Why the Glycemic Load and Glycemic Index Matter – GI Chart for 100+ Foods

For those who have yet to get acquainted with the term ‘glycemic index, it is a value that is assigned to all sorts of foods based on how quickly or how slowly they cause an increase in one’s blood glucose levels. Overly high blood glucose levels (also called blood sugar levels) can be very dangerous to one’s health. They can cause kidney failure, blindness, and increase one’s risk of cardiovascular disease. In other words, they are toxic and one should avoid high blood sugar levels at all costs. Foods that rate low on the GI (glycemic index) scale have a tendency to release glucose steadily and slowly. On the other hand, foods that rank high on the GI scale tend to release glucose at a much faster pace. And a rapid release of glucose into one’s system is no good for anyone. So it’s no wonder that the foods low on the GI scale support lower size and number on the scale. But those high on the GI scale are also useful for something. Namely, they can help with the recovery of energy after a workout. That is why long-distance runners, for example, would favor high glycemic foods, while those with prediabetes or diabetes would opt for the ones lower on the scale. This is because the steady release of glucose the low glycemic foods offer helps keep blood glucose under control. Something every person with the condition could benefit from, and even those who do not have it.

But There’s More to It

The food’s glycemic index is not the entire story. It fails to inform one how high their blood sugar spikes when they are ingesting the food. This partly depends on the number of carbohydrates in the serving. In order to understand the full effect each food has on us, we would not only need to know how quickly the glucose enters our bloodstream but also how much glucose is delivered in the first place. This is where a different value called ‘glycemic load’ comes into the picture. We can determine it by first multiplying the grams of the carbs in a serving by the GI, then divide it by 100. A glycemic load above 20 is considered high, and one below 10 is considered low. In order to help us fully understand how our blood glucose levels are impacted by what we eat, here is an abbreviated chart of 100 foods with their glycemic index and their glycemic load per serving.
