Dr. Richard Johnson cautions consumers on the dangers of indulging in too many sugars, especially fructose. Fructose is a simple sugar that is found in fruit and vegetables.
Dr. Johnson is the chief of the division of kidney disease and hypertension at the University of Colorado. He is also the author of a book on the downside of fructose, called "The Sugar Fix".
Fructose from whole fruit and vegetables may be less damaging than fructose from added sugars. However, Dr. Johnson strongly recommends that you be careful about how much you consume in the way of fruit and vegetables. Fructose in fruit juice can present even more of a hazard to your health.
Though it appears that some of us are more vulnerable to the effects of fructose than others, Dr. Johnson advises all of us to use moderation where fructos is concerned.
Fructose appears to have a detrimental effect on the body's uric acid levels. And uric acid levels that are too high can cause some real and ongoing damage. Too much fructose may cause diabetes, hypertension and obesity.
