The whole world can't stop the temptation of sugar.
Sucrose is one of the basic food additives for human beings, which has a history of thousands of years. The word sugar, which is commonly used all over the world, actually comes from Sanskrit sakara, indicating that sugar originated in ancient India and was introduced to China and other parts of the world through the Silk Road. There is a passage in the Remnants of Dunhuang that records the Indian method of making sucrose, to the effect that the juice extracted from sugarcane is dried in the sun to make syrup, and then boiled with fire to become Sakala. This is the earliest history of sucrose. According to historical records, the earliest candy appeared in ancient Rome. People wrap almonds with honey and dry them in the sun to get sugar-coated almonds. In China, since the establishment of the Western Zhou Dynasty, the early sugar product-caramel has been widely circulated among the people and widely eaten.
For thousands of years, people of different colors and races have different eating habits, but they have a special liking for sugar, which all stems from the role of "sweetness". The study found that "sweetness is the taste of breast milk", which is one of the reasons why taste buds like sweetness; When eating sweets, it will activate dopamine neurons in the brain and make people feel excited; Sweetness can provide energy for the body. After entering the blood, it will lead to an increase in blood sugar content, prompting the pancreas to secrete insulin quickly and convert blood sugar into energy. Sweetness can also relieve stress. Studies have shown that digestible carbohydrate desserts can increase the level of serotonin in the human brain, and its effect is equivalent to that of antidepressants. ...
Therefore, the consumption of sugar is increasing. According to the analysis report of sugar industry in 20 13, the global sugar demand in 20 13 is about 654.38+64 million tons. In the past 20 years, the compound growth rate of global sugar consumption was 1.8%, and China reached 2.9%, among which beverages, sweets, frozen food and canned food became the main sources of sugar consumption. The per capita annual consumption level of sugar in the world is 2 1.66 kg, and the per capita daily intake is about 59 grams, far exceeding the upper limit of 50 grams recommended by WHO in 2002. According to a survey conducted by the French National Candy Association, 1 in every three adults is a sweet tooth lover.
Sugar addiction is more harmful than smoking.
The temptation of sugar is hard to resist, but eating too much is unhealthy. After investigating the causes of death in 23 countries, the World Health Organization concluded that sugar addiction is more harmful than smoking. This survey shows that the average life expectancy of long-term high-sugar diet is shorter than that of normal diet 10~20 years.
Such statistics confuse many people: obviously, there are more and more people who are afraid of obesity in their lives, and they always think twice before eating sugar. How can it lead to high sugar intake? According to Wang Donglan, an associate professor in the Nutrition Research Office of the Academy of Military Medical Sciences, people eat too much sugar, which is largely due to restaurant dishes and processed food. For example, Sean, a national senior chef, said that one serving of braised pork contains 40-50g sugar, Wuxi sparerib contains 75g sugar, and fish-flavored shredded pork contains 25-30g sugar. In the supermarket, there are many sugary families such as sweet drinks and sauces. There are all kinds of "invisible sugar" hidden in bread, plum and yogurt. For example, Hua Xin, a nutritionist at Beijing Friendship Hospital, said that snacks such as preserved plum will add a lot of sugar to inhibit the growth of bacteria and thus prevent spoilage.
Experts say that if you eat too much sugar, you will feel full because you eat too much energy, which will affect your intake of other foods rich in protein, vitamins, minerals and dietary fiber. Many foreign studies have confirmed that the harm of eating sugar far exceeds people's imagination.
Disordered cholesterol. A study in the Journal of the American Medical Association found that people who eat the most sugar also have the highest levels of bad cholesterol and triglycerides. Too much sugar will not only produce bad cholesterol in the liver, but also inhibit the metabolism of bad cholesterol in the body.
The risk of cancer will increase. A study of postmenopausal women found that people with high blood sugar levels have almost twice the risk of rectal cancer. Other studies have found that people with high blood sugar are more likely to develop liver cancer and breast cancer.
Induce heart disease. Mallota, an expert member of the Obesity Group of the Royal College of Medicine in London, said that sugar can increase uric acid in human body and increase the incidence of hypertension, thus increasing the risk of heart disease and stroke.
Attract diabetes. It is found that as long as a person consumes 150 calories converted from sugar every day, the risk of diabetes will be higher than 1. 1%. If you are already a diabetic, sugar will cause more trouble.
Cause a headache. Dr Andy andy dawson, a headache expert at King's University London, UK, pointed out that when you eat too much polysaccharide, your body needs to react quickly, and the blood sugar level will suddenly reach a peak and then fall into a trough, which may lead to a headache.
Suffer from fatty liver A study by the University of Washington found that excessive intake of sugar increases the risk of fatty liver. Long-term high-sugar diet will accelerate the storage of fat in liver cells, leading to the accumulation of fat around the liver.
Damage memory. Neuroscientists at the Chariot University Medical Center in Berlin, Germany, found that eating sugar not only damages the physical structure of the brain, but also damages its function. Eating too much polysaccharide may lead to cognitive impairment.
Causing premature death. The US Centers for Disease Control and Prevention analyzed the data of more than 30,000 people. The results showed that people whose total calories exceeded 2 1% a day came from adding sugar, and their risk of death due to heart disease was 1 times higher than those whose intake of added sugar was less than 10%.
Sugar should be controlled like tobacco.
Robert Rustin, an endocrinologist at the University of California, appealed that sugar is more harmful to health than obesity, because sugar is not only toxic, but also addictive, and excessive intake is like chronic suicide. In recent years, the United States has taken many measures, from restricting the sale of sweet drinks around campus to restricting the listing of large bottles of sweet drinks in new york. In China, some cities have also begun to implement measures that schools cannot sell carbonated drinks and other unhealthy foods and drinks. In addition, it is also an urgent problem for all countries to control the sugar used by food enterprises and regulate the amount of sugar put by chefs through policies.
In March this year, WHO publicly solicited opinions on the draft guidelines for sugar intake, suggesting that the daily sugar intake of adults should be controlled at 5% of the total energy intake of the day, about 6 teaspoons and 25 grams. Wang Donglan said that it is difficult to meet this standard, but at least we should start from changing our concepts, such as actively reducing blood sugar, starting with a weekly hypoglycemic meal and eating less sugary food every day. After a long time, the taste will fade. You can also choose substitutes, such as fruit instead of candy, honey instead of sugar, and orange peel and lemon juice instead of sugar flavor when cooking. In addition, reducing eating out and eating at home can better control the amount of sugar. Finally, experts said that to stay away from "invisible sugar", we should learn to read the labels of processed foods. We must buy less or even no food with the words white sugar, granulated sugar, sucrose, fructose, dextrin, etc.
