Soft Drink - Health Effects

Health Effects

The consumption of sugar-sweetened soft drinks is associated with obesity, type 2 diabetes, dental caries, and low nutrient levels. Experimental studies tend to support a causal role for sugar-sweetened soft drinks in these ailments, though this is challenged by other researchers. "Sugar-sweetened" includes drinks that use high-fructose corn syrup, as well as those using sucrose.

Many soft drinks contain ingredients that are themselves sources of concern: caffeine is linked to anxiety and sleep disruption when consumed in excess, and some critics question the health effects of added sugars and artificial sweeteners. Sodium benzoate has been investigated by researchers at University of Sheffield as a possible cause of DNA damage and hyperactivity. Other substances have negative health effects, but are present in such small quantities that they are unlikely to pose any substantial health risk provided that the beverages are consumed only in moderation.

In 1998, the Center for Science in the Public Interest published a report titled Liquid Candy: How Soft Drinks are Harming Americans' Health. The report examined statistics relating to the increase in soft drink consumption and claimed that consumption is "likely contributing to health problems." It also criticized marketing efforts by soft drink companies.
