In 2017, when Coke created an ad campaign using an animated virtual soccer player from a digital game called FIFA 17, it made us wonder: Are real athletes and team owners getting smart about the health risks of drinking sweetened beverages?
It seems not.
That same year, Major League Baseball announced a multi-year partnership, naming Coca-Cola as the “official soft drink of MLB.”
Well, a new study in the American Journal of Physiology shows just how harmful such endorsements are — not just to fans who fall for the sweet talk, but for athletes everywhere.
Researchers from the University of Buffalo looked at the effect of drinking a beverage with high fructose corn syrup and caffeine on the health of someone who is working or working out in a high-temperature environment (it could be an agricultural site, a playing field outdoors, the gym, or at work).
In four one-hour segments, the study's participants worked out, took breaks, and drank 16 or more ounces of the soft drink.
Participants who drank soft drinks had higher blood levels of creatinine and a lower glomerular filtration rate — both markers for acute kidney injury.
They also had elevated blood levels of vasopressin, which raises blood pressure, and were mildly dehydrated.
Prove you're smarter than MLB and say: “No way I'm fake-quenching my thirst with kidney-damaging colas.”
Water will do. And for extended workouts or hot weather jobs maybe try water with electrolytes like sodium, potassium, and calcium added.
