The Ultimate Guide to the Glycemic Index of Every Food Imaginable

The glycemic index (GI) is a ranking of foods based on their ability to raise blood sugar levels. It's a powerful tool for managing blood sugar and making informed choices about the foods you eat. In this guide, we'll explore the GI of various foods, including grains, fruits, vegetables, legumes, dairy, and more.

Understanding the Glycemic Index

The GI is a scale from 0 to 100, with higher values indicating a greater impact on blood sugar levels. Foods with a GI of 55 or less are considered low-GI, while those with a GI of 70 or higher are considered high-GI. The GI of a food is not a measure of its nutritional value, but rather a reflection of its ability to raise blood sugar levels.
