Glycemic Index & Glycemic Load

Josh Allen • February 28, 2024

All carbohydrates when digested will raise insulin at different rates. This is called the Glycemic Index (GI) of carbohydrates. If a carb raises insulin quickly, it is considered a high glycemic carb. If it

raises it gradually, it is called a low glycemic carb. 


For the most part, we want to stick to carbs that have a low-moderate glycemic index. There are situations when a rapid blood sugar spike can help. For example, post workout, high glycemic carbs can help shuttle nutrients into the muscles for better recovery.


Very lean individuals who want to build lean muscle can benefit from having high glycemic carbs pre AND post workout. Another example would be someone who is doing an athletic event that requires them to perform for over an hour or more, high glycemic carbs after each event can aid recovery and keep them performing well.


You have to consider how insulin sensitive you are (how well you handle carbs) and what is

the goal you are trying to accomplish when determining what glycemic index of carbohydrates you are going to eat.


The glycemic index of a carbohydrate is represented by a numerical value given to that food ranging from 1-100.


High glycemic index carbs = >70

  • Processed grains ie: white bread/pasta
  • White rice
  • Sweets (cake, cookies, candy)


Moderate glycemic index carbs = 56-69

  • Whole grains ie: whole wheat bread/pasta
  • Basmati, parboiled rice
  • Couscous, quinoa


Low glycemic index carbs = <55

  • Legumes ie: beans, lentils, chickpeas etc
  • Non-starchy vegetables ie: broccoli, spinach, tomatoes etc
  • Fruits ie: cherries, grapefruit, apples etc
  • Whole grains ie: barley, quinoa, oats etc


Here are some examples of starchy carbs rated high to low in glycemic index:




You may notice that potatoes for example have a wide range. This is because the type of potato as well as the cooking method both influence the glycemic index.


High GI potato = White Russet

Moderate GI potato = Red Skinned

Low GI potato = Sweet Potato


A white Russet potato for example has a GI range of 56-100. If you were to boil the potato for a potato salad the GI would be lower compared to if it was baked. 


Boiling potatoes causes them to retain more moisture, which can affect their starch structure and slow down the rate of digestion. Baked potatoes, on the other hand, have a higher GI because the dry heat of baking causes the starches to gelatinize more and break down more quickly during digestion.


Managing Blood Sugar & Insulin


Individuals with insulin resistance should exercise caution when consuming high-glycemic-load carbohydrates due to the heightened release of insulin. An insulin sensitive person on the other hand does not need to worry as much because they release a smaller amount of insulin after eating the same high glycemic index food.


That said, when it comes to controlling blood sugar, it is not all about just glycemic index. Here are 3 other ways to manage blood sugar which could allow you to consume a high GI food without being stressed out about it. 


  • Pairing of Carbs
  • While white bread or rice pasta may have a high glycemic index, when paired with protein, fiber and fats blood sugar can be better managed.
  • If you had a lunch consisting of white pasta (rice or wheat) with only marinara sauce your blood sugar would spike much higher than if the pasta was paired with protein and a salad.

  • Cooking Methods
  • If you are choosing a food like potato that can have a high GI, you can manipulate the GI through the method of cooking. This can be a strategy to improve blood sugar as well.
  • Boiled potatoes will have a lower GI compared to the same quantity of baked potato.

  • Quantity of Carbs
  • It is not just about the GI of a carb but how many carbs are in that particular food. If you are insulin resistant you may not need to avoid a high GI food as much as you may have to just be mindful of the quantity.
  • In general, someone insulin resistant should be very careful with foods that are both high GI and high in carbohydrate



Introducing Glycemic Load


Glycemic load (GL) is a measure that takes into account both the glycemic index of a food and the amount of carbohydrates in a serving of that food. It provides a more accurate picture of how a food affects blood sugar levels compared to just glycemic index alone.


