+- ❌ **Low contrast text** — Maintain 4.5:1 minimum contrast ratio
+- ❌ **Instant state changes** — Always use transitions (150-300ms)
+- ❌ **Invisible focus states** — Focus states must be visible for a11y
+
+---
+
+## Pre-Delivery Checklist
+
+Before delivering any UI code, verify:
+
+- [ ] No emojis used as icons (use SVG instead)
+- [ ] All icons from consistent icon set (Heroicons/Lucide)
+- [ ] `cursor-pointer` on all clickable elements
+- [ ] Hover states with smooth transitions (150-300ms)
+- [ ] Light mode: text contrast 4.5:1 minimum
+- [ ] Focus states visible for keyboard navigation
+- [ ] `prefers-reduced-motion` respected
+- [ ] Responsive: 375px, 768px, 1024px, 1440px
+- [ ] No content hidden behind fixed navbars
+- [ ] No horizontal scroll on mobile

+食物升糖指数（GI）是衡量食物引起餐后血糖反应的一项有效指标，它反映了人吃进食物后，在一定时间内血糖上升的速度和峰值。对于糖尿病患者而言，了解食物的升糖指数并据此安排饮食，对于控制血糖水平至关重要。
+一、升糖指数的分类
+根据升糖指数的高低，可以将食物分为以下几类：
+低升糖指数食物：GI值在55以下。这类食物在胃肠中停留时间长，吸收率低，葡萄糖释放缓慢，进入血液后的速度慢、峰值低。对于糖尿病患者而言，低升糖指数的食物有助于稳定血糖水平。常见的低升糖指数食物包括：
+五谷类：全蛋面、荞麦面、粉丝、黑米、黑米粥、通心粉、藕粉等。
+蔬菜类：魔芋、粟米、大白菜、黄瓜、芹菜、茄子、青椒、海带、金针菇、香菇、菠菜、番茄、豆芽、芦笋、花椰菜、洋葱、生菜等。
+豆类：黄豆、眉豆、鸡心豆、豆腐、豆角、绿豆、扁豆、四季豆等。
+水果类：苹果、水梨、橙子、桃、提子、沙田柚、雪梨、车厘子、柚子、草莓、樱桃、金桔、葡萄等（注意，某些水果如西瓜在不同成熟度下GI值可能有所不同，但一般来说，成熟度较低的西瓜GI值较低）。
+奶类：牛奶、低脂奶、脱脂奶、低脂乳酪、红茶、优格、无糖豆浆等。
+中等升糖指数食物：GI值在56~69之间。这类食物进入胃肠道后消化速度适中，葡萄糖释放入血液的速度也适中。糖尿病患者可以适量食用中等升糖指数的食物，但需注意控制摄入量。常见的中等升糖指数食物包括：
+主食类：红米饭、糙米饭、西米、乌冬面、面包、麦片、番薯、芋头等。
+蔬菜类：薯片、番茄、莲藕、牛蒡等（注意，这些蔬菜的GI值相对较高，但相比于高升糖指数食物仍属于中等水平）。
+肉类：鱼肉、鸡肉、鸭肉、猪肉、羊肉、牛肉、虾子、蟹等。
+水果类：木瓜、提子干、菠萝、香蕉、芒果、哈密瓜、奇异果、柳丁等（这些水果的GI值较高，但相比于纯糖类食物仍属于中等水平）。
+其他：蔗糖、蜂蜜、红酒、啤酒、可乐、咖啡等。
+高升糖指数食物：GI值在70及以上。这类食物进入胃肠道后消化快，吸收率高，葡萄糖释放入血液快，容易导致血糖水平急剧升高。糖尿病患者应尽量避免或限制高升糖指数食物的摄入。常见的高升糖指数食物包括：
+主食类：白饭、馒头、油条、糯米饭、白面包、燕麦片（需注意，不同品牌的燕麦片GI值可能有所不同，但一般来说，即食燕麦片的GI值较高）、拉面、炒饭、爆米花等。
+肉类加工品：贡丸、肥肠、蛋饺等。
+蔬菜类：薯蓉、南瓜、焗薯等（这些蔬菜的GI值非常高，应尽量避免食用）。
+水果类：西瓜（成熟度较高的西瓜GI值较高）、荔枝、龙眼、凤梨、枣等。
+其他：葡萄糖、砂糖、麦芽糖、汽水、柳橙汁、蜂蜜等。
+二、升糖指数的影响因素
+食物种类：不同种类的食物具有不同的升糖指数。例如，豆类食物的升糖指数通常低于谷类食物；大麦的升糖指数低于小麦；苹果的升糖指数低于菠萝等。
+膳食纤维含量：膳食纤维越多，食物的升糖指数越低。因此，富含膳食纤维的食物如全谷物、蔬菜、水果等通常具有较低的升糖指数。
+食物加工方式：食物的加工方式也会影响其升糖指数。例如，加工时间越长、温度越高，食物的升糖指数就越高。因此，糖尿病患者应尽量选择未加工或少加工的食物。
+食物成熟度：某些食物的成熟度也会影响其升糖指数。例如，成熟度较高的西瓜和香蕉等水果的升糖指数通常较高。
+三、建议
+对于糖尿病患者而言，了解食物的升糖指数并据此安排饮食是非常重要的。以下是一些建议：
+优先选择低升糖指数食物：在日常饮食中，应优先选择低升糖指数的食物，如全谷物、蔬菜、水果（注意选择成熟度较低的水果）、豆类等。
+适量摄入中等升糖指数食物：中等升糖指数的食物可以适量摄入，但需注意控制摄入量，避免血糖水平急剧升高。
+避免或限制高升糖指数食物：高升糖指数的食物应尽量避免或限制摄入，如白饭、馒头、油条等主食类以及含糖量高的水果和饮料等。
+注意食物搭配：在安排饮食时，应注意食物的搭配，使不同升糖指数的食物相互补充，以达到均衡营养的目的。
+定期监测血糖水平：糖尿病患者应定期监测血糖水平，以便及时调整饮食和治疗方案。

+食物升糖指数（GI）知识摘要（霍大夫），面向农村老人日常吃饭：
+- 低 GI（≤55）：小米、玉米碴、杂面、大部分蔬菜、豆腐、鸡蛋、苹果/梨/柚子等，有助于稳血糖。
+- 中 GI（56-69）：二米饭、红薯、土豆、香蕉等，可以吃但要少、别当顿顿主食。
+- 高 GI（≥70）：白馒头、白稀饭、油条、粘豆包、糯米饭、西瓜、含糖饮料、糕点，尽量别碰。
+- 午餐蛋白质要最高：鱼、鸡鸭、瘦肉、蛋、豆腐至少两样，午饭是全天蛋白主力。
+- 淀粉不重复：粥/饭/面/饼/薯/玉米/南瓜等，早中晚各最多一种，三顿不要同一种、别顿顿大主食。
+- 吃饭窍门：先吃菜和蛋白，再动主食，每餐七分饱。
