What are the disadvantages of blanching vegetables?

The main disadvantages of blanching vegetables are the loss of water-soluble nutrients (like Vitamin C and B vitamins) and flavor into the water, the added time and effort for an extra cooking step, potential texture changes, and in industrial settings, the environmental impact of water usage and wastewater.
