How many grams of sugars does a person need daily?
You don't need any sugar per se in your diet. Sugars are carbohydrates, of which 300g are recommended in a 2000 calorie diet -- but not all of your carbohydrates should be sugars! Only a fraction should be sugars, if any. Refined sugars are completely unneeded and provide only calories from a nutritional perspective -- they can be eliminated. So 0 grams of refined sugars are recommended in a day. Fruits contain a large amount of natural sugars, which are less rapidly absorbed. In addition, fruit offers a number of other nutritional benefits as well, so a portion of your 300g of carbohydrates should be sugars from fruit, since fruit should be included in one's diet. Instead of looking for a number, look to reduce empty sugars (such as high fructose corn syrup, granulated sugar, cane juice), while getting such sugars instead from nutritionally beneficial sources such as fruits and vegetables.
