Buckwheat flour is ground from buckwheat groats — technically a seed, not a grass — making it naturally gluten-free. It has a distinctive earthy, slightly bitter flavour and provides good protein (relatively high in lysine), useful magnesium, manganese, copper, and resistant starch. It is the traditional flour for galettes, Japanese soba noodles, and Russian blini.
Mix with a neutral flour (rice, tapioca) for lighter gluten-free baking; 100% buckwheat products tend to be dense and crumbly. Hydrate with eggs or extra liquid to improve structure.

Glycemic Index & Load
Medium GI food — moderate effect on blood sugar. Pair with protein, fat, or fibre to lower the overall meal GI.
Glycemic Load (GL = GI × carbs ÷ 100) accounts for portion size. A high GL — keep portions modest.

* % Daily Value is the proportion of an adult
EU Nutrient Reference Value (NRV) supplied by 100g of this food.
NRVs are the labelling standard — the same basis as the “%RI” figures printed on
food packaging — so these percentages are directly comparable with a shop label.
They are a single adult figure and do not vary by age or sex, which is why they
sometimes differ from UK dietary reference values: the NRV for vitamin C is 80mg
where the UK RNI is 40mg. When Nutriofia assesses your own intake in the
reports and trackers, it uses the age- and sex-specific UK values instead.
Fibre is shown without a percentage. Our fibre values use the UK
Englyst NSP method, while the published 30g daily goal is an AOAC figure — the two
are measured differently and a single percentage would mislead.
