There is little difference in nutritional value between sea bass and sea bass, both of which contain a large number of protein, vitamin A and vitamin B groups, as well as various nutrients such as calcium, zinc, magnesium and selenium, among which the content of copper is also relatively high, and both belong to sea bass species with high nutritional value. Therefore, the two kinds of bass have their own characteristics, only the differences between their varieties and the differences between the markets, so it is not easy to tell which one is better.
Sea bass are cheap because they are all stale sea bass, fresh sea bass are not cheap, and high-quality sea bass are very expensive. Many mainlanders often eat frozen seafood and find that seafood is very cheap, but really eating fresh seafood at the seaside is extremely expensive, which is the difference brought by quality, while river bass is cheap because there are more people breeding it.
Sea bass is a kind of seafood. Now, some sea bass buy 18 yuan a kilo, while sea bass buy 15 yuan a kilo, which shows that sea bass is frozen, and the price of fresh sea bass is not low, so it is normal to buy more than 90 yuan a kilo. So don't ask why sea bass is cheap, but look at where it was bought. If you eat fresh sea bass at the seaside, the price will definitely be very expensive.
If you buy frozen sea bass in the supermarket, the price will not be too expensive, and the frozen sea bass will taste worse, without the taste of fresh sea bass, and the nutrition will be greatly reduced.
You should know that sea bass itself is a very nutritious fish, which can not only tonify the body, but also tonify the kidney and liver. Moreover, it has less fat and will not gain weight after eating too much. It is very delicious to steam.
