研究发现，饮用果糖饮料的志愿者血液中LDL和甘油三酯的含量明显高于饮用葡萄糖饮料的志愿者。这两种物质都是心血管疾病的重要诱因。与此同时，果糖组的胰岛素敏感性也降低了，增加了患糖尿病的风险。果糖更容易导致心血管疾病。为首的一个研究中,彼得·哈维博士在美国医疗网络(MedicineNet.Com)告诉记者:“现在大多数人的消耗过多的果糖饮料,我们看到了10周的实验只喝对身体损害,事实上,人们喝的时间远远超过10周,有些人甚与大量的果糖喝饮料。”另一位领导人吉姆·波勒·斯坦霍普建议人们少喝酒。
The study found that the blood LDL and triglyceride contents of the volunteers who drank fructose beverage were significantly higher than those who drank glucose beverage. Both substances are important inducers of cardiovascular disease. At the same time, the insulin sensitivity of fructose group also decreased, increasing the risk of diabetes. Fructose is more likely to cause cardiovascular disease. In the first study, Dr. Peter Harvey told reporters on the American Medical Network (medicainet. Com), "now most people consume too much fructose drinks, we see that 10 weeks of experiments only drink physical damage, in fact, people drink far more than 10 weeks, some people even drink with a large amount of fructose." Another leader, Jim Bole Stanhope, advises people to drink less.
此外，科学家还发现果糖和食品级葡萄糖在体内的代谢方式不同。食品级葡萄糖在肝细胞中转化为甘油，甘油是一种合成脂肪，通常由磷酸果糖激酶控制，但果糖不是，所以它可以转化为甘油，这是合成脂肪所需要的。当果糖摄入量较低时，果糖可以转化为葡萄糖，从而增加肝脏中的糖原储存。当大量摄入果糖时，它就成为脂肪合成的原料。
In addition, scientists have found that fructose and food grade glucose are metabolized in different ways in the body. Food grade glucose is converted into glycerin in hepatocytes. Glycerin is a kind of synthetic fat, which is usually controlled by phosphofructokinase, but fructose is not, so it can be converted into glycerin, which is needed for the synthesis of fat. When fructose intake is low, fructose can be converted into glucose, thus increasing glycogen storage in the liver. When fructose is consumed in large quantities, it becomes the raw material of fat synthesis.
食品级葡萄糖是自然界中分布更广、更重要的单糖之一(多羟基醛或多羟基酮，不能水解)。葡萄糖是活细胞的能量来源和代谢的中间产物，占人体血糖的80%。植物通过光合作用产生葡萄糖。果糖是一种单糖，存在于许多食物中，包括蜂蜜、水果、瓜类和根茎类蔬菜，如甜菜、土豆、芜菁和洋葱。
Food grade glucose is one of the most widely distributed and important monosaccharides in nature. Glucose is the energy source of living cells and the intermediate product of metabolism, accounting for 80% of human blood glucose. Plants produce glucose through photosynthesis. Fructose is a monosaccharide found in many foods, including honey, fruits, melons and root vegetables, such as beets, potatoes, turnips and onions.
