While I was writing the Essential Carbohydrate post, I got to thinking about another canard often bantied about in low carb circles. That being that our circulating blood glucose amounts to only about a teaspoon of sugar. Here's how that calculation goes:
Another way of looking at this is that for a normal person, a "glucose spike" to 125 mg/dL amounts to an increase in dissolved circulating glucose of perhaps 2g (85 mg/dL - 125 mg/dL) and a glucose intolerant person might see 10g dissolved glucose in circulation (200 mg/dL) following a meal. This small amount compared to the "large amounts" of carbohydrate in even a small serving of pasta or rice is often seized on by low carb advocates to foster carbophobia.
