Enjoying an iced coffee? Better skip dinner or hit the gym afterwards, with a cancer charity warning that some iced coffees contain as many calories as a hot dinner.
   The World Cancer Research Fund conducted a survey of iced coffees sold by some popular chains in Britain including Starbucks, Coffee Nero and Costa Coffee to gauge the calories as studies increasingly link obesity with cancer.
   The worst offender — a coffee from Starbucks — had 561 calories. Other iced coffees contained more than 450 calories and the majority had in excess of 200.
   Health experts advise that the average woman should consume about 2, 000 calories a day and a man about 2, 500 calories to maintain a healthy weight. Dieters aim for 1, 000 to 1, 500 calories a day.
   "The fact that there is an iced coffee on the market with over a quarter of a woman’s daily calories allowance is alarming. " Dr Rachel Thompson, science programme manager at London-based WCRF, said in a widely-reported statement. "This is the amount of calories you might expect to have in an evening meal, not in a drink. "
   The WCRF has estimated that 19, 000 cancers a year in Britain could be prevented if people lost their excess weight with growing evidence that excess body fat increases the risk of various cancers.
   "If you are having these types of coffee regularly then they will increase the chances of you becoming overweight, which in turn increases your risk of developing cancer, as well as other diseases such as heart disease, " she added.
