Ayurveda emphasizes digestive strength (Agni) and proper food combining to maximize nutrient absorption. Key principles:
1. Eat According to Your Dosha
- Vata (Air/Ether): Warm, moist, grounding foods (e.g., soups, stews)
- Pitta (Fire/Water): Cooling, hydrating foods (e.g., coconut, cucumber)

2. Proper Food Combining
- Avoid: Mixing dairy with sour fruits (e.g., yogurt + berries)
- Good Pairings: Grains + legumes (e.g., rice + dal)
3. Enhance Digestion with Spices
- Turmeric: Boosts nutrient absorption
- Cumin & Fennel: Aid digestion
- Ginger: Stimulates digestive enzymes
4. Eat Fresh & Seasonal
- Freshly cooked meals retain more nutrients than processed foods.
- Seasonal fruits/vegetables align with the body’s needs.
