認識低GI食物
唐太：「剛患上糖尿病，醫生說要注意食物的升糖指數，是否要吃無糖的食物？」
CheckCheckCin：「升糖指數」(Glycemic Index，簡稱GI）是量度各類含碳水化合物（醣質）食物在進食後對血糖影響程度的數值，食物中的碳水化合物在消化道分解後，會轉化成葡萄糖進入血液，血糖會因而上升，各種食物的轉化速度不一樣，高GI的食物較容易消化而轉化成葡萄糖，一般都是纖維含量低、精緻度高、較為稀爛的食物，例如白飯、粥、麵包、蛋糕、南瓜、薯蓉、果汁、砂糖等，故進食後容易出現高血糖情況；而精緻度低、富含膳食纖維、蛋白質的食物大多屬於低GI，例如糙米、燕麥、全麥麵包、意粉、蘋果、粟米、白扁豆、紅腰豆、牛奶、乳酪等，延長飽足感時間，有助控制血糖。
從中醫角度來看，低GI食物多為粗糧，故建議平日多食用，包括全穀類食品，例如燕麥、藜麥、蕎麥、小米、粟米、五穀米、全麥麵粉等；要注意烹調時間越長GI值亦越高，食物越軟爛，消化時間就越短，血糖會升得較快。

Get to know low GI foods
“I was recently diagnosed with diabetes, and the doctor asked me to take note of the Glycemic Index of the foods I eat. Does that mean I have to start taking sugar-free foods?”
CheckCheckCin: Glycemic Index (GI) is used to measure the effects of carbohydrates (sugars and starches) on blood sugar levels. Once the carbohydrates enter the digestive tract, they will be broken down into glucose that can enter the bloodstream, causing an increase in the blood sugar levels.
Different foods will convert to glucose at different rates. Foods with higher GI can be digested and turned into glucose more easily. They are normally lower in fiber, high in refined carbs, and are easily mashed. These include rice, porridge, bread, cake, pumpkin, mashed potato, fruit juice, and sugar. They might cause blood sugar levels to spike.
On the contrary, foods with a lower GI have lower refined carbs and rich in fiber and protein. Some examples are brown rice, oats, whole wheat bread, spaghetti, apple, corn, white lentils, kidney bean, milk, and cheese. These foods can keep us full for a longer period. Hence, they are effective in controlling our blood sugar levels.
From the perspective of Chinese Medicine, foods with lower GI are generally coarse grains, and Chinese medicine practitioner recommend consuming them on a regular basis. These includes all types of whole grains such as oat, quinoa, buckwheat, millet, corn, grain rice, and whole-wheat flour.
Do note that the longer you cook these foods, the higher the GI readings you will get, as they become mashed. This will also shorten the digestion time, causing the blood sugar levels to rise.

五穀米gi值 在 [問題] 五穀雜糧中GI值較低又耐餓的主食?? - 看板BeautyBody 的推薦與評價
之前減重的飲食方針 是以蛋白質為主 並且稍微控制一下澱粉類的攝取...
最近對於平衡代謝飲食法及低GI飲食法有點興趣...
所以想把平常所吃的一部分高GI的澱粉類 轉換成低GI的澱粉類...
可是看到GI值的表中 常吃的五穀雜糧GI值幾乎都很高...
比較低的大概就 冬粉 米粉 玉米 綠豆 芋頭 這些...
在這些食物中 雖然冬粉的GI值最低 但很快就餓了 吃太多又怕總熱量超過...
米粉的GI值次低 多吃會傷胃 但飽足感還是比不上白米飯...
而玉米 綠豆 芋頭 三者GI值差不多 但只有比白米飯的GI值少10%左右 看來沒甚麼差...
由於冬粉跟米粉是加工製品 雖然號稱GI值低 可食在不怎麼安心...
想來想去 大概只有 玉米 綠豆 芋頭 這三樣可以選擇 實在很傷腦筋...
不知道版友們能不能推薦 低GI又可當主食的五穀雜糧 給小弟參考...
謝謝...

為降低罹患心血管疾病的風險 所以想把高GI澱粉 換成低GI澱粉...
像糯米 那破表的GI值 已經被我列入飲食的黑名單...
況且 我要找的是 飽足感堪比白米飯 然後GI值低的澱粉食物...
我是有想過糙米 但有實行上的困難...

不過沖泡燕麥片有個缺點 就是總熱量很高 稍微多吃一點 熱量就會不小心吃太多...
對了 剛看到還有一種東西的GI值也很低 比冬粉還低 就是"山藥"...
印象中 山藥好像很貴說 太常吃 可是傷荷包啊!!!
