Yes, salmon skin is safe to eat and is actually quite nutritious for you. The skin of salmon is a good source of omega-3 fatty acids, protein, and other nutrients. However, it's important to make sure that the skin is cooked properly, as undercooked salmon skin can be tough and chewy. If you're cooking salmon with the skin on, make sure to cook it until it is crispy and golden brown, which should take around 3-4 minutes per side over medium-high heat. This will help to ensure that the skin is both safe to eat and enjoyable in texture.
