護理師正在教導病人健康的飲食習慣。下列哪種食物選擇最能代表瘦肉蛋白的來源？

瘦肉蛋白（Lean protein）在健康的飲食中扮演重要角色，主要提供必需胺基酸且脂肪含量較低，有助於肌肉修復與代謝平衡。鮭魚不僅是優質的瘦肉蛋白，更富含 Omega-3 不飽和脂肪酸，對心血管健康有益。相比之下，炸雞翅含過多油脂與反式脂肪，培根與香腸則屬於高飽和脂肪與高鈉的加工肉品，長期食用不利健康。

Lean protein plays an important role in a healthy diet, providing essential amino acids while remaining low in fat, which supports muscle repair and metabolic balance. Salmon is not only a high-quality lean protein but is also rich in omega-3 unsaturated fatty acids, which benefit cardiovascular health. In contrast, fried chicken wings contain excessive oil and trans fats, and bacon and sausage are processed meats high in saturated fat and sodium, all of which are unhealthy for long-term consumption.
