Osteoporosis? Maybe it’s because you eat too much meat!

Meow Planet is a beautiful and magical planet. There are three different energies guarded by three guardian cats, namely Tom Cat who guards protein, Garfield Cat who guards fat, and Black Cat Sheriff who manages carbohydrates. These three cats think that the energy they guard is the most important, and they all want to be the head of energy. Now, 2013 has arrived, and the three-yearly election of the head of energy cat on Meow Planet is about to begin again. This time they decided to invite their good friend Doraemon from Earth to be their judge and select the final head of energy cat. Since learning that he can come to Meow Planet as a judge, Nobita is happier than Doraemon. He just learned about energy before, and Nobita just wanted to see what magical things can provide energy. The spaceship landed on Meow Planet, "Here we are! Doraemon, who are we going to visit first?" Nobita asked excitedly. "Well, let me check the map first~ We are close to Tom Cat who is guarding protein, so let's go to Tom Cat first!" "Hi! Doraemon, my old friend! Welcome!" Tom Cat warmly received Doraemon and Nobita. Doraemon said with a smile: "You three are really dishonest, fighting over the head cat again?" "You said that Garfield and Black Cat Sheriff must fight with me, the importance of the protein I guard is not comparable to those two, hey, it's just right that you are here, hurry up and judge!" Tom Cat said while serving Doraemon and Nobita protein powder drinks. Doraemon still smiled and said, "Let Nobita do the judging job this time. Nobita will interview you and you just need to explain it clearly!" Nobita almost spit out a mouthful of protein powder drink and waved his hands hurriedly, "No, no, I don't know anything!" "That's why I ask because I don't know. Don't be afraid. Tom Cat and I are old friends. Just ask whatever you want to know!" After that, Doraemon sat comfortably on the sofa and drank a drink. Nobita: Brother Tom Cat, seeing that you are full of confidence in this selection of the head cat, I know that the protein you guard must be outstanding. Can you introduce the importance of protein? Tom Cat: The protein I guard must be the most important! Want to know why? There is a celebrity on your planet, named Engels, who once said: Protein is the material basis of life, and life is the way of existence of protein. Look, it is the basis, the way of existence of life, how can it not be important! Seeing Nobita looking at himself with a confused face, Tom Cat drank a sip of drink and continued to explain the importance of protein in detail. Tom Cat: Nobita, your heart, liver, spleen, lungs, kidneys, your nose, eyes, your bones, and even your teeth all contain a lot of protein. Protein is an important component of the body's tissues and organs. All tissues and organs of the human body contain protein. Your body is getting stronger and taller, which is also a process of continuous accumulation of protein, so protein is especially important for children in the growth and development period. Nobita: Amazing! Doraemon, I never knew that protein is all over my body! Tom Cat: That's not all. Protein also has the function of regulating physiological functions. Don't you understand again? Let me give you another example. Enzyme protein promotes food digestion, absorption and utilization; immune protein maintains the body's immune function; contractile protein, such as myosin, regulates muscle contraction... Nobita: So that's it! It turns out that the normal operation of my body is inseparable from protein! Tom Cat: Haha, that's not all! Also, since we are guarding energy, protein must also have the function of providing energy. However, we have already talked about so many important functions of protein. Providing energy can be completely left to fat and carbohydrates. Providing energy is only a secondary function of protein. Nobita: In other words, the important functions of protein include: forming body tissues, regulating physiological functions and supplying energy. Nobita wrote in the notebook while talking. "Yes, that's right!" Tom Cat turned back to Doraemon and said, "Hey, old buddy, Nobita is smarter than you thought, haha!" Nobita scratched his head embarrassedly and continued to ask with a red face. Nobita: Those who sell health products in the store often mention a word called amino acid, so what is the relationship between amino acid and protein? Tom Cat: Amino acid is the basic unit of protein. In other words, protein is composed of amino acids. So amino acids are very important for protein, which is related to the quality of protein absorption by your body. Nobita: Then how to judge whether the protein in a certain food is high-quality and can be absorbed by the human body? Tom Cat: This question is a bit complicated, I will explain it slowly. Just now you already know that protein is composed of amino acids, then there are many types of amino acids, 9 of which cannot be synthesized in the human body and must be obtained through food and other external intake. We call this essential amino acid. If a food has a complete range of essential amino acids, and the composition of amino acids is close to the essential amino acid requirement pattern of the human body, and the utilization rate in the human body is high, then the protein in this food is called high-quality protein. In addition to high-quality protein, the human body cannot absorb and utilize other proteins well, such as those with an inappropriate ratio of essential amino acids or incomplete essential amino acids.
Nobita: I didn't expect that there is so much knowledge about protein! Thank you so much, Brother Tom Cat, for telling me so much about protein. Nobita and Doraemon said goodbye to Tom Cat. When Tom Cat sent them to the door, he didn't forget to shout: Hey, old friend, when I become the head cat of energy, I will give you two a box of protein powder! Nobita muttered: "I am so healthy, and you take care of me. I can supplement enough protein with a normal diet. I don't need protein powder at all. Those patients and wounded who have surgery need it~right Doraemon?" Doraemon happily took Nobita's hand: "Nobita, you are amazing! It seems that you already know all the relevant knowledge about protein. Let's go and see what Garfield and the fat he is responsible for looking after look like." The afternoon sun on the cat planet is bright, the lake in the distance is sparkling, and the whole cat planet looks quiet and peaceful. Next to the lake lives Garfield, and there is the energy guarded by Garfield - fat.
