Types of fish that contain a lot of mercury, remember to limit buying when going to the market
Fish is a delicious, nutritious food that many people love, however there are some types of fish that are not recommended to eat much because they contain a lot of mercury which is harmful to health.
Does eating a lot of fish cause mercury poisoning?
VnExpress quoted nutritionist Hoang Ha Linh from the Vietnam Institute of Applied Medicine as saying that fish is one of the healthiest foods, providing a source of omega-3 fatty acids, protein, micronutrients and healthy fats. However, many people are concerned that some types of fish may contain high levels of mercury, which is toxic to the body, so they limit their intake.
Mercury is a heavy metal found in air, water, and soil. People can be exposed to this toxic substance in many ways, including breathing in mercury vapor during mining and working in industrial activities. Some fish and shellfish are at risk of absorbing small concentrations of mercury in contaminated water. Many cases of mercury exposure are caused by eating these foods.
In fact, nutritionists recommend that people eat at least two servings of fish per week (about 340g). However, be careful with types that contain high levels of mercury, and choose safer types.
In general, larger and longer-lived fish tend to contain more mercury.
