The USA and UK are worried about how bad sugar is for public health. People eat too much sugar. This is harmful to people's health. The USA made new diet guidelines. They recommend people get less than 10 per cent of their calories from sugar. Britain's leader said he was thinking about a tax on sugar. Politicians in the UK are talking about how less sugar in food could lower rates of obesity in Britain.

Both governments looked at a study from Mexico. It showed how a tax on sugary drinks meant sales of sugary drinks went down by 12 per cent. Sales of mineral water went up by four per cent. Another idea is to reduce the level of sugar in drinks. A London university said that cutting the sugar in drinks by 40 per cent over five years could prevent one million cases of obesity in the U.K. The researchers say people might not even notice this.
