Low GI carbs -

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:.

About the glycaemic index GI Foods and drinks provide our body with energy in the form of carbohydrates, fat , protein and alcohol. Digesting and absorbing carbohydrates The digestive system breaks down carbohydrates in foods and drinks into simple sugars, mainly glucose.

The glycaemic index GI 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.

These ranges, along with some example foods, include: low GI less than 55 — examples include soy products, beans, fruit, milk, pasta, grainy bread, porridge oats and lentils medium GI 55 to 70 — examples include orange juice, honey, basmati rice and wholemeal bread high GI greater than 70 — examples include potatoes, white bread and short-grain rice.

Glycaemic load GL The amount of the carbohydrate-containing food you eat affects your blood glucose levels. Calculating glycaemic load GL The GL calculation is: GI x the amount of carbohydrates in grams in a serving of food ÷ GI and exercise Eating low GI foods 2 hours before endurance events, such as long-distance running, may improve exercise capacity.

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

Where: GI is the GI value using the glucose scale; Carbohydrate per portion is total digestible or available carbohydrate, and because the GI is a scale from 0 to that is expressed as a percentage, 1 unit gram, or g of glycemic load is equivalent to 1 gram of glucose.

For example, a single apple has a GI of 38 and contains 13 grams of carbohydrates. We can therefore predict that the potato will have more than double the glycemic impact of an apple 12 vs 6. Similar to the glycemic index, the glycemic load of a food can be classified as low, medium, or high:.

Low: 10g or less Medium: 11 — 19g High: 20g or more. The GL of a mixed meal or diet can simply be calculated by summing together the GL values for each ingredient or component.

For the whole day, a target GL of g has been recommended for people consuming 8, kJ calories. If you use the GI as it was originally intended — to choose the lower GI option within a food group or category — you will be selecting the one with the lowest GL. Foods are grouped together for a reason — they contain similar nutrients, including amounts of carbohydrate.

Several factors influence how fast a particular carbohydrate raises blood glucose levels, including how refined or processed the carbohydrate is, the chemical and physical structure of the carbohydrate-food fruit sugar, fructose, has a different structure to ordinary sugar, sucrose, for example , how the carbohydrate is cooked, and other substances in the food such as fibre or acid — which help to slow the speed of digestion and in turn lower the GI value.

This is one of the most important factors that determines the GI of foods. The carbohydrate becomes incapable of resisting the digestive enzymes and is therefore rapidly metabolised into glucose. The body processes glucose very efficiently, the GI of glucose is ; it cannot metabolise fructose — or fruit sugar — as easily, which is why fructose has a low GI of Ordinary table sugar, sucrose, is made up of one molecule of glucose linked to one of fructose meaning the GI of table sugar is midway, at The physical structure of the carbohydrate also affects the GI value.

Most breads are in the high GI range — not due to the chemical nature of wheat starch, but for two physical reasons:. Pasta has a GI value of which can be reduced by cooking it less.

Fibre either in the carbohydrate itself or in the stomach protects the starchy carbohydrate from rapid attack by digestive enzymes, and slows digestion in the digestive tract. Both of these consequences ultimately slow down the conversion of the carbohydrate to glucose.

The more fat or acid a carbohydrate food contains, or the more fat or acid in the stomach during digestion , the slower the carbohydrate food is converted to glucose and absorbed into the bloodstream. Fermenting foods or the sourdough method of baking bread also lowers the GI.

Protein will stimulate additional insulin secretion, resulting in lower blood glucose levels. Protein and fat both tend to delay stomach emptying, thereby slowing the rate at which carbohydrate can be digested and absorbed. This means a high fat meal will have a lower glycemic effect than a low fat meal, even if they both contain the same amount and type of carbohydrate.

A low GI diet focuses on the quality of carbohydrates you eat. Good carbohydrates or low GI carbohydrates are more slowly digested helping keep your blood sugars stable, whereas bad carbohydrates cause your blood glucose levels to peak and crash.

Most breads are in the high GI range — not due to the chemical nature of wheat starch, but for two physical reasons: The fine particle size of wheat flour gives digestive enzymes greater surface area to attack and metabolise the bread; The surface area of bread particularly white bread , is also increased by its puffed-out, fluffy structure.

This results in the GI being significantly raised by these structural attributes. How carbohydrates are cooked or prepared Pasta has a GI value of which can be reduced by cooking it less.

For example, even though pasta has a low IG, a large serving can IG 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 hightheir 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 Linkbut 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.

