In the early years, advertisements and articles about fish oil, cod liver oil, and shark liver oil flooded the Internet.
Every ad window that pops up will have cod liver oil.
However, despite such a large-scale publicity, the market has not yet analyzed and compared the composition of the three oils.
In fact, fish oil, cod liver oil and shark liver oil are three completely different things.
The main functions and ingredients of most fish oil preparations on the market are various unsaturated fatty acids. Fish oil with a relatively high EPA content has unique effects in regulating blood lipids and is suitable for middle-aged and elderly people.
Fish oil with a relatively high DHA content is a new generation of fish oil. It can improve brain health and eyesight. It is very suitable for children who overuse their brains and eyes and for those who do mental work. When purchasing, you can pay attention to the ratio of EPA and DHA in the product based on the age and specific circumstances of the user.
In general, the main components of cod liver oil include substances such as VA and VD. VD promotes rickets and bone calcification; VA promotes growth and development, maintains epithelial tissue and normal physiology. People who are suitable for cod liver oil are mostly children who do not have enough intake of these two nutrients.
Shark liver oil is amazing.
The main active ingredients of shark liver oil are squalene and glycerol.
Scientists have proven through clinical practice that squalene can directly oxygenate human cells without going through the respiratory system, fundamentally restoring the body's normal metabolism, thereby repairing damaged tissues and organs and regulating the body's health.
In addition, shark liver oil can increase the number of white blood cells and lymphocytes, so it can improve the activity of the immune system and enhance the body's resistance.
At the same time, shark liver oil is also an antioxidant that can remove environmental toxins that enter the human body and free radicals produced by the body's metabolism, thus playing an anti-aging role.
However, the shark liver oil currently on the market is generally counterfeit and inferior. If you really want to buy it, you must make sure that it has an approval number from the national administrative department, has the label of health food on the packaging, and is a product of a brand company with a good reputation, so that you can buy and eat it with confidence.
Xiang Yang looked around the store and asked, "Are there any finished products? Let me take a look first."
"Of course we have it." The shop owner enthusiastically took Xiang Yang to a row of shelves and said, "Look, this is turbot liver oil."
"What kind of fish is turbot?" Xiang Yang asked.
"Turbot is a general term for many kinds of fish, and the most common turbot is one of them." The shop owner said enthusiastically, "Turbot has a high content of gelatin, tastes delicious, and is rich in nutrition. It has a good effect of moisturizing the skin and beautifying the skin, and can nourish the kidneys and strengthen the brain, boost yang and refresh the mind. Regular consumption of turbot liver oil can nourish the body and improve people's resistance to various diseases."
Xiang Yang nodded, he understood.
Dog-skin plaster can cure all diseases.
Cod liver oil was very popular in the past, and at one point it even surpassed bird's nest.
However, since CCTV exposed in 2014 that cod liver oil is a medicine and is not suitable for long-term use, and any online advice on the use of cod liver oil cannot replace medical advice, cod liver oil is not as popular as before. Only sturgeon liver oil, shark liver oil and fish oil are still circulated in the market in large quantities.
Among them, Xiang Yang's favorite is naturally sturgeon liver oil. Sturgeons live in cold deep waters and are blessed with rich nutrients that cannot be matched by other environments. It has the effects of both fish oil and cod liver oil.
However, sturgeon liver oil is relatively expensive and is even called liquid gold in Northern Europe.
Silver cod and shark are both deep-sea fish, and their cod liver oil is very effective.
However, sharks are carnivorous fish with a very diverse diet, and there are occasional reports of contamination in shark liver oil.
Sturgeon liver oil is different. Cod is not omnivorous, clean and pollution-free. The quality of its cod liver oil is safe and reliable, and it is suitable for consumption by almost everyone.
Xiang Yang asked the shop owner, "How much is your sturgeon liver oil per pound?"
"Oh, sturgeon liver oil." The shop owner praised: "Boss, you really know the goods. I also take sturgeon liver oil. I won't tell you about its effects. But as for the price, Boss, you must know that cod is very expensive. A pound of sturgeon meat may cost hundreds of yuan, so the price of this sturgeon liver oil is naturally higher than that of ordinary cod liver oil."
Xiang Yang raised his eyebrows.
Chen Qingsheng said, "Our boss is engaged in deep-sea fishing. He is the captain and I am the first mate." The implication was that they should stop talking nonsense and they knew the price of sturgeon very well.
"Ah? Are you doing deep-sea fishing?" The shop owner was obviously stunned.
Xiang Yang nodded.
The boss said quickly, "That's great. Many people on ocean-going ships come to me to buy fish oil. I will definitely give you a fair price. Genuine sturgeon liver oil is 70 yuan per pound. I think this price is not too high for you, right?"
Xiang Yang raised his eyebrows. Seventy yuan was only enough to buy one box of sturgeon liver oil.
A pack of 60 capsules of cod liver oil from the well-known brand Kingise costs 124 yuan.
This barrel of sturgeon liver oil only costs 70 yuan, which is really not expensive.
"How many pounds does a barrel weigh?" Xiang Yang asked.
"A bucket weighs more than 29 kilograms, and a bucket with it weighs a little more than 30 kilograms." said the shop owner.
"Can you give me a normal taste?" Xiang Yang asked.
"Of course." The shop owner led Xiang Yang to the cashier, "I have some already opened barrels, you can come and try some."
"No thanks." Xiang Yang refused: "Open me a new barrel, and I will take it directly if it is genuine."
"Okay." The shop owner quickly climbed onto the shelf and took a plastic bucket down for Xiang Yang.
Xiang Yang first looked at the color of the cod liver oil in the bucket. It was golden yellow and very beautiful, just like flowing gold.
Then Xiang Yang put his nose close to the mouth of the barrel and sniffed, and immediately smelled a strong fishy smell.
Xiang Yang scooped out a spoonful with a disposable spoon and put it into his mouth.
It has an indescribable strange taste and is very difficult to swallow, just like drinking the bubble water vomited by crabs.
"How is it? Boss, does it taste good?" the shop owner looked at Xiang Yang and asked.
Xiang Yang looked at Chen Qingsheng, "Old Chen, would you like to try it too?"
Chen Qingsheng nodded and took a disposable spoon to scoop a spoonful of golden cod liver oil from the bucket.
After tasting it, he nodded to Xiang Yang and said, "This is the taste."
"Don't worry, the cod liver oil here is guaranteed to be genuine, otherwise I wouldn't dare to give it to you to try, right?" said the shop owner with a smile.
Xiang Yang nodded, "Can I transfer the money via mobile phone? I'll take two barrels of this sturgeon liver oil."
