What are the drawbacks of eating too much fish skin?
Generally speaking, consuming too much fish skin may lead to several adverse effects, including increased digestive burden, higher risk of elevated blood lipids, allergic reactions, intake of harmful substances, and abdominal discomfort such as bloating. A detailed analysis is as follows:

1. Increased digestive burden: Fish skin is rich in collagen and connective tissue, which has a relatively tough texture. Excessive consumption can increase the gastrointestinal digestive load. Individuals with weak digestion are particularly prone to symptoms such as bloating, belching, and food stagnation. Long-term overconsumption may impair gastrointestinal function.
2. Increased risk of elevated blood lipids: The skin of certain fish contains high levels of fat, mostly saturated fatty acids. Overconsumption can lead to excess calorie and fat accumulation, raising blood cholesterol and triglyceride levels, which is detrimental to cardiovascular health. People who are obese or have hyperlipidemia should be especially cautious.
3. Allergic reactions: Fish skin contains various proteins that are common allergens. Excessive intake may trigger or worsen allergic symptoms, such as skin itching, rashes, and sore throat. Individuals with allergic constitutions face a higher risk.
4. Intake of harmful substances: Fish may live in polluted environments, and their skin, being an outer layer, tends to absorb heavy metals, pesticide residues, and other harmful substances. Consuming too much fish skin increases the risk of accumulating these toxins in the body, potentially harming health.
5. Abdominal bloating and discomfort: During digestion, fish skin tends to produce gas in the intestines. Overeating it can lead to increased intestinal gas, causing bloating and excessive flatulence. These effects are more pronounced when consumed on an empty stomach.
To safely enjoy fish skin, consumption should be moderate. Choose fresh fish from reliable sources, thoroughly wash and cook it well to remove surface impurities and harmful substances. Pairing fish skin with vegetables and whole grains helps balance nutrition while minimizing potential risks, supporting a healthy and balanced diet.
