EXPERT VERDICT: Glutenfree, these are just 96 per cent buckwheat — which has been ‘ puffed’ to a rice cake- like texture — and chia seeds.

Buckwheat is a good source of manganese, important for enzyme production and metabolism. Chia seeds are a source of heart-friendly omega 3 fatty acids. High in fibre, just three of these provide over a tenth of your recommended daily intake, almost a third more than you’d get in a medium slice of wholemeal bread.

TASTE: A slightly bland, nutty rice cake. 8/10
