People baffled by health messages

People know a healthy lifestyle is important, but most are still baffled by guidelines on fruit, exercise and alcohol, a report shows. Most adults knew they should eat five portions of fruit or veg a day, but few knew what constituted a portion, the Health Survey for England found. Over two thirds did not know or under-estimated how much exercise to do. And less than a third of adults knew the maximum amount of alcohol they should be drinking each day. - BBC
