When it comes to eating fish, we Chinese too good at it! In addition to fish meat, from fish heads and skins to roe and tails, there are delicious ways to eat them.
For example, the famous dish of "chopped pepper fish head" is widely popular with the public. Whether it is daily consumption, or new year's festivals, auspicious celebrations, it is indispensable on the table.
Of course, some claims about fish heads are also circulating among the public. The most famous of these are the two sayings that "fish heads can replenish the brain" and "fish heads contain a lot of toxins and heavy metals, and cannot be eaten".
Today Xiaobian will talk about fish heads and solve puzzles for everyone
Can a fish head replenish the brain?
From the perspective of nutrition, there is a certain truth in eating fish heads to supplement the brain.
First, the fish head contains lecithin, which is found in the meat of the fish.
After lecithin is metabolized by the human body, it can be decomposed into choline, which in turn can be synthesized into acetylcholine. Acetylcholine is one of the most important "neurotransmitters" that has the effect of enhancing memory.
Secondly, fish heads contain two essential unsaturated fatty acids: docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA).
These two substances are commonly known as "brain gold", and proper intake helps the development of the baby's brain, the maintenance of brain function, the improvement of brain function, the improvement of thinking ability, and the auxiliary treatment of Alzheimer's disease.
At the same time, they have certain benefits for softening blood vessels, reducing blood lipids, and delaying aging.
Finally, fish heads also contain more calcium and phosphorus than other meats, which helps with bone and brain development.
However, it should be noted that eating fish heads can supplement the brain, but this does not mean that it can improve the IQ of adults.
Also, the cholesterol content in fish heads is high, and the amount of consumption should be controlled.
Fish head contains a lot of toxins, heavy metals, can not eat?
Under normal circumstances, it is safe to eat fish heads.
Because fish excrete toxins through gills and organs such as liver and kidneys, it is not related to fish heads.
However, if the waters and ecological food chains where fish live are contaminated, or if bad breeders illegally add certain chemicals to fish feed, it may increase harmful substances in fish to some extent, such as pesticides, pathogenic microorganisms and heavy metals such as mercury, cadmium, chromium, lead, arsenic and so on.
At this time, the entire fish, including the head of the fish, is contaminated, and toxins accumulate in the fish for a long time, which is difficult to discharge, and is indeed not suitable for human consumption.
In particular, fish heads contaminated with heavy metals such as mercury, cadmium, and lead can endanger human health after consumption.
The eaters are slightly nausea and vomiting, dizziness and headache, loss of appetite, general weakness, and heavy digestion, nerves, immunity, reproduction and other systems are damaged, and even carcinogenic, such as liver cancer, kidney cancer, breast cancer and skin cancer.
It can be seen that whether the fish head is poisonous or not mainly depends on whether its growth environment is safe. Therefore, when buying and making fish, it is generally recommended to:
(1) Purchasing from a formal market that is supervised by government departments can ensure food safety to the greatest extent.
(2) Try to choose smaller fish.
Because the larger the fish, either at the high end of the biological chain, or the older the fish, the more harmful substances (such as lead, cadmium, mercury, etc.) stored in the body, the greater the impact on the human body.
(3) When cooking fish heads, be sure to cook them thoroughly.
After these two problems are solved, let's talk about the gold collocation of fish heads
