What is a good way to reduce food waste?

Correct answer: Taking only as much food as needed

The governing concept is responsible consumption and waste prevention. Taking only the amount of food one is likely to eat prevents avoidable leftovers from being discarded. A practical approach is to begin with a modest serving and take more later if still hungry. Planning purchases, storing food correctly, checking use-by guidance, and safely reusing suitable leftovers can also reduce waste. Option C is the best answer because it prevents waste at the point of serving. Leaving extra food on the plate, putting edible leftovers in the dustbin, or intentionally allowing food to spoil all increase waste rather than reduce it. Food safety must always guide the handling of leftovers.
