Hi Fit,
I have been keeping a food journal as part of my weigh loss efforts, and have been tracking what I eat, portions, and nutritional balance. However, there is one thing that I am lost about: sugar intake. Every day I look through what I've eaten and see what I need to eat more of and eat less of, but the problem is I have no idea what the normal healthy range of sugar is. Most of the sugars I eat come from healthy sources such as fruits, but sometimes I will have processed sugars as well. Thanks.

I think it is great that you are tracking what you eat since keeping a food journal [1] has been proven to help dieters. To see what I have to say about daily sugar intake, .

There currently is no officially sanctioned recommended daily allowance for sugar [2]. However, the US Department of Agriculture, the government agency behind the food pyramid, suggests that added sugars should make up only six to 10 percent of your daily calories. Based on a 2,000 calorie diet, that adds up to between 30 and 50 grams of added, not naturally occurring, sugars.

Sugars are a simple form of carbohydrates, so you can also monitor your sugar intake by limiting added sugars to 10 percent [3]of your overall carb consumption. If you eat 300 grams of carbs in a day, then you should keep added sugars to 30 grams. That is about 1/8 cup [4], to give you a visual on size.

Unfortunately, current nutrition labels lump all sugars, like sucrose (table sugar) and fructose (fruit sugars), together. For example, lactose, a sugar that occurs naturally in milk, will be added into the total grams of sugar of a flavored yogurt with added sugar or sweetener. If you steer clear of processed foods, often loaded with added sugar in the form of high fructose corn syrup [5], and avoid adding sugar to your coffee, cereal, and sliced fruit, you should be fine.
