Let’s be honest: your biggest nutrient threat isn’t the microwave. It’s the ultra-processed snacks and late-night takeout you’re probably microwaving. A microwaved sweet potato with black beans is a feast of fiber and vitamin A. A microwaved frozen pizza? Less so.
So don’t demonize the machine. Focus on the food itself. If you’re warming up a veggie-packed stir-fry, you’re doing just fine. Your body won’t know it was reheated—it will just absorb the goodness.
