Fish is a highly nutritious food, packed with protein, vitamins, and minerals that are essential for a healthy body. Compared to red meat, fish is considered a healthier option and offers numerous health benefits. Fish is versatile and can be prepared in a variety of dishes, adding variety to your family’s meals. Many experts recommend consuming fish at least twice a week to reap the wonderful benefits of this superfood. In Japan, where life expectancy is among the highest in the world, fish and other seafood are staple foods regularly featured on their tables.
While fish offers numerous benefits, there are certain individuals who should avoid consuming it due to potential negative impacts on their health.
People with Fish Allergies
Individuals with allergies to specific foods should refrain from consuming those foods, even in small quantities. This is also true for those allergic to fish. Common allergy symptoms include itching, swelling, and hives after consumption. In more severe cases, some individuals may experience difficulty breathing, and their lives could be at risk.
People with Gout
Individuals with gout should select foods with low purine levels and avoid fish, especially certain types of fish like herring and sardines, as they are high in purines, which can lead to increased uric acid levels in the blood. Consuming fish can cause joint pain and discomfort for people with gout.

People with Digestive Issues
For those with digestive problems such as a weak digestive system, ulcerative colitis, or stomach aches, it is best to limit fish consumption, especially raw fish. Raw fish may contain bacteria and parasites that can be harmful to the gut. Individuals who have recently undergone surgery or are experiencing diarrhea should also avoid eating fish to prevent further complications. When consuming fish, it is advisable to opt for cooked or boiled preparations rather than raw fish.
Individuals Taking Medication
Generally, all types of fish are rich in omega-3 fatty acids, especially marine fish. While this is an essential nutrient for the body, it can interact with certain medications such as blood pressure and blood-thinning drugs. Omega-3 can increase the risk of bleeding in individuals taking blood thinners. Additionally, those taking medication for chronic illnesses should consult their doctors before including fish in their diets.
People with Liver or Kidney Diseases
Fish, especially marine fish, tends to be high in protein and salt, making it unsuitable for individuals with liver or kidney problems, including cirrhosis or inflammation of the liver. The protein in fish can put additional strain on the liver and kidneys, affecting the treatment process and worsening the condition.
When purchasing fish, opt for fresh fish and ensure it is thoroughly cooked before consumption to avoid bacterial or parasitic infections. Cooked fish should be consumed promptly to ensure optimal flavor and nutrient retention.
If you experience any unusual symptoms after eating fish, it is advisable to stop consuming it and seek medical attention if necessary.
While fish can be a delicious and nutritious addition to your meals, it may not suit everyone. We hope this information helps you understand the considerations regarding fish consumption and enables you to make informed choices when planning your family’s meals.
