I saw on this keto granola my dad bought where it said carbs minus sugar alcohols equals net carbs. That made me kind of curious about it. And if this is really true then what if I drank a Diet Pepsi and ate some rice? Would it make the rice have no carbs?
Sugar alcohols are carbs, just like fibre. And like when you are calculating net carbs of a product, you subtract the grams of fibre, it is the same for sugar alcohols. However, they do not cancel out other carbs like your Diet Pepsi and rice scenario.
