Editorial & Data Policy

This page explains who creates the content on Glycemic Load Calculator, where our numbers come from, and how we fix mistakes.

Who Writes Our Content

Content on this site is published under the name Glycemic Load Calculator. We don't use made-up authors, credentials or reviews. Our content is not reviewed by a medical professional, so please read our Medical Disclaimer and talk to your doctor or a registered dietitian about your own health.

Where Our Numbers Come From

• Glycemic Index: lab-tested values match the averages in the International Tables of Glycemic Index and Glycemic Load Values: 2008 (Atkinson, Foster-Powell and Brand-Miller, Diabetes Care). Other values are labeled as estimates.
• Carbohydrates and fiber: our database lists total carbohydrate per 100 g of each food. Where we could match a food to the USDA National Nutrient Database for Standard Reference (SR28), we add its fiber value and the calculator uses net carbs (total minus fiber). We only accept a match when the food name and the carbohydrate value agree; foods without a reliable match keep total carbs.
• Formula and bands: GL = GI × available carbohydrate ÷ 100, with Low at 10 or less, Medium at 11 to 19 and High at 20 or more.

What the Labels Mean

• Lab-tested: matched to a published average from human testing.
• Estimate: not yet matched to a published test. It may be close, but treat it as approximate.
• No GI: less than 2 g of carbohydrate per 100 g. Foods like butter, meat, oils and most cheeses don't have a meaningful GI.

How We Check Content

We test the calculator against worked examples before every update. Health statements on our pages are backed by the studies and institutions listed in each page's references, with links where they come up. We avoid claims that a food treats, cures or prevents any condition.

Corrections

If you think a value or statement is wrong, use our contact form and choose “Data correction”. Please include the food name and a link to your source. When a correction holds up, we update the database and every page that uses the value.

Advertising

This site may show ads to cover its costs. Advertisers have no say in our content or our data. Ads are kept separate from the calculators and never appear inside a calculator or its results.
