Doctors often recommend having fish as a part of a healthy diet. Does this mean eating fish heads is safe? Read on to find out.
Can You Eat Fish Head?
Though many people in the U.S. and Europe don’t like eating fish heads because they’re too unappealing, you can eat fish heads, including the gills. Fish is rich in vitamins and calcium and is a great source of minerals.
It contains omega-3 fatty acids, magnesium, and phosphorous. I generally choose fish head when looking for a healthy meal myself, as I find it the tastiest part of the fish. Grill it with some seasoning, and you’re in for a treat.
Are Fish Gills Poisonous?
Yes and no. It depends on the species and location you’re going for. Fish gills can be contaminated with toxic chemicals and can cause a variety of infections and reactions. But this doesn’t mean all fish gills should be avoided.
They are beneficial for maintaining pH levels, are high in protein, and help with hormone imbalance. However, it is suggested that fish species be checked for areas where they are safe to consume and cleaned before using them.
Side Effects of Eating Fish Head & Gills: 4 Major Risks
While used in multiple cuisines and for medicinal benefits, the fish head might not be the best to eat. Here’s why:
Methyl Mercury
A natural, toxic mercury component, methylmercury, is particularly accumulated in fish during their life cycle. First consumed by algae, it transfers from smaller fish to larger fish, polluting all marine species.
The presence of this contaminant in humans can cause hearing and vision impairment, cerebral palsy, permanent damage to the brain and spinal cord, and some may experience memory loss.
Polychlorinated Biphenyls (PCBs)
PCBs are man-made industrial chemicals that manufacture carbonless copy papers, fluids, and cutting oils. Due to their severe carcinogenic effects, the United States Environmental Protection Agency (EPA) has banned their manufacture in the U.S. since 1979.
Studies suggest PCBs are highly cancerous, affect fetus development, cause thyroid disease, and can weaken the immune system.
Pesticides
DDT, DDE, and DDD are three long lived chlorinated chemicals present in pesticides. They are stored in most animals’ internal organs and skins, with higher trace levels in fish.
Consuming fish with even small amounts of DDT can damage the liver, reproductive functions, and nervous system and lead to tumors.
Allergic Reactions
It is possible to get allergic reactions after eating gills. The symptoms usually include nausea, vomiting, skin rash, cramps, and indigestion.
Is Fish Head Good For The Brain?
Fish heads contain important nutrients and vitamins, such as vitamin A, which is beneficial for brain development. Including fish in your diet also improves vision and immunity, making it a superfood.
In fact, consuming fresh fish reduces stress, as vitamin A fights free radicals, promoting an active mind and body.
Health Benefits of Eating Fish
Whether you like fish or not, these amazing nutritional benefits are a must read for health-conscious people.

Omega 3 fatty acids and DHA reduces anxiety and depression
Promotes physical and mental growth in infants and newborns
Prevents dementia and memory loss
Is it Safe To Consume Fish Daily?
Eating fish every day is unsafe due to increased pollution and environmental risks. According to the Dietary Guidelines for Americans, general recommendations on having fish are:
Adults can consume between 8-10 ounces of fish per week.
Children or pregnant women should have around 8- 12 ounces of fish or seafood per week.
How To Avoid Mercury Consumption From Fish
When enjoying your favorite fish, you might worry about the contaminants that can be an addition with the nutrients without you knowing. Here are some measures to consider before putting the fish on your plate:
Ensure the fish is clean and caught from a toxin-free place
Limit your weekly intake
Taking fish with lower mercury levels, such as pollock, salmon, or freshwater trout, in particular, can reduce the chances of mercury in food
Wrapping Up
Coming from a Californian background, I absolutely love seafood. One thing we do is not to ignore the fish heads and gills entirely because of their nutritional benefits. However, due to the higher level of mercury and other toxins, limiting fish intake and enjoying other seafood is important.
