New scientific discovery: more than half of the human body is not human

Saying you are not actually human? I am not insulting you, really, this is the conclusion of the latest research scientists have told you. A recent BBC science program reported that human cells make up only 43% of the total number of cells in the body, and the rest are foreign microscopic organisms. In other words, of the total number of cells that make up your life, more than half are not human cells, but others.

Professor Knight of the University of California, San Diego, explains that the human genome, that is, a person's complete set of genetic instructions, is made up of 20,000 genes, while the number of human microbial genes is between 2 million and 20 million. Compared with that, human genes are truly insignificant, so what are you so proud of? The microorganisms that make up the vast majority of the human body are related to the vast majority of diseases discovered by modern medicine, including tumors, skin allergies, Parkinson's, diabetes, high blood pressure, and so on. This discovery will certainly bring disruptive treatment methods for the diagnosis and treatment of these diseases. Because the composition of the human body, including human consciousness, your appearance, your thinking, your IQ, including your successes and failures, gains and losses, is very likely merely the will of other organisms within the human body, and you are just a loyal executor.

More and more big names in the scientific community believe that so many microorganisms not only interact with the human body, but also have many effects on the human body, for example playing a role in digestion, regulating the immune system, preventing disease, and producing important vitamins. The fate of the bacteria in the gut actually determines our own fate, so never make an enemy of them.

I personally also believe: antibiotics and vaccines have become powerful weapons against smallpox, tuberculosis bacilli, or drug-resistant Staphylococcus aureus, and have already saved many people's lives. But my concern is: while eliminating these harmful bacteria, the "good bacteria" in our bodies will also suffer greatly. In fact, over the past few decades, scientists have discovered a large increase in autoimmune diseases and allergies. The microbiome is also related to some other diseases, such as some tumors in the body, inflammatory bowel disease, Parkinson's disease, and even depression and autism. Obesity is no exception. Enjoying burgers and chocolate increases the risk of obesity, and at the same time also affects the types of microbiome in the digestive tract. So how do you know whether it is the way bad bacterial flora metabolize food that causes obesity?

Scientists once conducted experiments on mice. These mice (nude mice) were born in the cleanest environment in the world and were kept away from all microorganisms after birth. The researchers extracted bacteria from the feces of thin people and fat people, and then implanted them into different mice respectively, and as a result the mice became thinner or fatter. Moreover, the bacteria of thin people can also help obese mice lose weight. Why is it that some people gain weight even by drinking water, while some people eat fish and meat at every meal yet have a slender waist? Whether one is fat or thin is also determined by gut bacteria. Although it is not yet known whether this applies to the human body, could microorganisms be used as a new type of drug? This experiment has brought hope to scientists in this field.

How to coexist peacefully with the microorganisms in the body over the long term, rather than perishing together. The vast majority of human diseases are caused by an imbalance of gut bacteria. Scientists believe that since the cause of the vast majority of diseases has already been found, the solution must also lie in the gut. Protecting the intestinal mucosa and protecting the gut bacteria will be the most important means of maintaining human health.
