Pork liver

Pork liver is the detoxification organ of pigs and is believed to contain a large amount of toxins and heavy metals. In fact, the animal's liver and kidneys help metabolize heavy metals and other harmful components, but this does not mean that they will store these substances .

In addition, China has limit requirements on harmful ingredients in fresh food. As long as the animal offal products are purchased through formal channels, they have been quarantined and can be eaten with confidence .

Pork liver is rich in iron , which is very effective in preventing anemia. At the same time, pork liver is also rich in vitamin A , which helps protect eyesight and maintain skin health.

As long as you choose pork liver from a reliable source and eat it in moderation, you can take advantage of its nutritional benefits.

Duck Blood

Duck blood is considered to be the garbage toxins in animal blood vessels. In fact, there is no garbage or toxins in animal blood vessels, only the metabolic products of cells.

These metabolites are transported by the blood to the liver and kidneys, where they are filtered or converted into other substances, which means that generally no metabolites remain in the blood .

In addition, animal blood used for food must come from animal blood that has passed quarantine; in addition, it will also undergo sterilization and other processing during the production process, and will be subject to random inspections by supervisory departments after it is put on the market.

In fact, duck blood is rich in high-quality protein, a variety of trace elements and minerals, especially iron, which has a good effect on blood supplement **. **

As long as you make sure you buy duck blood from a reliable supplier, you can consume it with confidence, but be careful to consume it in moderation.

Fish head, fish skin

Fish heads and fish skin are the parts of fish that accumulate more mercury. Is eating fish heads and fish skin equivalent to eating "poison"? In fact, the methylmercury limit standard in my country's aquatic animals and their products (except carnivorous fish and their products) is 0.5 mg/kg, the methylmercury limit standard in carnivorous fish and their products (except products of tuna, golden eye sea bream, marlin and above) is 1.0 mg/kg, and the methylmercury limit standard in tuna and its products is 1.2 mg/kg.

Generally speaking, the mercury content in fish we purchase through regular channels is in line with national standards.

Fish skin is also a nutritious food. It is rich in collagen, which helps to keep the skin elastic and moisturized. Fish heads are actually a treasure trove of nutrients. Fish heads are rich in high-quality protein, vitamins and minerals, especially DHA and EPA, which are beneficial to brain development.

Fish gall contains a large amount of bile salts, toxins and histamine. Accidental ingestion may cause kidney failure or liver disease, and in severe cases may even be life-threatening. Do not eat it!