The glycemic load GL is a measure of the type and quantity of the carbs you eat. Diabetes is a complex disease that affects millions of people worldwide 6.

Those who have diabetes are unable to process sugars effectively, which can make it difficult to maintain healthy blood sugar levels. However, good blood sugar control helps prevent and delay the onset of complications, including heart disease, stroke, and damage to the nerves and kidneys 7 , 8 , 9.

A number of studies suggest that low GI diets reduce blood sugar levels in people with diabetes 10 , 11 , A review of 54 studies concluded that low GI diets reduced hemoglobin A1C a long-term marker of blood sugar control , body weight, and fasting blood sugar levels in people with prediabetes or diabetes The low GI diet may also improve pregnancy outcomes in women with gestational diabetes , a form of diabetes that occurs during pregnancy.

The low GI diet appears to reduce blood sugar levels in people with diabetes. Diets higher in GI have also been associated with an increased risk of type 2 diabetes. Low GI diets have been associated with a reduction in weight and cholesterol.

On the other hand, high GI diets have been linked to heart disease and an increased risk of certain cancers. There are plenty of healthy and nutritious foods to choose from.

You should build your diet around the following low GI foods:. These foods can be included as part of the low GI diet:. To search for foods not found on this list, refer to this database.

The low GI diet involves swapping high GI foods for low GI alternatives. For a balanced diet, consume low GI options from each of the food groups. To follow the low GI diet, limit your intake of the high GI foods listed above and replace them with low GI alternatives. This sample menu shows what 1 week on the low GI diet might look like.

It even includes a few recipes from the Glycemic Index Foundation. The sample meal plan above shows what 1 week on the low GI diet might look like. However, you can adjust the plan to suit your taste and dietary preferences.

Eating snacks between meals is allowed on the low GI diet. Some healthy snack ideas are listed above. For example, the GI of frozen french fries is Some varieties of baked potato, a healthier alternative, have a GI of 93 or more. In fact, there are many unhealthy low GI foods, such as a Twix bar GI 44 and ice cream GI 27—55 for low fat versions.

Another drawback is that the GI measures the effect of a single food on blood sugar levels. However, most foods are consumed as part of a larger mixed meal, making the GI difficult to predict in these circumstances However, this is an important factor in determining their effect on your blood sugar levels.

However, watermelon also has a low carb content, containing under 8 grams of carbs per grams. In fact, a typical serving of watermelon has a low GL of 4—5 and a minimal effect on blood sugar levels This highlights that using GI in isolation may not always be the best predictor of blood sugar levels.

The low GI diet has its drawbacks.

Glycemic Index: What It Is and How to Use It It matters how the food is prepared and how it is processed. 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. Glucose, or pure sugar, has a GI of while foods that contain zero carbohydrates, such as steak, have a GI of 0. Low-GI diets could benefit overall health as they generally reduce the intake of added sugar, ultra-processed foods, and refined carbs, all of which have a high GI. The GI indicates how quickly carbohydrate-containing foods increase blood sugar levels, compared with pure glucose. Delahanty LM.

Low and medium GI foods

Back to Food and diet. The glycaemic index GI is a rating system for foods containing carbohydrates. It shows how quickly each food affects your blood sugar glucose level when that food is eaten on its own.

Carbohydrate foods that are broken down quickly by your body and cause a rapid increase in blood glucose have a high GI rating. 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. Both of these consequences ultimately slow down the conversion of the carbohydrate to glucose. The more fat or acid a carbohydrate food contains, or the more fat or acid in the stomach during digestion , the slower the carbohydrate food is converted to glucose and absorbed into the bloodstream.

Fermenting foods or the sourdough method of baking bread also lowers the GI. Protein will stimulate additional insulin secretion, resulting in lower blood glucose levels. Protein and fat both tend to delay stomach emptying, thereby slowing the rate at which carbohydrate can be digested and absorbed.

This means a high fat meal will have a lower glycemic effect than a low fat meal, even if they both contain the same amount and type of carbohydrate.

The goal of such diets is to help people maintain healthy blood sugar levels and reduce their risk for diabetes , heart disease, and other health problems. The Glycemic Index GI measures the impact of carbohydrates on your blood sugar level.

Foods are given a number from 0 to based on how quickly they cause your blood sugar to rise after you eat them. Foods with higher GIs can cause rapid spikes in blood glucose while those with lower GIs have less of an effect. Low GI foods include whole grains, legumes, fruits and vegetables as well as dairy products like milk and yogurt which all contain fiber or fat that slow digestion time making them more slowly absorbed by the body than high-GI items like white breads or sugary snacks.
