Glycemic Index Table

Avocados have a low glycemic index (GI) of 40. Low glycemic index foods are less likely to cause blood glucose spikes. Also, several epidemiological studies have found that replacing saturated fats with unsaturated fats, like avocados, can improve insulin resistance and reduce the risk of type 2 diabetes.¹

Nutritional Facts

Avocados are a great source of fiber and contain more fats than carbohydrates, which makes them extremely popular for people following a low-carb-eating-style. Avocados are also among the highest-fat plant foods, which is why they are included in many vegan and vegetarian diets. The neutral but earthy flavor of avocado allows it to work well in sauces, salad dressings, sandwiches, salads, and more.

Is Avocado Good for Weight Loss?

Avocados can be helpful with both weight loss and weight management. As noted above, avocados are rich in anti-inflammatory properties, improve digestion, and reduce the risk of obesity. Also, they contain less than one gram of sugar, so you can enjoy avocados without losing sight of your wellness goals.

Studies have also shown that avocados can help individuals lose weight by reducing hunger, improving satiety, and raising metabolic rates.⁶

Avocados are also a good source of fiber, which promotes feelings of fullness, slows down digestion, and can help with regular blood sugar levels. These benefits can also assist with appetite control and overall weight loss goals. 

When eating avocados, pay particular attention to portion size. A single avocado (about 150 to 200 grams) can contain up to 300 calories. 

Is Avocado Safe for People Living with Diabetes?

People living with diabetes can certainly eat avocados! Avocados are a low glycemic food, meaning they will not cause high blood sugar spikes. They are also low in carbohydrates and have a high fiber content, which can help regulate blood glucose levels.

Avocados also boost insulin sensitivity, which is common in people living with type 2 diabetes. Avocados help increase insulin action in the body, lowering blood glucose levels.

It is always important to be mindful of portion sizes. While avocados contain many benefits, they do contain a high amount of calories and fat.

What is Glycemic Index?

The glycemic index (GI) is a measure of how quickly a carbohydrate-containing food raises blood sugar levels compared to a reference food, usually glucose. It ranks foods on a scale from 0 to 100, with higher values indicating a faster rise in blood sugar. The glycemic index (GI) scale is typically categorized as follows: Low GI [55 or less], Medium GI [56-69], High GI [70 or higher]. Foods with a high glycemic index digest rapidly and can cause dramatic fluctuations in blood glucose or glucose spikes.

What is Glycemic Load?

Glycemic load (GL) takes into account both the quality (glycemic index) and quantity (carbohydrate content) of carbohydrates in a specific serving of food. It is a measure of how much a particular food will raise blood sugar levels. GL is calculated by multiplying the glycemic index of a food by its carbohydrate content and dividing it by 100. It provides a more accurate representation of the overall impact of a food on blood sugar compared to the glycemic index alone.

Does Avocado Spike Insulin?

Avocado has a low glycemic index and does not cause a significant spike in insulin levels. It is a good source of healthy fats and fiber, which can help regulate blood sugar levels and improve insulin sensitivity. However, it is important to consume avocado in moderation as it is high in calories.

Is Avocado Low Glycemic?

Yes, avocado is considered a low glycemic food. It has a glycemic index (GI) of 40, which is considered very low. This means that it has a minimal impact on blood sugar levels and can be a good choice for people with diabetes or those looking to manage their blood sugar levels. Additionally, avocados are high in healthy fats and fiber, which can help slow down the absorption of carbohydrates and further reduce their impact on blood sugar levels.

Can People Living with Diabetes Eat Avocado?

Yes, people living with diabetes can eat avocado in moderation as it is a low-carbohydrate fruit that is high in healthy fats and fiber. Avocado has a low glycemic index, which means it does not cause a rapid increase in blood sugar levels. However, it is important for diabetics to monitor their portion sizes and overall carbohydrate intake to maintain healthy blood sugar levels.
