What is the Glycemic Index and Glycemic Load?

Glycemic this and glycemic that. Does it matter?

You’ll notice that they both begin with “glycemic.” That’s one tip that they have to do with sugars and carbs. Not only how much sugar is in foods, but more importantly, how it affects your blood sugar levels.

In general, diets that are high on the glycemic index (GI) and high in glycemic load (GL), tend to increase the risk of diabetes and heart disease.

FUN FACT: Starches like those in potatoes and grains are digested into sugar; this is because starch is just a bunch of sugars linked together. Digestive enzymes break those bonds so that the sugars become free. Then those sugars affect your body the same way that eating sugary foods do.

 

GLYCEMIC INDEX (“HOW FAST”)

The most common of the two terms is “glycemic index” (GI).

As the name suggests, it “indexes” (or compares) the effect that different foods have on your blood sugar level. Then each food is given a score from 0 (no effect on blood sugar) to 100 (big effect on blood sugar). Foods that cause a fast increase in blood sugar have a high GI. That is because the sugar in them is quickly processed by your digestive system and absorbed into your blood. They cause a “spike” in your blood sugar.

So, you can probably guess that pure glucose is given a GI rating of 100. On the other hand, chickpeas are right down there at a GI of 10.

Regarding GI: low is anything under 55; moderate is 56-69, and 70+ is considered a high GI food.

Remember, this is a measure of how fast a carbohydrate containing food is digested and raised your blood sugar. It’s not a measure of the sugar content of the food.

How the carbohydrates in food affect your blood sugar level depend on other components of the food. Things like fiber and protein can slow the release of sugar into the bloodstream, and this can make even a high-sugar food, low on the GI scale.

So, lower GI foods are better at keeping your blood sugar levels stable because they don’t increase your blood sugar level as fast.

FUN FACT: Can you guess which food has a GI of higher than 100? (Think of something super-starchy) White potatoes! They have a GI of 111.

 

GLYCEMIC LOAD (“HOW MUCH”)

The glycemic load is different.

Glycemic load (GL) doesn’t take into account how quickly your blood sugar “spikes”, but it looks at how high that spike is. Basically, how much the food increases your blood sugar.

GL depends on two things. First, how much sugar is actually in the food. Second, how much of the food is typically eaten.

Low GL would be 0-10, moderate GL would be 10-20, and high GL would 20+.

 

EXAMPLE OF GL AND GI

So, let’s compare average (120 g) servings of bananas and oranges:

Food GI Serving size (g) GL per serving
Banana, average 48 120 11
Oranges, average 45 120 5

Excerpt from: Harvard Health Publications, Glycemic index and glycemic load for 100+ foods

As you can see, the banana and orange have almost the same glycemic index.; this means they both raise your blood sugar in about the same amount of time.

But, the average banana raises the blood sugar twice as high (11) as the orange does (5). So, it contains more overall sugar than the same amount (120 g) of orange.

Of course, this is all relative. A GL of 11 is not high at all. Please keep eating whole fruits. 🙂

 

WHAT DOES THIS ALL MEAN FOR YOUR HEALTH?

Certain people should be aware of the effects that foods have on their blood sugar. People who have diabetes or pre-diabetes conditions like insulin resistance need to be aware of the glycemic index and glycemic load of foods they are eating regularly.

The GI and GL are just two factors to consider when it comes to blood sugar. Some high GI foods are pretty good for you but if you want to reduce the impact on your blood sugar, have them with a high-fibre or high-protein food.

 

CONCLUSION

If you have blood sugar imbalances or diabetes, you should probably be aware of the GI and GL of your food.

If you are at risk of diabetes or heart disease, you might try swapping out some higher GI/GL foods and replacing with lower GI/GL foods.

Oh, and try this low GI recipe I have for you.

Ready for the truth no one wants you to know?

There actually IS a secret tool to getting healthier.

Here’s another secret:
It DOESN’T involve giving up treats and wine forever.

In fact, the way I’ve been able to keep my family and I healthy for the last decade has been largely thanks to the 80/20 rule.

This week’s blog (link below) is ALL about moderation. The word you hear SO MUCH, but never really know how to practically include in your life.

Also on the blog, 15 DELICIOUS (and I mean actually delicious) vegetable recipes.

No, I’m not going to tell you to make a plain salad with a drizzle of balsamic vinegar.

Let’s talk about VEGGIES that are delicious and taste like our favourite comfort food.

When we start to rekindle our flame with veggies, we remember how good they can taste and how they make us FEEL.

What’s your favourite FUN way to include veggies in your diet?

I really enjoyed reading your blog on Veggies! I like the different ideas on how to incorporate more veggies. I love grilled veggies the best but also enjoy making casseroles with different veggies! I cant wait to try some of your new veggie recipes....even the butternut smoothie😬!

If you have some nagging symptoms, its possible that theyre related to the foods you eat!

And were not just talking digestive symptoms.

Even things like headaches, joint pain, or eczema can be related to food that youre sensitive to.

How would you find out if there is a food at the root of your issue?

Through an elimination diet!

Elimination diets are just that - eliminating certain foods. Then you reintroduce them back one at a time to see if you are sensitive to those foods.

It’s a strategic process that can be great… but also not so great.

In this weeks blog - link below - I share the pros and cons of elimination diets and my latest recipe - youll never know that it eliminates the most common allergens (because its so good).

Did you know that your morning coffee can be HARMFUL to your health based on your genetics?

Have you ever wanted to know what you should and shouldn’t eat, based on YOUR specific body?

Todays blog - link below - is ALL about the details of DNA testing AND how to get started.

It looks at your genes and how your diet interacts with them.

We can use nutrition to create PERSONALIZED diets to:

PREVENT certain conditions

Help you understand your INTOLERANCES

Know how your body REACTS to carbs, fats, proteins, vitamins, and minerals

Build a nutrition plan for OPTIMAL health

 

🙋🏻‍♀️ I know I carry the CT variant of the GLUT2 gene.

This means I have a higher risk of sugar addiction which can lead to developing Type II Diabetes – but it doesn’t mean I WILL develop diabetes. 

 

Ive been able to ALTER and IMPROVE my diet with this knowledge to make sure I live a long and healthy life.

 

So, let’s get started figuring YOUR genetics and health out!

Have you tried genetic testing?
