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.
