A new study in the American Heart Association journal Hypertension reports that consumption of one sugar-sweetened beverage (SSB) per day increased the systolic/diastolic blood pressure among study subjects (N=2,696) on average by +1.1 mm Hg/+0.4 mm Hg. The researchers conclude that SSBs are directly associated with blood pressure. We conclude that this study is meaningless.
Even accepting the study results at face value, they are of no clinical significance. The average BP in the one-SSB-per-day-group was 119.5/74.0 — under the ideal BP of 120/80. In the more-than-one-SSB-per-day group, mean BP was 122.5/75.5 — again, perfectly normal. Moreover, the study did not link SSB consumption with any clinical health effects.
You’ve heard of Coke Zero; this study is Hypertension Zero.
