Buckwheat groats are rich in resistant starch that offers the microbiome a valuable food source for those gut friendly bacteria that produce the essential short chain fatty acid n-butyrate. Many ketogenic diets are deficient in resistant starch and its value to the microbiome is well established. The type of resistant starch in buckwheat is also a natural emulsifier that helps keep water-based ingredients mixed with the healthy fats. Buckwheat groats are high in the amino acid lysine, typically missing from plant proteins. Small amounts of buckwheat can add significant amounts of lysine and methionine to help form complete proteins.
