Is a low glycemic index always better?

Not universally. While low-GI foods are generally better for blood sugar control, other factors like overall nutrition, fiber, and portion size are equally important.

Can the glycemic index of a food change?

Yes. Factors like ripeness (e.g., bananas), cooking method, processing, and what you eat it with (e.g., adding fat or protein) can alter a food's GI.

What's the difference between glycemic index and glycemic load?

Glycemic Index (GI) measures the quality (speed) of carbohydrates. Glycemic Load (GL) also considers the quantity of carbohydrates in a typical serving, giving a more complete picture.

Do I need to follow a glycemic index diet?

It can be a helpful guide, especially for individuals with insulin resistance or diabetes. However, it should be one tool among many in a balanced, whole-foods based diet and not followed obsessively.
