Lentils have an effect on blood glucose. Eating lentils may cause a temporary rise in blood glucose, but moderate consumption of lentils usually does not raise blood glucose too much. As long as you eat calorie-containing foods, your blood glucose concentration will rise, but eating foods with a lower glycemic index will have less of an effect on your blood glucose; lentils have a glycemic index of 38, which is a low glycemic index food, so eating lentils appropriately will not usually cause a large fluctuation in your blood glucose. In addition, lentils contain vitamin A, vitamin E, vitamin B and other nutrients and are low in calories, so eating lentils appropriately can help replenish nutrients. In daily life, people with diabetes or healthy people should maintain a low-salt, low-fat and low-sugar diet to help keep blood sugar stable.
