Stale Fish
Many people go to the market or buy fish from small vendors to get a cheaper price. However, cheap fish usually does not guarantee quality. They can be stale and not fresh anymore.
Dr. Chen Shizhang (Huu An Hospital, Beijing, China) said that when buying fish, it is important to choose fresh ones with clear eyes, intact eyeballs, full and slightly bulging bellies. Fresh fish will be sweet-smelling and the most nutritious. But if the fish is stale, the meat will become soft, and the vitamins and minerals will gradually be lost. Furthermore, when the fish dies, bacteria in it will grow rapidly, causing digestive problems if consumed.
When going to the market, if you see fish that are no longer moving but have a very swollen abdomen, do not buy them because they may have been dead for a long time, and the internal organs may be damaged, causing the abdomen to swell.
Abnormally Large Freshwater Fish
Many people like to buy large fish because they think they will be better and have more meat. However, for freshwater fish, if they are abnormally large, it is important to reconsider. Normally, a freshwater fish only weighs about 2-3kg and is not too big. But if you see someone selling abnormally large freshwater fish, weighing tens of kilograms, do not rush to buy them as they may be farmed fish instead of natural fish. They may even have been injected with growth hormones. Consuming such fish poses potential risks to the health of young children. Therefore, parents should avoid buying them.
Salted Fish
Dried and salted fish have the common characteristic of being salty and very savory. Young children love them. However, due to the process of salting and drying, most of the nutrients in the fish are lost, mainly leaving a large amount of salt. Regularly consuming salted fish will burden the liver and kidneys of children and may also harm their blood vessels.
In addition, salted fish contains a lot of nitrites. Nitrites, when in the human body, form nitrosamines, powerful carcinogens that can cause serious damage to the liver of young children.
Raw Fish
Many people believe that raw fish is delicious and has high nutritional value, so they feed it to young children. However, Dr. Wang Bojun, the chief digestive specialist at Ninh Ba Medical University Hospital, said that if raw fish is not carefully selected and prepared, it can contain many parasites and bacteria. In addition, young children have relatively weak immune systems and resistance, making them susceptible to illness from consuming raw food.
Fish with Strange Smell
If fish live in such an environment for a long time, it will lead to an accumulation of heavy metals and other toxic substances in the body. Consuming too much will exceed the standard intake of harmful substances into the body. This will make children feel nauseous, have headaches, damage the digestive system, and even threaten their lives.
