“Four legs are not as good as two, and two are not as good as none.” Fish is rich in nutrients, low in fat, and contains nutrients such as unsaturated fatty acids, vitamin D, and selenium. However, there are 4 parts of a fish that should not be eaten!
1. Fish Head
There is a common saying that "eating fish heads can nourish the brain." In reality, fish heads are more prone to accumulating heavy metals and should not be consumed long-term.
2. Fish Gallbladder
The myth that eating fish gallbladders can cure diseases has been circulating for a long time. In recent years, cases of poisoning from eating fish gallbladders have become more frequent. In fact, many fish gallbladders are toxic, such as those in gallbladder-toxic fish. Common gallbladder-toxic fish include grass carp, common carp, mud carp, and crucian carp. When cleaning the fish's internal organs, be sure to remove the gallbladder. If it is accidentally broken, it must be thoroughly cleaned, and be careful not to get the juice in your eyes.
3. Fish Skin
Fish skin has a smooth and slippery texture, and many people enjoy eating it. However, fish skin is easily contaminated by heavy metals. Experiments show that as a fish ages, the accumulation of mercury in its skin significantly increases. In a 400-gram crucian carp, the mercury content in its skin is five times higher than in one weighing less than 200 grams.
4. Fish Scales
It is said that fish scales contain collagen, which can be used for beauty and skincare. However, the collagen content in fish scales is not even as high as that in pigskin. Moreover, collagen is not a high-quality protein and cannot be directly absorbed and utilized by the human body, let alone have any effect on beauty and skincare.
