GI Food Guide
The following common foods have been split into tables depending on their GI Value
Low GI = GI Value lower than 55
Medium GI = GI Value between 56 and 69
High GI = GI Value between 70 and 100
Quick GI tip: You should be aiming to avoid High GI foods and eat a mix of low and medium GI foods as part of a healthy balanced diet containing good quality protein and fats.

General Guideline
It can be difficult to work out the GI value of some foods without refering to an index or chart, but one rule that you can generally rely on is:
Is the food unprocessed and in its natural state?
Processed food will generally have a higher GI value than un processed and whole foods. For example has it been processed in any of the following ways: cooked, ground up, preserved, had sugar added etc.
Examples:
- A raw carrot has a much lower GI value than a cooked carrot because your body can much more easily digest a cooked carrot and its energy enters your blood faster. So consider eating more raw foods or if cooking vegetables don’t boil them for hours, leave them slightly crispy.
- Museli has a much lower GI value than cornflakes. Again museli is harder to digest because it typically contains whole oat flakes and whole nuts and seeds. Cornflakes on the other hand have been cooked (toasted) and had sugar added.
- Wholegrain bread versus Wholemeal Bread versus White bread. You guessed it, wholegrain bread will have a lower GI value because of the whole grains. Wholemeal bread has a higher GI value because the grains have been ground. White bread is highly processed and has a high GI value.
