Consuming fish skin provides health benefits
Is it true that consuming fish skin provides health benefits?
Partly. Consuming fish skin and utilizing its extracts yields various health benefits, primarily driven by bioactive collagen peptides and hydrolysates that exhibit antioxidant, anti-inflammatory, and wound-healing properties.
Verdict: OVERSTATED · 5 sources for, 0 against · Last checked
The retrieved literature consistently supports the claim that fish skin and its derived components (such as collagen peptides and gelatin) offer health benefits, including antioxidant, anti-inflammatory, and wound-healing properties. The papers specifically investigating fish skin or fish by-products (e.g., [1], [4], [5], [7], [10]) all point to positive health outcomes. Therefore, the claim is well supported.
Fish skin and its extracted collagen peptides and hydrolysates exhibit antioxidant, anti-inflammatory, and wound-healing properties in laboratory and nutritional studies.
