1. Popcorn’s Ingredient: Whole Grain Corn
The popcorn we eat as a snack is a ‘whole grain’ food, made by heating whole corn kernels until they pop. This means that popcorn retains the rich dietary fiber and nutrients contained in the corn’s bran.
2. Popcorn vs. Potato Chips
When a person with diabetes craves a salty, crispy snack, they might debate between popcorn and potato chips.
– Cooking Method: Potato chips are thinly sliced potatoes ‘deep-fried in oil.’ In contrast, popcorn can be ‘air-popped’ without any oil.
– Nutritional Comparison (by volume):
– Calories and Fat: Air-popped popcorn is 3-4 times lower in calories and more than 10 times lower in fat than the same volume of potato chips.
– Dietary Fiber: As a whole grain, popcorn is rich in dietary fiber, which provides satiety and helps to moderate the speed of blood sugar rise.
– Glycemic Load (GL): Popcorn is voluminous, so for the same portion size, the total amount of carbohydrates consumed is less than with potato chips, resulting in a lower glycemic load.
3. ‘With Nothing Added’ is the Key
For popcorn to be a better choice than potato chips, the following conditions are essential:
– Cooking Method: It must be air-popped, not fried in oil.
– No Additives: You must not add toppings that increase calories, fat, sodium, or sugar, such as butter, caramel, salt, or cheese seasoning. Popcorn sold at movie theaters is the worst choice.
Summary: Pure, air-popped popcorn with no additives is a fiber-rich, whole-grain snack that is a much better choice for blood sugar and weight management than deep-fried potato chips.
