Many of us eat fish as they are healthy and delicious. Fishes have proteins, omega 3 fatty acids plus several other nutrients and these would be superb for the health. Maintaining good gut health is very essential for us. If the gut heath is good then our heart health, immunity levels plus brain health, sleep etc would also be good. We must be careful and not consume fish in huge quantities or in excess quantities as they could harm our health.
Reasons why eating excess fishes could harm our gut health
High levels of mercury:
It is true that many types of fishes contain high levels of mercury in them and would lead to issues like abdominal pain, nausea, vomiting etc in us. The gut bacteria would get damaged and the ability to digest food would be lowered also.
Too much salt:
By eating an excess amount of fish, we could get an imbalance in the gut due to the high sodium content present in the fish. There are chances that we could get digestive issues like bloating and constipation etc . Therefore, we must select those fishes that are low in sodium content.
Lack of fibre:
The bad gut bacteria would become more when we eat fishes that do not have any fibre content. By this, we could have an imbalance in our microbiome. For the gut health to be good, we must eat foods like whole grains, fruits, vegetables etc.
The inflammation of the gut would be increased by eating certain fishes rich in unhealthy fats. Unhealthy fats refers to trans fats and saturated fats etc. There are possibilities of getting issues like IBS also. Point is that it is good to eat fish that are low in unhealthy fats.
Increased risk of GI infections:
To prevent disease and promote growth, farmed fish are given lots of antibiotics. There would be overgrowth of bad bacteria in the gut by eating farmed fishes. GI infections would increase also.
There are some people who get issues like abdominal pain, diarrhoea, vomiting etc after eating fish. This could be due to fish allergy.
