I am blessing pa, clinical nutrition division, hope my answer is useful to you.
The airing of piscine fim classics that fim is large cartilage fish is made after dehydration, the majority is the piscine fim of the shark. Be in from of old, fim is among the dietary culture that is in China one kind advanced feed capable person, be not wealthy person and VIPs to cannot be enjoyed. Fish industry developeded now, the price of fim also falls somewhat, but the course that remains the ability on high-grade banquet to be able to appear is tasted.
People thinks fim is OK and nourishing the body, defer consenescence, enhance immune power, can fight tumor even. Also be, without so much effect, how can Where is the price of fim of not let sb down?
However, analyse the nutrient composition of fim to be able to discover from the angle of contemporary dietetics, the nutrient value of fim and its price is complete unworthily. Main ingredient is protein among fim, among the fim after bubble is sent, protein takes an in part almost, and adipose less. But but what must not think fim is compensatory protein is admirable feed capable person. The protein of fim 80% above are collagen albumen, and it is macromolecule collagen albumen, the collagen albumen that tastes with a few high-grade health care is different. The collagen albumen that health care tastes is the albumen of young member collagen of hydrolysis, specific absorption is higher, and the collagen albumen of fim cannot be absorbed to use directly by human body, can be digested to decompose amino acid by gastric bowel path however, after absorbing, ability is used. Collagen albumen itself is a kind of inferior albumen, the lubricious ammonia with devoid indispensible human body is acerbity (a kind of indispensible and amino acid) , pleasant ammonia is acerbity (a kind of blame must amino acid) occupy 30% above however. So the mankind uses capacity to the absorption of collagen albumen is it is very poor.
Still having a kind of conduct propaganda is to say fim contains shark cartilage element, and shark cartilage element has fight tumor, fight consenescence, defer knee joint decay to wait sanitarian function a moment. Shark cartilage element is contained really among fim, but content is not high, true shark cartilage element is extracted in the cartilage crusty pancake of the shark. The effect of itself of shark cartilage element also is worth to hit very much greatly interrogation. Say shark cartilage element is not high temperature resistant again, course cooking can have many loss. Shark cartilage element is not acid-proof still, eat to fall to also can lose active in the action of hydrochloric acid in gastric juice in the stomach.
Fim not only nutrient value is officinal value is finite, still have a fatal flaw, it is heavy metal exceeds bid. The shark is marine and top class prey animal, pollute badly in ocean environment today, the strong market that the shark is heavy metal implement. Via detecting of the heavy metal such as fim mercuric cadmium exceeding bid is common phenomenon.
Fim nutrition value, officinal value is not high, but the nourishing god in waiting for fokelore with horn of tiger bone, rhinoceros implement same, caused the disaster of the shark. Encircle the demand to fim to supply a Chinese, count ten million shark every year to take fim at cutting to death, bring about marine ecological balance to be destroyed.
Without buying and selling, do not have kill! Do not eat fim please!
