Can seafood and coconut be eaten together?
Generally, seafood and coconut should not be consumed together. The analysis is as follows:

Seafood is rich in protein, purines, and sodium ions, while coconut contains high concentrations of potassium, magnesium, and natural sugars. Consuming them together may lead to health risks due to electrolyte imbalance. Purines in seafood metabolize into uric acid, and the high potassium content in coconut water might interfere with the kidneys' excretion of uric acid. This is particularly concerning for individuals with gout or kidney insufficiency, as it may trigger joint pain or abnormal blood potassium levels. Additionally, the cooling nature of coconut combined with the cold properties of seafood may irritate the gastrointestinal tract, causing diarrhea and abdominal pain. For those with weak spleen and stomach function, gastrointestinal spasms or indigestion may easily occur.
Fructose in coconut may interact with protein in seafood, affecting the efficiency of nutrient absorption. Fructose must be metabolized by the liver, and excessive intake may inhibit the liver's ability to break down proteins. If high-quality proteins from seafood are not promptly broken down by digestive enzymes, they may lead to bloating and belching. Moreover, phytochemicals in coconut might bind with heavy metals in seafood, increasing their bioavailability. Long-term consumption of both together may heighten the risk of heavy metal accumulation in the body.
If you wish to enjoy both foods, it is advisable to consume them at different times to minimize potential adverse effects on the body. Individuals with weaker constitutions or specific medical conditions, such as diabetes or hypertension, should be particularly cautious when consuming coconut and seafood to avoid exacerbating their conditions.
