Glycemic Index

jennie brand-miller Professor Jennie Brand-Miller
What is the Glycemic Index?

Not all carbohydrate foods are created equal, in fact they behave quite differently in our bodies. The glycemic index or GI describes this difference by ranking carbohydrates according to their effect on our blood glucose levels. Choosing low GI carbs – the ones that produce only small fluctuations in our blood glucose and insulin levels – is the secret to long-term health reducing your risk of heart disease and diabetes and is the key to sustainable weight loss.

What are the Benefits of the Glycemic Index?
Eating a lot of high GI foods can be detrimental to your health because it pushes your body to extremes. This is especially true if you are overweight and sedentary. Switching to eating mainly low GI carbs that slowly trickle glucose into your blood stream keeps your energy levels balanced and means you will feel fuller for longer between meals.

How to Switch to a Low GI Diet
The basic technique for eating the low GI way is simply a “this for that” approach – ie, swapping high GI carbs for low GI carbs. You don’t need to count numbers or do any sort of mental arithmetic to make sure you are eating a healthy, low GI diet.

Use breakfast cereals based on oats, barley and bran
Use breads with wholegrains, stone-ground flour, sour dough
Reduce the amount of potatoes you eat
Enjoy all other types of fruit and vegetables
Use Basmati or Doongara rice
Enjoy pasta, noodles, quinoa
Eat plenty of salad vegetables with a vinaigrette dressing

Glycaemic Index Tables
Finding the GI spot!

Foods only appear on the GI index if they contain carbohydrate. This explains why you won’t find foods like fresh meat, chicken, fish, eggs and cheese in GI lists. However, you may find some processed foods like sausages or chicken nuggets in a GI list because they contain flour!

Low Glycaemic Index foods (55 or less)

Include some of these foods in each meal or snack, but go for low-fat choices where possible, such as skimmed milk. If you want to lose weight, you’ll also need to watch your portion sizes. That means sticking to small servings of pasta and noodles, limiting yourself to two slices of bread with a meal, and having only a couple of squares of chocolate or a small handful of peanuts!
