GI Values Update

Many of the products in GI Values Update are not available in the USA. Why’s that?
The answer is pretty simple. Very few US companies are GI testing their products, and those that are don’t always release the results for publication. Where do the values we publish in GI News come from? We publish the GI values of foods that have been tested by a lab that provides a legitimate GI testing service following the standardised in vivo procedure – and currently there are only a few centres around the world that do this. We also need the manufacturer to give us permission to publish the results. And they don’t always do this. We really do understand how frustrating it is not to be able to find the GI of your favourite foods. We always urge people to hound manufacturers to get their foods GI tested. But we also know that’s much easier said than done, especially when you use the ‘HOW TO CONTACT US’ page on that corporate website. Following a recent press release that was published internationally, we asked Kraft in the US for a few more details about a new ‘healthy’ range of snacks and cereals that they are promoting. We filled in all the ‘compulsory (asterisked) fields, so they probably now know more about us than we do about their products.


GI Group: ‘Have you glycemic index tested your ‘Back to Nature’ granolas, cereals, cookies and crackers? Are any low GI? Are any gluten free? If not do you plan to GI test these products in future?’

Kraft: ‘Thank you for visiting www.kraft.com/responsibility. Unfortunately, we don't have that information available at this time. If you haven't done so already, please add our site to your favorites and visit us again soon!’

Don’t despair. Keep hounding and together we will make a difference. It just may take a bit of time. And please tell us about products you know have been GI tested by an accredited laboratory. The takehome message: Enjoy plenty of the foods that are naturally low GI (legumes/pulses, fruit and vegetables, pasta and noodles, reduced fat dairy foods). To find out more about them, you might like to check out a copy of Low GI Eating Made Easy which has a whole section on the top 100 low GI foods you can tuck into without worrying about brands.

What does the GI symbol mean?
The GI symbol on a food is a guarantee that the stated GI value is reliable and that the food is a healthy choice in its food group. To earn certification, foods that carry the symbol must be a good source of carbohydrate and meet a host of other nutrient criteria including kilojoules (calories), total and saturated fat, sodium (salt), and where appropriate, dietary fibre and calcium. The GI Symbol Program is a public health initiative run by Glycemic Index Limited, a non-profit company whose members are the University of Sydney, Diabetes Australia and the Juvenile Diabetes Research Foundation.

Where can I get more information on the GI symbol program?

I had a question.

I am a recently diagnosed diabetic T2 and I've noticed that food I used to eat before shoots my blood sugar through the roof. Whereas foods I was never very interested in previously has little impact.

For instance, pasta or bagels of any kind (which I love) I can't touch anymore. Whereas things like chocolate-covered strawberries (which I rarely had previously) has scant impact on my blood sugar since I recently was at a party and had two...

Could it be that whatever foods made you diabetic in the first place (T2--insulin resistant) will be the ones that you can't have going forward? In other words your body instantly recognizes them as soon as you eat them and starts generating defenses against them...

Just wondering...

>>>pasta or bagels of any kind (which I love) I can't touch anymore.

Remember portion caution with carb-rich foods such as rice, al dente pasta and noodles, potatoes etc. Eating a huge amount of these foods, even of the low GI ones, will have a marked effect on your blood glucose. Bagels are high GI. A large glucose response would be expected. Instead of high GI packaged white and wholemeal breads, choose a really grainy bread where you can actually see the grains, granary bread, stone-ground wholemeal bread, real sourdough bread, soy and linseed bread, pumpernickel, fruit loaf or bread made from chickpea or other legume based flours.

The GI of strawberries is negligible and the GI of chocolate low because of the high fat content. A scant impact is to be expected.
