Which is more nutritious, fish or fish soup?
Popular science benefits people's livelihood and life is easier. Welcome to "One-stop Science Popularization" jointly organized by Zouping Association for Science and Technology and our station. I believe many citizens like to drink fish soup. Some people don't even eat a piece of fish after stewing it. Others only drink fish soup, because in their view, most of the nutrition of this fish is put into fish soup when stewing fish, and the soup has higher nutritional value. Is that really the case? Is the nutritional value of fish meat or fish soup high? At the beginning of the program, let's listen to your opinions first.

Interview: I think (fish) soup has higher nutritional value.

Interview: Personally, I think this fish soup is more nutritious for you to stew fish.

Interviewer: I think fish soup still has high value, because all the nutrients are in the soup when it is stewed, so I think fish soup has high value.

Interview: I think fish soup (with higher nutrition) takes a long time to boil fish soup, and the nutrition of fish (meat) is boiled into the soup.

Interview: I think fish is more valuable.

Interview: I think fish should be more valuable than fish soup. Why? Because this fish soup is stewed with fish, no matter how it is stewed, it will not exceed the nutritional value of fish. I thought the same thing.

It seems that quite a few people still think that this fish soup has higher nutritional value. What nutrients are there in the fish soup?

Interview: (Nutritionist Cheng Guangxuan) When we stew fish, the fat contained in the fish will dissolve into the soup, and some water-soluble protein in muscle tissue and lecithin in bone will also dissolve into the soup. In addition, collagen in fish skin will also be hydrolyzed into gelatin molecules. Therefore, fish soup only contains fat, a small amount of protein and some collagen, and most of the fish's nutrients, such as protein and minerals, are in the fish. So, if you eat fish,

From this perspective, if you want to get adequate nutrition, you should not only drink fish soup, but also eat fish. What should I pay attention to when stewing fish? How long does it take to stew fish?

Interview: (Nutritionist Cheng Guangxuan) I suggest that if the main purpose is to eat fish, cook the fish before putting it, but if the fish soup is delicious, put the fish in cold water. In addition, the time for stewing fish is generally 20-30 minutes from boiling, because the time is too short, the fat and water-soluble protein of fish are not decomposed enough, the fish soup is not delicious, and the flavor of fish will be greatly reduced if the time is too long.
