Bad news if you've only just learned how to pronounce quinoa - because buckwheat is fast stealing the fashionable food's crown as the "pseudocereal" of choice for celebrity chefs and savvy shoppers.
The popular Sirt Food Diet is also thought to be behind a boom in buckwheat sales.
British supermarkets Waitrose and Sainsbury's report surging demand for the gluten-free seed, which can be used to make porridge, granola, risotto and in salads, or for baking as flour.
First sown on the plains of South East China around 6,000 BC, buckwheat is not a grain but like quinoa is a "pseudocereal" - a non-grass used in similar ways to cereals.
"It's a great alternative to rice and quinoa and is perfect for our gluten-free customers," said Chris Whittaker, a grocery buyer who says buckwheat sales are up 80 per cent year on year.
