Can Diabetics Eat Popcorn?

Tight on a 45 g meal

18.6g carbohydrate per 3 cups air-popped (24 g)

One serving is 41% of a 45 g carbohydrate budget — most of the meal.

Recalculates as you change it.

18.6 g of carbohydrate per serving against a 45 g per-meal budget — 41% of the meal. We call it a fit at a third of the budget or less, tight up to two thirds, and over above that.

Why

Air-popped, the carbohydrate is moderate and the fibre is real. Microwave and cinema popcorn are the same kernel with a great deal of fat and salt added.

Popcorn is a whole grain, and three cups is a genuinely large-looking snack for 15 g of net carbohydrate — the volume-to-carbohydrate ratio is what makes it useful. The catch is that almost nobody eats it air-popped. A medium cinema serving is several times this portion with oil and salt on it, and that is a different food entirely.
