Diabetes and The Importance of the Glycemic Index

The Glycemic Index

The glycemic index (GI) is a ranking of carbohydrates on a scale from 0 to 100 according to the extent to which they raise blood sugar levels after eating. Foods with a high GI are those which are rapidly digested and absorbed and result in marked fluctuations in blood sugar levels. Low-GI foods, by virtue of their slow digestion and absorption, produce gradual rises in blood sugar and insulin levels, and have proven benefits for health. Low GI diets have been shown to improve both glucose and lipid levels in people with diabetes (type 1 and type 2). They have benefits for weight control because they help control appetite and delay hunger. Low GI diets also reduce insulin levels and insulin resistance. The good news is there are foods that are low on the GI which you would never expect like PASTA, yes pasta!!

Low Glycemic food is considered less than 55 on the index
Foods with GI between 55 and 70 are considered intermediate
Foods high on the Glycemic Index are more than 70

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.

• Low GI diets help people lose and control weight
• Low GI diets increase the body's sensitivity to insulin
• Low GI carbs improve diabetes control
• Low GI carbs reduce the risk of heart disease
• Low GI carbs reduce blood cholesterol levels
• Low GI carbs can help you manage the symptoms of PCOS (polycystic ovarian syndrome)
• Low GI carbs reduce hunger and keep you fuller for longer
• Low GI carbs prolong physical endurance
• High GI carbs help re-fuel carbohydrate stores after exercise

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

Last but not least here is a really great website that lists quite a lot of foods and their rankings on the GI http://www.glycemicindex.ca/glycemicindexfoods.pdf explore it and do some more research on your own, there is plenty of info out there.
