Eating fish on an empty stomach can lead to gout attacks. Gout is a disease that causes tissue damage due to a disorder of purine metabolism leading to increased uric acid in the blood.
Some types of fish are very rich in purines - over 150 mg/100 grams such as sardines, anchovies, whitetail... If you consume a large amount of fish containing purines on an empty stomach without enough carbohydrates to break them down, the body's acid-base balance will be unbalanced, easily causing gout or increasing uric acid levels in the blood.
You should not eat fried fish. You should prepare food by steaming or boiling. Eat fish in moderation and consume safe, moderate amounts of food as prescribed by nutritionists to avoid uric acid accumulation and flare-ups of pain.
Fish is a nutritious, delicious food that is very good for the brain and body. However, for people with high uric acid, there are taboos when eating fish and cannot be combined with other foods without the advice of a medical professional.
