The Truth About White Bread: Why It’s Time to Switch to a Healthier Alternative

What Impact Does White Bread Have on Blood Sugar Levels?

What is GI

White bread has a GI of between 75 and 90 – so not far off pure sugar, and will therefore have the same effect on blood sugar levels. Within a short time of peaking, these levels will crash and we’ll be left craving more sugar for an instant energy hit.

Wholemeal bread has a GI of around 65 and is considered a medium GI food. Therefore, it still has an impact on blood sugar levels, but this impact is more gradual and provides a more sustainable form of slow-release energy.

Foods that cause rapid blood sugar spikes are linked to an increased calorie intake, obesity, type 2 diabetes, heart disease and strokes.

If you have type 1 or 2 diabetes or you’ve been told you have prediabetes, it’s important to listen to the advice of your medical team and nutritionist. However, since white bread has such a dramatic effect on blood sugar spikes, it’s best eaten in strict moderation or even avoided.
