While the food stuff is not renowned for its health benefits, popcorn could help improve the hearts of individuals.
This is according to Catherine Collins, chief dietician at St George's hospital in London, who noted that the snack contains important nutrients.
She said: "Most people don't know that popcorn is a wholegrain shown to reduce the risk of heart disease and cancer."
The expert went on to claim that a 30g serving of the food, which is equivalent to half a small box in the cinema, amounts to one daily portion of brown rice or wholewheat pasta.
Other things identified by Collins as having benefits to health were peanut butter - which is rich in monounsaturated fats - and baked beans, which are high in protein, fibre, iron and calcium.
Meanwhile, Katherine Jenna, nutritionist at the Consensus Action on Salt and Health, recently suggested that salt labelling on food needs to be improved so people can make more informed choices.
