Tips

A bowl of popcorn weighs 20 g: count on 84 kcal. The 419 kcal per 100 g look alarming, but popcorn is extremely bulky. A large bowl remains a reasonable snack.

12.8 g of fibre: it is a wholegrain cereal. The whole kernel is puffed, bran included. Few snacks reach this level, and it is what explains its filling power.

Everything depends on what you add. The oil-popped, salted version rises to 477 kcal and 2.61 g of salt, and the caramel one to 421 kcal, with more than a third of its weight as sugars. Plain, it is a completely different food.

Make it yourself, in a saucepan or the microwave. Corn kernels, a lid, three minutes: it is ten times cheaper than ready-made bags, and you control the oil and salt.

Avoid microwave bags. They contain the oil and salt built in, sometimes artificial flavourings. A simple covered bowl does the same job with plain kernels.