Glycemic load values are typically classified as follows:

  • Low glycemic load: 10 or less
  • Medium glycemic load: 11 to 19
  • High glycemic load: 20 or more
  • 


By considering both the GI and the amount of carbohydrates in a serving, glycemic load provides a more comprehensive assessment of how a food affects blood sugar levels. It's a helpful tool for individuals managing conditions like diabetes or those seeking to control blood sugar levels.


Example 1 (1 cup Watermelon)                    =  (72 X 11g) / 100  =  8 GL


Example 2 (Tim Hortons Blueberry Muffin)   = (80 X 64g) / 100  =  51 GL

It's that time of year again where Halloween candy is everywhere - especially if you have children who are in the trick or treating age. We all know that candy is unhealthy and we are aware of sugar's detrimental effects on our health, from weight gain to cavities... But do you know the risks in eating Halloween candy that go beyond weight gain and cavities? While sugar is certainly a concern, other ingredients in many popular candies can chip away at your health and well-being. The Deceptive Allure of Halloween Treats While eating Halloween candy can be a nostalgic pleasure, the ingredients list tells a different story. I personally love Halloween but about 7 years ago I went clean and gave up Halloween candy for good because I learned it is much more than a sugar problem… Beyond sugar, are ingredients like hydrogenated oils, high-fructose corn syrup, artificial colors, titanium dioxide and common allergens like wheat, corn, dairy, and soy. These ingredients can wreak havoc on our bodies, leading to a host of negative health effects that most consumers overlook. Beware: 5 Ingredients in Halloween Candy With Negative Health Effects 1. Hydrogenated Oils: Hidden Fats Hydrogenated oils transform liquid oils into solid fats and enhance texture and shelf life. These trans fats are notorious for raising bad cholesterol levels, increasing the risk of heart disease and causing inflammation in the body. Look out for the word ‘Hydrogenated’ in candies like Skittles or Starburst 2. High-Fructose Corn Syrup (HFCS): A Sweet Sabotage HFCS is another frequent offender. It’s a cheap, sweet alternative to sugar that can lead to rapid spikes in blood sugar levels and cravings. Overconsumption of HFCS has been linked to obesity, insulin resistance and fatty liver disease. Many people consume HFCS without even realizing it. Candies like Oh Henry and other chocolate bars have HFCS. 3. Artificial Colors: A Rainbow of Risks The colors that make Halloween candy so visually appealing are often the result of artificial colorings like Red 40, Yellow 5 (Tartrazine), Yellow 6 (Sunset Yellow) and Blue 1. Studies have shown links between these artificial colors and hyperactivity in children, as well as allergic reactions as well. Here are some of your Halloween favorites with these colors: Skittles , Maynards , Sour Patch Kids , Jolly Rancher , Twizzlers , Starburst and M&M’s 4. Titanium Dioxide: The White Truth Titanium dioxide is used in many candies to enhance their whiteness and opacity. It is a detergent that damages your gut and decreases your gut microbiome. Any candy that has a white center, like Skittles is known to use this ingredient. 5. Allergens: Hidden Dangers for Sensitive Individuals Finally, we can’t forget the processed allergens like wheat, corn, dairy and soy in many candies like Mars or Snickers . Those who are highly allergic know to stay away from foods with these ingredients but what about the low grade allergic response that most people ignore? Hives, scratchy through, congestions, asthma, sneezing, itchy eyes and mild GI discomfort are all effects of these allergens. The Scary Reality Halloween is a fun time but we’ve really thrown in the towel when it comes to our health based on the things we are accepting as ok. We've created a society where we buy the cheapest, lowest quality candies to give to our children (and ourselves). Most, if not all of the mainstream candy companies produce products that are high in chemicals to preserve shelf life, to entice our eyeballs and to stimulate our brain to want more the moment it hits our palette. We've also bought into the idea that it's ok because it is just once a year... but the reality is that this food is everywhere all the time. If it was just one day on Oct 31 then sure - that could be ok, but most children are coming home with more than 10lbs of candy that they consume over the next 30 days. It’s no wonder why so many of us suffer with health issues including our children. Modern children are being diagnosed with more health problems than previous generations. Things like childhood depression/anxiety, food allergies, ADHD, autism, eczema and obesity are just some of the things we are seeing more of. Stay Vigilant and Read Labels Can we blame our poor health all on Halloween candy? Certainly not - it's more than just candy in October however the amount of candy with the above ingredients being consumed during Halloween and through the year is definitely a contributor. So when it comes to candy, watch out for the sugar but it’s time to wake up to the other ingredients that are damaging us. The best thing to do is read the labels and be aware of what you choose to consume. And hopefully in time we choose to buy 'treats' that are not filled with chemicals. Next year, choose to buy healthier options versus the mainstream candy we grew up with. Healthier Alternatives Here are some options to consider instead of the mainstream low quality garbage that we've been accustomed too: Chocolate Bars Unreal Coconut Bars : This company is on point with way healthier ingredients than the mainstream. They carry an assortment of candies beyond just the coconut bar (which is one of my faves). Granola Bars Made Good : You've probably seen this brand around in stores - specializing in gluten free healthier granola bars. Cookies Simple Mills : Making cookies and baked goods gluten free and with sweeteners that have a lower glycemic index than regular sugar (less of a blood sugar spike) Candies Smart Sweets : Candies without artificial colors and high sugar Lollipops & Jelly Beans YumEarth : W ithout artificial colors Water Enhancer (Vitamin C) Emergen-C : Something different from usual candy - Vitamin C drink crystals that are a much healthier option to candy and kids love em. There are more brands out there but you have to be on your toes when buying. Pay attention to brands, scrutinize the ingredient list and pay the extra money. Every dollar you spend is a vote - the more we vote for the better products for our health, the lower the cost will end up being in the future.

