Simple Steps To A Low Glycemic Index Diet
Have you read about this recently? over the last 30 years,
research into food and blood glucose response has completely
changed our carbohydrate classification system.
It has been learned that it is impossible to predict the impact
on blood glucose levels by certain foods, instead people are fed
carbohydrate foods and the response measured.
This response is known as the Glycemic Index (GI), it is a
measure of how quickly carbohydrate foods are digested and
absorbed, and ranks carbohydrate foods according to their impact
on blood sugar (glucose) levels: as indicted by elevated blood
glucose.
Foods with a high GI are absorbed quickly into the blood stream
and cause a rapid rise in blood glucose levels. While foods with
a low GI are broken down more slowly over time and keep blood
glucose levels more stable (Remember that low is slow!).
Some carbohydrate foods will maintain your energy levels for
hours, while some may cause your blood glucose to rise and fall.
Different types of carbohydrate can also affect feelings of
fullness in the stomach and this can influence hunger and your
ability to control your body weight.
Why is the GI important?
When our blood glucose levels are stable we have plenty of
readily available fuel for the brain and muscles. If our blood
glucose levels drop too low (hypoglycaemia) we feel tired, dizzy
and generally unwell. If our blood glucose levels rise too
quickly a rapid drop usually follows this.
Include low glycemic index foods in meals and snacks to slow the
release of glucose into the bloodstream. A low glycemic index
snack a few hours before exercise will help maintain your energy
levels for more effective training.
After high intensity exercise (strength training) a high
glycemic index snack should be consumed within 30 minutes. This
will help to replace energy and start the recovery process.
Low-GI foods take longer to digest and help delay hunger pangs
that little bit more and thus promote weight loss. So please
choose your carbs carefully as this will lower your insulin
levels and burn more fat. The secret is to swap high GI foods
with low GI foods.
