Glycemic Index: Benefits And Tips To Follow A Low GI Diet

Medically reviewed by Maria Sarino, MD FACT CHECKED

The glycemic index is a ranking of carbohydrates on a scale from 0 to 100 based on their effect on blood sugar levels.

Foods with a high glycemic index are quickly digested and absorbed into the bloodstream, causing a rapid rise in blood sugar.

On the other hand, foods with a low glycemic index are slowly digested and absorbed, resulting in  slow rise in blood sugar.

If you are interested in learning more about the glycemic index, you have come to the right place. Let’s talk more about the glycemic index here. 

All About Glycemic Index

The Glycemic index is the optimal comparison of the spike in sugar levels after consuming any type of food source that contains any portion of sugar or carbohydrates. 

It was originally developed for people with diabetes as a way to choose foods that would not cause large spikes in blood sugar levels.

However, the glycemic index has been found to be useful for everyone in managing their weight and overall health.

The glycemic index can be a helpful tool in choosing foods that will help you feel full and satisfied after eating.

Foods with a low glycemic index are slowly digested and absorbed, resulting in a gradual rise in blood sugar.

This slow rise in blood sugar helps to control hunger and prevents overeating.

GI Scores

Foods that are high on the GI score raise blood sugar levels more than foods that are low on the GI score.

Here is a list of common foods and their GI scores-

  • White bread: 70
  • Brown rice: 55
  • Oatmeal: 54
  • White potato: 70
  • Yams: 54
  • Corn: 55
  • peas: 48
  • Lentils: 30
  • Chickpeas: 28
  • Black beans: 30
  • Kidney beans: 31
  • Lima beans: 32
  • Garbanzo beans: 35
  • Soybeans: 18
  • Fruits:
  • Apple: 38
  • Orange: 43
  • Banana: 51

Low GI Foods

Low GI foods are often recommended for people with diabetes, as they can help to regulate blood sugar levels.

There are a variety of low-GI foods available, including many fruits, vegetables, and whole grains. Here is a list of some low-GI foods that you can incorporate into your diet:

  • Fruits: apples, oranges, pears, berries
  • Vegetables: broccoli, cabbage, carrots, spinach
  • Whole grains: oats, barley, brown rice, quinoa
  • Beans: lentils, chickpeas, kidney beans
  • Dairy: yogurt, milk, cheese
  • Nuts: almonds, walnuts, pistachios

Low Glycemic Diet

Foods that involve a low glycemic value, tend to be beneficial for everyone as they could assist in managing sudden spikes in sugar levels and generally take more time to get absorbed and digested.

Thus, following a low glycemic diet could benefit people with high sugar problems as the diet could reduce the same in Type 2 diabetes patients.

Replace items with a high GI with those that have a lower GI as part of the low glycemic diet.

Benefits Of A Low Glycemic Diet

The following are the benefits of Low Glycemic diet-

  • Improved Control Of Blood Sugar

    A Low glycemic diet is a diet that consists of foods that have a low impact on blood sugar levels. The glycemic index is a ranking of how foods affect blood sugar levels.

    Foods with a high glycemic index raise blood sugar levels quickly, while foods with a low glycemic index raise blood sugar levels more slowly.

    A low glycemic diet is typically high in fiber and low in refined carbohydrates, such as white bread and sugar.

  • Increased Weight Loss

    Low-glycemic foods have been shown to help with weight loss in several ways. They help to regulate blood sugar levels, which can prevent cravings and hunger.

    Whereas, they help to promote a healthy digestive system, which can further help with weight loss.

    Low glycemic foods, could lead to more weight loss as compared to high glycemic foods as they could help in boosting metabolism in the body.

Tips To Follow A Low Glycemic Diet

If you are looking to follow a low glycemic diet, there are a few things you should keep in mind.

First, you will want to focus on eating mostly whole, unprocessed foods. This means plenty of fruits, vegetables, lean protein, and healthy fats.

You should also avoid foods that are high in sugar and refined carbs, as these can cause spikes in blood sugar levels.

In addition, you will want to make sure you are getting enough fiber. Fiber helps to slow down the absorption of sugar into the bloodstream, which can help to keep blood sugar levels in check.

Last but not least, it’s critical to maintain proper hydration throughout the day by consuming lots of water.

Following these simple tips could help you to successfully follow a low glycemic diet and improve your overall health.

High GI Foods

The following list showcases a variety of high-GI foods. While some of these items may be healthy in moderation, it’s important to be aware of their potential effects on blood sugar levels.

  • White bread
  • White rice
  • Potatoes
  • Corn
  • pasteurized fruit juices
  • Ice cream
  • Candy
  • Soda
  • Packaged snacks
  • Desserts

Benefits of High GI Food

A high GI diet has many benefits, including-

  • Reduced Risk Of Heart Disease

    The glycemic diet is a relatively new way of eating that is becoming increasingly popular among health-conscious people.

    Unlike other diets, the glycemic diet does not restrict any particular food group.

    Instead, it focuses on the glycemic index of foods, which is a measure of how quickly the body metabolizes them.

  • Reduced Risk Of Type 2 Diabetes

    A high glycemic diet has been linked to a reduced risk of type 2 diabetes.

    This type of diet is high in carbohydrates that are rapidly absorbed into the bloodstream, resulting in spikes in blood sugar levels.

    While this may not sound like a good thing, studies have shown that it can actually help to reduce the risk of type 2 diabetes.

    It is thought that the high glycemic diet helps keep blood sugar levels stable, which in turn helps reduce the risk of diabetes.

  • Improved Athletic Performance

    The high glycemic diet has been gaining popularity in recent years, thanks in part to its proven efficacy in improving athletic performance.

    This type of diet is based on the consumption of foods that have a high glycemic index, meaning they are quickly absorbed and metabolized by the body.

    This allows for a quick burst of energy, which is ideal for athletes who need to perform at their best.

    There are many benefits to following a high glycemic diet, including increased energy levels, improved mental focus, and enhanced physical performance.

    If you are an athlete who is looking to improve your game, the high glycemic diet may be right for you.

Cooking And Ripening Effects On GI

Foods with a high glycemic index tend to cause rapid spikes in blood sugar, while foods with a low glycemic index have a more gradual effect.

Cooking and ripening could have a significant effect on the glycemic index of a food. For example, cooked carrots have a glycemic index of 48, while raw carrots have a glycemic index of 30.

This means that cooked carrots will cause a rapid spike in blood sugar, while raw carrots will have a more gradual effect.

Ripening can also affect the glycemic index of a food to a greater extent.

For example, ripe bananas have a glycemic index of 60, while unripe bananas have a glycemic index of 30. This means that ripe bananas will cause a rapid spike in blood.

Final Remark

A glycemic index is a valuable tool that was initially used for diabetics but has been effective in determining measures for those trying to lose weight or other health benefits as well.

Foods with a high glycemic index cause a rapid rise in blood sugar, while low glycemic foods have a slower, more gradual effect.

There are a variety of factors that affect the glycemic index of a food, including cooking methods, ripeness, and processing.

When used correctly, the glycemic index can help people make healthier choices.
