What are two disadvantages of having a microwave cooker?

1. Uneven heating: Microwaves heat food by exciting water molecules, which can lead to uneven heating throughout the food. This can result in some parts of the food being overcooked while others are still undercooked.

2. Destruction of nutrients: Microwaves can also destroy nutrients in food, particularly vitamins and minerals. This is because microwaves generate heat which can break down these nutrients.
