The diamond poem, which is also called a diamante, is a relatively new form of poetry. Many credit Iris Tiedt with its development in the late 1960s.
The confusion may arise because of research that found a connection between carbonated cola drinks and low bone mineral density.. While artificially carbonated water is slightly more acidic than still water, it's not as acidic as sugary sodas, and does not seem to significantly damage tooth enamel.
Still, there are worse things, health-wise, than a can of raspberry-lime Polar seltzer. While the acidity level of a flavored seltzer is on par with soda and juice, the calorie and sugar contents tend to be far lower. Brands like Polar and LaCroix are calorie-free, whereas a can of Coke contains 140 calories.
