One reason to avoid daily sodas:
From the June 2015 Nutrition Action Review: "In just two weeks, even modest doses of high-fructose corn syrup (HFCS) raise LDL ("bad") blood cholesterol and other risk factors for heart disease and gout." A study on 85 adults found that the more HFCS they drank, the "higher their LDL cholesterol, after-meal tri-glycerides, and average uric acid levels." The article also reminds readers that while this study used HFCS, table sugar has roughly the same amounts of fructose and glucose.
The article in Nutrition Action Review summarizes a study found in Am. J. CLin. Nutr. 2015. doi:10:3945/ajcn.114.100461.
