Some precautions to take when eating jellyfish
You can enjoy the great benefits of jellyfish, but first, make sure to prepare and use it properly! Here are some precautions to take when eating jellyfish after you understand its nutritional content.

Some notes when eating jellyfish.
Avoid using fresh jellyfish in your diet: Jellyfish will decompose within a few hours and become toxic. Therefore, experts always encourage the use of jellyfish in dried or soaked form.
How to choose jellyfish: The color of jellyfish is an important factor when buying to ensure safety when eating sea jellyfish. Freshly processed jellyfish is usually milk white, and it will slowly turn pale yellow after a while. When the jellyfish turns brown, it means it is spoiled and unsafe for consumption.
Preparation and preservation: You should only eat jellyfish when it has been thoroughly cleaned and stored properly. Then, jellyfish will have little or no signs of dangerous bacterial infection or other harmful pathogens.
For fresh jellyfish, you should clean it and soak it in saltwater with vinegar. During the soaking process, you should change the water 3 times, adding the same amount of salt and vinegar each time. When the jellyfish meat turns red or light yellow, you need to remove the jellyfish and soak it in cold water for about 2 hours. Don’t forget to rinse it again with water, drain it, and then cut it into bite-sized pieces.
For dried jellyfish, you can prepare it by soaking it in water with lime juice for 4-5 hours or overnight. You don’t need to soak the jellyfish for too long as it will cause the jellyfish meat to lose a lot of water, shrink, and become dry when eaten.
Who should limit eating jellyfish?
Although jellyfish contains many nutrients that are beneficial to health, if you belong to one of the following groups, you should limit your consumption of jellyfish to ensure absolute safety.