Having trouble controlling the intake of Halloween candy? Unless you are a disciplined ninja or equipped with helpful restraint tactics, you end up eating too much of this low quality, highly processed junk food. If you are someone with a sweet tooth then you are in luck! Here are 5 tactics that will help you avoid eating too much (if any) candy this Halloween. 1)Don’t Skip Meals or Snacks Skipping meals and snacks creates stress on your body and a stressed body is more likely to have sugar cravings. Self control becomes extremely difficult when you're underfed. If candy appears it is much harder to resist because your body is lacking energy, vitamins and minerals. If you eat a solid meal along with healthy snacks throughout the day (ie: protein shake, apple and almonds) I guarantee that it will be hard to eat candy. 2)Eat Enough Protein On the heels of not skipping meals, make sure each meal has enough protein. Meals that are low in protein mean that they are higher in carbs. As a result you will deal with blood sugar dips and greater hunger, weakening your resistance to candy. How much protein? This differs between people but generally you aim to have at least 0.8 grams of protein per pound of ideal body weight. The more active you are, the more protein you will require. 3)Stay Hydrated Being dehydrated will make you feel hungry even when you are not actually hungry. As a result you are more likely to have the urge to grab a sweet from the candy bowl. The simple solution is to just drink enough water throughout the day. How much water?

By then it’s too late. This may sound strange but as you are picking up the candy - say out loud “I am going to eat this candy” (even if no one is around). This helps you become more aware of your actions, encourages mindfulness, and engages your logical mind. 5)Educate Yourself The scary truth is that mainstream Halloween candy is some of the worst food you can put into your body. Most of these candies contain highly inflammatory ingredients, allergens, and toxins known to disrupt everything from the gut microbiome to DNA, potentially contributing to ADHD symptoms and triggering allergies… And that’s without commenting on the effects of sugar that most of us already are aware of. Eating certain candies can be just as bad as smoking a cigarette! Give these tactics a try - they should help you to say no to Halloween junk food this year. If you are still having trouble, you can attempt a ‘clean sweep’ by throwing it all into the garbage… If you still have a sweet craving, have some dark chocolate or walk to the best bakery in town and buy yourself a $10 chocolate croissant :) Happy (Healthy) Halloween!
