The newest addition to the Starbucks menu (NASDAQ: SBUX), the mini Frappucino, is the smallest member of the sugary-Starbucks Frappucino family. However, despite its smallness, dieticians still warn the beverage is more of a dessert than a beverage or cup of coffee. "When they have a bigger size, they eat and drink more and don't realize it," dietitian Katherine Tallmadge said, according to The Huffington Post. "And people report that when they have a smaller size, they're completely satisfied. Currently, a tall coffee flavored mini Frappucino has 24 grams of sugar with 120 calories; a tall, the next largest size, has 36 grams of sugar and 180 calories, HuffPost reported. "I think it's great news" that Starbucks is offering a smaller size, said Katherine Tallmadge, a registered dietitian and op-ed contributor to Live Science. "It's a good idea for all of the food companies to think about smaller sizes," Tallmadge said. For more business and financial news, click here.
