Great question — it's about understanding which cooking methods preserve nutrients best, because that's something you control. The short answer: vegetables with harder cell walls and shorter cook times lose fewer nutrients. Carrots, Brussels sprouts, and broccoli hold up well to roasting or quick sautéing. Leafy greens like spinach and kale actually release some nutrients when heated (like lycopene becomes more available), but they're fragile, so a quick sauté beats a long simmer. The principle: heat, water, and time are the enemies of water-soluble vitamins (like B and C). So roasting, stir-frying, or steaming for a short time beats boiling for 20 minutes. If you do boil (say, for potatoes), use that cooking water in soup or stock — the nutrients went into the water, not away. The real win? Cook vegetables in a way that makes you actually eat more of them. A roasted broccoli you love beats a perfectly preserved one you skip. What cooking method do you usually reach for with your favorite vegetables?
