7 Worst Foods For Your Brain


7. Fish High in Mercury

Research reveals that mercury is a heavy metal contaminant that is capable of being store within animal tissues for long periods of time, and it acts as a neurological poison to the brain. Predatory fish that has had a long lifespan tends to be particularly likely to boost a rich build-up of mercury, and it can even carry more than 1 million times richer concentration of mercury than the water it is surrounded with.

Therefore, seafood, especially wild fish varieties, are the basic food source that adds mercury to the human diet. When an individual ingests mercury laden fish, it tends to spread throughout the body, and gets concentrated within the brain, the kidneys and the liver. When pregnant women ingest mercury, it tends to concentrate within the placenta and foetus.

Mercury toxicity can cause some extremely damaging effects to the brain, for instance it can disrupt the entire central nervous system, the function of neurotransmitters, and the stimulating of the neurotoxins, which can severe disruption in the brain. When a young child or a developing foetus is exposed to mercury, it causes serious disruptions to brain development, along with destruction of vital cell components. This has been found as the leading cause of cerebral palsy, and several other delays in developments along with brain deficits.

Why is there Mercury in Fish

However, keep in mind that most fish varieties don’t pack up large doses of mercury and you shouldn’t eliminate them from your diet for they contain countless powerful nutrient, including omega-3 fatty acids, iron, magnesium, vitamin B12, zinc and high quality protein. Experts recommend adults to consume at least three servings of fish each week, however, if you’re consuming swordfish or shark, be sure to limit yourself to one serving a week.

It is essential for children and pregnant women to avoid consuming fish that contains high doses of mercury, these include orange roughy, tilefish, swordfish, tuna, shark and king mackerel. It is safe to consume two to three servings of fish with low concentrations of mercury each week.

The recommendations given by experts on this matter tend to vary based on the various countries and regions, depending on the kind of fish varieties you find in your area. Therefore, it is highly advisable to consult your local food safety agency to receive most accurate recommendations. Moreover, if you enjoy fishing, be sure to consult your local authorities regarding the levels of mercury present within the waters where you chose to fish.

Simply put, mercury is an extremely harmful neurotoxic compound that is particularly damaging for children and pregnant women, and it is largely found within large predatory fish varieties, such as swordfish and shark.

The bottom line is that our daily diet and the foods we chose to eat tend to have a huge effect on the health and functioning of our brain. Consuming an unhealthy and highly inflammatory diet, which revolves around excessive sugar intake, refined carbs, processed treats, fried foods and unhealthy fats, leads to brain damage, memory loss, learning impairments and cognitive disturbances, along with increasing the risk factors of ailments such as dementia and Alzheimer’s.

Food items contain several harmful substances that can prove to be dangerous for our brain. Alcohol has been found the main culprit that causes excessive brain damage when consumed excessively, while certain seafood varieties are loaded with mercury, which makes them neurotoxic and capable of causing permanent damage to the brain, particularly the developing brains of children and foetus.

However, this by no means indicates that you must eliminate these food items from your daily diet entirely, because even fish and alcohol pack up a wide variety of nutrients and health benefits. Therefore, it is important to practice mindful moderation and create a rich diet that is loaded with nutrient-rich whole foods and fresh produce.
