That means putting a health warning on the packet, not complex labels in small print that few of us can make sense of when we’re rushing down a supermarket aisle. I’d like to see a clear, unequivocal health warning on processed food and drink in a universal language: you simply show consumers the number of teaspoons of sugar each product contains. Governments have a moral and financial responsibility to tackle obesity. So although it may be slower than I would like, I do think the reckoning is coming for Big Food. Wise companies will shape up.
