I think it's accurate for China. There's lot of veggies in dishes in China everywhere I've been. This is pre-cooked weight certainly. I'm in the US and definitely more vegetarian than average but each week I go through a head of broccoli, 500g-1kg of bok choy or gailan, mandolin + pre-prep 6 large onions (>2.2kg) & 10-12 bell peppers (usually ~1.5kg), a couple 250-300g sweet potatoes, and 3-4x384g bags of frozen spinach.
