食品級葡萄糖和果糖的不同之處是什么你了解嗎？

研究發(fā)現(xiàn)，飲用果糖飲料的志愿者血液中LDL和甘油三酯的含量明顯高于飲用葡萄糖飲料的志愿者。這兩種物質(zhì)都是心血管疾病的重要誘因。與此同時，果糖組的胰島素敏感性也降低了，增加了患糖尿病的風險。果糖更容易導致心血管疾病。為首的一個研究中,彼得·哈維博士在美國醫(yī)療網(wǎng)絡(MedicineNet.Com)告訴記者:“現(xiàn)在大多數(shù)人的消耗過多的果糖飲料,我們看到了10周的實驗只喝對身體損害,事實上,人們喝的時間遠遠超過10周,有些人甚與大量的果糖喝飲料。”另一位領(lǐng)導人吉姆·波勒·斯坦霍普建議人們少喝酒。
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，科學家還發(fā)現(xiàn)果糖和食品級葡萄糖在體內(nèi)的代謝方式不同。食品級葡萄糖在肝細胞中轉(zhuǎn)化為甘油，甘油是一種合成脂肪，通常由磷酸果糖激酶控制，但果糖不是，所以它可以轉(zhuǎn)化為甘油，這是合成脂肪所需要的。當果糖攝入量較低時，果糖可以轉(zhuǎn)化為葡萄糖，從而增加肝臟中的糖原儲存。當大量攝入果糖時，它就成為脂肪合成的原料。
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.
食品級葡萄糖是自然界中分布更廣、更重要的單糖之一(多羥基醛或多羥基酮，不能水解)。葡萄糖是活細胞的能量來源和代謝的中間產(chǎn)物，占人體血糖的80%。植物通過光合作用產(chǎn)生葡萄糖。果糖是一種單糖，存在于許多食物中，包括蜂蜜、水果、瓜類和根莖類蔬菜，如甜菜、土豆、蕪菁和洋蔥。
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.
