Sugar and oil are indispensable nutrients for human life. The three nutrients in the human body include: protein, fat and carbohydrate, namely sugar.
Our understanding of these three macronutrients determines our understanding of nutrition, nutrition and health. It also determines whether we can help others, adjust various chronic diseases and restore health.
The health of body and life is not the research and development of drugs, nor the high-tech surgery and advanced medical equipment.
But return to the food nutrition that is inseparable and closely related to our lives. The research obtained the indispensable nutrients in our daily life. Because each of us is made up of nutrients in food, we grow, maintain health and maintain existence.
These nutrients closely related to life are replaced: protein, fat, carbohydrates, vitamins and minerals, plus water and dietary fiber.
Studying this is the way out and the direction. Of course, this is the material basis for the healthy existence of life. On this basis, health will be affected by other factors.

Today, let's talk about sugar and oil.
Sugar is carbohydrate, including monosaccharide and disaccharide, such as polysaccharide. Monosaccharide such as glucose, disaccharide such as maltose, polysaccharide such as starch.
The sources of sugar are rich and varied in nature, all in the form of complexes, and the form of monomer sugar is rare.
Sugar is the main energy source of human body, accounting for about 60~70% of human energy supply normally and reasonably. The energy supply of residual fat is about 20~30%, and protein accounts for about 10~ 15% of the energy supply.
Why do humans choose carbohydrates as the main energy source? This is the result of natural selection in environmental evolution. Because sugar exists widely in nature and is easy to get.
In addition, sugar foods are usually easy to digest and absorb, which can quickly provide energy sources for the body, quickly replenish body energy, and quickly maintain blood sugar stability.
In addition, the final products after sugar is used and metabolized in the body are water and carbon dioxide. Will not cause too much metabolic burden to the body. It can be understood as a very clean and pollution-free energy source.
These three points are very important. Not fat, protein has an advantage as an energy source.

The human body's demand for energy is endless and cannot be interrupted. The so-called snack is aimed at sugar.
If you are not a manual worker, you will eat too much polysaccharide at once, and your body will not use it in a short time. Excess sugar will be converted into liver sugar and stored in the body together with fatty acids. In case of emergency, otherwise it may cause obesity, hyperlipidemia and fatty liver.
Now people eat different carbohydrates than before. It used to be coarse grains, all of which were rough and natural sources. Now people eat carbohydrates, including rice, pasta, steamed bread, steamed buns and so on. , are sources of refined sugar. This does not match the health and needs of the body.
Sugar is sticky and oil is slippery. What really causes cardiovascular diseases is not oil, not fat. It is caused by excessive refined sugar.
Too much sugar will stick to fatty acids, cholesterol and other substances in blood vessels, leading to cardiovascular and cerebrovascular problems.
Glycosylation is also the cause of arteriosclerosis and plaque. Because sugar will harden after peroxide, and oil doesn't need to harden.
In daily life, what we really need to pay attention to is the source of excessive, excessive and uneven intake of excessive sugar. This factor is not easy to detect, but it is far-reaching.
Stay away from refined sugar, high carbohydrate and high starch intake are problems that modern people must pay attention to.

Grease is the protective layer and substance of the body.
Every cell membrane, tissue membrane, articular membrane and every tissue and organ of the body need a film made of fat for protection, isolation and lubrication. It is the existence of fat that can isolate and protect the connection between life and the outside world and form the internal environment of life.
It is also the existence of fat that keeps the body temperature of tissues and organs well.
Fat is the choice of natural animals to store energy. Animals will store fat as much as possible before the arrival of winter, so that when food is scarce in the long winter, there is enough energy to support the basic metabolism of life and maintain body temperature.
Naturally, fat is chosen as the energy source, because fat has a high price of energy and heat. 1g fat can produce 9 kilocalories, which is more than twice that of carbohydrates and protein.
Think about it, if you choose sugar as the storage source, your weight and volume need to be more than tripled.
In the actual daily diet, not many people really eat good oil. Observe the people around you. How many people are really big fish and big meat?
Plus, most people hear it from hearsay, and being fat is a bad thing? Is the culprit of cardiovascular and cerebrovascular diseases? I will talk more about my diet and dare not eat fat.
Fat is the structural and protective raw material of the body. Body life needs fat as protection, nutrition and lubrication, in order to maintain energy for a long time and not be harmed by foreign substances such as toxins, bacteria and viruses.
Fat determines a person's degree of protection, which means that fat determines a person's degree of aging.
