When you eat rice, bread, or any other typical food high in carbohydrates, it is digested by the stomach and small intestine, where it is absorbed into the blood as glucose. Figure 1 shows how it is absorbed into the body. Figure 1: Absorption of glucose
When glucose enters the bloodstream, insulin facilitates its uptake into the body's cells. When an excess of glucose is ingested, insulin over secretion occurs. Insulin increases the biosynthesis of fat and suppresses its breakdown. Thus, it becomes easier for fat to accumulate in body tissues. Blood sugar level will not drop if the sugar in the blood is not properly processed due to, for example, too little insulin being secreted, or resistance to the action of insulin. If blood sugar levels have not decreased several hours after eating on a regular basis, this indicates a susceptibility to diabetes. To avoid this and stay healthy, we should eat types of foods that will not cause a sudden, extreme rise in blood sugar levels. What is BMI?
What is a healthy blood sugar level
Blood sugar level rises every time you eatWhat foods do not raise blood sugar level much?High calorie foods may or may not cause the blood sugar level to riseMany people think that all high-calorie foods raise blood sugar level, but this is not always the case. In general, foods that cause blood sugar level to rise the most are those that are high in carbohydrates, which are quickly converted into energy, such as rice, bread, fruits and sugar. Food containing three major nutrients
Carbohydrates do raise blood sugar levels quickly. However, recent studies have shown that even amongst foods that have the same amount of carbohydrates, there are two categories: those that cause a sudden rise in blood sugar levels and those that cause a more moderate rise, depending on the amount of dietary fiber contained. It is important to know which foods are low GI and which are high GI.The University of Sydney has defined foods with a GI value of over 70 as "high GI foods," foods with a GI value of between 56 and 69 as "mid-range GI foods," and foods with a GI value of 55 or under as "low GI foods", when using glucose as the reference food (where glucose = 100). Because high GI foods cause a sudden spike in the blood sugar level, large amounts of insulin are secreted in order to process the sugar in the blood, causing a spike in insulin secretion to handle the sugar. When low GI foods are eaten, the sugar is gradually absorbed into the body so the blood sugar level rises gradually. Thus, an appropriate amount of insulin is secreted and sugar is promptly taken up by the tissues. Thus, knowing which foods are low GI foods (causing moderate amounts of sugar to be absorbed) is very important to living a healthy
life. GI of main food

In a healthy person, insulin then starts working, and the blood sugar level returns to the pre-meal level 2 hours after eating.
Does blood sugar drop 2 hours after eating?Reactive hypoglycemia occurs when your body experiences low blood sugar after a meal. “It typically occurs about 2 hours after a meal,” says Zumpano, “and can sometimes even happen up to 4 hours after eating.”
What should blood sugar be 3 hours after eating?Here are the normal blood sugar ranges for a person without diabetes according to the American Diabetes Association: Fasting blood sugar (in the morning, before eating): Less than 100 mg/dL. 1-2 hours after a meal: Less than 140 mg/dL. 2-3 hours after eating: Less than 100 mg/dL.
What is normal blood sugar level after 2 hours meal?What Are Normal Blood Sugar Levels? They're less than 100 mg/dL after not eating (fasting) for at least 8 hours. And they're less than 140 mg/dL 2 hours after eating.
