糖尿病の食事ガイド：低GI食品リスト

低GI食品は食後血糖の上昇をゆるやかにしやすい食品です。しかし実際の食事では、GI値だけでなく炭水化物量、分量、調理法、薬のタイミング、自分の測定結果を合わせて見る必要があります。

Low GI foods

選びやすい食品はオートミール、大麦、レンズ豆、ひよこ豆、黒豆、固めにゆでた全粒パスタ、少量の玄米や雑穀、無糖ヨーグルト、りんご、梨、ベリー、葉物、ブロッコリー、きのこ、豆腐、卵、魚です。

Foods to limit

白パン、甘いシリアル、やわらかい粥、マッシュポテト、甘い飲料、果汁、菓子は注意が必要です。完全禁止より、量を小さくし、野菜とたんぱく質を先に食べる方法が続けやすいです。

Plate method

実践では皿の半分を非でんぷん野菜、四分の一をたんぱく質、四分の一を低GI炭水化物にします。食後一から二時間の記録を比べると、自分に合う量を見つけやすくなります。

Shopping checklist

Choose unsweetened products, intact grains, beans, vegetables, and clear serving sizes. Keep protein and vegetables ready so the easiest meal is also balanced. Low GI does not mean unlimited, low calorie, or automatically low carbohydrate. Compare your own readings and clinician targets before making strict rules.

FAQ

Is every low GI food safe without limits?

No. Portion size, total carbohydrate, activity, medication, and individual glucose response still matter.

Can fruit fit?

Whole fruit in a planned portion often fits better than juice or dried fruit.

When should response be checked?

Follow your care plan. Many people compare readings one to two hours after the start of a meal, but targets should be set with a clinician.
