Still confused over how much sugar is too much? The 2015-2020 U.S. Dietary Guidelines Committee has proposed Americans limit the amount of sugar they consume to no more than 10 percent of daily calories. For most people that's about 200 calories or 50 grams of sugar (about 12 teaspoons). The committee also discourages replacing sugar with low-calorie sweeteners.
Most Americans consume more than 200 calories of added sugars daily, mostly in the form of sugary drinks. One cola contains about 44 grams of sugar. A Starbucks grande latte has 17 grams of sugar, though this includes the natural sugars in the milk or cream.
While these proposed dietary limits may seem low, they are actually higher than the recommendations of the American Heart Association, which suggest women should eat no more than 100 calories in added sugars per day (about 25 grams), and men should limit intake to 150 calories (about 37 grams).
