The statement that "Eating Fish Is Really Bad for You" is a highly misleading statement written by a source that is very bias when it comes to the consumption of any animal. Despite the source being highly misleading, there is some truth to it though not in the way it described as. The reason as to why there is a large group of people that talk about how bad fish is for you is because of the higher mercury content that they contain; though the main characteristic is that you have to understand it only starts to become unhealthy when you eat an excessive amount.
the FDA and EPA recommend that we consume around 8 ounces of fish per week in order to sustain a well nutritional diet. The reason as to why we need to consume some number of fish is that they a lean animal protein and have omega-3 fatty acids. Many nutrients that fishes contain are those that may treat and or prevent the following: Heart attacks and strokes, boost brain health, treat depression, risk of autoimmune diseases, preventing asthma in children, protecting vision in old age, and improve sleep.
The reason as to why there are so many connotations to eating fish is because when you consume more than what's recommended, the higher levels of mercury can cause stress on a body. It affects pregnant woman by having too much mercury affect the brain development of the child; for children it can impair motor skills, cause problems thinking, issues with hand eye coordination. For adults it doesn't exclude muscle weakness, metallic taste in the mouth, nausea and vomiting, lack of motor skills, change in vision or hearing.
Yet compared to the article saying that "fish is really bad for you" it failed to mention the benefits and negatives of over consumption of fish. Not bringing up the fact that Mercury poising is bad, alongside the failure to mention the many benefits that including fish in your diet may have.
