Types of Foods that Have a Low Glycemic Index

The glycemic index or “GI” system of measurement is one way to help determine "good" foods to include in a diabetic diet. The glycemic index measures how much and quickly any given food will increase your blood glucose levels, which is done by measuring the effects of carbohydrates in foods. Knowing what foods have a low glycemic index can help those with Type 2 Diabetes choose more appropriate foods for meal plans or a menu.

The higher the glycemic index of a food, the higher the rate of absorption into the bloodstream. Consuming high-GI foods can make blood sugar levels "spike". Conversely, a low glycemic index means a slower glucose release and is the preferred choice for diabetics as it helps to keep blood sugar levels under control. The glycemic index ranges from 0-55 which is considered low GI; 56-69 which is considered medium GI; and 70-99 which is high.

The glycemic index of any given food is determined by a number of considerations including the type of starch, and the molecular compound of the starch as well as fat and protein. Salt and natural oils and acids can also make a difference, and adding certain ingredients to your meals can heighten or lower its glycemic index.

Those who have a history of diabetes in their family but have not been diagnosed with the disease themselves can take on a low GI diet as a preventative measure as it is known to lower the risk of Type 2 Diabetes. For those who have already been diagnosed, the low GI diet helps to control blood sugar levels.

Processed or refined foods tend to be high GI. Most fruits and vegetables have a low GI. Exceptions are "starchy" vegetables and fruits, such as potatoes and watermelon, which are considered high GI foods. Other low GI foods include whole grain products, legumes, fish, eggs, meat and dairy products, and foods rich in fiber. Try to choose lower-GI foods more often.

Ingredients added to food while cooking or eating can impact the glycemic index of your meal. For example, adding butter or oil or vinegar to your food may lower the overall GI - but adding these things to high GI foods will not make them healthy. A calorie still counts -- eating large amounts of low-GI foods can still mean you take in too many calories. And too many calories means weight gain. A dietician can help you create a sensible eating plan.

Those with Type 2 Diabetes can benefit from a low GI diet as it assists in the management of blood glucose levels.
