DIETICIANS are ringing alarm bells over the increasing size of energy drink cans, with one offering more kilojoules than a roast dinner.
Many of the well known brands, like V and Mother, are now available in half-litre cans. Rockstar Punched comes in 710-millilitre cans, even though its own warning label says you should consume no more than 500 millilitres of it in a single day.
A comparison of the cans shows that many have the equivalent caffeine of two to three cups of brewed coffee in them, but there is a huge difference in energy levels and that’s where they can make a big difference to the waistline. Many have more sugar per 100 millilitres than Coca-Cola. Rockstar packs 2024 kilojoules, equivalent to more than three cans of Coke.
