Cookie Crisp Breakfast Cereal

It’s too early to say. The science in this area is still emerging. There is evidence that low GI foods take longer to digest and help you feel satisfied for longer, but none that you’ll eat fewer calories at the next meal.

The serving sizes mentioned on breakfast cereals can slightly differ, mainly due to differences in product density. Beyond its nutrients density, it’s also important for the portion size to suit the average cereal bowl. Some types of breakfast cereals, such as mueslis or granolas, are denser than traditional flakes; so a 30 g serving could look tiny and unrealistic in a bowl – that's why we use 45 g as a reference. These different serving sizes have been defined by the European cereals trade association and consistently applied by all industry members in Europe.

No. Even though some foods made with whole grain have a high GI, you can still benefit by including them in a healthy, balanced diet. Eating lots of whole grain can be good for the heart, even if the GI of the food is high. The whole population can benefit from eating more whole grain; the effect of low GI foods is still not clear.
