It’s okay if something isn’t for you!
That is, like, the definition of nutritional benefit.
Boba has ~14g per 100g, depending on the type.
Coca Cola has ~11g sugar per 100g.
In other words, ice cream has 1.8x more sugar content than boba and 2.3x more sugar content of Coca Cola.
If you’re concerned about the tapioca, that’s literally just starch. You know what else contains starch? Potatoes and rice.
Most Boba Tea cups I’ve seen are far bigger than the typical ice cream.
You can’t use per-100gm doses this way. You have to look at sugar in the product as ordered.
People don’t order and eat their food in neat 100gm increments.
Either way, a little 16oz carton of Ben and Jerry's that people smash in one sitting is 1200 calories. So it's still more sugar- and calorie-dense than boba tea.
I don't really see the point in bickering over calorie-dense junk foods though. Both of them are displacing healthier foods in your diet that you could've eaten instead. Neither should account for more than a small fraction of your calorie intake.
What did you expect me to do, bash out a 5x10 multi-company matrix so you can compare perfectly across servings?
Nothing at Boba Guys weighs 100g. That's the difference! 100g really is a typical cup of gelato or ice cream.
