6. Fiber
Most people fall far short of the 20 to 38 grams of fiber recommended daily. Without proper fiber, however, you can easily become constipated or develop hemorrhoids. Consuming adequate fiber has been shown to reduce the risk of developing health conditions such as diabetes, heart disease and diverticulitis.
In fact, the American Diabetes Association includes lemons on their list of superfoods because of their high fiber content. In addition, the pectin fiber in lemons can help keep you from getting hungry and overeating.
