The same foods on the glycemic index list of foods can have different rankings based on the way they are grown, processed and cooked. This makes following the list confusing at times. Toss in our varying metabolic rates, the quntity we eat and how we combine foods… it can be daunting.
Now figure that are a some inconsistencies in the way the glycemic index list of foods was calculated.
Food with higher levels of carbohydrates tend to be understated in their affect on our blood sugar. This is due to the fact that the rankings are based on an amount of 50 grams which is well below what the average consumer would eat. On the flip side, for the same reasons, the low carbohydrate food’s impact is overstated.
But…there is a solution. To help clear up some of the confusion, nutritionists have developed the “glycemic load” calculation. It’s more accurate because it takes the quantity of carbohydrates like starches and sugars into account, not just the quality, the food’s amount of fiber.
The amount and the way we combine our foods has an affect, like all foods eaten, on our blood sugar levels. Using the “glycemic load” calculation is a more accurate measure of that affect than the glycemic index list of foods alone.
To calculate the glycemic load is fairly simple. Take the food’s glycemic index list of foods ranking and divide by 100. Once you have that, multiply by the number of grams being eaten. This will give you the glycemic load and a better understanding of how a certain food will impact your blood sugar levels and help you manage the unhealthy spiking.
So you know where the foods rank…a load number of 11-19 is medium, below 10 is low and 20+ is high.
Here’s an interesting example. Watermelon. Watermelon ranks high on the glycemic index list of foods. It comes in at around 72. (Based on 50 grams.) There are 6 grams of available carbohydrates per 120 gram serving. Divide 72 by 100, multiply by 6…ta daaa! You get 4.32 which scores low on the glycemic load.
Watermelon carbs score high on the glycemic index list of foods but low on the load list because there just isn’t a lot of it.
If you get a good understanding of the glycemic load and the glycemic index, it will become very clear why it’s important (and healthy) to combine foods from the four food groups.
Proteins and fats slow our digestion and affect our blood sugar levels on a more consistent and healthy pace. That’s why a hand full of Cheerios, which is basically nothing more than refined carbs…has a higher score on both the index and load charts than a scoop of ice cream!
The glycemic index list of foods is a terrific dietary aid all by itself. If you are not the type person to count carbs and do the math, then just follow the list and you will get amazing health benefits. It can’t hurt. But, if you are the detail oriented type, calculating the glycemic load will give you the best and healthiest diet currently know to science.
