Sure, soda can rot your teeth and make you fat, but that’s not all. Sugary drinks may increase your risk of heart disease, especially if you’re a heavy guy, say scientists from the University of California at Davis. In the study, overweight people who drank a fructose-sweetened beverage with a meal saw their triglyceride levels spike three times as high over 24 hours than people who drank a glucose-sweetened beverage. Triglycerides are fats in your blood, and high levels are thought to boost heart-disease risk. Your liver converts fructose to triglycerides, causing the spike, says study author Karen Teff, Ph.D. Most fruit juices also contains fructose, so dilute apple juice with equal parts water.

In 2006 her school started using SODIS to disinfect its contaminated tap water, placing bottles on the building’s corrugated metal roof. The result? Absenteeism due to diarrhea has dropped considerably, and examination scores soared. “Before we started SODIS, only ten to fifteen percent of the children passed the national sixth grade exams,” says Mhelela, “Now ninety to ninety - five percent of the students pass.”
