Many people like to eat chicken heads, duck heads, goose heads and fish heads. Indeed, the heads of these fish and poultry are very tasty and their nutritional value is also high. However, these "heads" are also harmful. Take chickens, folks said: Ten years of chicken head game arsenic. This means that the older the chicken, the greater the toxicity of the chicken's head. From a modern medical point of view, the reason is that chickens will eat substances that contain harmful heavy metals during foraging. These heavy metals are mainly stored in brain tissue. The longer the chicken age, the greater the storage capacity and the stronger the toxicity. While enjoying the delicious taste of chicken, consumers also consume heavy metal poisons. If they eat too much, they may cause poisoning. Therefore, the chicken head should not eat more. Duck heads, goose heads, etc. should not eat too much, the reason is very much the same.
What about the fish head? Due to the deterioration of the overall environment in recent years, water pollution has increased, and harmful substances have invaded into fish. Together with fish, especially carnivorous or omnivorous fish, at the top of the food chain in the water, these harmful chemicals are also the most accumulated in the body. This phenomenon is medically known as enrichment. In addition, some unscrupulous farmers and traders add chemical substances to the feed, which further aggravates the accumulation of harmful substances in the fish. These substances mainly accumulate in fish heads that are relatively concentrated in fish oil. Therefore, it is better to advise those who like to eat “heads†to get rid of this hobby.
