Many doctors treat soda, sweetened iced tea, bottled fruit drinks and energy drinks as the first thing to leave behind, not because they are dramatic, but because they are so easy to overconsume. Studies say frequent sugary-drink intake is linked with negative health consequences, and its guidance on “rethink your drink” ties regular consumption to weight gain, type 2 diabetes, heart disease, cavities and gout. The American Heart Association also notes that sugar-sweetened beverages are a major source of added sugar.
