The research team of the University of Zurich and the University Hospital of Zurich published a randomized controlled experiment in which subjects drank sweet drinks containing different types of sugar every day for seven weeks.
The experimental results show that the metabolism of the subjects has changed significantly, which leads to the doubling of fat production in human liver. Researchers warn that long-term intake of these sweet drinks may lead to diabetes or fatty liver.
A cup of hand-cranked drink every day doubles fatty liver!
In this study, 94 healthy young people were included. The sweet drinks consumed by the subjects contain fructose, glucose or sucrose, which is equivalent to 80 grams of sugar per day (equivalent to about 800 ml of ordinary soda). The control group did not drink alcohol. Then, the researchers tracked the sugar in the body and its effect on lipid metabolism.
Generally speaking, participants did not consume more calories than before the study, because sugary drinks increased satiety, thus reducing calories from other sources.
However, the researchers observed that the fat production in the liver of subjects in fructose group and sucrose group was more than twice that in glucose group or control group, and this situation remained unchanged after eating or drinking drinks 12 hours.
The accumulation of fatty liver leads to an increased risk of chronic diseases and death.
What's wrong with fat hoarding? Liang Chengchao, vice president of Beitou Health Management Hospital, explained that when the calorie intake is too much, it can easily be converted into fat and stored in the liver. When liver cells accumulate too much fat, and the fat exceeds 5% of the liver, it is called fatty liver.
The evolution of fatty liver can be divided into three stages, and most people have no obvious abnormalities in early fatty liver. Most people only know that they have fatty liver through abdominal ultrasound examination during physical examination. It is not until the middle and late stage of steatohepatitis that obvious symptoms such as upper abdominal pain, loss of appetite, burnout, abdominal distension and liver tenderness may appear.
The latest research in Sweden shows that the death risk of fatty liver patients is 1 times higher than that of non-fatty liver patients, and the death risk increases with the severity of the disease.
Don't be superstitious about "healthier sugar". Sweetness intake needs * * *.
Professor Philipp Gerber, from the Department of Endocrinology, Diabetes and Clinical Nutrition, University Hospital of Zurich, who is in charge of this research, said: "Surprisingly, the sucrose we eat most often can promote fat synthesis more effectively than the same amount of fructose. 」
Until now, people still think that fructose is the most likely to cause disease and belongs to "unhealthy sugar". Recently, in particular, more and more hand-cranked beverage shops have posted notices, flaunting the use of "sucrose" instead of "fructose syrup", emphasizing that it is healthier.
Wu Yiting, a health nutritionist at Heho, said that the manufacturing methods of various sugars are slightly different, which may lead to slightly different nutritional components. "However, in general, whether it is sucrose, fructose or honey, the intake should be limited. 」
The World Health Organization recommends that the daily sugar intake should be controlled within 25 grams. Professor Philipp Gerbe further pointed out: "80 grams of sugar a day will promote the production of fat in the liver. Even if you don't consume other sugars, the overactive fat will last for a long time. It shows the long-term effects of sugar intake on health.
Prevention and inspection together! Prevention of fatty liver deterioration
At present, there are no effective drugs to treat and control fatty liver. If you want to improve fatty liver, the most effective treatment is still to adjust good eating habits, cultivate exercise habits and control weight in daily life, and arrange health checks to observe the hidden obesity in the body.
Abdominal ultrasound is a sharp tool to check the health of the liver, which can effectively diagnose the formation of fatty liver. If suspicious shadows of the liver are found, we can use zero-radiation magnetic resonance imaging (MRI) to check the specific contrast agent of liver cells, make up for suspicious lesions that cannot be found by ultrasound scanning, and completely control the health of the liver.
