In a new study on sugar, mostly coming from beverages, apparently a 24 oz. Jamba Juice smoothie has more than 70 grams of sugar in it. Instead, if you order a smoothie, ask for whole fruit, no added juices, and greek yogurt if possible. Speaking of yogurt, another culprit is flavored yogurt. Not only is it high in sugar, their added preservatives and high fructose corn syrup. Instead, go to yet again greek yogurt.
The American Heart Association recommends men limit added sugar to 36 g, or 9 tsp., per day and that women limit added sugar to 24 g, or 6 tsp., per day.
So the moral is to ask for what you'd make at home, if possible. If we do more of this, we speak volumes that we want our food healthier. Unhealthy does not = tasty.
