Is there any basis for saying that high-quality tremella is better than bird's nest?

There is a folk saying that "the rich eat bird's nest and the people eat tremella", which means that the nutritional effect of tremella is comparable to that of bird's nest, and the price is not expensive, so the people can afford it. Because many tremella on the market are cheap and rough, the nutritional value is naturally inferior to that of bird's nest, but high-quality tremella such as Jin Yan Ear is ok. In addition, bird's nest is animal collagen, and tremella is plant collagen, which is more easily absorbed by human body than animal collagen. Moreover, animal collagen is easy to make people fat and induce hypertension, hyperlipidemia and hyperglycemia, which is not suitable for long-term consumption, while tremella can be eaten for a long time. Another advantage of high-quality tremella over bird's nest is its natural gum. 6 grams of dried tremella fuciformis is cooked 1 hour, and the glue solution reaches 500-600 ml, while 6 grams of dried bird's nest is also cooked 1 hour, and the glue solution is only 120 ml. Let's talk about bird's nest first. There are two main reasons for the high price of bird's nest. First, in the middle of the Tang Dynasty, bird's nest, as an overseas treasure, went to the Central Plains court. Because the bird's nest itself is slightly fishy and tasteless, even the best chef can't do anything about it. In order not to be implicated, the chef had to brag to the emperor about the benefits of eating bird's nest, such as: eating bird's nest can prolong life, tonify kidney and strengthen stomach, how to brag; In this way, the emperor was very happy. He really thought bird's nest was a good thing. From then on, the bird's nest "salted fish turned over" and directly became a must-have dish for the royal family; Bird's nest is also highly respected by elites such as dignitaries and giants, so it has the status of bird's nest now, but in fact, bird's nest itself does not have particularly high nutritional value and efficacy. Second, because bird's nest can only be produced by swallows, the efficiency is extremely low. Because it is rare, everyone is keen to buy it, so the price will be inflated. From the composition analysis, bird's nest has certain nutritional value, but it is out of proportion to its expensive price. Therefore, it makes sense for amateurs to eat bird's nest and experts to eat tremella.
