High Carbohydrate in Diet Linked to Cataract Formation高碳水化合物的飲食聯繫在一起的白內障形成

Allen Taylor, Ph.D., at Tufts University and colleagues reported that carbohydrate intake in older nondiabetic persons is related to the development of nuclear and cortical lens opacities.李鵬飛泰勒,博士,在塔夫茨大學和他的同事報告說,碳水化合物的攝入量在較舊的nondiabetic人是發展有關的核和皮質晶狀體混濁。

The present study suggests a positive relation between the dietary glycemic index and nuclear opacities.目前的研究表明,積極的關係,飲食血糖指數和核混濁。 It is possible, that foods with a higher glycemic index may increase the damage to the metabolically limited nuclear tissue of the lens by exposing the tissue to glucose for longer periods.是有可能的,即食品具有較高血糖指數可能會增加破壞了新陳代謝的有限核組織的鏡頭暴露的組織,以葡萄糖為更長的時間。

The glycemic index measures how fast a carbohydrate can raise blood glucose and may better describe the physiological effects of carbohydrates than the total quantity of carbohydrate intake, said .血糖指數的措施,如何快碳水化合物,可以提高血糖,並可能更好地描述生理效應的碳水化合物比總量碳水化合物的攝入量,說。

These findings add to an evolving biochemical, animal-based hypothesis that dietary carbohydrates may be associated with cataractogenesis, Dr. Taylor said.這些調查結果添加到一個不斷演變的生化,動物為基礎的假設,即碳水化合物飲食可能與白內障,博士泰勒說。 Prior evidence of cataract-related damage to lens proteins includes glycation, oxidation, cross-linking, and formation of advanced glycoxidation end-products, for example.之前的證據,與白內障有關的損害晶狀體蛋白包括糖基化,氧化,交聯,形成先進的glycoxidation終端產品,例如。
