Popcorn is actually a superfood. Super low calorie, it is also anti carconogenic and just 30g - that's half a small box of popcorn in the cinema - is equivalent to one daily portion of brown rice or wholewheat pasta. Popcorn also contains three times more fibre by weight than sunflower seeds, as well as balancing your blood sugar levels and helping to lower cholesterol. It even has a dose of B vitamins to boost your energy levels. Rad.
So eat up!
