, including very rich calcium content, which can be used as an excellent food to supplement calcium. The volatile smell in onions can sterilize and disinfect, inhibit various cocci and bacilli, and protect the health of the stomach. Selenium in onions can also prevent vascular aging and cardiovascular and cerebrovascular diseases. They are an excellent food for high school students with hyperuricemia. Friends with hyperuricemia should choose low-purine foods every day. Fruits, vegetables, eggs, nuts, staple foods, and cooking oils can all be consumed normally. It should be noted that the amount of meat needs to be moderate, and it is best to choose lean meat.

It is best not to eat when gout is common when you are not stable. Some fish and shrimp have higher purine content, and some are in the middle. Grass shrimp has higher purine content, while lobster and squid have lower purine content, so they can be eaten in small amounts. Unlike animal purines, purines in plants are also inhibited by dietary fiber, tannins, etc. And they’re not very absorbent. And plant-based foods help uric acid excretion and help prevent gout. Uric acid is a metabolite of purine. When purine metabolism is disrupted in the body, uric acid will increase. Most purines come from metabolism, and a small amount comes from food. Because metabolic disorders are difficult to improve, diet has a great impact on purine and uric acid. According to the purine content, foods can be divided into three categories: low purine foods (containing less than 50 mg per 100 g of food), medium purine foods (containing 50 to 150 mg per 100 g of food), and high purine foods (containing less than 50 mg per 100 g of food). 150 mg or more).

People with high uric acid should avoid high-purine foods, eat moderate-purine foods, and eat more low-purine foods. Therefore, whether people with high uric acid can eat black fungus and onions depends on the purine content. The purine content of dried black fungus is as high as 160mg/100g, but no one will eat dried black fungus. After soaking, the purine content of black fungus, which absorbs a large amount of water, is reduced to about 10~20mg/100g, making it a suitable low-purine food. The purine content of onions is also very low, much less than 50mg, and it is also a typical low-purine food. Therefore, people with high uric acid can safely eat black fungus and onions. Not only can they be eaten, but people with high uric acid should also eat these two vegetables regularly. Black fungus is rich in dietary fiber, vitamins, minerals and polysaccharides. Onions are rich in sulfur-containing compounds, vitamins and minerals, and are even the only vegetable to contain prostaglandin A, which dilates blood vessels. So both vegetables are healthy foods. Eating them regularly is beneficial to health in many ways and can also help improve purine metabolism disorders.
