Hard seltzer? Coming from a dietician's perspective, it is a hard sell.
While various brands of hard seltzer (and still water!), From White Claw to Truly, have emerged over the past few years, a news flooded last week: Four Loko. Specifically, Four Loko Sour, a hard harness that boasts a volume percent alcohol (14V). This is equivalent to almost three macro brews and about the equivalent of a glass of wine.
But is it any healthier?
First, it's much easier to drink a seltzer than to sip a glass of wine or even a beer, which means More calories (and more booze) go down your gut faster.
You think that seltzer is lighter and that it keeps you hydrated better than beer or wine. In fact, many hard seltzer companies are leading this to believe. But that's just now how the body works. Alcohol, whatever it is paired with, dehydrates you. Period. There is no health glory around it.
Speaking of calories, I would estimate that this particular brand of Four Loko seltzer, given its ABV, probably has at least 400 calories per 12 ounce can.
