Welcome to our video on 10 more fish you should never eat our last video on Seven Fish you should never eat was a hit and we had many comments and questions about additional fish so we expanded our research and compiled a bigger picture of the fish that can potentially cause major health problems as well as healthier options to help you make better choices when it comes to Seafood consumption to understand what fish is helping and what fish may actually be damaging your body okay let's recap our first video the original seven fish that you should never eat included tilapia king mackerel orange roughy swordfish shark tilefish and eel broadly these tend to contain high levels of toxins such as mercury pcbs and other heavy metals which can be extremely harmful to human health it's a serious concern because these contaminants can lead to neurological problems increased heart disease risk and more okay so that's the original Seven to avoid now let's move on to our expanded list of 10 more including other popular fish that contain heavy metals some dodgy farming practices to be aware of mislabeling and other considerations as well as a complete list of super healthy fish that are less likely to be contaminated but first can you do us a favor click on the thumbs up and help us spread the word about heart disease prevention and ring the bell to stay up to date with our latest videos we want to make sure you get the latest info so you can live a long healthy life and stick around to find out how to get two heart-healthy free gifts we guarantee both you and your heart will love them okay let's get into it number 10 Marlin The Majestic Marlin is admired for its beauty and prowess however this one is better left in the ocean Marlin are known to accumulate high levels of mercury due to their position at the top of the food chain Mercury is a toxic heavy metal present in the oceans due to both natural and human activities fish accumulate Mercury over the years particularly fish that live longer or are at the top of the food chain when we consume fish we're often getting small amounts of mercury which can pose major health risks including neurological damage cognitive impairment vision loss hearing loss kidney dysfunction and cardiovascular disease that's why it's important to choose low mercury fish and consume it in moderation but because Marlin eats smaller fish and have no natural Predators they accumulate a lot of mercury over time and while everyone should avoid Marlin it's particularly important for pregnant women Studies have found high levels of mercury in breast milk showing that this toxin is passed on through breast milk where it can have a magnified effect on early development according to a panel at the Harvard Centered for risk analysis parental exposure to methyl mercury has been associated with a decrease in IQ while other studies found deficits in neurobehavioral test scores in children so it's best to stay away from Marlin it's a high Mercury fish which is linked to severe health issues and there are simply better options to choose from which we'll cover later on number nine tropical reef and warm water fish water poisoning is a big problem in tropical and subtropical regions including the Caribbean Pacific Islands the Indian Ocean and the Gulf of Mexico it's something you want to avoid at all costs as the consequences can be dire cigwatara poisoning comes from fish contaminated with sigua toxins these are naturally occurring toxins produced by microscopic algae found in Coral Reef ecosystems siguotoxins accumulate in various species of predatory reef fish including grouper Barracuda sturgeon sea bass red snapper amberjack parrotfish and Triggerfish now some of these Fish can be found in different parts of the world what we're really concerned about here are the ones grown in warm water and around reefs which are particularly vulnerable to cigwatara poisoning symptoms of siguator poisoning can be diverse ranging from nausea vomiting and diarrhea to headaches dizziness and muscle aches in severe cases people experiencing difficulty breathing irregular heartbeat and even temporary paralysis recovery can take anywhere from a few days to several months or years and some people suffer with long-term recurring symptoms unfortunately cooking doesn't destroy this Toxin and worst still saguatara poisoning appears to be increasing due to warming oceans which contributes to the proliferation of the toxic algae prevention is key with this one so if you're vacationing on a tropical island or anywhere with warm water it may be best to avoid consuming large predatory reef fish search for news updates in the area or ask a local if there are currently any cigarthura outbreaks finally avoid eating internal organs as that's where toxins accumulate the most number eight farmed shrimp shrimp is one of the most popular seafood choices worldwide and in the U. S it's estimated to make up 25 of seafood consumed as the demands for shrimp has skyrocketed so has the intensity of farming practices this is where the problems arise with more shrimp being grown in less space disease and contamination have become significant issues to combat these problems Farmers often resort to using chemicals and antibiotics as a result farmed shrimp present a particularly concerning problem when it comes to antibiotic resistance a 2015 study published in the journal biomed research international found that 75 of the bacteria strains in farmed shrimp samples showed antibiotic resistance this is alarming as antibiotic resistance leads to more difficult to treat infections and illnesses in humans to make matters worse one of the challenges with shrimp is the difficulty in tracing the origins of shrimp sold in the market shrimp is often mislabeled or has no information at all making it hard for consumers to know the truth about where their shrimp comes from and under what conditions it was produced according to a 2014 investigation by the Oceania group 30 of the shrimp samples they tested in the US were mislabeled making it impossible for consumers to know exactly where they're buying so be cautious about farmed shrimp look for a supplier you can trust who shows transparency and traceability along the supply chain don't be afraid to ask questions your health may just depend on it number seven Spanish mackerel Spanish mackerel a popular and delicious fish has become a staple in many Seafood lovers diets and while the Spanish variety contains less Mercury than its cousin the king mackerel caution should be exercised as we discussed mercury poisoning increases your risk for cardiovascular disease kidney damage problems with focus and brain health and more in addition to Mercury Spanish mackerel is often contaminated with polychlorinated biphenyls or pcbs industrial chemicals that were banned in the 1970s but still persist in the environment pcbs accumulate in the fatty tissues of Spanish mackerel and have been linked to various health issues including cancer and reproductive problems now some species of fish are more susceptible to contamination but there's another major factor we need to discuss location the location where your fish is produced can have a significant impact on the levels of contamination a particularly interesting 2006 study looked at the mercury levels of Spanish mackerel caught along the Atlantic coast of the Southeastern USA compared to the Gulf of Mexico the analysis found significant differences between the two groups specifically mercury levels in Spanish mackerel from the Atlantic coast ranged from 0. 04 to 1.
3 parts per million PPM in contrast Spanish mackerel from the Gulf of Mexico was significantly higher ranging from 0. 09 to 3.
