The latest World Health Organization data indicates that 1.9 billion people worldwide are overweight, with 600 million considered obese. Sugar, in the form of processed, high-in-sugar foods are largely to blame. Scientists around the world are making a desperate plea to stop an epidemic of obesity. But now, new research goes beyond fat to reveal a risk that could be even greater. TechKnow explores the science of sugar at the Department of Molecular Bioscience School at the University of California-Davis where cutting-edge research is being done. The project, headed by Dr Kimber Stanhope, put healthy young adults in their 20s on a highly controlled sugary diet for 10 weeks and then measured the effects of that added sugar. TechKnow explores the correlation between sugar intake and heart disease in young adults.
