HEALTH SCARE: SALT KILLS 40,000 A YEAR

Bread and breakfast cereal are among the foods with the highest salt contents

HIGH levels of salt added to everyday foods are killing tens of thousands of people in Britain.

Experts estimate that if people cut their intake of salt to just one teaspoonful a day, it would save at least 40,000 lives a year.

A report published today says many consumers are unable to calculate their intake due to labels that sometimes say “sodium” instead of “salt”.

This means few people realise that bread contributes the highest amount of salt to their diets, followed by processed meats and then breakfast cereals.

Heart experts have called for a fresh law to clear up what they describe as “a scandal”.

About 200,000 people die from cardioavascular disease in the UK each year, but the report says reducing salt intake could cut that by about a fifth, or 40,000. Graham MacGregor, professor of cardiovascular medicine at St George’s Hospital in London, has led a campaign to get salt levels down.

He said: “At the moment there is confusion over salt labelling, with some products using the term ‘sodium’ instead.

The latest study, published in the British Medical Journal online, says cutting salt intake from 10 grammes a day – about two teaspoons – to five would reduce global death rates from cardiovascular disease by three million a year.

The analysis is one of the most comprehensive reviews of the link between salt and heart disease and adds to a large body of evidence on the dangers of salt.

The World Health Organisation already recommends that all countries try to reduce salt intake to no more than five grammes.

Although the UK has set its a target of six grammes a day, it has still won respect for doing more than most other nations to reduce salt intake.

In recent years, food producers have been told to slash the amount they add to foods, which has led to a 10 per cent reduction in intake since 2000, saving 6,000 lives a year.

But salt intake still stands at 8.6 grammes, a figure that most health experts agree is too high and there are fears that poor labelling is preventing it falling more quickly.

2009年5月17日世界高血压日主题：Salt and High Blood Pressure：Two Silent Killers
2009年10月8日全国高血压日主题与世界高血压日主题相同：限盐与控制高血压

高血压是全球脑卒中、心脏病和肾脏病死亡的最大危险因素，而盐是升高血压的重要危险因素，减少盐的摄入量可降低人群血压水平。根据科学推算，实际上在每天食物的基础上，摄入3g食盐就基本上达到人体钠的需要，但由于人们的膳食习惯和口味的喜爱，盐的摄入远远超过3g的水平。

世界卫生组织建议每人每天摄入食盐不超过6克(推荐量＜5克)，但目前世界上许多人每天摄入的食盐超过１０克。吃盐过多会使血压升高，而高血压是导致中风和心血管疾病的一个重要原因。

英国乔治大学研究员格雷安.麦克格雷戈说：“盐是导致肥胖病的一种隐藏诱因。”研究人员称所有引起肥胖的食盐并非来自餐桌上的可摇式盐瓶，其80%来自加工好的食物，包括如面包、松饼、谷类食品等主食。
