Some food has more fat, sugar or salt(盐). Most people, especially(特别是) kids, like these kinds of food, and they like drinking sugary(含糖的) drinks. That' s why there are lots of fat people now.
To make people keep healthy, the UK will stop the " buy one get one free" sale if they want to buy some unhealthy food. It will stop free refills(免费续杯) of sugary drinks in restaurants. These rules will start in April, 2022.
The government says being fat is one of Britain' s biggest public health problems. About two-thirds of adults in England are overweight(超重的) and one in three children are overweight or get fat.
The UK also makes other rules. People can' t have big sales of unhealthy food at checkouts(付款台), shop entrances or at the end of aisles(过道). The government will restrict(限制) the advertise-ments(广告) of the big sales of unhealthy food in the shop.
