1, fish scales
Fish scale is the exoskeleton of fish, which contains a lot of lecithin and collagen, and minerals such as calcium and phosphorus are also very rich. In this way, protein can only be converted into gelatin at a temperature above 70℃.

Fish sausage contains high-quality protein with low fat content and high medicinal value. But before that, the fish pond must be thoroughly cleaned, because some food eaten by fish must be digested by fish intestines and easily polluted.
3. Fish liver
Dried fish is very nutritious and contains a lot of vitamin D, iron and vitamin A, but it is beautiful and high in cholesterol, so it is not suitable for gout patients. Fish gall and fish liver are directly connected. Never break the fish gall directly when cleaning. The liver itself has a certain detoxification function, and it is easy to accumulate a large number of toxins. Before eating, make sure that the fish is not polluted by the environment.

The swim bladder contains a lot of omega-3 unsaturated fatty acids and collagen, which can control blood lipids. Just wash the swim bladder thoroughly and stew it together.
5. Fishbone
If the fishbone contains a lot of calcium, the nutritional value contained in it can be quickly digested and absorbed by the human body after softening. For smaller fishbones, you need to chew hard, which can make the fishbones soften as soon as they enter the stomach and promote the dissolution of phosphorus and calcium. Fish bone absorbs fish bone marrow, and vinegar can promote fish bone softening.
