au/health/healthyliving/carbohydrates-and-the-glycaemic-indexAccessed on 10 May 2018This website is reliable as it is managed and controlled by the Department of Health and Human Services and was created with its intent being to educate people about the Glycaemic Index.2)2.1. The definition of Glycaemic Index (GI) The Glycaemic Index is a rating of carbohydrates found in foods according to how they affect your blood glucose levels.The difference between Glycaemic Index and Glycaemic LoadThe Glycaemic Index (GI) is a ranking solely based on how the carbohydrates affect your blood sugar.
The Glycaemic Load is a rating based on the combination of the Glycaemic Index and the amount of carbohydrates found in food. The Glycaemic load is defined by the amount of carbohydrates in a portion of food multiplied by the GI value divided by 100.Ref: https://www.gisymbol.com/about-glycemic-index/2.
2. The GI Rating Scale:A low GI has a value of 55 or less. A medium/moderate GI value is 56-69.A high GI value is 70 or more.2.3. What is insulin?Insulin is a hormone produced by the pancreas that enables your body to use sugar (glucose) from carbohydrates in the food you consumed for energy or to store glucose for future usage.2.
4 The ideal blood glucose level in human beings and why is it considered ideal.A human beings ideal fasting blood sugar on awakening should be under 100 mg/dl. Before-meals a normal glucose levels are 70–99 mg/dl and up to 140mg/dl two hours after eating. A person will have diabetes when the fasting blood glucose is level is at 126mg/dl or above. The safe blood sugar level is between 70 to 105mg/dl ensuring that you still have the right amount of energy but your blood glucose levels are never extremely high or extremely low.
2.5 State the classification of foods according to the G.I. rating scale and give 10 examples of foods for each of the 3 groups. Provide the G.

Explain the effects on the body of eating foods from each of the 3 categories according to the G.
I. rating scale.Foods with a High GI can cause a sudden rise in glucose levels due to this the body will pancreas will produce insulin. The high amount of insulin produced causes glucose levels in the blood to suddenly decrease and this create the feeling of hunger even if you weren’t hungry before. Food with a Low GI are good and beneficial to your health as Low GI reduces the risk of chronic disease.
