Do nucleic acid health products have any effect? There was a lot of talk in the news media not long ago. Although the Ministry of Health has given necessary answers to this, people still hope to have more and more scientific understanding of nucleic acids and their health care effects. Some readers also wrote to ask for an introduction to this topic. The nutritional role of nucleic acids is a scientific issue, and science needs to be understood by the public. Scientists need to explain scientific knowledge to the public. This newspaper selects and publishes academic articles by some experts for readers' reference only. We hope that more people can comprehensively understand nucleic acids from a scientific perspective and learn about the progress and progress of new technologies. Understand the development of emerging industries, and welcome experts in the field to express their opinions.
1. What are nucleic acids
Nucleic acids are divided into two categories: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). Like proteins, they are biological macromolecules that make up human cells. Composed of bases, ribose and phosphate. Bases are divided into two types: purine and pyrimidine. A base connected to a ribose is a nucleoside, and a phosphate is connected to a nucleotide. Many nucleotides are connected in a certain order to form a nucleic acid. Nucleic acids have the function of encoding genetic commands and carrying genes; however, endogenous and exogenous bases, nucleosides, and nucleotides have no genetic function and do not carry any genetic information. They have many physiological and nutritional functions.
2. Food nucleic acids can be digested and absorbed, exert nutritional effects, and have no genetic functions
Nucleic acids in food are degraded by enzymes that originally exist in the intestines and become without genetic functions. Bases, nucleosides, and nucleotides. It is these three substances that are actually absorbed by nucleic acids in food, not nucleic acids with genetic functions. When people eat rice and noodles, they do not directly absorb carbohydrates, but absorb their degradation product glucose; when they eat meat and eggs, they do not directly absorb protein, but the degradation product of protein, amino acids; when they eat fat, they absorb the degradation product of fat. Glycerin and fatty acids, etc. But we do not refer to eating protein as eating amino acids, nor do we refer to protein nutrition as amino acid nutrition. The bases, nucleosides, and nucleotides digested and absorbed from food are no different from endogenous similar substances in composition, structure, and function, and they also play physiological and nutritional roles. Therefore, nucleic acids can be digested, absorbed and converted into physiological substances and nutrients; nucleic acid foods are not genetic foods.
Development and Utilization of Nucleic Acid Food

Nucleic acid is the key to life Source, nucleic acid nutrition and nucleic acid food are currently hot research topics in the medical community. They are related to the most closely related issues to human beings such as the extension of human lifespan, the prevention and treatment of diseases, food production and family planning. Some scientists believe that nucleic acids are the nutrients of the 21st century.
1. Deoxyribonucleic acid (abbreviated as DNA damage is the primary factor in human aging)
2. DNA and anti-aging
3. DNA in humans It can be synthesized in the body and can also enter cells through diet
4. Nucleic acid nutrition is popular all over the world
In recent years, people have become increasingly aware of the nutritional properties of nucleic acids and the anti-aging properties of nucleic acids. Nucleic acid nutrition Popular around the world. According to the prediction of the American scientific community: by 2025, nucleic acid gene nutritional products will account for 20% of the U.S. gross national product. Currently, the United States is studying nucleic acids as drugs to prevent and treat cancer and AIDS, and some of them have already been put on the market. France and the United States successfully developed nucleic acid nutritional products almost simultaneously. In the early 1980s, a variety of nucleic acid drugs were produced and recommended to the international market. Because nucleic acid can absorb ultraviolet rays, it can prevent dark spots, spots, tan spots, and age spots, and has functions such as moisturizing, inhibiting sebum secretion, activating cells, and softening the skin. In recent years, it has been made into many cosmetics and is very popular.
Japan has been conducting research and development on nucleic acids for at least 30 years.
The Japan Institute of Molecular Integrated Medicine and Nutrition extracts di-nucleic acid supplement food from yeast, extracts a variety of nucleic acid additives from fish sperm and animal organs, and produces nucleic acid condiments, nucleic acid bread, nucleic acid tofu, nucleic acid brain-building hormone, nucleic acid bodybuilding hormone, Nucleic acid robustins, etc., sell well in China and Southeast Asia. In 1988, "Nihon Shinyaku Co., Ltd." also applied for a patent in China using nucleic acids as anti-cancer and anti-viral agents. Japan's nucleic acid preparations are in short supply, especially middle-aged and elderly people, who attach great importance to nucleic acid nutrition.
5. Nucleic acid supplementation
Since the 1980s, the international medical community has advocated nucleic acid nutrition. It is recommended that in daily meals, try to consume some natural foods rich in nucleic acids, such as marine fish, seafood, animal liver, beans and their products, yeast, mushrooms, aloe vera, cactus, fungus, pollen, cauliflower, carrots, onions, leeks, Onions, spinach, cabbage, mustard greens, asparagus, radish, etc., making full use of natural foods rich in nucleic acid, are important sources of nucleic acid. In addition, they can also be supplemented by some industrialized products of nucleic acid.
