In general, individuals with high blood sugar can eat whole grains, but they should be consumed in moderation.

Whole grains, such as brown rice, whole wheat, and oats, are rich in vitamins and minerals. They can help delay the absorption of sugar from food to a certain extent, aid in stabilizing blood sugar levels, and reduce blood sugar fluctuations. At the same time, the dietary fiber in whole grains can slow gastric emptying and has positive effects on promoting intestinal motility and preventing constipation. For individuals with high blood sugar, this makes whole grains a beneficial choice. Therefore, individuals with high blood sugar can consume whole grains.

Although whole grains are beneficial for blood sugar control, excessive consumption may lead to excessive calorie intake, which can negatively affect blood sugar management. It is recommended to consume them in moderation. Whole grains should also be reasonably combined with vegetables, protein-rich foods, and other foods to ensure balanced nutrition. Additionally, cooking methods for whole grains should be considered; prolonged boiling or cooking with added sugar should be avoided to maintain their low glycemic index properties.

To maintain good health, it is recommended to follow a balanced diet, maintain appropriate portion sizes, monitor physical responses, and avoid excessive consumption or eating at inappropriate times.
