Jellyfish Health Benefits, Nutrients, Side Effects, Recipes, and More

Jellyfish are free-swimming marine organisms with tentacles and umbrella-shaped gelatinous bodies. They have a basic body structure with no brain, lungs, or intestines. They do, however, have a well-organized tissue system.

Jellyfish are not fish, but rather planktons. Fish, in general, are animals that live in water and breathe through gills. Jellyfish, on the other hand, are invertebrates with no backbones that breathe through membranes.

Jellyfish are the oldest multicellular organisms known to science. They’ve been around for about 500 million years. Furthermore, they live in every ocean and are invasive in some areas. They can live for up to 30 years.

They flourish in both cold and warm deep water, as well as along the coast. Jellyfish come in a variety of colours, including pink, yellow, blue, and purple, as well as clear and luminescent varieties.

Jellyfish tentacles contain minute sting cells (nematocysts). These cells carry venom, a toxic toxin that jellyfish use to protect themselves. Humans, on the other hand, may suffer extreme pain from stings. When stung by a lethal or venomous species, it can be fatal. They do not, however, assault humans on purpose.

The majority of stings are caused by coming into contact with a jellyfish by unintentionally. Stings are a protective technique used to paralyse their victim. However, the advantages of these gelatinous ancient animals go beyond a stinging experience. They can be used in a variety of ways.

Certain culinary traditions include jellyfish in their dishes. They are regarded a delicacy in Asian cuisines, particularly Chinese and Japanese. Jellyfish, according to Australians, is a proteinaceous, low-calorie sustainable diet.

Jellyfish Nutritional Values

Jellyfish have a high nutritional value. They are low in calories and high in critical elements, antioxidants, minerals, and other essential nutrients. [1]

1 cup (58 grammes) dried jellyfish contains:

  • 21 calories
  • 3 gramme protein
  • 1 gramme of fat
  • 45 percent of the Daily Value for Selenium (DV)
  • 10% of the DV for choline
  • 7 percent of the DV for iron

Jellyfish also contain suitable levels of calcium, magnesium, and phosphorus. It also contains polyunsaturated fats such as Omega 3 and Omega 6 fatty acids, as well as antioxidants such as polyphenols.

Jellyfish Health Benefits

The majority of jellyfish species are edible and high in nutrients. They are low in calories and high in antioxidants, which protect cells from damage. Many diseases can be caused by radical cell damage.

Furthermore, the presence of omega-3 fatty acids makes them better eating choices. This is due to the fact that omega-3 fatty acids reduce fat buildup along artery walls and so aid in the prevention of heart disease.

Let’s take a closer look at the health benefits of jellyfish.

Assists with Weight Management

Jellyfish are low in carbs and calories. As a result, jellyfish are an excellent choice for a weight-loss diet.

Furthermore, it is a fantastic source of protein, which aids in the maintenance of healthy muscles on a diet. It is also high in amino acids, which are necessary for cell growth and repair.

Preventing Brain-Connected Disorders

DNA synthesis, fat synthesis, transport, and metabolism are all part of our metabolism process.

Choline, a calcium-binding protein found in jellyfish, is vital in several stages of cell metabolism. Normally, the brain synthesises choline on its own. It does, however, deteriorate with age.

Choline reduces the risk of developing age-related brain illnesses such as Alzheimer’s and dementia. It also aids in the improvement of brain function. Antioxidants protect cells from oxidative stress. It is the underlying cause of brain illnesses such as Alzheimer’s. Furthermore, selenium decreases or prevents anxiety symptoms.

According to research, the protein present in jellyfish is neuroprotective. It has the potential to effectively cure neurodegenerative disorders.

Encourage Cognitive Behavior

Jellyfish amino acids and protein promote nerve cell renewal.

Furthermore, the calcium-binding protein and antioxidant characteristics improve cognitive performance. It also regulates and alleviates the symptoms of dementia, including memory loss.

Reduces skin ageing and improves skin health

Jellyfish have beneficial restorative qualities. Jellyfish contain choline, which aids in cell repair and regeneration. Furthermore, the collagen component promotes firm and young skin. Antioxidant qualities lessen oxidative stress, which protects cells from damage.

These qualities may aid in the prevention of indications of ageing. According to one study, a hydrolyzed version of collagen is a unique anti-photoaging agent that protects against UV-induced damage. It also plays an important function in wound healing.

The human body produces collagen through the metabolism of vitamin C. Jellyfish, on the other hand, naturally contain collagen. It is a key component of skin health and aids in the preservation of skin suppleness regardless of age.

It also controls skin cell regeneration, giving the skin a firm and youthful appearance. As a result of its rejuvenating characteristics, the cosmetic industry incorporates it into their products. It’s included in a lot of drugs, especially ones for wound healing and reconstruction.

