Most of us know that salt raises blood pressure in many people. When I learned that in medical school almost 40 years ago, I have not touched a salt shaker since. I enjoy having a low normal blood pressure. A new study published in the Journal of the American Society of Nephrology (July 2010) suggests that sugar, especially the fructose that comes from corn syrup, may also raise blood pressure.
A study team from the University of Colorado in Denver looked at sugar intake among thousands of Americans in a major national nutrition survey between 2003 and 2006. Those who consumed more added sugars, such as the fructose in soft drinks, had significantly higher blood pressures than those who did not and ate more natural foods such as fresh fruit.

There also does not appear to be an easy solution – voluntary diets founded primarily on will power are notoriously ineffective in the long term. Add to that is the marketplace of misinformation that makes it challenging for the average person to even know where to apply their (largely ineffective) will power.

Food products that provide cheap calories and are tasty (sweet, fatty, or salty) sell well and provide market incentives to sell such products. Consumers then get spoiled by the cheap abundance of tempting foods, even to the point that our perspective on appropriate portion sizes have been super-sized. Read more »
