Weetabix is a beloved breakfast cereal in many parts of the world, particularly in the UK, Australia, and New Zealand. Made from whole wheat, it is often perceived as a healthier option compared to other breakfast cereals. One of the key factors that contribute to its reputation as a healthy choice is its Glycemic Index (GI). In this article, we will delve into the world of GI and explore what it means for Weetabix.
Understanding the Glycemic Index (GI)
The Glycemic Index is a measure of how quickly the carbohydrates in a particular food raise blood sugar levels after consumption. It is a scale that ranks foods from 0 to 100, with higher values indicating a more rapid increase in blood glucose. The GI is an essential tool for people with diabetes, as well as those who want to manage their blood sugar levels and maintain a healthy diet.
How is the GI calculated?
The GI is calculated by measuring the blood glucose response to a specific food compared to a reference food, usually pure glucose. A group of people will consume a portion of the test food, and their blood glucose levels will be measured at regular intervals over a period of two hours. The results are then compared to the response to the reference food, and the GI is calculated as a percentage of the reference food’s response.
GI categories
Foods are categorized into three groups based on their GI:
- Low GI: 55 or less
- Medium GI: 56-69
- High GI: 70 or more
