Give up chocolate to help BHF Emma Day, head of Dechox, British Heart Foundation, writes: This March, the British Heart Foundation (BHF) is encouraging the British public to take on their Dechox challenge and give up chocolate and other sugary snacks for the month of March. Dechox Warriors will help to raise life saving funds for the 7.6 million people in the UK living with heart and circulatory diseases. A recent survey carried out by the BHF, revealed that biscuits were the UK’s favourite sugary snack (42 per cent), closely followed by chocolate (41pc). With the findings demonstrating just how important biscuits and chocolate are to us, giving them up will be no easy feat.
