The proportion of resistant starch in buckwheat is high, and the fermentation of resistant starch in large intestine can reduce the content of total cholesterol and triglyceride in plasma.
The starch content in buckwheat seeds is about 70%, and there are differences among different regions and varieties. Compared with ordinary grain starch, buckwheat starch is easy to digest and absorb after eating, and has a high proportion of amylose, which can affect the entry of water molecules, delay the gelatinization and digestion speed, thus inhibiting the rapid rise of postprandial blood sugar, and can be used as a good auxiliary food for diabetic patients.
