Popcorn is a whole grain. Unlike refined grains that manufacturers have processed to remove the bran and germ, whole grains include the entire grain seed, also called the kernel.

It is also high in fiber, and high-fiber whole grains can reduce the risk of conditions such as:

The fiber in popcorn can also improve digestion and help people to feel full for longer.

Air-popped unflavored popcorn is low in calories and fat. It is also high in fiber. This means that consuming it as part of a balanced diet may aid in weight loss or weight maintenance.

However, added butter, sugar, and salt can add a lot of calories and sugar. This means that it is best to consume popcorn without any toppings if a person is focusing on losing or maintaining weight.

When consuming it in moderation, popcorn may be suitable for people with diabetes.

Air-popped, unsweetened, unsalted popcorn has a glycemic index (GI) score of 55. This means that it is a medium GI food, which refers to foods with a GI rating of 55 to 69.

GI is important for people with diabetes as it indicates how quickly a food that contains carbohydrates will raise blood sugar levels. A medium GI food will raise levels more slowly than a high GI food but more quickly than a low GI food.

Adding sugary toppings or other flavours to popcorn may affect its suitability for people with diabetes.

Air-popping means heating the hard popcorn seeds, or kernels, in hot air until they burst and become popcorn.

People can add oil or butter for flavoring, but the popcorn does not need any oil to pop. If someone wants to add oil, they can use a version that contains healthful polyunsaturated fats, such as avocado oil.

Use the following recipe to air-pop the popcorn kernels:

  1. Heat a large pan and add the popcorn kernels, then put the lid on.
  2. Gently shake the pan regularly.
  3. Listen out for the kernels popping, which should take 1 or 2 minutes.
  4. Keep shaking the pan until the popping stops.
  5. Remove from the heat and serve.