It protects the heart’s health

Polyunsaturated fatty acids (PUFAs) and omega-3 fatty acids are found in jellyfish. They aid in the reduction of LDL (bad cholesterol) and the elevation of HDL levels in the blood. It is critical in cardiovascular health to lower the risk of cardiac diseases.

Jellyfish are very low in calories and carbs. Jellyfish have certain properties that make them heart-healthy foods.

Maintain Normal Blood Pressure

The collagen found in jellyfish has the potential to help decrease blood pressure. Polyphenols (an antioxidant) may help prevent artery hardening.

It significantly decreases blood pressure while also promoting smooth blood circulation. As a result, it aids in the improvement of blood vessel health.

Non-culinary Applications of Jellyfish

Jellyfish can be used for more than just cooking. On the contrary, it contains a plethora of fascinating non-culinary benefits. Let us look at a couple of them.

Keeping Jellyfish as Pets

The moon jellyfish is a frequent variation among ornamental fishes. They may also be able to survive in temperatures ranging from 27 to 30 degrees Celsius. It is appropriate for warm home aquariums.

Potent Fertilizer

Desalinated and dried jellyfish chips are utilised as organic fertilisers. Jellyfish chips are used in forest restoration operations to revitalise and regenerate woodlands.

It improves the soil’s nutritional content, which inhibits weed growth. It also enhances the moisture content prior to seeding. The fertilised culture of jellyfish has consistently yielded superior results than rice bran or other organic fertilisers.

Environmentally Friendly Jellyfish

Go Jelly is an initiative that aims to minimise microplastic contamination in water bodies and save them. Due of the minimal size of microplastics, sewage treatment is currently poor in trapping them. Jellyfish mucus, on the other hand, has been shown in experiments to be effective at binding microplastic.

As a result, biofilters reinforced with mucus are being used in sewage treatment plants and factories that generate microplastic waste. It not only protects the environment, but it also aids in the control of the jellyfish population.

Artificial Tears

Mucin is a protein found in jellyfish that has the ability to retain moisture. As a result, it is employed in artificial tears. Furthermore, jellyfish use mucin to defend themselves against predators.

Space Exploration

Jellyfish were employed as experimental specimens in space research to investigate the various phases of growth in microgravity. Gravity is sensed by calcium sulphate crystals in jellyfish.

They also offered remarkable data when replicated in zero gravity space and survived in the earth’s atmosphere. Space-born jellyfish paved the way for new frontiers in scientific research and the possibility of extraterrestrial life.

Jellyfish Side Effects and Complications

Jellyfish stings are a major source of danger for swimmers, waders, and divers. The sting may include venom that is lethal. The symptoms of jellyfish stings vary based on the species of jellyfish. The following are primary symptoms:

  • Itching, rashes, and pain
  • Breathlessness
  • Chest ache
  • Lymph node enlargement
  • Cramps in the muscles
  • Cramps in the abdomen

Allergic reactions

There have been reports of anaphylactic reactions or allergies caused by jellyfish eating. Allergies cause skin blisters, numbness or tingling sensations, nausea, vomiting, and other symptoms.

Aluminum Toxicology

Anglers use a lot of aluminium to keep jellyfish alive. In addition, potassium aluminium sulphate is used as an adjuvant. However, over usage of this substance causes degenerative disorders such as Alzheimer’s, inflammatory bowel disease, and others.

Precautions to Take When Using Jellyfish

Avoid consuming fresh jelly fish in your diet.

Jellyfish decompose in a matter of hours and become toxic. As a result, it is best to consume it in dried or pickled form.

Suit of Defense

Wear a stinger or skin suit when swimming or diving in jellyfish-infested seas. It is composed of high-quality cloth to keep you safe from such dangerous stings. Protective footwear is also recommended to avoid stings at the beach or in shallow water.

Be Well-Informed

Make yourself informed of the safety precautions and environment in coastal waters that may contain jellyfish. You can get information from lifeguards, residents, or government officials.

It may provide you with a safer and more enjoyable experience when participating in aquatic activities. During the jellyfish spawning season, it is also safe to avoid both the water and the beaches.

Conclusion

Jellyfish are thought to be some of the planet’s earliest surviving. They existed before to the dinosaurs. They also adjust to changing temperatures. Some cultivars flourish in subarctic environments as well.

As a result, these gelatinous aquatic animals are gaining popularity around the world for a variety of reasons, including health benefits and research. Furthermore, due to the disappearance of their predators, jellyfish populations are exploding.

You, too, can profit from this sea creature. However, you must first be informed and use it correctly.
