Victoria Beckham reveals her kids' rather unusual after-school snack

Victoria Beckham is famous not just for her Spice Girl years, but for her svelte figure and super healthy diet.

And now it seems her kids are following in her nutrition-conscious footsteps, because the mum-of-four has revealed the snack she feeds her family after school, and it's certainly not a bag of Hula Hoops or cheeky cereal bar chucked into the backseat of the car mid-school run.

From the look of a behind-the-scenes photo on social media Brooklyn, 18, Romeo, 15, Cruz, 12 and six-year-old Harper tuck into post-school snacks of mixed seeds doused in organic aminos - a gluten-free replacement for soy sauce.

The 43-year-old former Spice Girl shared a candid snap with her 17.2m followers of what looked like a tray of mixed nuts of pumpkin seeds and pine nuts, with a bottle of Liquid Aminos on the side.

Over the image of the oven-roasted nuts, Victoria wrote: 'Seeds doused in organic Aminos! Grilled until crispy! After school snack! Good for mummy too!'

A sneak peek into how she maintains her slender frame, maybe? The star has always been candid about her regime, as she told Vogue Nederland in June: 'I go for a three-mile run every morning and I work out for an hour with a PT, which gives me just enough time to get to the kitchen to puree Romeo's avocados. His toast jumps out of the toaster the minute he comes down for breakfast.'

Victoria - who has been married to husband David since July 1999 - has long been a fan of aminos; in a 2014 interview she revealed she takes a staggering 60 vitamins and supplements a day.

'Twenty-two amino acids, 12 vitamins, 28 minerals,' she told Vogue of her daily routine.

'And please don't write that I'm completely mad!' she joked. 'I need a lot of energy to be buzzing about!'
