The Nutritional Case
A tomato picked ripe from a farm and eaten the same day is nutritionally unrecognisable from a tomato picked green, gas-ripened in transit, and bought three weeks later. Studies show that some vegetables lose up to 45% of their vitamin C within a week of harvest, and up to 15% of their antioxidant content within three days.
Seasonal produce, eaten close to harvest, is at its nutritional peak. A mango in May is a genuinely different food from a mango in December — not just in taste but in phytonutrient content, enzyme activity, and mineral density.
The Body Wisdom Argument
Traditional Indian food systems were profoundly seasonal by necessity — and this produced remarkable alignment between what grew and what the body needed:
- Monsoon (June–September): Light, easily digestible foods — leafy greens, moong dal — because digestion weakens in humidity
- Winter (November–February): Root vegetables, jaggery, sesame, ghee — warming, calorie-dense foods for cold weather energy requirements
- Summer (March–May): Cooling foods — raw mango, cucumber, buttermilk, kokum — to regulate body temperature
The Environmental Case
Out-of-season produce requires either energy-intensive greenhouse growing or refrigerated long-haul shipping. A strawberry grown in a heated Dutch greenhouse in December has a carbon footprint 10–20 times higher than one grown seasonally in Mahabaleshwar in February.
Seasonal eating is the single most effective dietary change you can make for reducing your food carbon footprint — more impactful, calorie for calorie, than going vegetarian.
The best indicator of seasonal produce? Price and flavour. When something is cheap and extraordinary, it is in season. When it is expensive and mediocre, it has been shipped a long way.
Practical Tips
- Sign up for a weekly farm box — let the season decide your meals, not the other way around
- Learn to preserve: pickling, fermenting, and sun-drying extend the season's best produce
- Cook with the "ugly" seasonal surplus — misshapen carrots and split tomatoes taste identical to perfect ones and cost less
