The Japanese believe that eating soba noodles means to live a longer life. Compared with egg noodles or white rice, soba noodles are indeed relatively rich in nutrients.

But its glycemic index is about 59, which is a medium level. If you are concerned about blood sugar you should not eat too much of it.

However, using buckwheat flour instead of white flour can help increase the amount of soluble fiber. For people with diabetes, a high-fiber diet is a very important part of controlling blood sugar.

According to a 2016 study, replacing white bread with buckwheat bread for breakfast can help to improve glucose tolerance.

The US Department of Agriculture data shows that a quarter cup of buckwheat flour contains 3 grams of fiber (11% of the DV) and 1.44 mg of iron (8% of the DV)

Therefore, eating buckwheat from time to time is acceptable for diabetics.
