Thumbs up: The British National Consumer Council (NCC) has called for the introduction of a colour-coded rating system for televisions, DVD players, games consoles and laptops, similar to that used on refrigerators and washing machines.

McDonald's plans to launch a petition calling for the term to be changed.

For men, the risk of high blood pressure does not significantly increase or decrease, regardless of how much coffee they drink.
