whey protein isolate and blood sugar

We do not have a blood-glucose figure for whey protein isolate. It is not in the published tables and we could not place it against a food of the same type, so this page leaves it blank rather than filling it in.

Insulin index

Not measured

no figure we are willing to print

Unknown

Not enough data. We could not place this food against either a published table or a food of the same type, so there is no insulin index figure here. An empty space beats a number nobody stands behind.

Glycemic index

Not measured

no figure we are willing to print

Why there is no milligram figure here

A glycemic index is measured on a food. "Your blood sugar will rise by X" is a claim about a person, and it depends on the rest of the meal, the cooking, and you. We show the band and the published index, and we do not invent the reading — this app does not take blood.

See it on a real plate

The scanner works out the glycemic load from the portion in front of you — the index multiplied by the carbohydrate actually there.

Frequently asked

Does whey protein isolate raise blood sugar?›

We do not have a glycemic figure for whey protein isolate. Rather than print a plausible one, this page leaves it blank.

Why does this page show a band and not a blood-sugar number?›

Because we would have to invent the blood-sugar number. A glycemic index is a measured property of a food; "your blood glucose will rise by X" is a claim about you, and it depends on the rest of the meal, how it was cooked, and your own physiology. This app does not take blood, so it does not print a reading.

Is a low glycemic index the same as low insulin?›

No, and on this site you can see the gap. Protein raises insulin while barely moving glucose, so meat, fish and whey sit at the bottom of this scale and well up the other one. The insulin side of this food is a separate measurement.

How does my portion change this?›

The index does not change — it is a property of the food. What scales with your portion is the glycemic load: the index multiplied by the available carbohydrate actually on the plate (a 1 scoop (31g) here), divided by 100. A food with a high index and almost no carbohydrate carries a small load.

Glycemic figures are reference values for whole foods, most of them estimated and every one labelled. Not medical advice, not a prediction of your own blood sugar, and independent of the carb alarm. If you manage diabetes, your own meter and your own clinician beat any table.
