Conn. AG launches investigation of Enviga calorie-burning claims

<p>Connecticut Attorney General Richard Blumenthal on Monday announced an investigation into claims by Coca-Cola and Nestle that their new drink can burn calories.</p><p>Blumenthal's investigation focuses on Enviga, a green-tea drink that contains caffeine, calcium and a green tea extract known as epigallocatechin gallate, or EGCG. Coke says EGCG speeds up metabolism and increases energy use, especially when combined with caffeine.</p><p>An Enviga Web site claims that the drink's blend of green tea and caffeine burns more calories than it contains and can help drinkers maintain an ideal weight. According to a Nestle study, young people who drank three of the 12-ounce beverages a day burned an average of 106 calories.</p><p>Blumenthal said he's demanded copies of all scientific studies, clinical trials, tests and papers that prove the calorie-burning claim by next week.</p><p>"Promise of wondrous weight loss must be supported by science, not magic," he said.</p><p>Calls were placed to Coke and Nestle seeking comment.</p><p>A nonprofit watchdog group, Center for Science in the Public Interest, have threatened to sue Coke and Nestle over their Enviga claims. Coke officials called the lawsuit threat a "meritless publicity stunt."</p>
