A new research has found that some popular popcorn brands have quite high amount of salt and sugar. During their assessment, Consensus Action on Salt & Health (CASH) has found popcorns to be having around 30 teaspoons of sugar.

The campaign group has criticized the food industry of 'disguising highly processed snacks like popcorn with a healthy halo'. It has also asked companies to bring a decline in the levels of salt and sugar in their popcorn.

For the survey, salt content of 154 flavored popcorn products sold in big supermarkets, safes and cinemas were assessed. One in four was found to be having extremely high levels of salt. Out of all, the campaign group officials have found cinema chains to be the biggest offenders. As much as 3.7g of salt per pack and My Vue's large salted popcorn had 3.1g of salt per pack.

Coming to the saltiest supermarket popcorn in the market, popcorn Kitchen's Sea Salt & Olive Oil had 3.5 g of salt per 100g and Metcalfe's Skinny Popcorn White Cheese, which had 3.45g of salt per 100g.

Other products having high level of salt were Metcalfe's Skinny Topcorn Wasabi Glaze; McEnnedy Microwave Popcorn Butter Flavour from Lidl; Metcalfe's Skinny Popcorn White Cheese and Pret A Manger Rock Salt Popcorn.

Sweetest popcorn included Morrisons Toffee Popcorn; Asda Chosen by You Toffee Popcorn and Aldi's Popcorn Toffee. "Popcorn has reinvented itself as a healthy and flavoursome snack but not all brands are delivering on this
- with certain products containing dangerously high levels of salt and sugars", said CASH nutritionist Sonia Pombo.
