Foods with high glycemic potential -
Some high GI foods are:. Low or medium GI foods are broken down more slowly and cause a gradual rise in blood sugar levels over time.
Some examples are:. Some low GI foods, such as wholegrain foods, fruit, vegetables, beans and lentils, are foods we should eat as part of a healthy, balanced diet. However, using the glycaemic index to decide whether foods or combinations of foods are healthy can be misleading.
Foods with a high GI are not necessarily unhealthy and not all foods with a low GI are healthy. For example, watermelon and sometimes parsnips are high GI foods, while chocolate cake has a lower GI value.
Also, foods that contain, or are cooked with, fat and protein slow down the absorption of carbohydrate, lowering their GI.
For example, crisps have a lower GI than potatoes cooked without fat. However, crisps are high in fat and should be eaten in moderation.
If you only eat foods with a low GI, your diet may be unbalanced and high in fat. Find out more about eating a healthy, balanced diet. Low GI foods, which cause your blood sugar levels to rise and fall slowly, may help you feel fuller for longer.
This could help control your appetite and may be useful if you're trying to lose weight. However, as mentioned above, not all foods with a low GI are healthy. Therefore, relying on GI alone is not a good way to decide whether foods or combinations of foods are healthy.

However, other factors must also be taken into account. Research has shown that the amount of carbohydrate you eat, rather than its GI rating, has the biggest influence on blood glucose levels after meals.
It's also important to eat a healthy, balanced diet that is low in fat, sugar and salt, and high in fruit and vegetables.
If you've been advised to make changes to your diet, or you need advice, a diabetes dietitian can help you work out a diet plan. Foods with carbohydrates include bread, breakfast cereals, rice, pasta , legumes, corn, potato, fruit , milk , yoghurt , sugar , biscuits, cakes and lollies.
The digestive system breaks down carbohydrates in foods and drinks into simple sugars, mainly glucose. For example, both rice and soft drink will be broken down to simple sugars in your digestive system. The pancreas secretes a hormone called insulin, which helps the glucose to move from your blood into the cells.
Our brain, muscles and nervous system all rely on glucose as their main fuel to make energy. The body converts excess glucose from food into glycogen. Glycogen acts as a storage form of glucose within the muscle tissue and the liver. Its role is to supplement blood glucose levels if they drop between meals especially overnight or during physical activity.
The glycaemic index GI is a way of ranking carbohydrate-containing foods based on how slowly or quickly they are digested and increase blood glucose levels over a period of time — usually 2 hours.
The GI uses glucose or white bread as a reference food — it has a GI score of Carbohydrate-containing foods are then compared with this reference to assign their GI.
This ensures all foods compared have the same amount of carbohydrate, gram for gram. Carbohydrates that break down quickly during digestion have a higher glycaemic index. These high GI carbohydrates, such as a baked potato, release their glucose into the blood quickly.
Carbohydrates that break down slowly, such as oats, release glucose gradually into the bloodstream. They have low glycaemic indexes. The blood glucose response is slower and flatter. Low GI foods prolong digestion due to their slow breakdown and may help with feeling full.
These ranges, along with some example foods, include:. For instance, although both ripe and unripe bananas have a low GI less than 55 , an unripe banana may have a GI of 30, while a ripe banana has a GI of 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.
GI Foods with high glycemic potential, which list many types of Rehydration for hangover recovery and their GIs, are available. The Wtih was introduced in withh David J. Jenkins and co-workers. Glycemix index does not predict an individual's glycemic response to a food, but can be used as a tool to assess the insulin response burden of a food, averaged across a studied population. Individual responses vary greatly. The glycemic index is usually applied in the context of the quantity of the food and the amount of carbohydrate in the food that is actually consumed. As Fods plan pktential meals, you will witb starches and gigh that contain carbohydrates.

A prediabetes diagnosis can be alarming - this condition is marked by abnormally high blood sugar glucosemost often caused by insulin resistance. Prediabetes is the term used to describe elevated blood sugar glucose that has not reached the threshold of type 2 diabetes diagnosis. The key is early intervention — to get your blood sugar out of the prediabetes range. Making a lifestyle change through diet and movement will always be the first line of treatment — so what you eat matters!
