Core Insights - The article emphasizes that not all whole grains are effective in controlling blood sugar levels, with some "pseudo whole grains" having a faster glycemic response than refined grains like white rice and flour [2][6]. Group 1: Types of Grains - Certain sticky grains, such as glutinous millet and black glutinous rice, have a higher glycemic index and can raise blood sugar levels quickly [3][6]. - Whole grains like oats and red beans contain more resistant starch, which has a lower impact on blood sugar due to their tightly packed structure [5]. Group 2: Consumption Methods - The method of consuming whole grains can significantly affect their glycemic index; grinding grains into powder and mixing them with water can increase their glycemic response [9][11]. - For individuals needing to control blood sugar, it is advisable to choose whole grains that maintain a low glycemic index even after processing, such as green beans and lentils [11]. Group 3: Dietary Recommendations - It is recommended to combine whole grains with protein and fiber-rich foods, such as milk and vegetables, to mitigate blood sugar spikes [8][13]. - A balanced intake of whole and refined grains is suggested, ideally maintaining a ratio of 1:1 or 2:1, depending on individual digestive health [14].
