A sweetened beverage is any beverage with added sugar. They have been described as "liquid candy." Consumption of sweetened beverages has been linked to weight gain, obesity, and associated health risks.
Non-nutritive sweeteners (NNSs) have been introduced into the market in non-caloric drinks such as diet sodas. These artificial sweeteners are popular due to the growing demand for alternatives to sugar-sweetened beverages (SSBs). These sweeteners are more potent than regular, natural sugars. NNSs have shown to help short-term weight loss initiatives, but they don't show significance in the long-term. Recent studies have been conducted to see whether or not NNSs pose a great risk for the development of certain diseases. One such study researched the effect of NNSs with cardiovascular disease. The research was taken using post menopausal women. Women who consumed two or more diet drinks (containing NNSs) were found to be 30% at risk for cardiovascular disease. There has been a decline in liquid calories due to the introduction of NNSs.
A number of studies suggest that there is a significant correlation between increased consumption of sweetened beverages and weight gain leading to obesity. There has also been an association between consumption of sweetened beverages and health risks such as coronary heart disease and diabetes. Due to negative health effects of overconsumption of sweetened beverages, a sweetened beverage tax (soda tax) has been recommended by the Institute of Medicine in 2009.
Some countries have tried to reduce sugary beverages in an effort to bring liquid caloric intake down. Mexico placed a tax on SSBs in 2014. Drinks that were not taxed included drinks with NNSs, milk with no added sugar, and water. Other governments are active in placing policy on school lunches or what is being offered in school cafeterias in regards to beverages. Governmental activity is trying to eventually slow down the obesity epidemic.
