7 SUPERFOODS Incredibly Low On The Glycemic Index Level

Glycemic load and school performance -

Fat and acid foods like vinegar, lemon juice or acidic fruit slow the rate at which the stomach empties and slow the rate of digestion, resulting in a lower GI. Cooking and processing can also affect the GI — food that is broken down into fine or smaller particles will be more easily absorbed and so has a higher GI.

Foods that have been cooked and allowed to cool potatoes, for example can have a lower GI when eaten cold than when hot for example, potato salad compared with hot baked potato. This is important, as most foods are eaten as part of a meal and this affects the GI value of foods.

For example, eating cornflakes a higher GI food with milk a lower GI food will reduce the overall effect of the cornflakes and milk meal on blood glucose levels. These are examples of nutrition content claims and general level health claims, allowed by Food Standards Australia New Zealand under Standard 1.

The Low GI Symbol and claims about the relationship of a low GI product and its effect on health is only available to packaged food products that meet strict nutritional and testing criteria. This labelling is not compulsory for food companies to follow, so not all products that are eligible will display the symbol or make a claim.

This is often the case for smaller companies who may not have the money to go through the necessary processes to be given the label. The amount of the carbohydrate-containing food you eat affects your blood glucose levels. For example, even though pasta has a low GI, a large serving can still cause the blood glucose levels to rise more rapidly than a smaller serving.

This is what is called the glycaemic load GL. The GL builds on GI, as it considers both the GI of the food and the amount of carbohydrate in a portion.

GL is based on the idea that a high GI food consumed in small quantities would give the same effect on blood glucose levels as larger quantities of a low GI food.

The GL calculation is: GI x the amount of carbohydrates in grams in a serving of food ÷ Using a pasta example:. Here is another example, where both foods contain the same amount of carbohydrate but their GIs are different:. Both the small baked potato and the apple have the same amount of carbohydrate 15g.

However, because their GIs differ the apple is low while the baked potato is high , their GLs also differ, which means the baked potato will cause the blood glucose level of the person eating it to rise more quickly than the apple.

Eating low GI foods 2 hours before endurance events, such as long-distance running, may improve exercise capacity. Moderate to high GI foods may be most beneficial during the first 24 hours of recovery after an event to rapidly replenish muscle fuel stores glycogen.

The GI can be considered when choosing foods and drinks consistent with the Australian Guide to Healthy Eating External Link , but there are limitations.

For example, the GI of some everyday foods such as fruits, vegetables and cereals can be higher than foods to be eaten occasionally discretionary like biscuits and cakes. This does not mean we should replace fruit, vegetables and cereals with discretionary choices, because the first are rich in important nutrients and antioxidants and the discretionary foods are not.

GI can be a useful concept in making good food substitution choices, such as having oats instead of cornflakes, or eating grainy bread instead of white bread.

Usually, choosing the wholegrain or higher fibre option will also mean you are choosing the lower GI option. There is room in a healthy diet for moderate to high GI foods, and many of these foods can provide important sources of nutrients.

Remember, by combining a low GI food with a high GI food, you will get an intermediate GI for that meal. The best carbohydrate food to eat varies depending on the person and situation. For example, people with type 2 diabetes or impaired glucose tolerance have become resistant to the action of insulin or cannot produce insulin rapidly enough to match the release of glucose into the blood after eating carbohydrate-containing foods.

This means their blood glucose levels may rise above the level considered optimal. Now consider 2 common breakfast foods — cornflakes and porridge made from wholegrain oats. The rate at which porridge and cornflakes are broken down to glucose is different.

Porridge is digested to simple sugars much more slowly than cornflakes, so the body has a chance to respond with production of insulin, and the rise in blood glucose levels is less. For this reason, porridge is a better choice of breakfast cereal than cornflakes for people with type 2 diabetes.

It will also provide more sustained energy for people without diabetes. On the other hand, high GI foods can be beneficial at replenishing glycogen in the muscles after strenuous exercise. For example, eating 5 jellybeans will help to raise blood glucose levels quickly. This page has been produced in consultation with and approved by:.
