The Harm of Added Sugar
Is sugar always bad? Not necessarily. Many healthy foods contain naturally-occurring sugar, including fruits, some vegetables, milk, and whole-grain foods. Sugar is recognized by the FDA as a nutrient. The problems start when you consider how much sugar is found in the average Western diet. When you eat too much added sugar (and most Americans do), it becomes difficult to include enough fiber, vitamins, and other essential nutrients to your diet while retaining a healthy weight.
If you look at the nutrition labels of your favorite foods, you can find how many grams of sugar are lie within. But currently you cannot tell whether that sugar comes from a natural source such as dried fruit, or if it has been sneaked in with the rest of the ingredients later. This will change in 2020 when new nutrition labels will be required, but for now, you have to read the ingredients list carefully. In general, you should choose foods that have added sugar sources like cane sugar, honey, dextrose, and high fructose corn syrup low on the ingredient list.
