Our parents invented some pretty wild stories to prevent us from swallowing things we weren’t supposed to. Now that we’re older (and wiser), we know watermelon seeds won’t actually sprout a tree in our stomach. But what about the tales of gum sticking around in our digestive tract for years?
So where does the myth come from? Possibly from a real but rare phenomenon called a bezoar, a mass of undigested matter stuck in your stomach or intestines. If your cat hacks up hairballs, you know what I’m talking about. There is such a thing as a “chewing gum bezoar,” but it’s so rare that there have only been three cases reported in the medical literature—ever. Still – properly dispose of your gum, but that’s because swallowing it is gross, not because it’s unsafe.
A myriad of low-carb products are marketed as having “zero net carbs”, but a closer look at the nutrition label reveals most of the “cancelled” carbs to be from dietary fiber or sugar alcohols. What does this wizardry mean for calorie and carbohydrate counters? Not as much as the marketing would have you believe.
Net carbs is vastly more important to read that total carbs. The tortillas I buy are about 22g carbs, 6 net carbs. Eating two or three makes all the difference between having an elevated blood sugar, or up 100 points for a few hours.
