GI is an abbreviation for Glycemic Index, which is an index showing the degree of increase in postprandial blood glucose level. In other words, it shows the degree of absorption of sugar contained in food and measures the amount of sugar that enters the blood within 2 hours of ingestion. GI began to come into the spotlight, especially in the 1990s, and the FAO / WHO report was published in 1998. Furthermore, in 2003, WHO reported that "low GI foods may reduce the risk of developing overweight, obesity, and type 2 diabetes", and various studies have continued since then. Food manufacturers wanted to supply foods with high fiber, low energy density, and low GI. Low GI foods are a hot keyword that is attracting attention from the viewpoint of prevention and improvement of obesity and metabolic syndrome, which are rapidly increasing in modern people. The University of Sydney, Australia defines more than 70 foods as high GI foods, foods between 55 and 70 as medium GI foods, and foods below 55 as low GI foods. So what is the difference between foods with low GI and foods with high GI? When foods such as carbohydrates such as rice and bread enter through the mouth, they pass through the esophagus, are digested in the stomach and small intestine, are absorbed into blood vessels as glucose, and are taken into the body in the flow shown in Fig. 1 below. .. Figure 1: How insulin works As in (1), sugar in food is taken into the blood as glucose, and (2) insulin is secreted from the pancreas by increasing glucose. (3) Glucose is taken up by cells such as liver, muscle, and adipose tissue, so the blood sugar level drops to the level before meals. This is the mechanism of a healthy person. When sugar in the blood enters, insulin takes up blood sugar into many tissues. If you consume a lot of sugar, insulin will be excessively secreted. Insulin has the power to increase fat synthesis and suppress lipolysis. Therefore, it is easier for tissues to accumulate fat. If you can't handle your blood sugar well because of low insulin secretion, late secretion, or reduced action, your blood sugar level won't drop. Diabetes is a chronic condition in which the blood sugar level does not drop even several hours after eating. For these reasons as well, in order to maintain good health, diet and quality are required so that the blood sugar level does not rise sharply after meals. What I want to think about here is GI. Foods with a high GI raise blood sugar levels at once, so a large amount of insulin is secreted or the secretion cannot keep up with the processing of sugar in the blood. Conversely, in foods with a low GI, sugar is taken up gently and the blood sugar level rises slowly, so sugar is quickly absorbed by tissues without secreting too much insulin. to the top home Otsuka Group Otsuka Holdings Otsuka Pharmaceutical Factory Taiho Pharmaceutical Co., Ltd.
