**TOPIC: 🍊 ORANGE (संतरा) — COMPLETE ROADMAP** Create one clean, professional roadmap diagram with connected boxes and arrows. **1. BASIC INTRODUCTION** * Fruit type: Citrus * Taste: Sweet and sour * Main nutrients: Vitamin C, water, fiber **2. NUTRITION & BENEFITS** * **Vitamin C** → Immune system support * **Fiber** → Digestion support * **Water** → Hydration * **Vitamin C** → Helps absorb iron from plant foods **3. HOW TO EAT** * Eat as a whole fruit * Best portion: 1 medium orange, according to individual needs * Pair with iron-rich foods for better iron absorption **4. CONS / CAUTIONS** * **Acidity** → May worsen acid reflux in some people * **Allergy** → Avoid if allergic to citrus * **Juice** → Less fiber and easier to consume excess sugar than whole fruit * **Dental health** → Frequent acidic exposure may affect tooth enamel **5. PROS** * Rich in vitamin C * Supports normal immune function * Provides fiber and hydration * Easy, convenient snack **6. FINAL VERDICT** **Orange = Vitamin C + Fiber + Hydration** Create one connected roadmap: INTRODUCTION → NUTRIENTS → BENEFITS → HOW TO EAT → CONS → FINAL VERDICT. Design: white background, orange-colored headings, simple icons, bold keywords, short text, readable boxes, clear arrows. Fit everything into one infographic.
