Britons are now opting for healthy food over junk diets, with preference for nuts, seeds and dried fruit instead of crisps and chocolate.
The trend for healthy eating has sent sales soaring to 547million pounds in 2009, market research analysts Mintel said.
A poll found 44 per cent - many over 45s - now buy cashews or other nuts as an alternative to crisps, reports The Daily Express.
Nuts are packed with omega-6, which boosts brainpower. And 36 per cent opt for dried fruit and not sweets.
"Consumers now want a nutritious snack," said Amy Lloyd, Mintel food and drink expert.
