High purines can easily induce gout! Don't exceed one or two halves of aquatic products every day

Aquatic products are a good source of high-quality protein and rich in fatty acids that are beneficial to health. Therefore, many people think that it is okay to eat more aquatic products, but in fact, it is not.

First, protein is mainly metabolized by the kidneys, and excessive intake of aquatic products can easily increase the burden on the kidneys. Especially for patients with kidney disease, it is necessary to strictly control protein intake, otherwise the condition will be aggravated.

Second, for patients with gout or hyperuricemia, the daily intake of aquatic products also needs to be strictly controlled. Gout is a disorder caused by a disorder of purine metabolism and/or decreased uric acid excretion. The final product of purine metabolism in the human body is uric acid, which is mainly excreted through the kidneys.In patients with gout or hyperuricemia, the onset is closely related to diet. Studies have shown that the total purine content of aquatic products is slightly higher than that of livestock and poultry meat. Boiling and rinsing can effectively reduce the purine content in food, but barbecue causes food moisture loss and purine content becomes high. Therefore, when cooking aquatic products, it is recommended to boil them in water or boil them before cooking.

Third, the rapid development of modern industry and the continuous deterioration of the fishing environment have polluted aquatic organisms and affected the quality of aquatic products. Heavy metals, fishery and pesticide residues ingested by aquatic organisms from the environment are enriched by higher folds in higher organisms through bioaccumulation and biomagnification of the food chain. By eating, these residues enter certain organs of the human body, which in turn causes chronic poisoning. In particular, crustaceans and shellfish aquatic products are more likely to accumulate heavy metals and other toxic substances due to their low habitat and filter feeding habits.

Fourth, the presence of pathogenic microorganisms in aquatic products also deserves everyone's attention. The pathogenic microorganisms in aquatic products include the following categories: first, the original bacteria of aquatic products themselves, which are widely distributed in water, such as botulinum toxin, listeria, Vibrio cholerae, Vibrio parahaemolyticus, etc.; The second is human-polluted bacteria, which mainly exist in the intestinal tract of humans and animals and in the water environment contaminated by feces, such as Salmonella, Shigella, Escherichia coli and Staphylococcus aureus; In addition, it also includes a class of viruses, mainly bivalve molluscs as vectors, such as hepatitis A virus, novovirus, etc.Pathogenic microorganisms can cause harm to people through aquatic products, which are manifested as gastroenteritis, diarrhea, fever, vomiting, sepsis, dysentery and other major symptoms.

In addition, foodborne parasitic diseases caused by aquatic products have been reported frequently, which is closely related to the consumption of raw aquatic products contaminated with parasites. If raw or undercooked freshwater fish and shrimp with cysts are eaten, adult liver flukes may parasitize the bile ducts in the human liver, resulting in liver fluke. Patients usually present with fever, fatigue, jaundice, liver pain, hepatomegaly and tenderness, and in severe cases, biliary colic and obstructive jaundice.

How much aquatic products should I consume per day? The "Dietary Guidelines for Chinese Residents (2016)" recommends that normal people recommend a daily intake of 40~75 grams of aquatic products, which is equivalent to a palm-sized fish piece or 3~5 medium-sized shrimps.In other words, the daily intake of aquatic products should be controlled within one or two halves. Aquatic products should be heated until they are fully cooked, and knives and cutting boards that have been processed for fresh aquatic products are best cleaned and disinfected before use. Once you have symptoms such as cough, liver pain, and fever after eating aquatic products, especially raw aquatic products, you should go to the hospital for examination in time.
