Why eating fish in excess amounts could harm our Gut health?

Some people start eating too much fish. But it is said that in excess of amrita is like poison, eating anything in excess is harmful to health. Similarly, consuming too much fish can lead to several side effects.

Fish is one of the healthiest and most delicious foods on the planet. It is packed with protein, omega-3 fatty acids, and other essential nutrients. Unfortunately, too much of a good thing can be bad for your gut health. Here are 7 reasons why eating too much fish can affect your gut health.

High Levels of Mercury

Many types of fish contain high levels of mercury, which can cause digestive issues like nausea, vomiting, and abdominal pain. In addition, mercury can damage your gut bacteria and reduce their ability to digest food properly. Therefore, it is important to consume fish in moderation and to avoid eating fish that contain high levels of mercury.

Too Much Salt

Fish can be high in sodium, which can contribute to an imbalance in the gut and cause digestive issues like bloating and constipation. To reduce your risk of these issues, it is important to choose fish that is low in sodium or to limit the amount of salt you add during cooking.

Lack of Fibre

Fish does not contain any significant amounts of fibre. This lack of fibre can lead to an increase in bad gut bacteria and an imbalance in your gut microbiome. To ensure a healthy gut, it is important to consume a variety of foods that are high in fibre, such as vegetables, fruits, and whole grains.

Unhealthy Fats

Some types of fish contain unhealthy fats such as trans fats and saturated fats. These fats can increase inflammation in the gut and lead to digestive problems such as irritable bowel syndrome (IBS). Therefore, it is best to opt for leaner types of fish that are low in unhealthy fats.

Too Many Antibiotics

Farmed fish are often given antibiotics to prevent disease and promote growth. This can lead to an overgrowth of bad bacteria in the gut and an increased risk of gastrointestinal infections and other digestive problems. Therefore, it is important to opt for wild-caught or sustainably farmed fish whenever possible.

Environmental Contaminants

Fish are exposed to environmental contaminants such as heavy metals, pesticides, and microplastics from polluted water sources. These contaminants can damage your gut bacteria, leading to digestive problems like bloating, nausea, and fatigue. Therefore, it is important to purchase fish from safe sources and ensure that they are properly cooked before consuming them.


Some people may have a fish allergy or intolerance that can cause digestive symptoms such as abdominal cramps, diarrhoea, and vomiting after consuming fish products. If you experience any adverse reactions after eating fish, it is important to speak with your doctor about potential allergies or intolerances that you may have.
