This question is specious. High fat certainly comes from high calories, but strangely, only Americans can eat fat. Those foreigners with normal bodies, regardless of their blue eyes and big noses, must be from the third world. Before going to the United States, I had a question: Under the influence of overwhelming junk food, will Chinese people become American-style fat people? Now I know: Absolutely not. An unexpected fact is: the degree of obesity in a country is inversely proportional to the taste of food. This sounds illogical. Doesn't it mean "if it tastes good, just eat more"? How could it be possible that the more unpalatable it is, the more appetizing it becomes? In fact, the reason is very simple: after eating bear paws and fish, no one will ever be willing to swallow vegetables again. Chinese people have long had a tricky tongue; only those Americans who were born and raised would consider pig food a delicacy. Carefully prepared delicacies are either too expensive or too time-consuming to eat, and you won’t gain weight; while salads with chopped lettuce and tossed, and pizzas that can be made by pressing a button are really suitable for those who have no taste at all. Fat boy. All Americans are fat because they don’t have good food to eat. This is by no means to say that there is no good food in America. On the contrary, this place brings together classic cooking techniques from all over the world, as long as you are not afraid of eating up a month's salary in one meal. Things are rare and valuable, and there are so few good chefs that, except for professional chefs in restaurants, few people in the country know how to cook. So what do the general public do on a daily basis? Method 1: Make your own adjustments; Method 2: Buy things that are mass-produced and packaged for sale, historically known as junk food. KFC and McDonald's are called junk food, which is unjust, because there are even more junk foods. Think about it, if KFC chicken was tastier than the chicken made by the American people, wouldn’t it have been closed down long ago? Compared with Americans, all Chinese are chefs, so the food is extremely cost-effective. American home-cooked meals do not have any technical content. The migrant workers in China who fry box lunches on the roadside have the right to look down on Americans. Since Americans generally don’t know how to burn, why do Chinese people do it? We have come to another conclusion: the popularity of a country's food is directly proportional to its history. Tofu, soy sauce, braised pork, egg fried rice, these genius inventions of ancient China have been passed down from generation to generation. For thousands of years, we have plagiarized the achievements of these unknown heroes without even paying patent fees. The United States has only been founded for more than 200 years and is purely a country of immigrants. A more convincing example is that Australia, another immigration country, is also rich in super fat people. However, when we laugh at American food, we are actually making a mockery of it. What would happen if you and I were immigrated to an alien planet? Think about what we all ate when mom was away. Maybe a hundred years later, another planet of egg fried rice and instant noodles will be born. Some people may say, won’t people invent new delicacies? Look at the example of the United States. For hundreds of years, it’s just hamburgers and sandwiches! But after all, what innovation has China’s braised pork had? We are close to the essence of the problem. Whether it’s hamburgers or braised pork, almost no one is willing to change! Most people just repeat themselves. If American food is lackluster, then where does the food that Chinese people are proud of come from? It's either the invention of a genius, or it's just a coincidence. Have you ever thought of adding gypsum to soy sauce? Have you ever thought of mixing yeast into flour? If no one taught you, would you eat food freely with two sticks instead of tearing it with your hands and teeth? Besides food, isn’t it the same with everything else? Some people say that even if Edison hadn't been there, someone else would have invented the light bulb. I believe so. But maybe we will wait a long time, maybe we are still living by candlelight, because the number of geniuses is much less than we expected. Only insight beyond the times, extraordinary courage, and unyielding determination can change the world and create the future. Otherwise, we will always be stuck in the same place. Let’s change our perspective and look at biology. Human evolution comes entirely from mutation. Without mutations, humans today would be just like their ape ancestors one million years ago. All modern human genes can be traced back to mutations in one person hundreds of thousands of years ago. This does not mean that there was only one person on Earth at that time, but that everyone else became extinct and only his/her genes survived to this day. Maybe in hundreds of thousands of years (if humans still exist), only one gene will survive among 6 billion people. This is a cruel reality. If we attribute the evolution of civilization to mutations, such as the emergence of genius and accidents, then we will get the same cruel reality: the vast majority of people will be the burial objects of history. They are born just to wait for a small probability event to happen. They are copies of the past and they will not have any impact on the future.
